Electric push rod, also known as linear drive, is a new type of linear actuator mainly composed of motor push rod and control device. It can be considered as an extension of the structure of rotating motor. The electric push rod is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. It can be used as execution machinery in various simple or complex processes to achieve remote control, centralized control or automatic control.
The main structure of the electric push rod:
The electric push rod consists of a driving motor, reduction gear, screw, nut, guide sleeve, push rod, slide seat, spring, shell and turbine, Micro control switch and other components.
The electric push rod is a new type of electric actuator. The electric push rod is a new type of linear actuator mainly composed of a motor, a push rod and a control device. It can achieve long-distance control and centralized control. . The electric push rod moves back and forth within a certain range of stroke. Generally, the standard stroke of the electric push rod is 100, 150, 200, 250, 300, 350, 400mm. Special strokes can also be designed and customized according to different application conditions. Electric push rods can be designed with different thrusts according to different application loads. Generally, the maximum thrust can reach 6000N, and the no-load operating speed is 4mm~35mm/s. The electric push rods are powered by 24V/12V DC permanent magnet motors. source, converting the rotational motion of the motor into linear reciprocating motion. Push a set of linkage mechanisms to complete the switching work of dampers, valves, gates, baffles, etc.
Using an electric push rod as an actuator can not only reduce the air source device and auxiliary equipment required for a pneumatic actuator, but also reduce the weight of the actuator. Pneumatic actuators require a certain amount of air pressure during the entire control operation. Although amplifiers with small consumption can be used, the air consumption is still huge over time. When using an electric push rod actuator, power is required when changing the control opening, and power is no longer available when the required opening is reached. Therefore, from the perspective of energy saving, electric push rod actuators have obvious energy-saving advantages over pneumatic actuators. It is suitable for remote control and is widely used in 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. It is now used by more and more departments to replace automatic devices such as mechanism hands, hydraulic valves, and deceleration transmission mechanisms.
Uses of electric push rods:
Electric sofas, electric booth lifting rods, industrial electric lifting systems, camera stands, projectors, wedding systems, electric turn-over beds, electric nursing beds, etc. .
