Abstract
The utility model discloses a multi-cylinder pump plunger installation device, which is a special installation tool for a multi-cylinder pump plunger. The multi-cylinder pump plunger installation device comprises a pushrod, an end cap and an outer shell, wherein the pushrod is installed in the end cap to connect the end cap with the outer shell. The multi-cylinder pump plunger installation device has the advantages that since the existing threaded structure of a multi-cylinder pump cylinder body is fully utilized, the anchoring of the outer shell of the tool on the cylinder body is realized; since the force for turning the pushrod is converted into the pushing force of the plunger, the installation process of the plunger is enabled to be safe, stable and very labor-saving; since an inner bush is additionally installed in the outer shell, the better effects of protecting the plunger and righting the plunger can be achieved and the damages to the plunger and sealing elements are reduced; not only can the working efficiency be improved and the labor intensity of workers be reduced, but also the maintenance cost is reduced.
Description
Technical field
The utility model relates to the maintenance tool of plunger displacement pump, and particularly a kind of multicylinder pump plunger erecting device, is the installation special tool of multicylinder pump plunger.
Background technology
In the fracture acidizing construction of petroleum industry, multicylinder pump is widely used.In use, owing to often sucking all kinds of impurity, very easily cause the damage of internal valve member and spring and sealing ring, maintenance is frequent, and the work of dismantling and installing plunger is numerous and diverse.At present, the common way that plunger is installed is: three people coordinate, and adopts crowbar righting, with sledgehammer, plunger is driven in cylinder body.This installation method has not only increased workman's labour intensity, simultaneously, plunger will pass the precision elements such as first ring, pressure rings, shading ring, oil-scraping ring, O RunddichtringO in progradation, easily these sealing precision elements is caused to certain physical damnification, causes installing unsuccessfully.Production scene needs the erecting tools of multicylinder pump plunger.
Summary of the invention
The purpose of this utility model is to provide a kind of multicylinder pump plunger erecting device, installment work for multicylinder pump plunger, in installation process, can alleviate plunger damage to precision sealing element in push-on process to plunger righting, reduce workman's labour intensity and cost of equipment maintenance.
The utility model is achieved in that a kind of multicylinder pump plunger erecting device comprises pushing ram, end cap and shell body, and pushing ram is contained in end cap, and end cap is connected with shell body.
The beneficial effects of the utility model are: the utility model takes full advantage of the existing helicitic texture of multicylinder pump cylinder body, the grappling of the shell body of having realized instrument on cylinder body.The power of rotating pushing ram is converted into the motive force of plunger, makes the installation process safety and steady of plunger and very laborsaving.In shell body, install neck bush additional, can play better the effect of protection plunger, righting plunger, reduced the damage to plunger and potted component.Not only improve operating efficiency, reduced workman's labour intensity, also reduced maintenance cost, there is good result of use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.Referring to Fig. 1, a kind of multicylinder pump plunger erecting device comprises pushing ram 2, end cap 3 and shell body 5, and pushing ram 2 is contained in end cap 3, and end cap 3 is connected with shell body 5.Pushing ram 2 is provided with external screw thread, and lower end outer end diameter is greater than body of rod external diameter, and boosting-rod 1 or afterburning handle are installed in upper end.The cylindrical of end cap 3 is provided with that external screw thread is connected with shell body 5, its centre bore is provided with internal thread and is connected with pushing ram 2.Shell body 5 is cylindrical body, and bottom cylindrical is provided with external screw thread and is connected with cylinder body, and lower end inner circle is provided with neck bush limiting stand, and neck bush 4 is housed in shell body 5.Neck bush 4 is manufactured by the material of the softwood matter such as nylon, plastic cement, copper, plays the effect of protection plunger.
Pushing ram 2 is threaded with the centre bore of end cap 3, can in pushing ram 2 length ranges, move, and the upper end of pushing ram 2 coordinates and realizes moving axially of pushing ram 2 with boosting-rod 1 or afterburning handle, and the lower end of pushing ram 2 is withstood on the plunger end face that needs to install.The bottom cylindrical of shell body 5 has external screw thread, and its button-type matches with the internal thread on multicylinder pump cylinder body, and the top inner circle of shell body 5 has internal thread to be connected with end cap 3.When plunger is installed, shell body 5 is realized and being threaded with cylinder body through plunger.Then, pushing ram 2 is fallen back on to minimum stroke, the assembly of end cap 3 and pushing ram 2 formations is connected on shell body 5, use boosting-rod 1 or afterburning handle evenly to rotate pushing ram 2, pushing ram 2 slowly touches plunger, promotes and realize the installation of plunger.The endoporus aperture of neck bush 4 is slightly larger than the external diameter of plunger, is enclosed within on plunger, can play better the effect of protection plunger, righting plunger.
