Abstract

The invention relates to an automatic pressurized reciprocating pump controlled by mechanical valve, comprising a group of pressurized reciprocating device at least. Said pressurized reciprocating device is characterized in that two-pole or multi-pole cylinder is connected in the same axis, automatic controlling switch valve units are set on two ends of cylinder respectively, one end of contact tip in automatic controlling switch valve units and cylinder piston are set in the inner cavity of cylinder. Each group of pressurized reciprocating device is connected in parallel. The invention improves not only pressurized grade but also discharge grade. It is provided with low cost, good sealing, good safety and stability so on.

Description

technical field [0001] The invention relates to a reciprocating pump whose piston can continuously reciprocate, in particular to a mechanical valve-controlled automatic booster reciprocating pump. Background technique [0002] At present, there are precedents at home and abroad for using compressed air or liquid as power to increase the mechanical device for conveying fluid medium through a cylinder or liquid cylinder with two poles connected in series. However, under different usage conditions, the medium to be pressurized and conveyed has a different allowable range of pressure difference at the inlet. During the pressurized conveying process, when the pressure at the inlet exceeds the allowable range, insufficient material supply or displacement Insufficient and other abnormal phenomena, resulting in insufficient displacement when selecting booster equipment specifications, or excessively low front-end pressure due to excessive suction, thus affecting the normal operation...
