Abstract
The utility model relates to the technical field of autoclaved concrete aerated block production, in particular relates to a slurry pump with a replaceable shaft head, and mainly comprises a motor, a shaft joint, a main shaft, a pump case, an impeller and a fixed support, wherein the motor, the main shaft and the pump case are fixedly installed into a whole through the fixed support; the pump case is provided with an open pore; the main shaft also comprises a bushing; the front end of the main shaft is cut into a thin shaft part; the thin shaft part is coaxial with the main shaft; the bushing is installed on the thin shaft part of the main shaft; one end of the main shaft and is assembled with the motor through the shaft joint; the thin shaft part of the main shaft is sleeved with the bushing and then assembled with the impeller; the impeller is held in the pump case; the bushing is held in the open pore of the pump case. The slurry pump disclosed by the utility model has the beneficial effects of wear resistance, reduced production cost and convenience in maintenance.
Description
Technical field:
The utility model relates to steam pressure autoclaved lightweight concrete production technical field, particularly a kind of spindle nose Changable type shurry pump.
Background technique:
In autoclave aerated concrete building block is produced; The conveying of pulverized fuel ash slip is a groundwork; As shown in Figure 1; Shurry pump mainly comprises motor 91; Main shaft 92; Pump case 93 and impeller 94; Main shaft 92 1 ends and motor 91 assemblings; The other end of main shaft 92 and impeller 94 assemblings; Impeller 94 is contained in pump case 93; Due to shurry pump in carrying the process of slip; Pump case 93 and impeller 94 are positioned in slip; Because main shaft needs the impeller rotation; So have certain gap between when pump case 93 coordinates assembling with main shaft 92; Slip produces friction with main shaft 92 after entering this gap; And the degree of wearing and tearing is very large; A shurry pump main shaft 92 is scrapped with regard to substantially reaching through the use of a year; Must change and normally to use.
The shurry pump main shaft is the major part of shurry pump, and because rotating speed is high, concentricity and coaxality precision prescribed are high, can not welding repair processing after wearing and tearing, can only change axle or equipment scrapping.
Summary of the invention:
The utility model is providing a kind of spindle nose Changable type shurry pump, the defective that exists to solve above-mentioned prior art.
The technical solution of the utility model is: spindle nose Changable type shurry pump mainly comprises motor; Coupling; Main shaft; Pump case; Impeller and fixed support; Fixed support is with motor; Main shaft and pump case fixed installation are integrated; Pump case arranges perforate; Main shaft also comprises axle sleeve; The front end cutting of main shaft forms thin axial region; This thin axial region and main shaft concentric; Axle sleeve is installed on the thin axial region of main shaft; Main shaft one end is by coupling and motor assembling; Assemble with impeller again after the thin axial region socket axle sleeve of main shaft; Impeller is contained in pump case; Axle sleeve is contained in the perforate of pump case.
Due to axle sleeve being set on main shaft; So when the pump case of spindle nose Changable type shurry pump and impeller are positioned over when carrying slip in slip; Has certain gap between when pump case coordinates assembling with axle sleeve; Slip produces friction with axle sleeve after entering this gap; Prevent that slip is directly to spindle abrasion; Thereby extended the working life of main shaft; If axle sleeve wears up to a certain degree; Can install and use changing a direction after the axle sleeve dismounting; The rear replaceable axle sleeve if all wear and tear in the two end part of axle sleeve; Compare further with the replacing main shaft and reduce production costs; Assembling for convenience detach simultaneously; Easily maintenance.
Compared with prior art, the beneficial effects of the utility model are: the utlity model has wear-resistant and reduce production costs, the advantage of easy-maintaining.
Description of drawings:
Fig. 1 is prior art spindle nose Changable type structure of slurry pumps schematic diagram.
Fig. 2 is the utility model spindle nose Changable type structure of slurry pumps schematic diagram.
Fig. 3 is the pump case plan structure schematic diagram of the utility model spindle nose Changable type shurry pump.
In figure: motor 1, coupling 2, main shaft 3, axle sleeve 31, thin axial region 32, pump case 4, perforate 41, impeller 5, fixed support 6.
Embodiment:
Consult Fig. 2; Spindle nose Changable type shurry pump mainly comprises motor 1; Coupling 2; Main shaft 3; Pump case 4; Impeller 5 and fixed support 6; Fixed support 6 is with motor 1; Main shaft 3 and pump case 4 fixed installations are integrated; Pump case 4 arranges perforate 41; Main shaft 3 also comprises axle sleeve 31; The front end cutting of main shaft 3 forms thin axial region 32; This thin axial region 32 and main shaft 3 concentrics; Axle sleeve 31 is installed on the thin axial region 32 of main shaft 3; Main shaft 3 one ends are by coupling 2 and motor 1 assembling; Assemble with impeller 5 again after the thin axial region 32 socket axle sleeves 31 of main shaft 3; Impeller 5 is contained in pump case 4; Axle sleeve 31 is contained in the perforate 41 of pump case 4.
Due to axle sleeve 31 being installed on the thin axial region 32 of main shaft 3; Has certain gap between when pump case 4 coordinates assembling with axle sleeve 31; When the pump case 4 of spindle nose Changable type shurry pump and impeller 5 are positioned over when carrying slip in slip; Slip produces friction with axle sleeve 31 after entering this gap; Prevent that slip is directly to main shaft 3 wearing and tearing; Thereby extended the working life of main shaft 3; If axle sleeve 31 wears up to a certain degree; Can install and use changing a direction after axle sleeve 31 dismountings; The rear replaceable axle sleeve 31 if all wear and tear in the two end part of axle sleeve 31; Compare further with replacing main shaft 3 and reduce production costs; Disassembly and assembly simultaneously are convenient; Easily maintenance.
