Application of pneumatic actuator

pneumatic actuator

At present, the pneumatic actuator is widely used in sewing equipment, especially automatic devices, such as Automatic sewing machine, automatic bulldozer, folding machine,…

  1. Learn about electric and pneumatic actuators – Taiwan Compressor Valves

Electric drives as well as pneumatic actuators are known for a variety of uses. In case you are looking to learn more about these types of actuators hope this article will be exactly what you want.

The concept of pneumatic control system

Electric actuators:

An electric actuator is the use of electrical energy to produce mechanical energy. Meanwhile, pneumatic actuators, which act as air drives, convert air pressure into mechanical force to operate the valve.

Force and High Speed ​​- When it comes to the force and speed of a pneumatic actuator, it is worth noting that they provide more power and speed per unit than electric drives. One can easily adjust the force and speed on the pneumatic actuator. So for those of you needing to control and adjust the force and speed in the system, go for pneumatic actuators without a doubt.

Cost

If you are interested in the cost of pneumatic actuators, then you will be happy to know that the cost is not high. Electric actuators have very high component costs and are therefore avoided.

Cost of maintenance and operation – their maintenance and operation costs are quite high compared to electric drives. These costs include the replacement cost of the vessel, the electric charge, the installation and maintenance of the aircraft, etc.

Heating – the perfect design to counteract its overheating, many of these pneumatic actuators are very popular. In contrast, electric actuators may tend to heat up.

Understanding Electric and Pneumatic Actuators: Moisture – One difference between these two types of actuators is their durability. Although the pneumatic actuator is not sensitive to wet or humid environments, the electric actuator should be kept away from moisture.

  1. Advantages and disadvantages of pneumatic actuator

Advantages:

Due to the high compressibility of the air, it can be easily extracted. Thus, it is possible to apply for the establishment of a compressed air station.

  • Ability to transfer energy far, because the kinematic viscosity of the compressed air and small pressure losses on the pipe.
  • Compressed air is not needed.
  • Low cost to set up a pneumatic drive system, because the majority of compressed air pipeline systems are available.
  • Limited pressure protection system.
Disadvantages:
  • Low transmission power.
  • When the load in the system changes, the velocity changes. Because of the compressive strength of the compressed air, it is not possible to perform straight or rotary movements.
  • The compressed air in the path causes noise.

Nowadays, in the field of control, it is often combined pneumatic control system with electric or electronic. Therefore, it is difficult to determine exactly the pros and cons of each control system.

However, it is possible to compare some aspects of the pneumatic actuator for mechanical, electric drive.

3.Consider buying pneumatic valves

Compressed air Valves

Valves in compressed air are available in both standard and non-standard configurations. Non-standard valves are built according to the manufacturer’s wishes, with port layout, operator style and unique mounting options for their product. They can be inline, side panels can be attached or cross sections are mounted in a row. As each manufacturer does not associate differently, it is better to research the products that fit your application.

4.The most common pneumatic valves

A pneumatic valve is a common pneumatic tool, which plays an integral role in compressed air systems such as steam, water, gas and oil systems. Control flow rates in tools, systems and air motors. Here are some common pneumatic valves.

Electromagnetic Control Valves:

Electromagnetic actuators, solenoid valve, also known as solenoid vavle, are open-close valves with the force of the coil. Depending on the structure, the solenoid valve can be a stop valve (type 1 recess) or a variable displacement valve. Electromagnetic valves are TG codes are cheap, FG code is high-end.

Ex: Electromagnetic valve 4V110, TG 2511-06, TG 3522-08, FG 2521-08, TG 2321-08, …

Mechanical pneumatic valve: Use the muscle to act on the valve. Depending on the needs of the system, you can choose handwheel valve or pneumatic foot pedal. E: TG25-J-08L, TGC34-5, …

Gas control valve: A pneumatic valve to act. Customers can refer to the following mechanical valve lines: Mechanical TG, G322, G321, G522, 4H, …

2-way valve:

This valve is used to open air and water. Valves divided into two types that are normally closed valve and normally open valve. Valves are usually closed when the coil will close when the electromagnetic coil is out of power, automatically opening when the coil is electromagnetic. In contrast, the normally open valve is an open valve when the coil is not electromagnetic and closed when the coil is electrically charged.
