Piston Vacuum Pump in Oilfield Production

The piston vacuum pump injects high-pressure power fluid into the downhole pump through the ground pump, and controls the up and down motion of the piston at the power end through the hydraulic sliding valve, thus driving the piston of the pumping pump to move back and forth and lifting the downhole liquid to the ground. Because it adopts hydraulic direct transmission and belongs to rodless pump series, which can effectively avoid elastic loss, the piston vacuum pump has a small stroke loss, a volume efficiency of 85% and a system efficiency of more than 35%.


The working principle of piston vacuum pump is that the connecting rod is mounted together by bearing and eccentric pressure, and the eccentric wheel is locked on the motor shaft. Because of the rotation of the rotating shaft, the connecting rod moves to and fro, thus realizing the process of air absorption, compression and discharge.


Piston vacuum pump can be widely used in medical equipment, automotive industry, automatic control, printing machinery, packaging machinery, food preservation, aquaculture, water purification treatment, analytical instruments, beauty and health care, advertising production, equipment maintenance, biopharmaceuticals, communications electronics, petrochemical industry, environmental testing system, plateau oxygen production and other fields; it is the need of the industrialized society to purify and ring. Vacuum holder is a good choice.


The main advantages of piston vacuum pump in oil field production are high displacement and maximum lift under the same casing size; pump efficiency as high as 85%; hydraulic starting and unloading pump without workover operation; adaptability to various complex surrounding geographic environment, small occupation area, etc.
