Hydraulic piston pump is developed rapidly in recent years

This paper introduces the structural characteristics and working principle of a new type of hydraulic piston pump, diesel pump manufacturers and the performance parameters of this kind of pump is also introduced. Production practice of the type hydraulic piston pump by the Shenyang oil recovery of high pour point oil, compared with using conventional hydraulic piston pump cycle, period of changing the pump is extended from 1 months to 9 months, can save the pump inspection costs more than 1 yuan.
Hydraulic piston pump is developed rapidly in recent years a rodless oil pumping equipment.It depends on the hydraulic transmission energy, pumping crude oil to the ground from the well.It can rely on the hydraulic up, adapt to the high wax oil, high pour point oil in deep well, deep well and complex well conditions. The Shenyang oil field has since the end of 1986 formally put into development, mechanical fuel level gauge ,in order to meet the need of high pour point oil mining, hydraulic piston pump as a recovery of high pour point oil reservoir.
