As we all know, compared with the electric actuator, the pneumatic cylinder can work reliably under harsh conditions, and the operation is simple, basically can achieve maintenance-free. Cylinders are good at reciprocating linear motion, especially suitable for the most transfer requirements in industrial automation-linear handling of workpieces. Moreover, simply adjusting the one-way throttle valve installed on both sides of the cylinder can simply achieve stable speed control, but also become the largest feature and advantage of the cylinder drive system. Therefore, for users who do not have multi-point positioning requirements, the vast majority from the use of convenience point of view more inclined to use cylinders.
At present, the use of electric actuators in industrial field is mostly required for high-precision multi-point positioning, which is due to the use of cylinders difficult to achieve, back to the second result. And the electric actuator is mainly used for rotating and swinging conditions. The advantage is that the response time is fast, and the speed, position and torque are precisely controlled by the feedback system.
However, when the linear motion needs to be completed, it is necessary to carry out the transmission conversion through mechanical devices such as toothed straps or screw rods, so the structure is relatively complex, and the working environment and the professional knowledge of the operation and maintenance personnel have higher requirements.
