A deep-sea low-noise variable pump

Abstract

The invention relates to a deep-sea low-noise variable displacement pump, which includes a pump body, the pump body includes a cylinder body arranged at a distance, a first sealing plate extending from the cylinder body to the distance, and is located between the cylinder body and the first sealing plate The plug between the plugs and the plunger seat sealingly connected between the first closed plates on both sides, the cylinder body, the first closed plate, the plug and the plunger seat form an oil chamber for containing oil; the cylinder body A plunger hole is set on the inner end surface, and the plunger hole is connected with a low-pressure inlet, and the outer end surface of the cylinder body is provided with a high-pressure outlet; The slot is equipped with a rotating coil, and a thrust coil is set on the plunger seat; the purpose of changing the displacement of the plunger pump can be achieved by controlling the movement speed of the permanent magnet plunger, and the displacement of the plunger pump can also be changed by adjusting the distance between the plunger hole and the plunger. The stroke of a single movement of the plunger to change the displacement of the plunger pump.

Description

technical field [0001] The invention relates to the technical field of underwater hydraulics, in particular to a deep-sea low-noise variable displacement pump. Background technique [0002] The development of deep-sea resources has received more and more attention, and the development equipment has become more and more diverse. The hydraulic system has the advantages of strong carrying capacity, high power density, and convenient speed regulation, and is widely used in the development of deep sea resources. However, with the entry of human beings, the noise of various machinery and equipment has a great impact on the life of marine life. [0003] Common pump structures in hydraulic systems include gear pumps, plunger pumps, vane pumps, and screw pumps. The gear pump mainly has the advantages of simple structure, good processing technology, small size, wear resistance, strong anti-pollution ability, etc., but it also has the disadvantages of low volumetric efficiency at low...

AI Technical Summary

Problems solved by technology

Gear pumps mainly have the advantages of simple structure, good processing technology, small size, wear resistance, strong anti-pollution ability, etc., but there are also disadvantages such as low volumetric efficiency at low speeds, generally high operating speed and high noise

[0004] The screw pump mainly has the advantages of small pressure pulsation, low noise, high volumetric efficiency, and strong anti-pollution ability, but the screw pump has disadvantages such as difficult processing and low operating pressure.

[0005] The vane pump has the advantages of uniform flow, stable movement, low noise, and small volume, but the vane pump is prone to cause the vane to be stuck, and has high requirements for the cleanliness of the oil

[0006] The plunger pump has various structural forms, and has the advantages of high working pressure, high efficiency, and convenient variable variables, but because of its large flow pulsation, it will emit a lot of noise during operation
