Performance testing device and method for deep-sea power source

Abstract

The invention discloses a deep sea hydraulic pump testing device and method. The device comprises a deep sea simulation cabin, and the deep sea simulation cabin is connected with a hydraulic pump pressurizing device, a hydraulic pump and overflow valve loading device and a circulating water cooler. Deep sea complex environments are simulated by means of a pressure-resistant cabin, and required pressure of 0-50 MPa is provided for the pressure-resistant cabin through the hydraulic pump pressurizing device. The hydraulic pump and overflow valve loading device is adopted in order to avoid sharp temperature increase caused when a lot of heat generated by direct loading of an overflow valve cannot be quickly dissipated, heat is directly dissipated in atmosphere, and small part of the heat is cooled through the circulating water cooler. The deep sea power source performance testing device can simulate deep sea environments with different environment pressures and different environment temperatures, has the advantages of being high in simulation precision and slightly influenced by working condition changes, and can conduct various performance tests of a deep sea hydraulic pump under simulating deep sea working conditions in the atmospheric working condition.

Description

technical field [0001] The invention belongs to the field of deep-sea hydraulic transmission, and in particular relates to a performance testing device and method of a deep-sea power source. Background technique [0002] At present, all countries in the world have entered a period of large-scale, all-round and multi-field development and utilization of marine resources, and my country has a vast ocean area and rich marine resources. And the only way to realize the world's ocean power. For the hydraulic control system of these underwater equipment, the performance of the hydraulic pump will be affected in the complex marine environment where the seawater pressure changes greatly and the temperature difference changes significantly. Therefore, it is very important to perform a performance test on the hydraulic pump in the deep sea environment. , but it is too costly, too difficult to operate, and not feasible to perform performance tests on hydraulic pumps in the actual deep-s...

Problems solved by technology

[0004] These two schemes have their own limitations: in the deep-sea environment at 4000-6000m, the pressure is about 50MPa and the temperature is 0-10℃. In order to simulate the complex deep-sea environment more accurately, the pressure and temperature elements must be considered. Different water depths, pressure and temperature are changing

However, the above-mentioned first method does not fully consider the temperature factor, and the temperature has a great influence on the viscosity of the hydraulic oil. Therefore, it is not accurate enough to use the first method to simulate the deep-sea hydraulic environment to test the pump; the second method is not accurate enough for temperature changes. And the countermeasures taken are not thoughtful enough.
