What is Electric Pushing Rod: The Beginner’s Guide


The electric pushing rod is a new type of electric linear actuator.

The electric pushing rod is mainly composed of a motor, a metal pushing rod and a control device.

It can realize remote control and centralized control.

Learning more about what is electric pushing rod here, you will be an expert through this guide.

Let’s keep reading.

1.Electric Pushing Rod Brief Introduction

The electric pushing rods can be divided into two common models.

One is called the DTIA electric pushing rod.

The other is called the DTII electric pushing rod.

The difference between the two models electric pushing rods is the installation position of the motor.

The DTIA electric pushing rod’s motor is connected at the bottom of the pusher.

The DTII electric pushing rod’s motor is placed parallel to the pushing rod.

The electric pushing rod performs reciprocating motion within a certain range of stroke.

Generally, the standard stroke of the electric pushing rod is 200mm, 300mm, 400mm, 500mm, etc.

And the special strokes can also be designed and manufactured according to different application conditions.

Electric pushing rods can be designed with different thrusts according to different application loads.

Generally, the maximum thrust can reach 4000Kg, and the working speed is 42mm~50mm/s.

The electric pushing rod uses a 380V three-phase motor as the power source to convert the motor’s rotary motion into linear reciprocating motion.

2.Electric Pushing Rod Working Principle

After the motor is decelerated by the gear, it drives a pair of lead screw nuts.

The rotary motion of the motor is turned into a linear motion, and the forward and reverse rotation of the motor is used to complete the pushing rod action.

For example, complex actions such as rotation and shaking can be completed by various levers, rockers or linkages and other mechanisms.

By changing the length of the lever arm, the stroke can be increased or enlarged.

3.Electric Pushing Rod Application

Pushing a set of linkage mechanisms to complete the switching work of dampers, valves, gates, baffles, etc.

The use of electric pushing 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.

When the control is changed, power supply is required. When the required opening is reached, power supply is no longer needed.

Therefore, from the perspective of energy saving, the electric pushing rod actuators have obvious energy-saving advantages than pneumatic actuators.

The electric pushing rods are suitable for long-distance operation and are widely used for opening and closing, material loading and unloading, flow control of dampers, valves, gates and other institutions in electric power, chemical industry, metallurgy, mining, light industry, transportation, shipping and other fields.

It has been accepted by more and more industries to replace the automatic devices of manipulators, hydraulic control valves, and reduction transmission mechanisms.
