AI Technical Summary

Technical Problem

When existing underwater hydraulic systems meet complex submarine operations, it is difficult to achieve efficient, economical and reliable power source design, especially under the diverse needs of system pressure, flow and power.

Method used

An underwater multi-mode hydraulic power source is designed. Through switching of the power source working mode, two gear pumps with different displacements and multiple solenoid switch valves are used to switch four working modes to ensure that each hydraulic actuator is reasonably supplied with oil.

Benefits of technology

It realizes the efficient and economical advantage of supplying oil according to the different needs of each actuator. At the same time, due to the simple mode switching, the system is highly reliable.

Abstract

According to the underwater multi-mode hydraulic power source provided by the invention, reasonable oil supply is performed on each hydraulic execution element by switching the working modes of the power source, and the underwater multi-mode hydraulic power source has the advantages of high efficiency and economy. The hydraulic power source comprises an oil tank, an underwater compensator, two gear pumps, a motor, a normally-closed electromagnetic switch valve, a normally-open electromagnetic switch valve A and a normally-open electromagnetic switch valve B, the displacements of the two gear pumps are different, namely a gear pump B and a gear pump A; the motor is connected with the gear pump B and the gear pump A through couplings, and when the motor works, the two gear pumps work coaxially and synchronously; an outlet of the gear pump A is communicated to an oil tank through a pipeline provided with a normally-open electromagnetic switch valve A, and an outlet of the gear pump B is communicated to the oil tank through a pipeline provided with a normally-open electromagnetic switch valve B; the outlet of the gear pump A1 is further communicated to the P1 port, and the outlet of the gear pump B is further communicated to the P2 port; and the P1 port and the P2 port which are used as output ports are communicated through a normally closed electromagnetic switch valve.
