Description

Integrated oil immersion type hydraulic power unit

Technical Field

The invention relates to the technical field of hydraulic power units, in particular to an integrated oil-immersed hydraulic power unit.

Background

A Hydraulic Power Unit (HPU) is used as an oil supply and is connected to a plurality of hydraulic rams through an external piping system to control the actuation of a plurality of sets of valves. The oil tank, the oil pump and the energy accumulator form an independent closed power oil source system. The stations may be equipped with a PLC control system that controls all internal hydraulic functions and generates signals for exchange with a control room (DCS). Control elements, such as hydraulic servo valves, are mounted directly on the hydraulic rams, through which high pressure oil is forced into the rams or from which it is discharged. Under the normal state, the oil pump supplies oil to the system, the rated pressure of the system is automatically kept, and the position keeping function of the valve at any position is realized by locking the control valve; under the working state, the hydraulic actuator is controlled by the electromagnetic valve, a system command signal enables the electromagnetic valve to act, the oil pressure and the energy release of the energy accumulator are controlled, the oil cylinder slide valve is further controlled, the valve is driven by the mechanical transmission mechanism, and quick closing, normal opening and closing and test control are implemented. The high-pressure oil cylinder can be fixed on the valve rod and also can be directly used as an actuating mechanism. Redundant hydraulic oil returns to the hydraulic oil station, so that the pipeline system can control a plurality of valves connected in parallel by using an oil inlet pipe and an oil return pipe;
