Abstract

The invention relates to a variable-stroke ratio-regulated reciprocating pump and mainly solves the problem that the liquid flow of the traditional injection pump cannot be regulated. The ratio-regulated reciprocating pump is characterized in that a pump body (1) is provided with more than two plungers (2) which are in parallel and independent from each other, a plunger clutch mechanism for ensuring that a cross spider (3) is clutched with the plunger (2) when the plunger (2) absorbs the liquid is arranged at one end of the plunger (2), the cross spider (3) is connected with a crankshaft through a connected rod and a plunger travel limiting mechanism for limiting the liquid absorbing stroke is arranged at the other end of the plunger (2). The variable-stroke ratio-regulated reciprocating pump has the characteristic that the liquid flow can be adjusted.

Description

Technical field: [0001] The invention relates to a pump required for injecting ternary agent in the field of oil recovery, in particular to a variable stroke proportional adjustment reciprocating pump. Background technique: [0002] In the field of oil recovery, in order to improve the recovery rate, the three-element oil injection technology will be popularized in a large area. The currently selected three-element injection equipment is to connect three volume-adjusting injection pumps with different displacements in series to respectively inject polymer, alkali, and Surfactants are exported in proportion, and then mixed and injected into the ground. The liquid flow rate of this kind of pump cannot be adjusted, thus causing the problems of high cost, difficult equipment management and high equipment maintenance cost, which is not conducive to popularization and application. Invention content: [0003] In order to solve the problem that the liquid flow rate of the existin...
