The sand control plunger assembly is composed of upper and lower sand scrapers, plungers and swimming valve covers.
1. The spray welding process is used to spray and weld a layer of nickel-based alloy powder on the surface of the plunger and the upper and lower sand scrapers, which has good anti-corrosion and wear resistance properties;
2. Unique structure, wide use, simple and convenient to use, operate and maintain;
3. Compared with the ordinary metal spray welding plunger assembly, the sand control plunger assembly can temporarily gather sand in the sand scraping groove between the plunger and the pump barrel, preventing sand particles from entering between the plunger and the pump barrel. So as to avoid scratches on the two surfaces, improve the pump efficiency, and avoid the pumping pump and sand burial;
4. Automatically flush the sand to prevent the sand from sticking to the plunger, which improves the pump efficiency and prolongs the production cycle of the sand-producing oil well.
