Problems solved by technology

In addition, due to the harsh working conditions of reciprocating pumps used in petroleum engineering, there are generally problems of short service life of wearing parts and low efficiency during normal operation.
[0003] The seals of booster water injection pumps are easily damaged, and the one-time pump stop accident accounts for about 90% of reciprocating booster water injection pumps. In addition, there are other vulnerable parts that have low efficiency during normal operation of the pump due to life problems.

Abstract

The invention discloses a water injection pump hydraulic system comprising a pump cylinder, a coupler connected with the pump cylinder, and a hydraulic cylinder connected with the coupler. The hydraulic cylinder is connected with a constant power variable pump, the constant power variable pump is connected with a metering pump and an oil filter. The water injection pump hydraulic system has the advantages that the water injection pump hydraulic system is high in pressure, big in flow, simple in structure, is efficient and energy saving, long in service life, adjustable in discharge capacity, easy to maintain and operate, simple in structure, accurate and reliable in reversion and capable of increasing pressure.

Description

technical field [0001] The invention relates to a water injection pump hydraulic system. Background technique [0002] The development of the petroleum industry has put forward higher requirements for reciprocating pumps. On the one hand, the pressure and power of the pump are getting higher and higher, while the manufacturing and maintenance costs should be low, and the volume and quality should not be too large. In addition, because the working conditions of reciprocating pumps used in petroleum engineering are very harsh, there are generally problems of short service life of wearing parts and low efficiency during normal operation. [0003] The seals of booster water injection pumps are easily damaged, and one-time pump shutdown accidents account for about 90% of reciprocating booster water injection pumps. In addition, there are other vulnerable parts that have low efficiency during normal operation of the pump due to life problems. [0004] Therefore, there is an urgen...
