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.
In the process of production, when traveling valve and standing
valve in well tubing pump 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
