The pump barrel, the long plunger and the sand sinking of the pump, the long plunger sand-resistant oil well pump with side-intake structure is a widely used sand-proof oil well. Through the up and down stroke of the plunger, the liquid passes through a two-way joint and a two-stage fixed valve. It is continuously pumped to the ground, and at the same time, a part of the sand that cannot be carried by the tubing string is passed through the annulus of the pump barrel and the grit drum, and the double-way joint is sunk into the grit tail pipe.
1. A long plunger connected by a short plunger 1.2 meters or 1.5 meters long.
2. One-piece long plunger with integral spray welding, straightening and through-grinding.
1. The outer surface adopts spray welding remelting technology to recheck a layer of nickel-based alloy powder. This technology can ensure that the plunger has a long-term
It has the characteristics of corrosion resistance, wear resistance and dimensional stability.
2. The long plunger has high overall dimensional accuracy, good straightness and coaxiality, small flow resistance coefficient when in use, and smooth outer surface.
Easy to foul, no pump stuck.
