Abstract
Disclosed is a stainless steel punching pump which is heat resistance and pressure resistance and is about the improvement of the shape of the impeller of the punching pump. Flange edges are arranged on both sides of the impeller. The two flange edges are arranged in the gap of the pump body, avoiding the radial shift of the pump shaft when the pump is in use, eliminating the radial force and reducing the radial load of the bearing so that the stability and the service life of the pump are improved; meanwhile, through holes are arranged on each vane of the impeller to improve the service life of the mechanical seal so that the liquid pressure between the impeller and the mechanical seal is greatly reduced and the abrasion of the mechanical seal is reduced.
Description
Technical field: the utility model relates to a kind of punching press pump, relates in particular to a kind of stainless steel heatproof, withstand voltage punching press pump.
Background technique: stainless steel heatproof, withstand voltage punching press pump are widely used in industries such as food, chemical industry, power plant.At present, there are following defective in the stainless steel heatproof that is adopted on the market, withstand voltage punching press pump: the pump chamber internal pressure is big during running, and is big to the mechanical seal wearing and tearing, causes leakage phenomenon easily; Because pump produces certain axial force in operation process, strengthened the axial load of bearing simultaneously, made stability, operating reliability and the withstand voltage degree of entire pump be subjected to certain influence.
Technology contents: the purpose of this utility model is exactly to adopt a kind of novel blade wheel structure, reduces leakage rate, improves volumetric efficiency, eliminated axial force, alleviate the axial load of bearing, improve stability and withstand voltage degree, is greatly improved the working life of pump.
The purpose of this utility model is achieved in that a kind of stainless steel heatproof, withstand voltage punching press pump partly be made up of the pump housing, carriage, pump shaft, impeller, mechanical seal etc., pump shaft by Bearing Installation on carriage, one end of pump shaft is sleeved in the pump housing by mechanical seal, carriage is fixed on the pump housing, and impeller is fixed on the pump shaft by impeller nut; It is characterized in that: a flange edge is respectively arranged in described impeller both sides, this flange edge just in time falls into the space of the pump housing, in the pump using process, can prevent also that by this a pair of flange edge pump shaft from moving forward and backward, eliminate axial force, alleviate the axial load of bearing, improve the stability and the working life of entire pump, simultaneously in order to alleviate in the pump using process pressure to mechanical seal, on each blade of impeller, respectively open a through hole, fluid pressure between impeller and the mechanical seal is reduced, alleviated wearing and tearing, improved the working life of mechanical seal mechanical seal.
In addition, in order to eliminate impeller nut loosening phenomenon in the pump operation process, on pump shaft, add again one with the opposite impeller nut of last impeller nut rotation direction, so just can improve the operating reliability of pump.
Description of drawings: Fig. 1 is the described a kind of stainless steel heatproof of model utility, withstand voltage punching press pump
1. impeller nut I 2. impeller nut II 3. pump housings 4. mechanical seals
5. carriage 6. pump shafts 7. bearings 8. flange edges
9. impeller 10. through holes
Embodiment: as can be seen from Figure 1, a kind of stainless steel heatproof described in the utility model, withstand voltage punching press pump are made up of the pump housing 3, carriage 5, pump shaft 6, impeller 9, mechanical seal 4, pump shaft 6 is installed in the carriage 5 by bearing 7, one end of pump shaft 6 is sleeved in the pump housing 3 by mechanical seal 4, carriage 5 is fixed on the pump housing 3, and impeller 9 is fixed on the pump shaft by impeller nut I1; It is characterized in that: in the both sides of described impeller 9 flange edge 8 is arranged respectively, this just in time falls into the space of the pump housing 3 to flange edge 8, during use, can prevent that pump shaft 6 from moving forward and backward, eliminate axial force, alleviate the axial load of bearing, improve the stability and the working life of entire pump; Simultaneously,, on each blade of impeller 9, respectively have a through hole 10, the fluid pressure between impeller 9 and the mechanical seal 4 is reduced greatly, alleviate wearing and tearing mechanical seal in order to improve the working life of mechanical seal 4; In addition, become flexible phenomenon, on pump shaft 6, add an impeller nut II2 opposite again, can improve the operating reliability of pump like this with impeller nut I1 rotation direction in order to prevent impeller nut I1.
