pump and pump parts

operating principle of tubing pump

The pump barrel assembly directly fixed on a tubing string. the plunger assembly connected on the sucker rod string ,and with the up and down reciprocating motion, so as to realize the production process. Its advantage lies in: in the process of oil production, when the traveling valve and fixed valve side problems arise,valve side can be proposed by the sucker rod, piston and extractor , don’t put the whole pump and tubing string out of the well, reduce the work intensity and the operation cost.

about tubing pumps:

 Tubing pump mainly consists of working barrel,bushing,fixed valve,piston,traveling valve,coupling.Conventional tubing pump is liner plunger pump,metal plunger pump.The diameter specifications are 150,175,225,etc.

advantages

Simple structure,under the same condition,with the permission of the barrel diameter larger than the rod pump.In addition,the piston surface has ring groove,it can prevent sand abrasion the piston surface and liner surface.
