A compact multi-channel hydraulic power unit

Abstract

The invention discloses a compact multipath hydraulic power unit, and belongs to the technical field of hydraulic power devices. The compact multipath hydraulic power unit comprises an oil tank, a main valve block, a main electric pump, a standby electric pump, a first manual pump, a second manual pump and a wall. The oil tank and the main electric pump are arranged at the upper end and the lower end of the main valve block correspondingly. The first manual pump and the main valve block are fixedly connected in parallel. The standby electric pump is arranged below the first manual pump. The main valve block and the first manual pump are fixedly arranged on one side of the wall. The second manual pump is fixedly arranged on the other side of the wall and corresponds to the mounting position of the first manual pump. The first manual pump communicates with the second manual pump through wall penetrating oil pipes penetrating the wall. A set of output connectors is arranged on the side face of the main valve block. The compact multipath hydraulic power unit has the beneficial effects that design is reasonable, and the structure is compact; the main electric pump, the standby electric pump, the first manual pump and the second manual pump are integrated, and therefore opening of a watertight door can be controlled in multiple manners; and high reliability is achieved, the integration degree is high, and the size is small.

Description

technical field [0001] The invention relates to the technical field of hydraulic power devices, in particular to a compact multi-channel hydraulic power unit. Background technique [0002] The hydraulic power unit is the heart of the hydraulic power system. Multi Power Unit (MPU for short) is mainly used in sliding watertight doors of ships, and is used in conjunction with hydraulic cylinders to provide power for the opening and closing of the doors. The traditional watertight door hydraulic drive system includes: pump station, accumulator and other components, which are bulky and take up a lot of space; in addition, there is energy loss in the accumulator, and the pump station is required to recharge the accumulator at regular intervals , resulting in a great waste of resources, and also affects the reliability of the system, and the later maintenance cost is high. In addition, in the traditional hydraulic drive system, the pipelines used for system connection are relativ...

Problems solved by technology

The traditional watertight door hydraulic drive system includes: pump station, accumulator and other components, which are bulky and take up a lot of space; in addition, there is energy loss in the accumulator, and the pump station is required to recharge the accumulator at regular intervals , resulting in a great waste of resources, and also affects the reliability of the system, and the later maintenance cost is high

In addition, in the traditional hydraulic drive system, the pipelines used for system connection are relatively complicated, which increases the risk of system failure and affects the overall appearance of the watertight door system; at the same time, the traditional watertight door hydraulic power unit has a single function. When the energy of the accumulator is exhausted, there is no good emergency plan, which wastes a lot of time and has poor flexibility; the traditional hydraulic power system has a relatively simple structure and layout and poor flexibility
