Abstract
The utility model discloses a plunger pump plunger-assembler used in petroleum industry, which is used at drilling platforms, oil production platforms and construction sites of workover operation on land to exchange plungers for plunger pumps. The plunger pump plunger-assembler comprises a pressure cap, a combined baffle, a positioning baffle, a thrust nut and a screw rod. The combined baffle, the positioning baffle and the thrust nut are mounted at the front end of the screw rod, and the pressure cap is mounted on the rod body of the screw rod. By utilizing the plunger pump plunger-assembler, the time for disassembling and mounting the plunger and exchanging valves can be shortened from the original 5 hours to the present half an hour, thereby reducing the labor intensity of workers, avoiding various fees for outward maintenance, increasing the work efficiency, reducing the production cost, reducing the damage to the work-pieces and increasing the service life of the plunger pump.
Description
Technical field
The utility model belongs to the auxiliary equipment of petroleum industry workover treatment, plungers pump plunger assembler particularly, and the job site that is used in drilling platforms, production platform and land workover treatment is that plunger displacement pump is changed plunger.
Background technology
In the job site of petroleum industry, plunger displacement pump is the special equipment of technologies such as well-flushing, kill-job, fishing sleeve mill, sand washing.Plunger displacement pump just needs to change packing after using 100-200 hour.When changing packing, the scene does not have specific purpose tool, and the way that adopts artificial crowbar, hammer to knock is usually taken out packing from pump barrel.Adopt the same mode of knocking that new packing is pounded in the pump barrel when packing new packing into.During the loading and unloading packing, damage pump barrel and packing easily, shorten the service life of plunger displacement pump,, then can not finish rapidly at the construction field (site), need manufacturer to arrive on-the-spot repair and replacement if change the plunger of plunger displacement pump.The maintenance of plungers pump plunger system is wasted time and energy, and has a strong impact on production efficiency, increases production cost.
Summary of the invention
The purpose of this utility model is a design plungers pump plunger assembler, and for the ordinary maintenance of plunger displacement pump provides specific purpose tool, promptly safety is convenient again in assembling process at the scene to make it.
The purpose of this utility model is achieved in that the plungers pump plunger assembler comprises pressure cap, combination baffle, positioning baffle, Thrust nut and screw rod, combination baffle, positioning baffle and Thrust nut are installed in the front end of screw rod, and pressure cap is installed on the body of rod of screw rod.
Compare with existing maintenance mode, the utlity model has following obvious effects: the utility model is simple to operate, and turning handle utilizes moving forward and backward of screw rod, drives combination baffle and moves forward and backward, by combination baffle loading and unloading packing.When getting plunger, combination baffle is dismantled, utilize pressure cap to block the dismounting endoporus of plunger end face, rotate this instrument and get final product as interior square head wrench.This instrument of being rotated counterclockwise is that plunger is taken out in shackle, and this instrument that turns clockwise is that plunger is installed, and is simple and convenient.Make the combination baffle of 3 different sizes, make its external diameter be suitable for the different inner diameters of packing pressure ring, seal cartridge, valve seat, valve, realize taking-up and installation packing pressure ring, seal cartridge, valve seat, valve.This instrument of use demolition, installation plunger, replacing valve can shorten to present half an hour by original five hours, have reduced working strength of workers.Avoid the various expenses of outward transport maintenance, improved operating efficiency, reduced production cost, reduced the workpiece damage, improved the service life of plunger displacement pump.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described: referring to accompanying drawing, the plungers pump plunger assembler comprises pressure cap 2, combination baffle 3, positioning baffle 4, Thrust nut 5 and screw rod 6, combination baffle 3, positioning baffle 4 and Thrust nut 5 are installed in the front end of screw rod 6, pressure cap 2 is installed on the body of rod of screw rod 6, and the rear end of screw rod 6 is provided with handle 1.Combination baffle 3 is provided with 3 kinds of sizes, and its external diameter is conformed to the internal diameter size of packing pressure ring, seal cartridge, valve and the valve seat of plunger displacement pump respectively.The external diameter of pressure cap 2 is provided with screw thread, and pressure cap 2 matches with plunger displacement pump pump barrel inner end diameter, this instrument is fixed on the end of pump barrel.The loading and unloading of the profile of Thrust nut 5 and plungers pump plunger end face conform to the shape of endoporus, are interior six sides as loading and unloading with endoporus, and just Thrust nut 5 being manufactured becomes six square nuts.
Concrete use is as follows: pressure cap 2, combination baffle 3, positioning baffle 4 and Thrust nut 5 are installed on the screw rod 6 according to accompanying drawing.The combination baffle 3 of different size is installed as required, pressure cap 2 is screwed into the end of plunger displacement pump pump barrel.Turning handle 1 is by installing different combination baffles 3 dismounting packings, packing pressure ring, seal cartridge, valve and valve seat.When getting plunger, combination baffle 3 and positioning baffle 4 are dismantled, utilize Thrust nut 5 to block the interior square hole of loading and unloading of plunger end face as interior square head wrench.Rotary handle 1, being rotated counterclockwise shackle is that plunger is taken out, turning clockwise is that plunger is installed.
