Description
The steering gear is mainly composed of a rotary vane rudder motor, a power pump group, a reserve oil tank …
1. rotary vane rudder motor-the rotor in the motor cavity receives the pressure oil from the power pump unit, drives the rotor and transmits the torque to the rudder stock for the purpose of steering.
2.power pump group-It is assembled from hydraulic pump, solenoid valve, control valve, etc. It is very compact and the pump set is controlled by the electric control system.
3.reserve oil tank-It is an accessory on the hydraulic system of the steering gear, which is required for oil supply and refueling of the hydraulic system.
