The technical scheme is that the plunger pump packing replacement device mainly comprises a fixing disc and a dismounting hook; the fixing disc comprises a threaded connector and a pressing cover; the threaded connector is connected with the pressing cover; three threaded through holes are uniformly distributed in the pressing cover; the dismounting hook consists of a fixing end and a connecting rod; the fixing end is provided with an outer thread; and one end of the connecting rod is connected with the fixing end, and the other end of the connecting rod is provided with a hangnail hook which is fixed on the pressing cover through a screw cap. The plunger pump packing replacement device provided by the utility model has the beneficial effects of being easy to use, and simplifying the operation steps, and a square flange is not required to be used for dismounting a pump head; a plunger is not required to be taken out, and only the pressing cover is required to be dismounted, so that the time and the labor are saved; a pump body structure is utilized reasonably, a tool is fixed on a pull rod and is firm and reliable; the tool is driven to operate through rotating a belt wheel; and the plunger pump packing replacement device has relatively great traction, and is convenient and rapid to take a packing by utilizing a hangnail.
Description
One, technical field
The utility model relates to a kind of packing replacing tool, particularly a kind of plunger displacement pump packing replacing device.
Two, background technology
Plunger displacement pump is Shengli Oil Field a kind of water injection equipment commonly used, and it relies on plunger to move back and forth in cylinder body, makes the volume of seal operation cavity volume change to realize pressurized water injection.Because the plunger displacement pump water injection pressure is high, it is fast that plunger moves back and forth speed, causes packing quick abrasion, easily thorn leakage.The instrument of in the past changing the plunger displacement pump packing is relatively heavier, uses conventional methods the replacing packing, must unload first the large gland of this group assembly, lays down four fixed screws of pump head square flange again.After taking off the pump head square flange, need to take out a whole set of valve assembly in the pump head with instrument, change packing at every turn and be equivalent to a whole set of valve assembly of dismounting, plunger and packing.Frequently dismounting is easily to valve seat and valve sheet injury.When getting plunger with the pipe wrench rotation again, pipe wrench is easy to the damage of the screw thread of plunger is needed to change a whole set of diameter 45mm plunger after the damage.1 year needs, 8 covers of more exchanging treaties, sometimes even more, operating procedure is quite loaded down with trivial details, and time-consuming, effort has increased workman's labour intensity.
Three, summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of plunger displacement pump packing replacing device is provided, and uses simple, time saving and energy saving.
Its technical scheme is: mainly be comprised of fixed disk and dismounting hook, described fixed disk comprises threaded connector and gland, and threaded connector connects gland, and three tapped through holes evenly distribute on the described gland; Described dismounting hook is comprised of stiff end and connecting rod, and stiff end is provided with external screw thread, and an end of connecting rod is connected and fixed end, and the other end of connecting rod is provided with the hangnail hook; Described dismounting hook is fixed on the gland by nut.
The beneficial effects of the utility model are: use simply, need not dismantle the square flange of pump head, simplified operating procedure; Plunger need not be taken out, only lower cover need be unloaded, time saving and energy saving; Rationally utilize pump body structure, instrument is fixed on the pull bar, and is solid and reliable, drives tool work by rotating pulley, has than large traction, utilizes the hangnail hook to get packing, convenient and swift, alleviated workman's labour intensity.
Four, description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of fixed disk;
Accompanying drawing 3 is structural representations of dismounting hook;
Among the upper figure: fixed disk (1), threaded connector (1.1), gland (1.2), tapped through hole (1.3), dismounting hook (2), stiff end (2.1), connecting rod (2.2), hangnail hook (2.3), nut (3).
Five, the specific embodiment
1-3 by reference to the accompanying drawings, the utility model will be further described:
The utility model mainly is comprised of fixed disk 1 and dismounting hook 2, and described fixed disk 1 comprises threaded connector 1.1 and gland 1.2, and threaded connector 1.1 connects gland 1.2, and three tapped through holes 1.3 evenly distribute on the described gland 1.2; Described dismounting hook 2 is comprised of stiff end 2.1 and connecting rod 2.2, and stiff end 2.1 is provided with external screw thread, and an end of connecting rod 2.2 is connected and fixed end 2.1, and the other end of connecting rod 2.2 is provided with hangnail hook 2.3, hangnail hook 2.3 inclinations 45 degree; Described dismounting hook 2 is fixed on the gland 1.2 by nut 3.
The new tool operational procedure:
1, termination of pumping, the emptying of refluence journey;
2, the dish pump heads into a segment distance in the annular seal space with plunger, loosens the screw thread between plunger and pull bar, again coils pump, and pull bar is separated with plunger, takes off gland;
3, erecting tools, by tightening screwed connection to pull bar, bill must be able to pass 3 apertures of copper packing with the stiff end of instrument;
4, collude and get packing, the moving belt pulley of dish advances instrument in annular seal space, puncture packing with bill.The moving belt pulley of dish catches on packing with bill again, and packing and copper packing are taken out in the lump;
5, extracting tool is rotated counterclockwise instrument, and it is separated with pull bar, taking off tool and old packing;
6, new packing is installed, with even coating butter inside and outside the new packing, respectively 6 packings and copper packing is stuck on the plunger, with sleeve with in the packing indentation sealing chamber;
7, connect plunger, after the upper gland, plunger is connected on the pull bar.
Principle: be connected with plunger closely with packing for the existing copper mat, be difficult for taking out the present situation of packing, copper packing is got out 3 apertures that are evenly distributed on the original basis, stressed even when hooking up packing with assurance, and do not destroy its reliability.The specific purpose tool of getting packing is colluded in making, and fixed disk is threaded connection 1.1 and is connected on the pull bar, utilizes the original screwed hole of pull bar, this instrument of connection that can be fastening.The other end of connecting rod is provided with the hangnail hook, utilizes it to pass the aperture of copper packing, and penetrates packing with colluding point, in the process of taking out, utilizes the hangnail that colludes point to catch on packing, by rotating pulley, packing, copper packing is taken out in the lump.
Note during the tool using concrete operations: 1, the bill of instrument is sharper, it should be noted that during use and avoids bill to hurt sb.'s feelings; Should note and can not overexert when 2, instrument uses, in order to avoid the damage bill, the time spent does not need to seal up for safekeeping with protective sleeve.
