Description
Technical field
The utility model relates to plunger pump system technical field, specifically a kind of well cementation plungers pump plunger replacer.
Background technique
Plunger pump is an important device in well cementation unit, it is moved back and forth in cylinder body by plunger, makes to seal work
The volume for making cavity changes to realize that the fluid pressures such as oil suction, pressure oil are driven.Plunger pump has rated pressure height, structure tight
It gathers, the advantages that high-efficient and flow is easy to adjust, is widely used in the occasion that high pressure, big flow and flow need to adjust, it is all
Large scale equipment uses plunger pump as hydrodynamic source such as on land and offshore platform.
In land and offshore platform, well group operation, completion practice etc. will usually use cementing truck and carry out well cementing operation,
The plunger pump device in cementing truck is frequently used for liquid power transmission in well cementing operation thus.And in use process, plunger damage
Disassembly link when bad or inspection work needs often operation.A kind of disassembly is needed to pacify for the cementing truck characteristic of this platform
Assembling device is convenient for the repair and maintenance of plunger pump.
Plunger pump is in replacement plunger every time or plunger packing, since the gap of plunger and plunger packing is smaller, especially
It is winter, it is often relatively difficult and time-consuming and laborious when plunger returns dress.
Utility model content
In order to overcome the disadvantages described above and deficiency of the prior art, the purpose of the utility model is to provide one kind can be more square
Just a kind of well cementation plungers pump plunger replacer of installing and dismounting.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of well cementation plungers pump plunger replacer,
Including screw rod and gland, described screw rod one end is equipped with the rotation slip-knot of press plunger, the other end be equipped with convenient for spanner it is fixed and
The polygon packet turned, the gland inner cavity are equipped with internal screw thread corresponding with screw rod, and outer surface is equipped with assembly external screw thread,
The gland is connect by internal screw thread with screw flight, and the painstaking point of support of rotating joint is constituted.
Preferably, the rotation slip-knot includes press block and rotation connection block, the briquetting is connected by rotation
It connects block and screw rod is rotatablely connected.
Preferably, the polygon packet includes the polygonal body being correspondingly arranged with wrench opening, it is described
Polygonal body one end offers the internal thread hole for accommodating interior hexagonal line spanner.
Preferably, the gland periphery is fixed with several uniformly distributed hand rest protrusions, the hand rest protrusion and pressure
Lid is an integral structure.
Preferably, the press block is cylindrical column, fillet has been led in end.
Further, the press block is cylindrical column, and end is hemispheric end face.
The beneficial effects of the utility model are: well cementation plungers pump plunger is simple and reasonable, it is capable of the peace of convenience and high-efficiency
Assembly and disassembly improve the efficiency of maintenance work.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the mounting structure schematic diagram of the utility model.
In figure: 1. screw rod, 2. gland 3. rotates slip-knot 4. and presses the rotation connection 6. polygon packet 7. of block of block 5.
8. internal thread hole of polygonal body, 9. internal screw thread .10. assembles 11. hand rest of external screw thread protrusion
Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with attached drawing and embodiment, the utility model is further elaborated.It should be appreciated that embodiment described herein is only used
In explaining the utility model, it is not used to limit the utility model.
As shown in Figs. 1-2, a kind of well cementation plungers pump plunger replacer, main body include screw rod 1 and gland 2, the screw rod 1
One end is equipped with the rotation slip-knot 3 of press plunger, and the other end is equipped with the polygon packet 6 fixed and turned convenient for spanner, described
2 inner cavity of gland be equipped with internal screw thread 9 corresponding with screw rod 1, outer surface is equipped with assembly external screw thread 10, and the gland 2 passes through interior
Screw thread 9 is threadedly coupled with screw rod 1, constitutes the painstaking point of support of rotating joint 5.
Rotating slip-knot 5 includes press block 4 and rotation connection block 5, and the briquetting 4 passes through rotation connection block 5 and screw rod 1
Rotation connection.
Polygon packet 6 includes the polygonal body 7 being correspondingly arranged with wrench opening, and described 7 one end of polygonal body is opened
Equipped with the internal thread hole 8 for accommodating tap wrench, spanner (interior hexagonal or outer-hexagonal) is easy to use to carry out make-up or loose unloading screw rod.
For the ease of the operation and installation of gland, 2 periphery of gland is fixed with several uniformly distributed hand rest protrusions 11, institute
The hand rest protrusion 11 stated is an integral structure with gland 2.
It is positioned in order to be more convenient for, and improves the accuracy and efficiency of press, the press block 4 is cylindrical column
Shape body, it is that cylindrical column end is set as hemispheric end face that end, which leads fillet or will press block,.
Well cementation plungers pump plunger replacer mainly utilizes the screw thread principle of reaction, the realization plunger and packing being simple and efficient
Dismounting problem, reduce maintenance of equipment bring well on operating condition delay.Improve equipment mechanical discipline, mechanization and simple
Change and uses.A large amount of manpowers, financial resources and material resources and the output of the maintenance of equipment of time are reduced, personal safety guarantee is improved, avoids not
Necessary safety accident.Working efficiency is improved, ensures that equipment is effectively operated to realize that drilling benefit maximizes.
Operation step, which is played, to be described below:
(1) plunger is fit into suitable by the reaction force pressed using 1 screw thread of screw rod and rotating joint 3 in cylinder body
Position.
(2) upper water cavity, drainage cavity is opened, and is taken out valve body (a kind of check valve), removes the cement block on plunger；
(3) it is rotated counterclockwise using this replacer and takes out plunger, replaced plunger packing first plunger；
(4) packing and plunger surface smear machine oil, put plunger channel into, replacer is mounted on plunger pump ontology, benefit
With the reaction force of screw plunger jacking is gone slowly, until tightening.
The above-mentioned preferred embodiment for being only used for illustrating, within the spirit and principle of the utility model institute
Any modifications, equivalent replacements and improvements of work, shall fall within the scope of the present invention.
