Because Pulp pump is mainly used in exporting the high slurry of granule foreign thing content, so needing the power end in Pulp pump Sealing mechanism is set between pump case, and packing seal is most common seal form, pump shaft is generally comprised and is fixed on outside pump shaft Lumen side on axle sleeve on circumference, the excircle of axle sleeve from atmospheric side to pump is disposed with filler and seal cage, filler Outside is fixed by gland, is provided with internal flow channel on seal cage, and rear pump cover is set on the excircle of filler and seal cage, after The flushing mouth of a river is provided with pump cover, the flushing mouth of a river is corresponding with the position of the internal flow channel of seal cage, and gland is fixedly attached to On rear pump cover, it is connected by screw between rear pump cover and pump case.
Rinse to need to connect on the mouth of a river needs to access the water pump of certain lift to improve water on supply channel, supply channel Pressure, it is ensured that rinse the hydraulic pressure at the mouth of a river higher than hydraulic pressure in pump case, it is ensured that water seal effect;Contain in the liquid conveyed additionally, due to Pulp pump There is granule foreign more, in the course of work, the rear pump shell shell wall corresponding with impeller easily corrodes, and uses for a long time, can reduce The operating efficiency of Pulp pump.
The content of the invention
The purpose of this utility model is to overcome the defect of prior art, and there is provided a kind of low Pulp pump of flushing water pressure.
To achieve the above object, the utility model employs following technical scheme:
A kind of low Pulp pump of flushing water pressure, including pump shaft 1 and the impeller 2 that is connected with pump shaft 1, pump shaft 1 are arranged on It is connected on bracing strut 3 and by axle sleeve with bracing strut 3, impeller 2 is arranged in pump case, inlet is provided with pump case and goes out liquid Mouthful, filler 4, seal cage 5 and spacer 6, seal cage 5, spacer 6, rear pump cover 8 and impeller 2 are provided between axle sleeve and bracing strut 3 Between the flushing chamber 7 that constitutes, be provided with flushing water inlet, seal cage 5 on pump case and be provided with connection and rinse water inlet and flushing It is provided with the internal flow channel of chamber 7, the rear pump cover 8 of pump case with impeller 2 with respect to place in fixing groove, fixing groove and is provided with replacement block 9, Replacement block 9 is fixedly connected by bolt with rear pump cover 8;
Cross section is provided with for semicircular annular recess 10 with respect to place with impeller 2 on rear pump cover 8, and replacement block 9 is located at punching Wash chamber 7 anterior, annular recess 10, which is located at, rinses the rear portion of chamber 7;
The arc-shaped being provided with the side relative with impeller 2 of replacement block 9 between multiple rows of arc-shaped projection 91, adjacent row is convex Rise 91 relative to the side wall of replacement block 9 height of projection differ 2-5mm.
The utility model can effectively reduce the pressure rinsed during slurry pump operation in chamber 7, so as to reduce washing pressure.Separately Outside, rear pump cover 8 replaces the inwall of rear pump cover 8 to be contacted with rinsing the liquid in chamber 7 with respect to place with impeller 2 by replacement block 9, for a long time After use, replacement block 9 is corroded by granule foreign, can ensure that Pulp pump runs well by changing replacement block 9, effectively improve slag The service life of stock pump.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model rinses chamber;
In the accompanying drawings, 1 pump shaft, 2 impellers, 3 bracing struts, 4 fillers, 5 seal cages, 6 spacers, 7 flushing chambers, 8 rear pump covers, 9 are replaced Change block, 91 arc-shapeds projection, 10 annular recess.
Embodiment
The embodiment provided below in conjunction with accompanying drawing 1 to 2, further illustrates embodiment of the present utility model.This reality The following description is not limited to new.
As shown in Figure 1-2:A kind of low Pulp pump of flushing water pressure, including pump shaft 1 and the impeller 2 that is connected with pump shaft 1, Pump shaft 1 is arranged on bracing strut 3 and is connected by axle sleeve with bracing strut 3, and impeller 2 is arranged in pump case, be provided with pump case into Liquid mouthful and liquid outlet, are provided with filler 4, seal cage 5 and spacer 6, seal cage 5, spacer 6, rear pump between axle sleeve and bracing strut 3 It is provided with the flushing chamber 7 constituted between lid 8 and impeller 2, pump case and is provided with connection on flushing water inlet, seal cage 5 and is flushed into It is provided with fixing groove, fixing groove and sets with respect to place with impeller 2 on the mouth of a river and the internal flow channel for rinsing chamber 7, the rear pump cover 8 of pump case There is replacement block 9, replacement block 9 is fixedly connected by bolt with rear pump cover 8;
Cross section is provided with for semicircular annular recess 10 with respect to place with impeller 2 on rear pump cover 8, and replacement block 9 is located at punching Wash chamber 7 anterior, annular recess 10, which is located at, rinses the rear portion of chamber 7;To rinse chamber 7 close to liquid outlet part as front portion, principle liquid outlet Part is rear portion.
The arc-shaped being provided with the side relative with impeller 2 of replacement block 9 between multiple rows of arc-shaped projection 91, adjacent row is convex Rise 91 relative to the side wall of replacement block 9 height of projection differ 2-5mm;Further, the height alternative expression of arc-shaped projection 91 is set It is placed on the side wall of replacement block 9.Slurry in pump case, which enters, to be rinsed after chamber 7, first by the cavity between replacement block 9 and impeller 2, The passage of continuous reducing is formed between arc-shaped projection 91 and impeller 2 so that the pressure of slurry declines, and eventually passes annular recess 10, further the pressure of reduction slurry, so that the slurry pressure rinsed in chamber 7 declines, reduces the demand of washing pressure.
In order to further improve the anticorrosive degree of replacement block 9, replacement block 9 uses erosion-resisting plastic cement material or alloy material Matter.Relative to monolithic devices side wall, use cost is which reduced.
The utility model can effectively reduce the pressure rinsed during slurry pump operation in chamber 7, so as to reduce washing pressure.Separately Outside, rear pump cover 8 replaces the inwall of rear pump cover 8 to be contacted with rinsing the liquid in chamber 7 with respect to place with impeller 2 by replacement block 9, for a long time After use, replacement block 9 is corroded by granule foreign, can ensure that Pulp pump runs well by changing replacement block 9, effectively improve slag The service life of stock pump.
