What is the relationship between cylinder and electric actuator?

From the perspective of purchase and application costs, cylinders still have obvious advantages. For pneumatic system, the control system and actuator are very simple. Each cylinder only needs to be equipped with one solenoid valve to switch the gas path and control the movement. The probability of cylinder failure is relatively small, the maintenance is simple and convenient, and the cost is low. For electric actuators, although the acquisition of electric energy is relatively simple and the energy cost is low, the purchase and use cost is high, which requires not only a motor, but also a set of mechanical transmission mechanism and corresponding driving components. At the same time, the use of electric actuators requires many protective measures. Wrong circuit wiring, voltage fluctuation and overload will damage the electric drive, so it is necessary to install protection systems on the circuit and machinery, which increases a lot of extra expenses.
