Oil -well pump scale control abrasionproof helps takes out ware

The utility model provides a scale control helps takes out the ware device, its difference lies in helping inlet port (4) the end and/or one nonrust steel pipe (3) of oil outlet (8) end installation of taking out ware (7), sacrificial anode (1) and high strength magnet (2) is equipped with in nonrust steel pipe (3), sacrificial anode (1) and high strength magnet (2) is put together according to the designing requirement, therefore scale control, the wax control, eccentric wear prevention, prevent leaking, increase oil pumping pump barrel negative pressure, take out in order to reach to help, the increase petroleum production, the extension oil -well pump life -span, thereby reduce the well workover frequency, the production efficiency is greatly increased, oil recovery trade in specially adapted oil field is used.
