Air cylinder and Air valve

admin — Mon, 02 Nov 2009 02:14:09 +0000

Compact, composite Air Cylinders are double acting, with a single rod end. The barrel is made from a unique cross-wound thermo set epoxy. This creates a very strong and lightweight cylinder. The high impact resistance reduces the chances of cylinder failure due to dings or dents. Just try and dent or ding one of these things. I dare you! Air Cylinder heads are clear anodized aluminum alloy with stainless steel tie bolts, so they are much more than just a pretty face.

More specifically - compressed air valves - are discussed on this and the linked pages.

2/2 Air Valves

First, we will talk about a family of fairly simple air valves designated as 2/2 air valves.

The air valve designation 2/2, or perhaps it might be noted as 2/2 NC or 2/2 NO, means the following:

the compressed air valve has two working ports – one for air supply in, and another for air supply to the application. Air piloted 2/2 valves may also have a third air port for the pilot signal to shift the valve.
it can only be shifted into one of two positions – either it’s opened (something flows through it) or it is closed (nothing flows through it)
it is normally open (NO) or normally closed (NC) in its un-actuated, resting state

Reciprocating Seals for Hydraulic Cylinders

admin — Fri, 25 Sep 2009 06:31:11 +0000

The most common fluids used in hydraulic cylinder systems are mineral oil based. In recent years, there has been a lot of attention paid to environmentally acceptable hydraulic fluids, but their use, so far, is limited, mainly because of their relatively high-cost compared with mineral oil. In many cases, standard reciprocating seals can be used in these fluids. Fire resistant fluids, such as high water based fluids, have applications in particular areas such as long-wall mining and have led to the evolution of specialised seals, but the vast majority of applications use hydraulic mineral oil. Two main factors affecting mineral oil based systems are cost and leakage.
Cylinder Tube Manufacture
Hydraulic cylinder tubes are generally made from steel which is drawn over a mandrel (DOM). This process work hardens the material and gives it desirable mechanical properties. The final tube surface is obtained in one of three ways. In the honing process the tube is machined to gain the required roundness and bore tolerance and to remove surface imperfections, then finished by internally grinding or honing. In skived and roller-burnished tube the tube is again internally machined (skived) and flattened by rollers on the machining head. More recently drawing techniques have been developed such that the tube is considered ready to use in the as drawn state. This is known as special smooth inside diameter (SSID) or ’smooth bore’ tube.

In terms of finished tube cost the ranking starting with the cheapest is SSID DOM, roller burnished and honed. SSID DOM tube can be 30% cheaper than roller-burnished, so its attractions to the pneumatic cylinder builder are obvious. However, the quality of such tubes can be an issue which could lead to premature seal failure.
The Limitations of As-Drawn (SSID) Tube
SSID tube has been found to have limitations in application, particularly where the double acting piston seal is being driven into pressure. This can happen, for instance, when the lowering of a load is being controlled by the release of fluid from the full bore. The process of manufacture of as-drawn tube results in axial scoring of the tube; in roller-burnished and honed tube, such defects are eliminated by the finishing of the tube in a circumferential direction. These axial scores can provide sites for the fluid to jet over the seal eroding the contact face, particularly when the seal is being driven into pressure. A further difficulty is that such defects are not detected by the usual methods of surface finish measurement.
Hallite Seals carried out a series of tests where the leakage performance of five different wipers working with a common polyurethane rod seal was assessed. It is shown that he wiper is an important factor in the control of leakage from the hydraulic cylinder gland. Single lip wipers can give a much greater leakage than the seal, on its own, without a wiper. This is the result of the wiping lip collecting the oil on the rod, which provides the boundary lubrication to the seal. The use of double lip wipers reduces the leakage to the level of that of a seal on its own, but there is a danger of pressure trapping between the seal and the wiper. A double lip wiper profile has been developed, which minimizes the ring of oil on the rod collected by the wiping lip, and also has a venting feature to release the oil in the case of a pressure build up between the seal and wiper.

Stainless Steel and Air Cylinders Use

admin — Tue, 22 Sep 2009 00:58:19 +0000

Stainless steel cylinders are utilized in situations where, for hygienic causes, the cylinder would be exposed to precise cleaning or in situations that are sarcastic by nature. Generally the various styles of stainless steel pneumatic cylinders are available in the market.
Pneumatics is characteristically the technology of option for applications such as material handling and small-parts assembly, but with new competences counting closed-loop control, precision pneumatic components and high-speed electronics which have made these techniques more competitive with electrical and hydraulic closed-loop techniques. In industrial relevance’s across the plank, pneumatic cylinders and components are gaining wider recognition as being rocky adequate to withstand unsympathetic situations while offering highest performance at a competitive cost.
We need to also consider that pneumatic cylinders have developed into an almost endless collection of configurations, sizes and extraordinary designs. Such adaptability makes more pioneering configurations probable, but at the same time in some cases it increases sources of failure.
As a thumb rule we should always choose a mounting technique that absorbs force on the cylinder’s centerline. If the piston rod is loaded chiefly in compression form, a better option is to choose a cap-end mounting style. On the other hand, if the piston rod is loaded chiefly in tension, a head-end mounting is the favored best practice. Moreover in all the situations, cylinder’s mountings should be checked on a regular basis.

Air cylinders are pneumatic linear actuators determined by pressure differential in the cylinder halls. One side of a piston flange could be hassled to give force and motion with a spring providing come back force after pressure is released, or both sides can be interchanging pressure for bi-directional powered motion. Air cylinders are used in numerous locations, activating and fastening relevance’s.
There are options for air cylinder mode such as tie rod, smooth body, pancake, rectangular, rotating and multiple bore. The cylinder could be of single or double action. In a single-action device, the air cylinder holds pneumatic porting for drive in just one direction. Single-action air cylinders often integrate a return spring to the unpowered location. In a double action device, both sides of the piston could be pressurized for reversible motion. Force ratings could vary to some extent in opposite directions.

Ergonomic Office Chairs

admin — Mon, 10 Aug 2009 01:20:28 +0000

Seat height
The main criteria for office chairs is that they should be easily adjustable. A pneumatic cylinder adjustment lever or button is the most standard way of operating the gas cylinder to adjust the height of the seat through a distance of approx 480mm - 630mm which should accommodate most users. With the office chair passing through these heights this should allow for the user to have their feet flat on the floor, thighs horizontal and their arms level with the desktop.
Seat width & depth
The width for an office chair varies but is usually around 520mm. The depth should be sufficient to allow the users back to be in contact with the backrest, whilst leaving approx 50mm - 100mm gap between the back of the knees and the front edge of the seat. The front of the seat should also have a pronounced curve which is sometimes called a waterfall edge to relieve pressure from behind the knees. Some office chairs can also be specified with a seat depth adjustment to allow for users with longer legs.
Lumbar support

The lower part of our spine has an inward curve that should be supported when sitting for long periods of time. Most office chairs have some form of basic lumbar support for this region of the back, even if it is just shaped foam beneath the upholstery. Some chairs have a pump-up lumbar bag inserted behind the upholstery which is easily adjustable. Mesh back chairs tend to have a lumbar bar (A shaped piece of rubber or plastic) that can be adjusted in height and depth. Sitting for long periods of time without any kind of lumbar support leads to slouching and bad posture.
Backrest
The backrest of the office chair should ideally be separate to the seat to allow the back to be adjusted independently. This gives the user a fully adjustable chair where the back height can be changed to position the lumbar support in the correct area and the angle to be changed in relation to the seat. The back width can vary depending on design but is generally a similar width to the seat.
If the office chair has the back attached to the seat then the chair should have a tilting mechanism that can be locked when the ideal position has been reached. This style of mechanism should also be accompanied by a tension control to adjust the speed that the back tilts with.
Structure/upholstery/foam/mesh
The seat and back of an office chair can be upholstered in a number of different ways, each having benefits over the other. Some users will prefer a fabric upholstered foam seat & back, others a nylon mesh seat & back or a pneumatic valve combination between the two.
The fabric upholstered foam is the more traditional approach and allows the user to choose from a vast multitude of fabric colours and styles. The mesh is extremely flexible, moulds to the users shape and allows the users body heat to disperse out through the material. The mesh chairs are usually available in a choice of colours. Some more contemporary chairs have moulded plastic backs that offer a more rigid support.
Arm rests
Ideally the arm rests on an office chair should be adjustable, not only in height but in width and depth also. These adjustments will allow the users arms to rest lightly at a comfortable height. The arms should be adjusted so that the users elbows can rest on them whilst typing or using a mouse.
Swivel
All office chairs that are to be used for any period of time should be on a swivel mechanism to allow the user to rotate and reach different areas of their workspace without straining.ork first before making a purchase.
