Abstract

The invention discloses a reciprocating pump variable in supercharge ratio. The reciprocating pump comprises a reversing valve, a left control valve, a right control valve, a pump housing provided with an axial pore channel, a left cylinder body provided with a left large plunger piston cavity and a left small plunger piston cavity and a right cylinder body provided with a right large plunger piston cavity and a right small plunger piston cavity. The left cylinder body and the right cylinder body are respectively connected to the left end and the right end of the axial pore channel of the pumphousing, a piston is slidingly connected in the axial pore channel of the pump housing, the left end of the piston is provided with a left large plunger piston body and a left small plunger piston body, the right end of the piston is provided with a right large plunger piston body and a right small plunger piston body, a left piston cavity is formed between the left end of the piston and the leftcylinder body and a right piston cavity is formed between the right end of the piston and the right cylinder body in the axial pore channel of the pump housing. The reciprocating pump is compact in structure, low in cost and variable in supercharge ratio.

Description

technical field [0001] The invention relates to the technical field of booster pumps, in particular to a reciprocating pump with variable booster ratio. Background technique [0002] The reciprocating booster pump is an important hydraulic component widely used in diamond six-sided top presses. Through the reciprocating booster pump, the outlet pressure is gradually boosted to about 100MPa to meet the technological requirements of diamond synthesis. The diamond synthesis process requires Below 60MPa, pressurization should be carried out at the fastest speed. At this time, the demand for boost flow is relatively large, while above 60Mpa, it is mainly the pressure-holding stage, and the requirement for boost flow is relatively small. The reciprocating booster pump needs a smaller boosting ratio to achieve a larger boosting flow, and a larger boosting ratio to achieve a higher pressure. Therefore, it is used in the existing six-sided top press In order to meet the requirements...
