Description

A kind of oil pumper by solenoid actuated

Technical field

This utility model is related to a kind of oil rig, and in particular to a kind of oil pumper by solenoid actuated.

Background technology

Oil pumper is a kind of machinery equipment for exploiting oil, is commonly called as " machine of kowtowing ", makes oil go out well by the method pressurizeed. When oil pumper upstroke, oil pipe elastic shrinkage is moved upwards, and driving mechanical block-relief oil production device is moved upwards, is clashed into sliding sleeve and is produced Vibration；Meanwhile, copper current only valve is closed, and reducing piston assembly closure oil is when oil pumper down stroke, and oil pipe elastic elongation is downward Motion, driving mechanical block-relief oil production device is moved downward, and is clashed into sliding sleeve and is produced vibration；Meanwhile, reversed check valve part is closed, reducing Piston assembly still blocks oil jacket ring shaped oil passage, makes reversed check valve lower zone form higher-pressure region, and this motion is again to stratum Interior oil flow channel produces a kind of reverse impulsive force.It is the conventional tradition oil pumping in oil field that common oil pumper is beam pumping unit Equipment, is generally directly dragged by ordinary ac asynchronous motor.Motor drive crank, its crank band is with machineries such as balances Part drives caput Equi Asini to move up and down, while driving downhole pump to fix the pumping of cycle, the oil of down-hole is sent To ground.But this frame for movement not only complex structure, the high cost for driving caput Equi Asini to move up and down, and easily abrasion uses the longevity Life is not long.

Utility model content

Technical problem to be solved in the utility model is in traditional oil pumper, to drive the machinery knot that caput Equi Asini moves up and down Structure not only complex structure, high cost, and service life of easily wearing and tearing is not long.Therefore the purpose of this utility model is to provide a kind of By the oil pumper of solenoid actuated, in solving traditional oil pumper, frame for movement that caput Equi Asini moves up and down not only structure is driven Complicated, high cost, and the problem that service life of easily wearing and tearing is not grown.
