ED-80 ELECTRO HYDRAULIC AND 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 produced by mechanically compressing a load spring (with a load spring in a pusher or brake) by means of a lever.

3. When the power is cut off, the impeller stops rotating, and the piston drops rapidly under the action of the load spring 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.
