Abstract
The invention is an elastic seal valve oil pump, relating to an oil extraction lifter in oil field, where the oil pipe of the invention is internally equipped with pump tube, the pump tube is internally equipped with plug, the top end of the plug is connected with plug connecting piece though thread, sealing component is fastened on the outer surfaces of the pump tube and the plug through thread, the bottom end of the pump tube is connected with removable connecting piece through thread, the second fastener on the removable connecting piece is fastened on a connecting hoop at the lower part of the oil pipe, oil outlet valve is fastened on the pump tube through first fastener, oil inlet valve is fastened on the removable connecting piece through thread. And the invention can raise pump efficiency and make sealing more reliable, easy to operate and convenient to maintain, saving operating time and reducing workers' labor strength.
Description
Technical field
The present invention relates to a kind of lift device of oil field machinery oil.
Background technique
At present, most of pumping well all adopts conventional rigidity oil well pump, carries out rigid seal by valve ball, exists pump efficiency low, and it is bigger influenced by dead oil, dead wax, sand, mechanical admixture etc., and the operation of inspection (changing) pump need play oil outlet tube, and flow chart is loaded down with trivial details.
Summary of the invention
The objective of the invention is to have problems such as pump efficiency is low, flow chart is loaded down with trivial details, a kind of high pump efficiency is provided, is easy to the elastic-sealing-valve oil pump of operation for solving conventional tubing pump.The present invention is by oil pipe 1, plunger link 2, black box 3, pump barrel 4, plunger 5, outlet valve 6, oiling valve 7, removable connector 8, first clamp 9, second clamp 10 and box cupling are formed, pump barrel 4 is housed in the oil pipe 1, plunger 5 is housed in the pump barrel 4, the lower end of the upper end of plunger 5 and plunger link 2 is by being threaded togather, black box 3 is fixed on the pump barrel 4 by screw thread, realize the sealing between pump barrel 4 and the plunger 5, the lower end of pump barrel 4 is connected by the upper end of screw thread with removable connector 8, removable connector 8 is stuck on the box cupling of oil pipe 1 bottom by second clamp 10, outlet valve 6 is stuck on the pump barrel 4 by first clamp 9, oiling valve 7 by screw-thread securing on removable connector 8.Described outlet valve 6 and oiling valve 7 are elastic material.
The present invention has following beneficial effect:
1. the present invention cancels rigid seal between pump barrel and the plunger, adopts black box to realize flexible sealing between pump barrel and the plunger, and this structure can reduce friction, improves pump efficiency.
2. the present invention has cancelled the valve ball of conventional oil well pump, and the oiling valve and the outlet valve that adopt rubber to make are finished the pumping process, and this structure can make sealing more reliable, reduces physical dimension.
3. the present invention adopts dismountable link, need not oil outlet tube during maintenance, only needs to carry oil well pump, unties clamp 10 and just pump can be risen to ground, is easy to operation, is convenient to maintenance, has saved the activity duration, has reduced labor strength.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1, present embodiment is by oil pipe 1, plunger link 2, black box 3, pump barrel 4, plunger 5, outlet valve 6, oiling valve 7, removable connector 8, first clamp 9 and second clamp 10 are formed, pump barrel 4 is housed in the oil pipe 1, plunger 5 is housed in the pump barrel 4, the lower end of the upper end of plunger 5 and plunger link 2 is by being threaded togather, black box 3 is fixed on the pump barrel 4 by screw thread, realize the sealing between pump barrel 4 and the plunger 5, the lower end of pump barrel 4 is connected by the upper end of screw thread with removable connector 8, removable connector 8 is stuck on the box cupling of oil pipe 1 bottom by second clamp 10, outlet valve 6 is stuck on the pump barrel 4 by first clamp 9, oiling valve 7 by screw-thread securing on removable connector 8.
Embodiment two: in conjunction with Fig. 1 present embodiment is described, the outlet valve 6 of present embodiment and oiling valve 7 are elastic material and make.The elastic material of making outlet valve 6 and oiling valve 7 is rubber, modified rubber or rubber and plastic.
Above-mentioned elastic-sealing-valve oil pump, its working principle is: in the pumping process, plunger 5 is done upper and lower to-and-fro motion with the motion of power mechanism in pump barrel 4.When plunger 5 up strokes, pump chambers 11 spaces increase, the effect of pump external and internal pressure makes and forms Negative Pressure Difference in the pump chambers 11, elasticity outlet valve 6 is subjected to pump barrel outside liquid high pressure and makes outlet valve 6 closures, liquid high pressure is opened oiling valve 7 in the well, and liquid enters by oiling valve 7 and is full of pump chambers 11 in the well.When plunger 5 down strokes, space compression in the pump chambers 11 forms high pressure, makes elasticity oiling valve 7 closures, and outlet valve 6 is opened, and liquid passes through outlet valve 6 excavationg pump chambers to oil pipe 1 in the pump chamber.Plunger 5 upper and lower continuous to-and-fro motion just constantly are pumped into well liquid in the oil pipe 1, enter gathering system by well head.
