Abstract

The invention relates to a performance testing device and method for seawater hydraulic pump in deep sea high back pressure environment. The performance testing device mainly comprises a deep sea stimulation cabin, a pressurizing system, a circulating water cooling pipeline, and a monitoring and controlling system; the deep sea stimulation cabin provides back pressures to be borne in environments at different water depths for the performance test of the seawater hydraulic pump through the pressurizing system; stimulation load of the seawater hydraulic pump is freely adjusted by a high-pressure flow control valve which is mounted in the circulating water cooling pipeline; the circulating water cooling pipeline can prevent temperature rise of water in the cabin caused by transformation of the hydraulic energy generated by the working seawater hydraulic pump to the heat energy after the high-pressure flow control valve is uploaded; the monitoring and controlling system can control test working conditions of the seawater hydraulic pump and acquire test parameters such as temperature, pressure and flow. The testing device can stimulate the back pressure environment at an appointed sea depth and realize performance test on the seawater hydraulic pump.

Description

technical field [0001] The invention belongs to the technical field of water hydraulic transmission, and relates to a test technology of a hydraulic pump using pure water as a working medium in a deep sea high back pressure environment, in particular to a performance testing device and method for a seawater hydraulic pump in a deep sea high back pressure environment. Background technique [0002] Seawater hydraulic transmission technology has unique application advantages in the field of marine underwater engineering technology such as marine resource exploration, underwater robots, and submersible buoyancy adjustment. In some occasions, it is even the only choice. This is because the traditional hydraulic system using mineral hydraulic oil as the working medium, because the hydraulic oil is incompatible with seawater, the hydraulic system must be designed as a closed cycle structure and equipped with a pressure compensator. As the depth of the ocean increases, the The back ...
