What are the characteristics of cylinders?

Cylinder refers to a container in an internal combustion engine or an external combustion engine, which allows the piston to live in it and reciprocate up and down. It consists of a cylinder, an end cover, a piston, a piston rod and a sealing element. There are two types of cylinders: reciprocating linear motion and reciprocating swing; When working, the piston should be lubricated by oil mist in compressed air. The piston is the compressed part in the cylinder. In order to prevent the left cavity and the right cavity of the piston from forming a channel with each other, a piston sealing ring is provided. The wear ring on the piston can improve the guiding performance of the cylinder, reduce the wear of the piston sealing ring and reduce the friction resistance. Wear-resistant ring length is made of polyurethane, PTFE, synthetic resin tape, etc. Standard gas cylinder: a gas cylinder widely used in general industry. Compact structure and small volume.

Compared with pneumatic actuator, the structure of electric actuator is relatively simple. A basic electronic system includes actuators, three-position DPDT switches, fuses and some wires, which are easy to assemble. The driving source of electric actuator is very flexible, and the general vehicle power supply can meet the needs, while pneumatic actuators needs air supply and compression driving device. Electric actuator has no danger of "air leakage" and high reliability, while the compressibility of air makes the stability of pneumatic actuator slightly worse. There is no need to install and maintain various pneumatic pipelines. The load can be maintained without power supply, while the pneumatic actuator needs constant pressure supply. Because no additional pressure device is needed, the electric actuator is quieter. Usually, if the pneumatic actuator bears a heavy load, a silencer should be added. The electric actuator is superior in control accuracy. Pneumatic devices usually need to convert electrical signals into pneumatic signals and then into electrical signals, and the transmission speed is slow, which is not suitable for complex circuits with too many component stages.
