Alloy Steel Plunger Thick Wall Barrel Well Pump Tubing
Alloy steel plunger thick wall barrel well pump tubing description:
The pump barrel assembly of the well tubing pump connected on the tubing string,and with its down to the bottom of the well.Plunger assembly connected on the sucker rod string and with it down to the pump barrel position in the well,then with it do up and down reciprocating motion, so as to realize the production process.
The inner surface of the well tubing pump barrel is processed with carbonization quench and chrome plating technology and the plunger surface is processed with thermal metal spraying technology. The pump meets the requirement of long stroke. high speed and deep producing and has the advantages of high pumping efficiency. large displacement ,wear and corrosion resistance,long operation and easy repairing.
In the process of production, when traveling valve and standing valve appear problems,we can pull the traveling valve and standing valve out the well through the sucker rod string, plungerand the puller ,instead of pull the whole pump and tubing string out of the well, reduce the labor intensity of operation, reduce the operation cost.
