Abstract
The utility model relates to a packing seal structure of a centrifugal coal pulp pump which is a single stage single suction vertical pump with a cantilever construction. The vertical pump mainly comprises a pump base, a pump bracket, an impeller, an impeller shaft, a front cover board, a rear cover board, stuffing, a stuffing ring, and a stuffing plate. The stuffing seal structure is a detachable integral stuffing seal, a shaft housing is arranged on the impeller shaft corresponding to the position placing the stuffing, a plurality of stuffing is arranged at the periphery of the shaft housing tightly, and the seal is realized by pressing the stuffing ring. The stuffing is connected with the stuffing ring through bolts, and the gasket-type seal can be realized by using a metal-shielded gasket. The stuffing seal structure of the centrifugal coal pulp pump of the utility model has good tightness, can quickly disassembled, is convenient for taking the packing out and putting the packing in from the two sides, and has practical value.
Description
Technical field
The utility model relates to a kind of FLUID TRANSPORTATION pump, relates in particular to a kind of packing seal structure of centrifugal coal slurry pump.
Background technique
In " coal system oil " direct liquefaction commercial plant, the packing seal structure of centrifugal coal slurry pump is as the VACUUM TOWER BOTTOM pump, in " coal system oil " direct liquefaction technological process, the VACUUM TOWER BOTTOM pump is as recycle pump, its performance characteristic and the effect in whole process flow thereof directly translate into high reliability and can safeguard fast, and for packing seal, its main regular maintenance is the replacing of filler, because the hot properties of the pump housing and the operational characteristic of pump, determined that the replacing of filler must be convenient and swift, finish at short notice, and conventional packing seal structure can't satisfy such requirement.
Summary of the invention
The purpose of this utility model provides a kind of packing seal structure of centrifugal coal slurry pump exactly in order to address the above problem.
The purpose of this utility model is achieved in that a kind of packing seal structure of centrifugal coal slurry pump, described centrifugal coal slurry pump is a cantilever structure one step single sucking vertical pump, mainly comprise pump seat, pump bracket, impeller, impeller shaft, front shroud, back shroud, filler, Gland and filler baffle plate, described packing seal structure is detachable whole packing seal, on described impeller shaft, be with axle sleeve corresponding to the position of laying filler, many fillers are closely arranged the periphery that is arranged on this axle sleeve, are compressed by Gland and realize sealing; Be connected with bolt between described filler and the filler baffle plate, and with metallic cover pad static seal.
Described packing seal structure also comprises a packing ring, and this packing ring replaces two fillers and is arranged on the periphery of axle sleeve, and is provided with the sealing liquid import on the Gland of relevant position, can inject the sealing liquid auxiliary seal as required.
The packing seal structure good airproof performance of the utility model centrifugal coal slurry pump, quick release, convenience is taken out from both sides and is put into filler, has use value.
Description of drawings
Fig. 1 is the general structure cross-sectional schematic of the related centrifugal coal slurry pump of the utility model;
Fig. 2 is the right side view of coal slurry pump shown in Figure 1;
Fig. 3 is a packing seal structure schematic representation of the present utility model.
Embodiment
Referring to Fig. 1, Fig. 2, the centrifugal coal slurry pump that the utility model is related comprises pump seat 1, intake pipe 2, pad 3, front shroud 4, water exit end 5, impeller 6, back shroud 7, resistance packing plate 8, filler 9, packing ring 10, axle sleeve 11, bearing bracket 12, axle sleeve 13, angular contact ball bearing 14, electric machine support 15, coupling 16, water inlet heating chamber inlet tube 17, preceding heating chamber is imported and exported pipe 18, middle heating chamber is imported and exported pipe 19, motor 20, locking nut 21, bearing cap 22, bearing support 23, impeller shaft 24, roller bearing 25, bearing cap 26, Gland 27, flushing oil inlet tube 28, filler 29, back heating cavity 30, filler baffle plate 31, resistance envelope impeller 32, back heating chamber is imported and exported pipe 33, adjust pad 34, pump bracket 35 and water inlet heating chamber outer pipe 36.
Consider the solid matter that the slag stock pump is carried, the pump flow passage components are had very strong abrasion, thus the selecting for use of reasonable structural design and overcurrent part material, can guarantee the reliable running of pump, reduce the rate of wear of overcurrent component, prolong the working life of pump.Impeller 6 in the utility model and resistance envelope impeller 32 adopt nickel Hart alloys, and front shroud 4, water exit end 5, back shroud 7 adopt KmTBCr26.Because the gold machining manufacturability of high-abrasive material is relatively poor, direct and the contacted part of fed sheet of a media often need be changed again, so the utility model is designed to double-layer shell structure with it, by tolerance fit and bolton, whole flow passage components can reduce wear part like this by pump seat 1, pump bracket 35 and bearing bracket 12.
Cooperation is referring to Fig. 3, packing seal structure of the present utility model is detachable whole packing seal, on impeller shaft 24, be with axle sleeve 11 corresponding to the position of laying filler, many fillers 9 are closely arranged the periphery that is arranged on this axle sleeve, compress the realization sealing by Gland 27, be connected with bolt between filler 29 and the filler baffle plate 31, and with metallic cover pad 38 static seals.
Packing seal structure of the present utility model also comprises a packing ring 10, and this packing ring replaces two fillers 9 and is arranged on the periphery of axle sleeve 11, and is provided with sealing liquid import 201 on the Gland 27 of relevant position.According to reality sealing situation, then inject the sealing liquid auxiliary seal as needs; As not needing, then take out packing ring 10, and seal sealing liquid import 201, put into two fillers 9 in the place of putting packing ring 10 originally.
When changing filler 9, unclamp Gland 27 earlier, unclamp the connecting bolt between filler 29 and the filler baffle plate 31 again, from a side filler 9 is released, put into new filler 9 more successively, behind the replacing static seal pad that filler 29 is fastening, compress Gland 27 at last, finish the replacing of filler.
The utility model is applicable to chemical industry and the high place of impurity content high-temperature, coal liquefaction field.Also can be applicable to the high occasions of impurity content such as mine, power station, papermaking.
