The Growth of UAVs and the Risks It Poses to the Public

Posted on by

Unmanned Aerial Vehicles (UAVs) are being used for a number of civilian and commercial purposes, from photography and videography, survey and mapping, inspections, transport to network swarming where they work together to complete a task. This article discusses some of UAV’s current commercial applications and the risk that the growth of UAVs poses on the public.

 

Agriculture and Wildlife

 

UAVs can be used to monitor many aspects of agriculture. Apart from offering an aerial inspection of the crops, they can help in inspecting soil erosion and other parameters that are hard to observe from the ground. In addition to agriculture, they can prove to be quite helpful in forestry too. They can take photos of the forests as well as the wildlife present in them to keep a steady count of the animals living in there. Moreover, they can be used to assist in putting out forest fires that may erupt from time to time.

 

Security and Law Enforcement

 

The borders as well as internal security can be very well taken care of with unmanned aerial vehicle technology. They can also play a crucial role in law enforcement too. They can be used for assisting the police in catching criminals and collecting evidence, search and rescues, surveillance and more.

 

Commercial Sector

 

UAVs may replace manned vehicles in the commercial field as some services have little need for human involvement, including transporting commodities from one place to another with ease.

 

Despite all of the promise that UAVs have shown, the commercial use of these aerial vehicles is still in its initial developmental phase. You may not see transport activities being carried out with the help of UAVs in the near future because of the risks they pose.

 

Safety Risks Related to UAV Transport

 

It is the duty of the national airspace authority to make sure that the airspace remains safe. However, unmanned aerial vehicle transport poses a great threat to airspace safety as it is extremely hard to control the drone’s flight pattern especially when it is flying into an area where various airplanes carrying passengers and goods are present. The following are some of the safety risks that may arise because of UAV transportation.

 

Air Collisions

 

The risks of air collisions increase when an airborne vehicle is not operated by a sensible and trained pilot. So, when we are talking about a UAV which isn’t controlled by any pilot, the chances of a collision happening in the air multiply greatly. While the pilot of a manned aircraft can detect the presence of vehicles flying in their vicinity and take evasive action quickly, a drone cannot make that call unless it is directed to do so from the ground. Thus, UAVs are more likely to get involved in an air collision than piloted aircraft. Unless this safety issue is resolved, the future of UAV transport looks questionable.

 

Ground Collisions

 

It is not only the collision of the UAV with other aircraft in the air that may cause great damage. They can collide with objects on the ground too, causing damage to both people and their properties. There is always a possibility of the UAV going berserk due to loss of signal from the operator or some technical fault in the system. This will pose a risk of the UAV falling from the air and crashing in a populated area. This may lead to the debris entering the houses or people getting killed as a result of the direct impact.

 

System Reliability

 

When it comes to relying on the devices and gadgets solely based on technology there is always an apprehension because of the history of failures that one has seen through the years. UAVs controlled from the ground that are operated using human intelligence can be manipulated as the on-ground pilot take decisions based on the situation. However, such systems too have been seen to crash and become the major cause of loss of lives during transport. The most common reason for accidents of this sort has been failure of various parts and machinery of the aircraft. So, when it comes to leaving decision making to machines that only operate as per pre-fed instructions, the risk of accidents increases many folds. It will take a lot of research and analysis to produce a system that is reliable in future. However, as of now the use of UAVs is still under observation and it will take many more years for them to share the airspace with manned aircraft.

 

Insurance Issues

 

Getting insurance is also an important issue as people find it extremely hard to get their UAVs insured. The main problem cited by many insurance providers is the susceptibility of the system to failure. In addition to this, the safety issues related to the UAVs is another concern why insurance companies are reluctant to insure these aerial vehicles.

 

Privacy and Security Issues

 

Privacy is a major concern associated with drone use as no one wants UAVs peeping into their homes while flying past them. Moreover, the UAVs themselves are not very safe and can be hacked any time. If a drone is hacked by terrorists then they can use it for their ulterior motives, risking the life of millions.

 

So, because of all of these issues and concerns, governments all over the world are reluctant to go forward with unmanned aerial vehicle transport for now.

The Advantages of Using an Adjustable Seatpost with Your Cycle

Posted on by

One of the most highly demanded and a favored product by cyclists around the world is the adjustable bicycle seatpost. In the past, cyclists relied on fixed seatposts, where the height of the seat could only be increased or decreased by adjusting the seatpost clamp through the manual operation of wrenches. But, the use of it has brought a sort of revolution in the world of cycling. Only a simple push of a remote button switch mounted around the handle that is connected by a wire enable riders to increase or decrease the height of the seat, even while riding. Also known as a dropper seatpost, the innovative product is steadily winning the hearts of cycling enthusiasts.

 

Easy to Fit in Your Cycle

 

Riders do not need to buy a new special model of cycle so as to put a new adjustable seatpost. Manufacturers commonly produce adjustable seatposts in the BMX industry standard outer diameter of 27.2mm, making it usable across several varieties of bicycles. Adjustable seatpost with outer diameters of 30.4mm, 30.9mm and 31.6mm are also widely available in the markets.

 

Unparalleled Comfort

 

Different seating positions are required for easy maneuvering of the cycles across different terrains. All cyclists must have experienced that the position which would seem to be absolutely comfortable on a straight road could be really be hard around difficult uphill or downhill terrain. But being able to control the size of the seat with an adjustable seatpost, offers riders the flexibility to comfortably navigate across different terrains.

 

Higher Efficiency and Stability While Riding

 

When the adjustable seatpost is up, pedaling becomes more efficient as cyclists can use the whole range of motion of their leg muscles. When the trail points downhill, dropping the seat allow cyclists to lower their center of gravity, in turn providing more riding stability. Thus, the rider has the freedom to choose the best seating position, based on their need to either ride faster or roll comfortably. All ‘Tour de France’ riders use adjustable seatpost with their cycles because of this very reason.

 

Different Variations Available in the Market

 

Several manufacturers currently produce different variants of adjustable bicycle seatposts based on different technologies. The most advanced as well as costly versions are operated by hydraulics. Similarly, there are also seatposts that are operated by air pressure. But the most commonly available ones are spring based variations. Hydraulics and air pressure operated seatposts require higher maintenance and are vulnerable to leaks, while spring operated versions often last longer and are easier plus cheaper to maintain.

 

Buy the Adjustable Bicycle Seatpost That Gives You the Best Value

 

Whether you are an urban rider or an adventurous mountain bike rider, seek the dropper seatpost that provides you the best value. Choose a product that is comfortable to use but isn’t too expensive to buy and maintain either. Spring operated versions could be one of the better choices. However, in case of heavy duty mountain bike riding getting a hydraulic version can be worth it as well.

What Are the Different Types of Metal-working Machinery?

Posted on by

Metal-working machinery includes a wide variety of equipment used to cut and shape metal. These machines offer an alternative to shaping these metals by hand, resulting in greater precision and higher production levels. They can be found in many metalworking shops, manufacturing and industrial facilities throughout the world, as well as in the homes of hobbyists. Metalworking machines come in many forms, including lathes, milling machines, and planers. This equipment also includes basic tools used to modify the surface or finish of metal, including grinders, polishing equipment, and embossing machines.

 

Lathes are one of the most widely used types of metal-working machinery. These devices rotate a metal object around a spindle. As it rotates, tools and cutting bits shape or cut the metal into the desired form. These machines can range from small desk-top units to large floor models. While some may be manually operated, most rely on computer programming using computer numerical control (CNC) software.

 

The milling machine can be thought of as a more advanced version of the lathe. This metal-working machinery holds an object in place as the worktable moves around it. Unlike the lathe, milling machines can modify metal across three dimensions, not just two. Micro milling machines can even be used to cut and shape items that are invisible to the naked eye. Like a lathe, milling equipment generally relies on CNC software for precise control and programming.

 

A metal planer can be used to cut or shave metal in a single linear direction. These machines hold the metal object stationary, and then run a cutting blade across the surface to smooth or flatten the material. Planers can also be used to cut slots or other shapes into the face of a product.

 

Metal-working machines can also include equipment used to bend and shape sheet metal. For example, a metal brake creates folds or bends in sheets of steel and other metals. Similar machines are used to stamp or emboss patterns into metal, or to roll it flat. These machines can be either manually operated or controlled using a CNC system depending on where they are used.

 

Extruding and casting equipment are other types of metal-working machinery. In casting, workers make a mold of an object and use it to shape molten metal. Extrusion involves forcing hot metal through a die. The shape of the die determines the shape and profile of the final product.

 

SEHO provides much different second hand metal-working machinery such as CNC grinding machinery etc. machine tools. If you are interested in learning more information about used machinery, welcome to visit our website and feel free to contact with SEHO Industry Co., Ltd.

Glass Fibers and Fiberglass Fabrics Information

Posted on by

Glass fibers and fiberglass fabric consist of bulk, chopped fibers or continuous strands of glass. Glass fibers and fiberglass fabric is used in reinforcing plastics and composites as well as other specialized electrical and thermal applications. Fiberglass cloth is frequently used to reinforce other plastic materials. Glass fiber reinforced plastic (GRP) or glass fiber reinforced epoxy (GRE) are commonly called fiberglass.

 

The glass fiber used to create fiberglass material is made by extruding very thin strands of silica-based monofilament. Glass is a unique amorphous solid, meaning it doesn’t have an underlying crystalline structure in the solid state, but rather behaves like a very viscous liquid. Glass fiber lends itself to woven fabric because the thin fibers can easily bend. Fabric made of glass fibers has high tensile strength, dimensional stability, high heat and fire resistance, as well as resistance to many chemical compounds. Fiberglass fabric is also used to dissipate heat, and has electrical properties that make it useful in electronic components.

 

Applications

Glass fibers and fiberglass fabrics are commonly used in composite construction, including materials used in boat building. Light weight fiberglass cloth is used with a resin to produce a waterproof surface. Heavier woven fiberglass fabric can be used for greater strength and rigidity.

 

Glass fibers and fiberglass fabrics are also used to create combination or specialty fabrics. Glass fibers and fiberglass fabric may be combined with carbon fiber or aramid fibers to make laminates and moldable fabrics for canoes, kayaks, and other high strength, low weight applications.

 

Standards

Glass fibers and fiberglass fabrics must adhere to certain standards and specifications to ensure proper design and functionality.

 

Delphi DX300340 – This specification covers the properties of a Polyamide 6, 40% glass filled, impact resistance modified injection molding grade used for the manufacture of parts that require high stiffness and toughness under extreme conditions (Example: airbag containers).

 

GMW15890 – This specification covers the properties of polypropylene reinforced with long glass fibers. It covers injection molding types for manufacturing of technical parts requiring high structural stiffness.

 

JIS C 6832 – This standard specifies the dimensions, transmission requirements, mechanical requirements, environmental requirements and the test methods of silica glass multimode optical fibers using silica glass as a core and a cladding.

A Wonder in the Materials World: Stainless Steel Sheet

Posted on by

Material scientists have created stainless steel, the most versatile alloy which can be seen in its many applications because of its corrosion resistant properties

 

The introduction of a minimum of 12% chromium into the steel alloy renders it corrosion resistant. This resultant product is called stainless steel sheet. There are many grades according to the alloy content and they are named variously as austenitic, martensitic, ferritic, precipitation hardening, super and duplex alloys.

 

Popular Grades of Stainless Steel

 

Austenitic grades of alloys which are stainless and non-magnetic. These cannot be hardened by heat treatment. Commonly used austenitic alloys are iron-chromium-nickel steels. The common grades are the 300 series which are used for their stainless properties and unusually good mechanical properties. The basic grade of this series is the 304. The L grades of this series are the low carbon grades (as in 304l) which provide extra corrosion resistance after welding. The carbon content is kept at 0.03% or less to avoid carbide precipitation. Higher carbon content is useful when the metal is subjected to very high temperatures and has to retain its strength.

 

The two other popular grades in this series are 316 and 317

 

Martensitic Grades of Alloys which are corrosion resistant and amenable to hardening by heat treatment. These are chromium steels with no nickel content. They are magnetic. The most common grades in this are the basic 410 and 420, where 420 has increased carbon more than 410 to improve its mechanical properties

 

Ferritic Grades – Even more corrosive resistant than the martensitic grades, these are highly resistant to cracking due to stress related corrosion. These are also magnetic with only chromium and no nickel. They are considered inferior to austenitic grades, but superior to martensitic grades. 430 is the base grade, which is used commonly.

 

Physical Forms

 

They come in a variety of forms like coils, sheets, bars and plates

 

Applications

 

For its easy maintenance and corrosion resistant properties, stainless steel sheets find diverse applications in:

 

  1. Modern architecture

 

  1. Food processing industry

 

  1. Industrial uses, such as chemical and fuel tankers, chemical plants and petrochemical plants, pharmaceutical industries (for hygienic environment)

 

What are Stainless Steel Sheets Standards?

 

There are many world recognized standards of stainless steel sheets which categorize the stainless steel sheets into different grades as explained above. These may be voluntary grading agencies, country specific agencies or associations of steel producing companies in a particular country. Sometimes any grade of steel marketed by a company will mention different standards of grading having been applied to it.

 

How the Demand for Stainless Steel Plated is satisfied?

 

There are suppliers worldwide who have industry specific grades available for their customers. They have websites and can be contacted easily for further details through a ‘contact us’ webpage. They are also present in social media like Facebook and Twitter. It does not matter if the supplier is from another country in this era of globalization. There is not much difference in the way of doing business.

 

Future of the Stainless Steel Sheet Industry

 

Since stainless steel sheet is such a versatile material, there is ongoing research and more grades are added to the existing ones as they are developed and tested, having unique qualities and different applications

 

The invention and countless applications of stainless steel sheet is a real wonder in the materials world and the future of the steel industry is bright with companies worldwide engaged in supply of this wondrous alloy.

How do Pilot Operated and Direct Operated Solenoid Valves Work?

Posted on by

What are Solenoid Valves?

A solenoid valve is an electro-mechanical valve that is used to control the flow of liquid or gas. The solenoid starts by converting an electrical signal into a mechanical movement. The signal is then sent to a coil and the movement then occurs inside of the valve. Solenoid valves are usually be described as pilot operated or direct operated/acting.

 

Pilot Operated Solenoid Valves

2 way pilot operated solenoid valves have two chambers separated by a diaphragm. The upper chamber is connected to upstream through a pilot hole in either the cover or diaphragm. The media exerts a pressure that acts on the upper side of the diaphragm and keeps the valve closed. When the coil is charged the core lifts off the orifice seat allowing the operating chamber to de-pressurize. The thrust of the upstream pressure under the diaphragm continues, lifting the diaphragm and opening the valve.

 

Pilot operated solenoid valves only operate with a suitable upstream pressure differential and do not operate at zero pressure. Also a minimum pressure differential across the valve is required to keep them open or closed. Pilot operated solenoid valves can provide high flow rates at high pressures with lower power consumption.

 

Direct Acting Solenoid Valves

Direct acting solenoid valves do not use a diaphragm, their seal is part of the moving core. Two way NC direct acting solenoid valves have a spring that holds the core against the seal. When the coil is charged the spring is overcome and the seal is lifted from the orifice seat thus opening the valve and allowing the media to pass through the valve.

 

Two way NO direct acting solenoid valves have a fixed core which usually in the bottom section of the armature tube. The armature is located in the upper part of the valve. A stem passes through the fixed core and is coupled to the seal. This is held off the seal by means of a spring and makes a seal when the coil is energized, thus closing the valve.

 

Three way direct acting solenoid valves work in almost the same way as a two way direct acting solenoid valve. The fixed core has an exhaust orifice running through it. The plunger has an upper seal and lower seal allowing flow to or from either the body seat or exhaust.

 

Direct acting solenoid valves are used when there is no line pressure applied. Typical applications would include a cleaning line when a pump supplies bursts of water through the line. A direct operated solenoid valve would remain closed, even when no pressure is being applied (i.e. in between the busts of water). This is in contrast to a pilot operated valve, which requires some pressure for the valve to stay closed.

What is a Die Sinker EDM Machine?

Posted on by

A die sinker EDM machine is an industrial machine, used to create highly precise forms and structures onto metal plates. A die sinking EDM machine is used to manufacture moulds and templates, as well as press and injection moulds. The mass production of metal reforming, or plastic products with consistent high quality and highly precise dimensions, would only be possible with a die sinker EDM machine.

 

Highly Precise Cutting Using Sparks and Arcs

Since the invention of electricity, it is known that sparks can leave marks on metal surfaces. The cutting effect of electric arcs was only first researched in detail in 1770 by the British scientist, Joseph Priestley. The idea of finding a practical use for it arose over 150 years later. Two brothers from Russia, B.R. and N.I. Lazarenko, researched electric discharging as a new processing method for metal surfaces. These basic technological principles for utilization that they developed are still valid today.

 

Wire Erosion Discharge Machining – The Opposite of Welding

In principle, erosion is very similar to build-up welding. However, the erosion process is done backwards. During welding, material is applied to a workpiece and during erosion, the material is (with help of a conductor and high levels of electricity) evaporated off the workpiece. Using defined intervals and transitions, the metal is broken out of the block of steel with micrometer levels of precision. Despite the small work stages, spectacular sparks are still visible. The accumulation of sparks has no influence, however, on the precision of the surface area. The principle behind this is very simple: different polarized potential is applied to the workpiece and the conductor.

 

The evaporation of the material always takes place, where the distance between the electrodes is the smallest. That is how contours are produced, that cannot be exceeded in terms of precision. Burn and corrosion damages to the conductor and the workpiece can be avoided, as long as the erosion process completely takes place in a conductive, liquid medium. Die sinking should not be performed by assistants or temporary workers. It is essential to have extensive training and a lot of experience, in order to successfully manufacture workpieces through die sinking. For this reason, working with die sinker EDMs should only be conducted by specialists.

 

What can be Produced Using Die Sinking?

When working with a metal workpiece, the processing options with a die sinker EDM machine are unlimited. The erosion conductor can be moved in every direction using its 5 axel head. This freedom of movement allows for the processing of highly complex forms. Die sinker EDM machines are therefore much more efficient than CNC-milling machines. The erosion process is contact-free, which means that expensive drilling, milling or rotating tools are not needed.

 

Even pressing and punching tools are generally made out of specifically strong steel that resists machining operations. With normal CNC-processes, this process will wear out and ruin the tools and machines. With the contact-free erosion process, the hardness and firmness of a steel work tool plays no role. Because of the contact-free erosion process, die sinking EDM machines are durable and steady.

 

OSCAMRAX has been totally dedicated to design and manufacturing of electrical discharge machines and die sinker EDMs over many years. Our objective is to subvert the general impression of low machining speed of EDMs. Therefore, we have spent great efforts in developing high speed EDM machining technology, where to create the best results in speed, accuracy and surface roughness.

 

We offer the most comprehensive range of models including traditional type, CNC type and multiple 6 axes type in order to satisfy the market requirements precisely. If you need more information about EDM machines, welcome to visit our website and feel free to contact with OSCARMAX.

A Discussion on Hand Tree Saws, Pruners, and Other Arborist Equipment

Posted on by

As a dedicated arborist, you need to make sure you have the right tools to perform your job correctly, safely and utilizing your time. Of course, you want to keep the trees you are working in healthy and looking good. That means getting your hands on the best tree pruner, hand tree saw, and other arborist equipment. After all, the difference between doing a good job and a great job not only requires your skills but also your tool selection. Don’t let anyone tell you otherwise.

 

The Difference between Types of Tree Saws

 

When shopping for hand tree saws, you will come across various types of teeth and shapes of blade. These are not mere differences in aesthetics. Each has its own functional purpose. Here is a quick breakdown to guide you in selecting the right saw for your job:

 

  • Curved blade – Do you need a bit of control when cutting branches in tight areas? Do you need to cut quickly and speed up the job? Then this is the piece of arborist equipment for you.
  • Straight blade – A smoother cut at a slower pace than the curved blade. Hey you have to give a little to get a little right? Well, with the straight blade you also get the ultimate control.
  • Blades with gullets – Need something for bind free cutting? This is your ticket.
  • Fine teeth – Delicate cuts for smaller pieces of wood require smaller teeth. They will give you that beautiful, manicured look.
  • Large teeth – Obviously, these teeth come in handy when cutting larger branches. They work faster as you are not as concerned about making the cut perfect for the eye to see.

 

As you use your tree saw, keep in mind that you aren’t using a traditional hand saw. The term “saw” may imply that you move the piece of equipment back and forth to cut the wood. Not the case here whatsoever. Instead, make sure you use a downward stroke to cut the limb in one motion. Having trouble? Perhaps you need to replace your blade. They wear down faster than you might think making cutting more difficult.

 

Pruning Arborist Equipment

 

Poles, sheers, loppers-what are they and what are they for? Well, first of all you have the pole, which allows you to reach branches at various heights. Many arborist equipment suppliers allow you to build your own pole kit. That means you choose the head, base, and middle section to piece together for your required length. Most poles have interchangeable saw or pruner heads. Pruner poles come in wood, fiberglass landscape series, fiberglass professional series, fiberglass telescoping series and fiberglass dielectric series, which are poles that are foam filled for working around electricity. Silky Hayauchi poles extend to 21’ and come with saw blade only. The Silky Hayate extends to 20′ and is a saw blade only.

 

Sheers and loppers that are sold in arborist stores are of professional grade. They are for people who want an easier tool to use with continued performance year after year. Marvin brand shears and loppers are made from forged steel. These tools are not only great for the professional arborist and landscaper but general gardeners will appreciate their performance and lasting quality.

 

Remember, as a dedicated arborist, or even a power gardener, you need to make sure you have high quality arborist equipment.
