Ed 30/5 Electro-hydraulic Thrusters

A brake is a brake, a mechanical part that stops or slows down moving parts in a machine.

Commonly known as brakes, brakes. The brake is mainly composed of frame, brake parts and operating device. Some brakes are also equipped with an automatic adjustment device for the clearance of the brake parts.

In order to reduce the braking torque and structural size, the brake is usually installed on the high-speed shaft of the equipment, but for large-scale equipment with high safety requirements (such as mine hoists, elevators, etc.), it should be installed on the low-speed shaft close to the working part of the equipment. superior.

Principle of Electrohydraulic thruster

1. The working principle of the electro-hydraulic propeller. The electro-hydraulic propeller 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.
2. When energized, the motor drives the transmission shaft and the impeller on the rotating shaft to rotate, generating pressure 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. rise rapidly. Mechanical movement is generated by mechanically compressing the load bomb (the pusher or brake has a load bomb) by means of a lever.
3. When the power is cut off, the impeller stops rotating, and the piston quickly descends under the action of negative elastic force and its own gravity, forcing the oil to flow into the upper part of the piston again, and at this time it is still restored to its original position through the lever mechanism.
