Anti-sand plunger assembly

The sand control plunger assembly is a special form of the metal spray welding plunger assembly. The sand control plunger assembly not only provides all the features of the conventional metal spray welding plunger assembly, but also has the functions of scraping sand and sand discharging to overcome The shortcomings and deficiencies of the conventional plunger assembly.

Structure:

The sand control plunger assembly is composed of an upper and a lower scraper, a plunger and a swimming valve cover.

Features:

1. Spray-weld a layer of nickel-based alloy powder on the surface of the plunger and the upper and lower scraper by spray welding process, which has good anti-corrosion and wear resistance;

2. Unique structure, wide application, easy to use, operate and maintain;

3. Compared with the ordinary metal spray welding plunger assembly, the sand control plunger assembly can temporarily collect the sand in the sanding groove between the plunger and the pump barrel, preventing the sand particles from entering between the plunger and the pump barrel. So as to avoid scratching the surface of both, improve the pump efficiency, avoid the pump pump and sand burying;

4. Automatically flush the sand particles to prevent the sand card plunger, improve the pump efficiency and prolong the production cycle of the sand oil well.
