Description
Technical field: the utility model relates to oil field oil recovery oil well pump, specifically is a kind of tubing pump.
Background technique: the tubing pump of oil field oil recovery usefulness, standing valve can not artificially be controlled and open when maintenance, when operations such as inspection pump, sand washing, can not open the oil-water mixture that causes in the oil pipe because of it and be scattered in ground with the proposition of oil pipe, not only pollute ground environment, waste crude oil, and workman's operating environment is abominable.The valve ball of this class pump is to lean on to close from repeats bits, and owing to annular space between valve ball, the cover is less, valve ball, cover surface are stained with crude oil and paraffin, and it is slower to cause valve ball to reset, and causes leakage, and reduces pump efficiency; In addition, the bottom of this class oil well pump has only a standing valve, and when valve seat or valve ball were lined with the grains of sand, bottom valve produced and leaks, and oil well pump can't be worked when serious, can only solve by the mode of well-flushing or operation.
Summary of the invention: the purpose of this utility model is to provide a kind of efficient, environmental protection oil well pump at the problems referred to above.
The utility model purpose is to be achieved by following technical proposals: efficient, environmental protection oil well pump is made of pipe joint, travelling valve, pump barrel, plunger, standing valve, valve cover, on travelling valve ball, standing valve ball Returnning spring is installed respectively; Spirally-guided slideway elevator mechanism is installed in the pump barrel bottom, and spirally-guided slideway elevator mechanism is connected with the standing valve cover, controls the standing valve ball with spirally-guided slideway elevator mechanism; Two standing valves are set below spirally-guided slideway elevator mechanism; Described spirally-guided slideway elevator mechanism comprises valve body, control spring, connecting leg, guiding lateral pin, and there is the spirally-guided slideway valve body intermediate portion, and control spring is built between pressure cap and the limited ring at valve body; Connecting leg combines interference fit with the guiding lateral pin; Pressure cap and connecting leg radially connecting part are equipped with ball, slide in the spirally-guided slideway in the two ends of guiding lateral pin.
The utility model is to utilize Returnning spring to drive valve ball fast, in time reset, and valve ball is closely contacted with ball seat, and therebetween oil, wax, sand is squeezed away, and valve is in time closed; Set up a standing valve at the oil well pump base, reduce the leak-down rate of standing valve; Utilize spirally-guided slideway elevator mechanism to control standing valve, by opening or closing of the sliding position control standing valve of guiding lateral pin in guide slide.
The good effect that the utlity model has: the be scattered problem of ground pollution ground environment of the oil-water mixture when the utility model has solved underground work in the oil pipe; Improve pump efficiency, reduce the leak-down rate of oil well pump; Prolong pump detection period, save operating cost.
