Abstract
The utility model belongs to liquid delivery machinery, and relates to a horizontal chemical engineering axial-flow pump, which is applicable to delivering various high-flow and low-lift corrosive liquid containing solid particles in industries of chemical engineering, smelting, alkali preparation, salt manufacturing and papermaking, light industry and the like. A pup joint is disposed at a matching position of a pump body and an impeller and is integrally connected with a flange of the pump body via bolts, a wear-resistant ring is additionally disposed at the position of a packing box of the pump body, the outer periphery of the wear-resistant ring is in interference fit with the pump body, and the inner periphery of the wear-resistant ring is in clearance fit with a shaft sleeve. The horizontal chemical engineering axial-flow pump is reasonable in structure, convenient in operation and low in repair cost, and can prevent nuts of the impeller from loosening.
Description
Technical field
The utility model belongs to a kind of liquid conveying machinery, is to be applicable to the big flow of industries such as chemical industry, smelting, system alkali, salt manufacturing, papermaking, light industry conveying, low lift, contains the horizontal axial-flow pump of the various corrosive liquids of solid particle.
Background technique
At present, traditional horizontal axial-flow pump impeller outer radius pump housing is the cast inblock structure, and pump work is after a period of time, since impeller high speed circular Zhou Xuanzhuan, the mobile pump housing position heavy wear that makes the impeller outer diameter place of fed sheet of a media, and pump performance descends and cisco unity malfunction.Traditional in addition horizontal axial-flow pump is adopting Spielpassung between the pump housings and the axle sleeve more on the Stuffing box position of the pump housing, after the wearing and tearing of the diametric clearance between the axle sleeve and the pump housing surpassed 8mm, seal leakage was serious, will cause equipment to stop.If will solve above-mentioned two problems, or repair pump housing abrasion position, or change the pump housing, but, repair or change the pump housing and cost an arm and a leg because the general material of horizontal axial-flow pump is alloy material, and pump housing diameter is all bigger; The impeller of traditional axial flow pump all adopts the locking of monolock jack panel in addition, and in the distribution pipes system of chemical industry axial-flow pump institute, usually do not dispose valve, when pump stops, impeller counter-rotating occurs with axle, the impeller nut phenomenon that gets loose often occurs, easily cause the damage of component such as impeller, pump shaft, cause whole pump normally to move at last.Therefore, be necessary traditional horizontal axial-flow pump is innovated and architecture advances.
Summary of the invention
The purpose of this utility model provides a kind of horizontal chemical industry axial-flow pump, and it is rational in infrastructure, easy to operate, maintenance cost is low, can prevent the horizontal chemical industry axial-flow pump that impeller nut gets loose.
Realize that the technological scheme that the utility model above-mentioned purpose adopts is: at the pump housing and impeller cooperation place a short circuit is set, short circuit fuses by bolt and pump housing flange; Set up a wear ring in the Stuffing box position of the pump housing, wear ring periphery and pump housing interference fit, interior week and axle sleeve Spielpassung.
Further technological scheme of the present utility model also comprises: adopt impeller nut and the twin-lock jack panel structure of locking jack panel that impeller is locked in the end of axle.
The beneficial effects of the utility model: 1. than traditional axial-flow pump design having increased a short circuit and a wear ring, short circuit that increases newly and wear ring have been realized the designing requirement that novel chemical industry axial-flow pump is rational in infrastructure, easy to operate, maintenance cost is low, this wear ring can increase the contact distance, reduce pressure medium, guaranteed the sealing reliability at filler place, reduced and handle or change the higher cost that the pump housing causes.Aspect installing/dismounting, the utility model device is compared with conventional apparatus has stronger operability, only needs replacing short circuit and wear ring to get final product after short circuit and wear ring wearing and tearing.2. change traditional monolock jack panel into the twin-lock jack panel, both realized operation, easy to maintenance, guaranteed that again pump does not cause the impeller nut phenomenon that gets loose when counter-rotating occurring, avoid novel chemical industry axial-flow pump impeller nut to get loose and caused the situation of damage of components such as impeller, pump shaft, reduce the operating cost of pump, improve the operational efficiency of pump.
Description of drawings
Below in conjunction with accompanying drawing and enforcement the utility model is done into explanation, but the utility model is not limited to shown in the accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Among the figure: impeller capping 1, lock jack panel 2, impeller nut 3, impeller 4, axle 5, the pump housing 6, wear ring 7, axle sleeve 8, Sealing 9, bearing support 10, short circuit 11, Stuffing box 12.
Embodiment
Referring to Fig. 1, in the pump housing 6 and impeller 4 cooperation places a short circuit 11 is set, short circuit 11 fuses by the flange of the bolt and the pump housing 6; A wear ring 7 is set up in Stuffing box 12 positions at the pump housing 6, the periphery of wear ring 7 and the pump housing 6 interference fit, interior week and axle sleeve 8 Spielpassung.Adopt impeller nut 3 and the twin-lock jack panel structure of locking jack panel 2 that impeller 4 is locked in the end of axle 5.
During installation, axle sleeve 8 is contained on the axle 5, with pack into the Stuffing box 12 of the pump housing 6 of wear ring 7, again sealed member 9 is packed into the Stuffing box 12 of the pump housing 6 is connected bearing support 10 parts that install axle 5 and the pump housing 6 by bolt, impeller 4 then is installed, impeller spiral shell 3 mothers, by locking jack panel 2 lockings, impeller capping 1 is connected on the impeller 4 again, short circuit 11 is installed at last by bolt.
Claims (2)
1. horizontal chemical industry axial-flow pump, it is characterized in that: at the pump housing and impeller cooperation place a short circuit is set, short circuit fuses by bolt and pump housing flange; Set up a wear ring in the Stuffing box position of the pump housing, wear ring periphery and pump housing interference fit, interior week and axle sleeve Spielpassung.
2. by the described horizontal chemical industry axial-flow pump of claim 1, it is characterized in that: adopt impeller nut and the twin-lock jack panel structure of locking jack panel that impeller is locked in the end of axle.
