Working principle and characteristics of long plunger pump

Long plunger pump works: Long plunger plunger pump with long plunger, short pump and pump sanding, lateral into the oil structure. Mainly by: long plunger, short pump cylinder, double-pass connector, grit outer cylinder, into and out of oil valves, hydraulically connected retaining ring and other components. The sand control card works with the help of sandblasting ring and the combined effect of liquid leakage to prevent the sand into the gap between the plunger and the pump cylinder seal, thereby eliminating the sand card; when the well stop pumping, sinking the sand along the sink Sink ring sink into the pump under the pipe, to prevent the sand buried. Features: sand control card, sand buried, anti-sand, corrosion-resistant long life to reduce partial tube wear and tear easy maintenance
