A full-condition test equipment and test bench for a full-sea depth buoyancy regulation system

Abstract

The invention discloses a full-sea deep buoyancy adjustment system full-working-condition test equipment and a test bench, which are used for performance testing of the full-sea deep buoyancy control system in a simulated deep-sea environment, and belong to the field of full-work-condition testing of deep-sea equipment. In the present invention, the motor, seawater pump, integrated control valve group, and hydraulic source are placed in the high-pressure chamber of the host system of the full-sea deep environment simulation test bench, and the power supply and control of the motor and hydraulic source in the ultra-high pressure environment are realized through watertight connectors. The ballast water tank, power supply unit and control unit are placed outside the hyperbaric chamber, and the ballast water tank is connected to the valve group to be tested in the hyperbaric chamber, so that it is more convenient and comprehensive to test the performance of the buoyancy adjustment system from the outside , no supporting equipment such as ballast tanks and batteries that can withstand ultra-high external pressure, greatly saving test costs, reducing test risks, and more comprehensive performance testing. The test bench can simulate 11,000-meter deep-sea ultra-high pressure, strong corrosion and ultra-low temperature environment .

Description

technical field [0001] The invention belongs to the field of full-working-condition testing of deep-sea equipment, and relates to full-working-condition test equipment and a test bench for a full-sea deep buoyancy regulation system, and more specifically, to a full-working-condition test method for a full-sea deep buoyancy regulation system. It can be used for the performance test of the deep sea buoyancy adjustment system in the environment of ultra-high external pressure. Background technique [0002] Marine equipment, especially deep-sea equipment, is an important tool for human beings to carry out marine resource exploration, scientific investigation, development operations, military detection and combat platforms. In the process of diving and surfacing of deep-sea equipment, a buoyancy adjustment system is often required to adjust itself of buoyancy. As the depth of the ocean increases, the external pressure on the buoyancy adjustment system is getting higher and highe...

AI Technical Summary

Problems solved by technology

[0003] As the ambient pressure is as high as 110MPa, some testing instruments cannot withstand such a high external pressure, so it is impossible to fully test the performance of the full-sea deep buoyancy adjustment system

In addition, the current full-sea buoyancy adjustment system's full-condition test method is to place both the power supply and the ballast water tank in an ultra-high pressure environment, which cannot fully test its performance, and the test cost is high and the risk is relatively high

[0004] In order to carry out full-sea deep buoyancy adjustment system full-condition tests, it is necessary to use a full-sea deep environment simulation test bench to simulate the deep-sea environment, but the current test bench can only simulate the deep-sea ultra-high pressure environment, but cannot simulate deep-sea strong corrosion and ultra-low temperature environment, and hydraulic oil is used as the transmission medium, there will be leakage into the environment during use and the oil needs to be recycled, resulting in high cost and serious pollution of environmental pollution
