Metal spray welding long plunger
Short pump cylinder, long plunger and pump sinking sand, long plunger sand pump for side oil intake structure is a widely used sand control pump, through the plunger up and down stroke, liquid through the two-way joint, two-stage fixed The valve is continuously pumped to the ground, and a part of the tubing string can not be carried through the pump cylinder and the grit tube, and the double-pass joint sinks into the grit tube.
1. A long plunger connected by a short plunger of 1.2 meters or 1.5 meters.
2. Integrated long plunger with integral spray welding, straightening and grinding.
1. The outer surface adopts spray-welding remelting technology to review a layer of nickel-based alloy powder. This technology can ensure that the plunger is long-term.
It is resistant to corrosion, wear and dimensional stability.
2. The long plunger has high overall dimensional accuracy, good straightness and good coaxiality. The flow resistance coefficient is small when used, and the outer surface is smooth.
Easy to scale, no card pump.
