Electric push rod is a new type of electric actuator, electric push rod is mainly composed of motor, push rod and control device, a new type of linear actuator, which can realize remote control and centralized control. The electric push rod moves back and forth within a certain range of stroke. The standard stroke of the general electric push rod is 100,150,200,250,300,350,400mm. The special stroke can also be designed and customized according to different application conditions. Electric push rod can be designed according to different application loads of different thrust electric push rod, generally its maximum thrust up to 6000N, no-load running speed of 10mm/s, the electric push rod with 24V/12V DC permanent magnet motor as the power source, the motor rotation into linear reciprocating motion. Push a group of connecting rods to complete the damper, valve, gate, baffle, etc. Switching work. Using the electric push rod as the actuator can not only reduce the air source device and auxiliary equipment required by the pneumatic actuator, but also reduce the weight of the actuator. Pneumatic actuators need to have a certain pressure in the whole process of control operation, although small consumption amplifier can be used, but over a long period of time, the air consumption is still huge. The electric push rod actuator needs power supply when changing the control opening degree, and it can no longer supply power when reaching the required opening degree. Therefore, from the point of energy saving, the electric push rod actuator has obvious advantages of energy saving than the pneumatic actuator. It is suitable for remote operation and widely used in the opening and closing, material loading and unloading, flow control of damper, valve, gate and other institutions in power, chemical industry, metallurgy, mining, light industry, transportation, ship and other departments. It has been more and more departments to replace the mechanism hand, liquid grave valve, deceleration transmission mechanism of automatic device.
