Main structure of electric push rod
Author:
The electric push rod is composed of a driving motor, a reduction gear, a screw, a nut, a guide sleeve, a push rod, a sliding seat, a spring, a shell, a turbine, a micro control switch, etc.
Electric push rod is a new type of electric actuator. The electric push rod is a new type of linear actuator mainly composed of motor, push rod and control device, which can realize remote control and centralized control. The electric push rod moves back and forth within a certain range of travel. Generally, the standard travel of the electric push rod is 100150200250300350400mm. Special travel can also be designed and customized according to different application conditions. The electric push rod can be designed with different thrust according to different application loads. Generally, the maximum thrust can reach 6000N, and the no-load running speed is 4mm~35mm/s. The electric push rod uses 24V/12V DC permanent magnet motor as the power source to convert the rotating motion of the motor into linear reciprocating motion. Push a group of linkage mechanisms to complete the switching of dampers, valves, gates, baffles, etc. Using the electric push rod as the actuator can not only reduce the air supply device and auxiliary equipment required for the pneumatic actuator, but also reduce the weight of the actuator. The pneumatic actuator needs a certain air pressure in the whole control operation process. Although the amplifier with small consumption can be used, the air consumption is still huge over time. The electric push rod actuator is adopted. When the control opening is changed, the power supply is required. When the required opening is reached, the power supply can be stopped. Therefore, from the perspective of energy conservation, the electric push rod actuator has obvious energy saving advantages over the pneumatic actuator. It is suitable for long-distance operation and widely used for the opening and closing, material loading and unloading, flow control, etc. of dampers, valves, gates and other mechanisms in electric power, chemical industry, metallurgy, mining, light industry, transportation, ships and other departments. Now it has been used by more and more departments to replace the automatic device of mechanism hand, hydraulic valve and decelerating transmission mechanism.
