Performance test device and test method for seawater hydraulic motor under deep-sea high-back-pressure environment

Abstract

The invention discloses a performance test device and a performance test method for a seawater hydraulic motor under a deep-sea high-back-pressure environment. The performance test device mainly comprises a seawater hydraulic motor test system, a monitoring control system, a deep-sea simulation cabin, a pressure loading system and a circulating water cooling system, wherein the deep-sea simulation cabin provides back pressure required to bear while working under different water-depth environments for performance test of the tested seawater hydraulic motor by virtue of the pressure loading system; test load of the tested seawater hydraulic motor is freely regulated by virtue of a high-pressure flow control valve mounted in the circulating water cooling pipeline; and the circulating water cooling pipeline can effectively avoid rising the water temperature in the cabin due to heat generated by the seawater hydraulic motor operated under load, the motor and the like. The method can simulate the back pressure environment at a set ocean depth and can realize performance test for the seawater hydraulic motor, is simple to operate, easy to realize, not only overcomes the technical difficulty of lowering the seawater hydraulic motor into great-depth deep sea, but also can accurately obtain performance parameters of the seawater hydraulic motor.

Description

technical field [0001] The invention relates to a performance test device and test method of a seawater hydraulic motor in a deep sea high back pressure environment, which is suitable for the development of a sea water hydraulic motor, belongs to the field of marine technology, and is especially suitable for performance testing of a sea water hydraulic motor in a deep sea high back pressure environment. technical background [0002] Ocean development is an important field that various countries are competing for development. Whether it is underwater salvage, marine resource exploration, marine construction or marine defense projects, efficient underwater operation tools are needed. [0003] Traditional hydraulic pressure uses mineral hydraulic oil as the working medium, so there are some insurmountable disadvantages such as leakage pollution, and the system must be a closed circulation system with oil source. Seawater hydraulic transmission technology has irreplaceable advan...
