High Precision Well Pump Tubing With Chromium Molybdenum Alloy Steel Material
Product description
operating principle of tubing pumps: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.
