Mechanical anchor rod pump with thin wall and heavy wall can be withstand higher oil well temperatuer than the cup type. There are two series: RH and RW. This kind of rod pump is also equipped with a support joint, support joint connected on the tubing string, and it is together with the tubing string down to the bottom. Plunger assembly is connected on the rod string and together with the whole pump down to support joint position, pump is fixed within the support joint by external force, plunger assembly is together with the sucker rod string up and down reciprocating movement to achieve pumping work. If the pump appeared quality problem,it need not to put out of the tubing string, only through rod string together put out of the whole pump, operation is simple. RH series is convenient than the RW series when transportation.
