Accumulator-driven hydraulic motor and rotary pump underwater weapon launch power plant

Abstract

The underwater weapon launching power device of the present invention is an accumulator-driven hydraulic motor and a rotary pump. Before the underwater weapon is launched, the motor is started, and under the action of the hydraulic pump, the hydraulic oil in the oil tank passes through the hydraulic pump, the first one-way valve , the spherical stop valve flows into the gas accumulator; the pressure gauge switch is connected with the pressure gauge, and the other end of the pressure gauge switch is connected with the outlet of the first one-way valve; when the reading of the pressure gauge reaches the preset value, it is closed Electric motor; when launching an underwater weapon, the electro-hydraulic reversing valve is energized to act, and the high-pressure oil in the gas accumulator enters the high-pressure port of the hydraulic motor through the spherical stop valve and the electro-hydraulic reversing valve, driving the hydraulic motor and driving it to rotate The water pump rotates at an accelerated speed, the inlet of the rotary water pump is connected with the seawater, the outlet of the rotary water pump is connected with the launch tube of the water cabin, and the large flow of seawater is output from the rotary water pump to the launch tube of the water cabin, and the underwater weapon is pushed out of the tube. The underwater weapon launching power device of the invention has low noise, low manufacturing cost and can avoid cabin pressurization.

Description

technical field The invention relates to the technical field of submarine torpedo underwater launching, in particular to a water pressure balanced underwater weapon launching power device in which a gas accumulator drives a hydraulic motor and a rotary pump. Background technique In foreign countries, the prime mover of the rotary pump water pressure balanced torpedo launcher is an air turbine, so it is referred to as the turbo pump launcher. In the United States and the United Kingdom, the turbo pump launcher has become the installed equipment of their navies, and it is the most advanced submarine weapon launcher in active service. Both the US "Sea Wolf" class nuclear submarine and the British "Avantgarde" class nuclear submarine use the launcher. Russia has completed the research on the principle prototype of the launcher. my country is developing it. However, the use of air turbines as actuators has some disadvantages: firstly, using compressed air as the energy source ...

AI Technical Summary

Problems solved by technology

However, the use of air turbines as actuators has some disadvantages: first, the use of compressed air as the energy source inevitably produces exhaust noise in the cabin and causes cabin pressurization (especially the bow cabin); secondly, the air turbine passes through the reducer. Connected with the rotary water pump, not only the inertia is large, but also noise will be generated when rotating at high speed; moreover, the launching device is expensive

The hydraulic accumulator torpedo launching devices developed by the United States, German HDW Company and French DCN Company all use hydraulic cylinders as actuators, which are relatively bulky and do not have the advantages of light weight and small size of turbo pump launching devices.
