Abstract
The square flange extracting tool of water injecting pump stuffing box, relates to detaching tool for flange.Comprise stuffing box, one end of stuffing box is connected with stuffing box gland, plunger has been placed in stuffing box, the other end of stuffing box is connected on the pump housing by square flange, the pump housing is fixed with screw rod, square flange is fixed on the screw rod of the pump housing by the first nut, it is characterized in that: the outer end of described stuffing box gland is fitted with fixed head, one end that described plunger stretches out stuffing box gland passes outwards through fixed head, described square flange is evenly equipped with at least two screwed holes, be threaded in screwed hole pull bar respectively, the other end of pull bar is respectively arranged with screw thread, the other end of pull bar is passed outwards through fixed head and is fixed by the second nut.The beneficial effects of the utility model: fixed head is close to by (1) pull bar, and amount of movement can be consistent.(2) square flange and fixed head define the stable cubold of uniform force, realize synchronizing moving.
Description
Technical field
The utility model relates to detaching tool for flange, is specially a kind of square flange extracting tool of water injecting pump stuffing box.
Background technology
5ZB type plunger displacement pump because its pump efficiency is high, larger pressure can be born and be widely used in oil-field flooding work.
The stuffing box square flange dismounting of this model plunger displacement pump is a common action in daily maintenance, and changing plunger, packing press ring etc. all needs method for dismounting blue.The square flange front of prior art is equipped with two top wire holes, is tightened by ∮ 16 bolt, the method for pressing method orchid and pump case body, and bootstrap technique is blue outwards mobile.
There is open defect in this method for dismounting:
1, jackscrew is stressed asynchronous.Upper and lower two jackscrews are one in front and one in back stressed, and amount of movement is inconsistent.Easily cause deflection, after deflection, the granule foreign in square flange and pump case gap extrudes, and increases the resistance of advance.
2, stuffing box is from great, causes center of gravity unstability, has integral sinking effect, and Impact direction changes, will resistance.
3, working space is little, inefficiency.Working space is restricted, and the activity point of view of spanner is no more than 15 °, and can only use the double offset ring spanner of M24, can only have 8 centimeters in operating space between stuffing box.
Utility model content
The purpose of this utility model is to provide one and can effectively increases work efficiency, and each parts uniform force in unloading process, the square flange extracting tool of the water injecting pump stuffing box operated steadily.
The technical scheme realizing above-mentioned purpose is: the square flange extracting tool of water injecting pump stuffing box, comprise stuffing box, one end of stuffing box is connected with stuffing box gland, plunger has been placed in stuffing box, the protruding stuffing box gland in one end of plunger, the other end of stuffing box is connected on the pump housing by square flange, the pump housing is fixed with screw rod, square flange is fixed on the screw rod of the pump housing by the first nut, it is characterized in that: the outer end of described stuffing box gland is fitted with fixed head, one end that described plunger stretches out stuffing box gland passes outwards through fixed head, described square flange is evenly equipped with at least two screwed holes, be threaded in screwed hole pull bar respectively, the other end of pull bar is respectively arranged with screw thread, the other end of pull bar is passed outwards through fixed head and is fixed by the second nut.3
The course of work of the present utility model is:
1, first nut of fixing means orchid is laid down;
2, on fixed head, tighten the second nut of pull bar, stuffing box presses pump case under the pressure of fixed head, and square flange is outwards movement under the drive of pull bar.
The beneficial effects of the utility model:
(1) fixed head is close to by pull bar, and amount of movement can be consistent.
(2) square flange and fixed head define the stable cubold of uniform force, realize synchronizing moving.
(3) stuffing box stressed after press pump case, weight can not act on square flange and drive square flange integral sinking.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the front view of stuffing box.
Detailed description of the invention
As Fig. 1, 2, shown in 3, the utility model comprises stuffing box 1, one end of stuffing box 1 is connected with stuffing box gland 2, plunger 3 has been placed in stuffing box 1, the protruding stuffing box gland 2 in one end of plunger 3, the other end of stuffing box 1 is connected on the pump housing 5 by square flange 4, square flange 4 is provided with center hole 6, the all inwalls of ring of center hole 6 are evenly equipped with multiple square flange briquetting 7, the ring week of one end that stuffing box 1 is connected with square flange 4 is provided with the stuffing box briquetting 8 coordinated with square flange briquetting 7, the stuffing box briquetting 8 of stuffing box 1 end is placed in the rear portion of square flange briquetting 7, and by screw rod 9, first nut 10 is fastened on the pump housing 5, one end of described screw rod 9 is fixed on the pump housing 5.
The outer end of stuffing box gland 2 is fitted with fixed head 11, and one end that plunger 3 stretches out stuffing box gland 2 passes outwards through fixed head 11, square flange 4 is evenly equipped with two jackscrew screwed holes 12.The two ends of pull bar 13 are respectively arranged with screw thread, and one end is connected on jackscrew screwed hole, and the other end is passed outwards through fixed head 11 and fixed by the second nut 14.
