Abstract
The utility model provides a packing installer for a polymer-injecting pump. The packing installer comprises a positioning sleeve and a guide sleeve. The positioning sleeve and the guide sleeve are arranged to be cylindrical, and the positioning sleeve is sleeved with the guide sleeve. The diameter of the front end of the positioning sleeve is larger than that of the rear portion of the positioning sleeve, the diameter of the rear portion of the positioning sleeve is the same as that of a packing box, and the inner diameter of a center hole of the positioning sleeve is the same as that of the packing box. The inner diameter of the front portion of the guide sleeve is larger than the outer diameter of the rear portion of the positioning sleeve, and the inner diameter of the rear portion of the guide sleeve is larger than the outer diameter of the packing box. The packing installer has the advantages that installation of packing is completed through propelling force of a connecting rod, operation procedures are compact, and the packing installer saves time and is effective; besides, it can be guaranteed that the overall packing keeps at a correct position in the installation process and is not subjected to eccentric wear, so that the work quality of packing replacement is improved.
Description
Technical field
The utility model relates to tertiary oil recovery polymer injector system, is specially polymer-injecting pump filler erector.
Background technique
Polymer-injecting pump is as the on-the-spot capital equipment injecting of polymer, in the poly-field extensive use of note, polymer-injecting pump adopts three cylinder-and-piston type reciprocating pumps, this pump comprises power end and fluid end, wherein fluid end coordinates plunger to-and-fro motion to reach the object of boosting by 3 groups of built-in one-way valves, rated pressure is 16MPa, and this pump has low shearing, discharge capacity is stable, pump efficiency is high, be convenient to the features such as maintenance.But because fluid end pressure-bearing is higher, plunger seal part adopts the "O"-ring of multiple prefabricated black tetrafluoro fibers and aramid fibre shuffling to build sealing group.Polymer-injecting pump is widely used in note polymerizing technology, and therefore the maintenance of polymer-injecting pump and maintenance are the emphasis of the poly-work of note.In polymer-injecting pump maintenance work, polymer-injecting pump replacement workload has accounted for 70% of overall maintenance load, and rate when directly having influence on polymer-injecting pump pump efficiency and injecting, is the topmost maintenance work of polymer-injecting pump.When installing, filler has three difficult points: the one, pack difficulty into, and for ensureing the sealing effect of plunger packing, the relative stuffing box internal diameter of filler external diameter has designed certain magnitude of interference, packs filler into more painstaking.The 2nd, pack rear location into difficult, need loaded down with trivial details installation procedure to ensure that installation do not tilt.The 3rd, behaviour does narrow space, and due to equipment own characteristic, three groups of stuffing boxes are co-located among the narrow and small pump housing, operate limited.
Therefore, traditional replacement method is dissected, improved, designed special filler erector, realize one-time positioning, the integral installation of filler filling.
Summary of the invention
The purpose of this utility model is to provide a kind of polymer-injecting pump filler erector, solves the problem of the installation filler inconvenience of above-mentioned prior art existence.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises setting sleeve and guide sleeve, it is characterized in that setting sleeve and guide sleeve are made as cylindrical, and setting sleeve is enclosed within guide sleeve; Setting sleeve point diameter is greater than rear portion diameter, and rear portion diameter equals stuffing box diameter, and center hole internal diameter equals warp in stuffing box; In guide sleeve front portion, through being greater than setting sleeve rear portion external diameter, rear portion internal diameter is greater than stuffing box external diameter.
Setting sleeve length is made as 90mm-95mm.
The utility model has the advantages that; Utilize the Driving force of connecting rod to complete the installment work of filler, programmed sequence of operations compactness, saves time effectively, and can guarantee that filler installation entirety keeps correct position, and not eccentric wear, has improved the workmanship of changing filler.
Accompanying drawing explanation
Accompanying drawing 1-structural representation of the present utility model;
1-setting sleeve in figure, 2-guide sleeve.
Embodiment
For further disclosing the technical solution of the utility model, below in conjunction with Figure of description, by embodiment, elaborate:
The utility model comprises setting sleeve 1 and guide sleeve 2, it is characterized in that setting sleeve 1 and guide sleeve 2 are made as cylindrical, and setting sleeve 1 is enclosed within guide sleeve 2; Setting sleeve 1 point diameter is greater than rear portion diameter, and rear portion diameter equals stuffing box diameter, and center hole internal diameter equals warp in stuffing box; Guide sleeve 2 is anterior interior through being greater than setting sleeve 1 rear portion external diameter, rear portion internal diameter is greater than stuffing box external diameter. making gland length in the stuffing box that will consider exist actually during setting sleeve and add upper plug first half range and still filler cannot be sent into the problem of bottom, for solving the problem that cannot put in place, setting sleeve is designed to 90mm-95mm, guarantees that bottom packing is accurate to position.When packing is installed, guide sleeve is enclosed within on stuffing box, due to filler chamber's narrow space, manually enforce setting sleeve and pack comparatively inconvenience of packing into, therefore by dish, move big belt pulley and drive the straight reciprocating motion of plunger pump flywheel mechanism drive link, promote polymer-injecting pump filler erector packing is packed into.Utilize the Driving force of connecting rod to complete the installment work of packing, programmed sequence of operations compactness, saves time effectively, and can guarantee that filler installation entirety keeps correct position, and not eccentric wear, has improved the workmanship of changing filler.
Claims (2)
1. a polymer-injecting pump filler erector, comprises setting sleeve and guide sleeve, it is characterized in that setting sleeve and guide sleeve are made as cylindrical, and setting sleeve is enclosed within guide sleeve; Setting sleeve point diameter is greater than rear portion diameter, and rear portion diameter equals stuffing box diameter, and center hole internal diameter equals warp in stuffing box; In guide sleeve front portion, through being greater than setting sleeve rear portion external diameter, rear portion internal diameter is greater than stuffing box external diameter.
2. polymer-injecting pump filler erector according to claim 1, is characterized in that: setting sleeve length is made as 90mm-95mm.
