What is the working principle of electric hydraulic pusher

The working principle of electric hydraulic pusher:
The electric hydraulic pusher is composed of two parts, the driving motor and the body (centrifugal pump), and the body part is composed of a cover, a cylinder, a piston, an impeller and a rotor.
When energized, the motor shaft and the impeller on the rotating shaft rotate, and pressure is generated in the piston. Under the influence of this pressure, the oil is sucked from the upper part of the piston to the lower part of the piston, forcing the piston and the push rod and beam fixed on it to move quickly. rise. Mechanical movement occurs by mechanically compressing a load spring (a pusher or brake with a load spring) by a lever.
When the power is turned off, the impeller stops rotating, and the piston is rapidly lowered under the effect of the load spring force and its own gravity, forcing the oil to flow into the upper part of the piston from the beginning.
Electric hydraulic pushers are often used in cooperation with brake frames, and are widely used in the braking of various transmission equipment.

Features of electro-hydraulic brakes:
With the continuous use of various electrical equipment in life, it has brought a lot of convenience to everyone's life, especially for some machinery and equipment equipped with drive and control equipment, which is not only widely used, but also in the process of use. Very convenient. Among them, the electric hydraulic pusher is a kind of drive control equipment that integrates the motor, the centrifugal pump and the oil cylinder with a very compact layout and is widely used. The main features of the electric hydraulic pusher are as follows:
1. The electro-hydraulic thruster has a simple structure and a relatively small volume, which will reduce the occupied area of ​​the thruster, so it has many fields and occupations and is flexible to use.
2. Electric hydraulic pushers are usually

Conditions of use of electric hydraulic thrusters
1. Ambient air temperature: -25℃～+50℃.
2. There should be no flammable, explosive and corrosive gases in the surrounding working environment, and the relative humidity of the air should not be greater than 90%.
3. The power supply is three-phase AC 380V 50Hz, and the voltage fluctuation should not exceed ±10% of the rated value.
4. The altitude of the place of use shall not exceed 2000m.
5. Applicable working system: continuous working system (S1) and intermittent cycle working system Installation and adjustment of brakes

When the electro-hydraulic brake is energized, the motor drives the transmission shaft and the impeller on the rotating shaft to rotate, and pressure is generated in the piston. Under the influence of this pressure, the oil is sucked from the upper part of Bendix slack adjuster the piston to the lower part of the piston, forcing the piston and the push rod fixed on it. The beam rises quickly. Mechanical movement is produced by mechanically compressing a load spring (a pusher or brake with a load spring) by means of a lever.

When the power is cut off, the impeller stops rotating, and the piston descends rapidly under the action of the load spring force and its own gravity, forcing the oil to flow back into the upper part of the piston, and at this time, it is still restored to its original position through the lever mechanism. Electric hydraulic pushers are often used in conjunction with brake frames, and are widely used in the braking of various transmissions.
Features of electro-hydraulic brakes:
With the continuous use of various electrical equipment in life, it has brought a lot of convenience to everyone's life, especially with regard to - some machines and equipment equipped with drive control equipment are not only widely used, but also in the process of use. is also very convenient. Among them, the electro-hydraulic thruster is a kind of drive and control equipment that integrates a motor, a centrifugal pump and an oil cylinder with a very compact layout and is widely used. The main features of the electro-hydraulic thruster are as follows:
1. The electro-hydraulic thruster has a simple structure and a relatively small volume, which will reduce the occupied area of ​​the thruster, so it has many fields and occupations and is flexible in use.
2. Electric hydraulic pushers are usually made of aluminum alloy materials, so they have excellent anti-corrosion performance characteristics, and also have excellent underwater impact force, which is more convenient, convenient and agile in use.
