Abstract
The utility model provides a quadrel extractor for a water injection pump, and aims to solve the problem that when a quadrel is detached during replacement of a gland packing between a plunger assembly and a pump head of a plunger type water injection pump, the quadrel of the plunger type water injection pump is rusted together with the pump body and is difficult to extract out. The quadrel extractor for the water injection pump comprises a quadrel locking body, a connecting rod and a buffer sleeve, wherein a slide is arranged on a sleeve body of the buffer sleeve, the connecting rod is penetrated in the buffer sleeve, a dowel pin is inserted in the connecting rod and the slide, and a binding disk is arranged at the rear end of the connecting rod to connect the quadrel locking body and the buffer sleeve in a threaded manner. The quadrel extractor for the water injection pump is simple in design, low in manufacturing cost and easy to operate; and the quadrel can be extracted easily with a pump rotating method, so that the work efficiency can be improved, labor intensity of a worker is reduced, operation is facilitated, the pump starting time rate is guaranteed, and the extractor has a remarkably use effect.
Description
Technical field
The utility model relates to the maintenance aid of petroleum industry water injection equipment, particularly water injecting pump quadrel extractor, dismantles quadrel while changing the airtight and watertight padding between assembly for plunger and pump head for plunger type water injection pump.
Background technology
In the injecting process in oil field, plunger type water injection pump maintenance load is larger, because it is applied to the occasion of low discharge, high pressure, therefore the airtight and watertight padding of plunger displacement pump is changed more frequent, due to reasons such as sewage corrosions, make plunger quadrel together with pump housing corrosion, quadrel cannot take out in the pump housing.The thick crowbar of general employing clashes into assembly pressure cap back and forth, utilizes assembly to drive quadrel left and right slightly to move up and down, makes to produce between quadrel and the pump housing way of gap and pump housing disengaging.Adopt while getting quadrel in this way, clash into back and forth assembly pressure cap and easily cause the damage of assembly and assembly pressure cap screw thread, device damage and personal safety accident easily occur.For a change this situation, need to there be a kind of convenient and practical water injecting pump quadrel extractor at scene.
Summary of the invention
The purpose of this utility model is to provide water injecting pump quadrel extractor, solves plunger type water injection pump quadrel together with pump housing corrosion, and quadrel takes out difficult problem.
The technical solution of the utility model is achieved in the following ways: water injecting pump quadrel extractor comprises quadrel lock body, connecting rod and buffering sleeve, the cylindrical shell of buffering sleeve is provided with slideway, connecting rod is set in buffering sleeve, interspersed steady pin in connecting rod and slideway, the rear end of connecting rod is provided with binding dish, and quadrel lock body is threaded with buffering sleeve.
Compared with the prior art the utility model has the following advantages:
1, use this instrument effectively to reduce and clash into back and forth the injury of assembly pressure cap to assembly and pressure cap screw thread, thereby guaranteed the safe operation of water injecting pump.
2, this tool design is simple, and cost of manufacture is low, easy operating, and the method for utilization dish pump just can easily be taken off quadrel, thereby increases work efficiency, and has reduced workman's labour intensity, and rate while guaranteeing turn on pump, has obvious result of use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of the utility model quadrel lock body.
The specific embodiment
For further disclosing the technical solution of the utility model, below in conjunction with accompanying drawing, by embodiment, elaborate.Referring to Fig. 1 and Fig. 2, water injecting pump quadrel extractor comprises quadrel lock body 1, connecting rod 2 and buffering sleeve 4, the cylindrical shell of buffering sleeve 4 is provided with slideway, connecting rod 2 is set in buffering sleeve 4, interspersed steady pin 3 in connecting rod 2 and slideway, the rear end of connecting rod 2 is provided with binding dish, and quadrel lock body 1 is threaded with buffering sleeve 4.Quadrel lock body 1 is discoid body, is provided with centre bore and internal thread, and its cylindrical is provided with lock pawl, and the contour structures of quadrel lock body 1 conforms to the structure of quadrel inner circle.Slideway two ends on buffering sleeve 4 are arcuate structures, and the width of its slideway is greater than the diameter of steady pin 3, and the diameter of its buffering sleeve 4 is less than the length of steady pin 3.The external diameter of connecting rod 2 rear end binding dishes conforms to the external diameter of bent axle pull bar, uses slips that binding dish and bent axle pull bar are fixed.
concrete use procedure:in the time water injecting pump assembly for plunger quadrel need being taken out, first assembly for plunger is taken out, quadrel lock body 1 to be inserted in quadrel and from quadrel and passed, rotation quadrel lock body 1, makes the lock pawl of quadrel lock body 1 that quadrel is held.Connecting rod 2 is put into buffering sleeve 4, connecting rod 2 is locked in slideway with steady pin 3, then buffering sleeve 4 and quadrel lock body 1 are threaded togather.Connecting rod 2 is connected with slips with water injecting pump bent axle pull bar.Dish dynamic crankshaft case belt pulley, crankcase pull bar drivening rod 2 moves, and when moving to ways-end, drives buffering sleeve 4 to move together with quadrel lock body 1.If quadrel is because tension cannot take out, can be by dish dynamic crankshaft case belt pulley, drivening rod 2 moves reciprocatingly in slideway, by inertia strength until quadrel is taken out.
