Abstract
The utility model relates to an instrument is changed to screw pump seal receptacle, which comprises a plate body, along the equidistant three nylon pin that to follow plate body radial movement that is equipped with of circumferencial direction in the one side of plate body, the opposite side of plate body is used for connecting a two -way spanner. The utility model discloses can insert the shaft coupling hole with three nylon pins simultaneously, it is rotatory to drive the screw rod to fast, safely carry out demolising and installing of seal receptacle.
Description
Technical field
The utility model relates to a kind of extracting tool, the rapid tool change particularly on a kind of mechanical sealing base being applied to oil and gas multiphase flow screw pump.
Background technology
At present, oil and gas multiphase flow screw pump mechanically-sealing apparatus is when changing, owing to there is no specific purpose tool, the very difficult dismounting of its seal receptacle, the way of current employing three nylon pin subangle degree is inserted shaft coupling to connect in circular hole, use 1000mm crowbar once to prize nylon to nullify, mechanical sealing base is separated dismounting by the cooperation utilizing screw rod and village to overlap, lose time, workload is large, operating efficiency is low, nullify because crowbar prizes nylon, and nylon cancellation fails to fix on shaft coupling, there is the security risk of crowbar slippage simultaneously.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is: provide a kind of screw pump seal receptacle to change instrument, three nylon pins can be inserted coupler holes by it simultaneously, drive screw rod to rotate, thus fast, the dismounting carrying out seal receptacle of safety and installation.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of screw pump seal receptacle changes instrument, and comprise plate body, the one side of described plate body is along the circumferential direction provided with at equal intervals three nylon pins that can move radially along plate body, the opposite side of described plate body is for connecting a Two-way spanner.
Described screw pump seal receptacle changes instrument, described plate body is radially provided with three chutes, and described nylon pin can be fixed by set bolt or move on described plate body.
Described screw pump seal receptacle changes instrument, and described plate body is discoideus.
Described screw pump seal receptacle changes instrument, described plate body tabular triangular in shape.
Compared with prior art, adopt the utility model has the advantage of of technique scheme: dismounting and the installation that can be realized seal receptacle by the cooperation of fast two-way spanner and plate body, reach the object changing mechanical seal, need not use crowbar prize nylon nullify drive bolt rotary, easy to operate, time saving and energy saving, efficiency is high, safe and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be the utility model A to structural representation.
Description of reference numerals: 1-Two-way spanner; 2-plate body; 3-nylon pin; 4-set bolt; 5-chute.
Detailed description of the invention
Further describe the utility model below in conjunction with specific embodiments and the drawings, advantage and disadvantage of the present utility model will be more clear along with description.
As depicted in figs. 1 and 2, be respectively the utility model screw pump seal receptacle change the structural representation of instrument and A to structural representation, as seen from the figure, the utility model comprises a plate body 2, and described plate body 2, in tabular, can be raw sheet or triangle tabular, in the present embodiment, plate body 2 goes the triangle tabular of three arcs for plectane button, and its main purpose saves material, reduces costs.Wherein, equally spacedly on the periphery direction of plate body 2 be provided with three chutes 5, the direction of described chute 5 is consistent with the radial direction of raw sheet, a nylon pin 3 is provided with in each chute, what each described nylon pin 3 can be fixed by a set bolt 4 is arranged on described plate body 2, when rotating set bolt 4 and making nylon pin 3 loosen, nylon pin 3 just radially can move around in chute 5, thus adjustment three nylon pins 3 surround diameter of a circle to adapt to and to meet different model screw pump.
The utility model in use, according to the difference of screw pump coupling size, the position of adjustment nylon pin 3 is also tightened fixing with set bolt 4, nylon pin 3 of the present utility model is inserted in coupler hole, drive plate body 2 to rotate by fast two-way spanner 1, thus drive the bolt rotary in screw pump, utilize the interaction between screw rod and lining, realize dismounting and the installation of mechanical sealing base, reach the object changing mechanical seal.
Above explanation and embodiment are only exemplary, do not form any restriction to scope of the present utility model.It will be understood by those skilled in the art that and do not departing under spirit and scope of the present utility model and can modify to the details of technical solutions of the utility model and form or replace, but these amendments and replacement all fall in protection domain of the present utility model.
