Abstract
The utility model belongs to the technical field of water pumps, and particularly relates to a sewage pump spindle, wherein a wear-resisting sleeve fixed on a spindle is sheathed on the cylinder cover installation position at the lower part of the spindle; in the utility model, a ceramic ring is closely matched with the spindle and is fixedly arranged on the spindle by glue, a framework oil seal is arranged outside the spindle, and as the hardness of the ceramic ring is high, the spindle can not destroy the tightness between the framework oil seal and the ceramic ring due to friction between the spindle and the framework oil seal when the spindle rotates at high speed, therefore, water is effectively prevented from entering the motor; the sewage pump spindle has simple structure, is convenient to install and good in wear-resisting effect, greatly improves the quality of the water pump and prolongs the service life of the water pump, reduces the use cost, and is applicable to various pumps with framework seals.
Description
Technical field
The utility model belongs to the pump technology field, refers in particular to a kind of sewage pump rotating shaft.
Background technique
Along with the progress of society, water pump has obtained very big popularization and application in productive life.As sewage pump, along with the reinforcement with environmental consciousness of improving constantly of people's living standard, sewage pump is familiar with by people, and it is more and more broader that application area also becomes.The sealing configuration of the rotating shaft of existing sewage pump is: the place, grease chamber at pump is provided with double mechanical seal, being provided with outside framework oil seal between rotating shaft and oil cylinder cover realizes, during sewage pump work, outside framework oil seal is a transfixion, rotating shaft is rotated, because rotating shaft is high speed rotating under the drive of motor at work, friction between outside framework oil seal and the rotating shaft, in rotating shaft, grind groove easily, make to have the gap between outside framework oil seal and the rotating shaft, reduced the sealing of outside framework oil seal, because foreign material are more in the sewage, impurity in the sewage enters by the groove that grinds in the rotating shaft easily and destroys mechanical seal in the grease chamber, thereby mechanical seal was lost efficacy, cause the motor water inlet and damage, thereby make the sewage pump can't proper functioning, influence working efficiency, reduced the quality and the working life of sewage pump, improved the user cost of sewage pump, brought a series of inconvenience to productive life, the pump series products that seals at some other use outside framework oil seal also exists identical problem equally.
Summary of the invention
The purpose of this utility model provides a kind of sewage pump rotating shaft of simple in structure, easy for installation, wear-resisting, good sealing effect.
The utility model is achieved in that
The sewage pump rotating shaft, the oil cylinder cover installation position of rotating shaft bottom is provided with the wear-resistant sleeve installation position, is arranged with the wear-resistant sleeve that is fixed in the rotating shaft on the wear-resistant sleeve installation position.
Above-mentioned wear-resistant sleeve is a porcelain ring, also can be the wear-resistant sleeve that the higher material of other hardness is made.
The internal diameter of above-mentioned wear-resistant sleeve matches with the external diameter of rotating shaft and be provided with glue layer between wear-resistant sleeve and rotating shaft.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model closely cooperates porcelain ring and rotating shaft, and be fixed by glue and be arranged in the rotating shaft, outside framework oil seal is set outside rotating shaft, because the hardness height of porcelain ring, under the situation of rotating shaft high speed rotating, also not can because of and outside framework oil seal between friction and destroy sealing between outside framework oil seal and the porcelain ring, prevent that effectively fine sand, tiny impurity from entering damaged mechanical seal in the grease chamber of pump, thereby make the mechanical water pump seal failure can't proper functioning;
2, the utility model is simple in structure, and is easy for installation, wear-resisting effective, improved the quality and the working life of water pump greatly, reduced user cost;
3, the utility model is applicable on the various pumps that have a reinforced seal.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cross-sectional view that the utility model uses on sewage pump;
Fig. 3 is the A portion enlarged diagram of Fig. 2.
Embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 1-3:
The sewage pump rotating shaft, the oil cylinder cover installation position of rotating shaft 10 bottoms is provided with the wear-resistant sleeve installation position, is arranged with the wear-resistant sleeve 70 that is fixed in the rotating shaft on the wear-resistant sleeve installation position.
Above-mentioned wear-resistant sleeve 70 is a porcelain ring.
The internal diameter of above-mentioned wear-resistant sleeve 70 matches with the external diameter of rotating shaft 10 and be provided with glue layer between wear-resistant sleeve 70 and rotating shaft 10.
Use condition on sewage pump of the present utility model:
Rotating shaft 10 is motor shaft, one end 101 of rotating shaft 10 connects rotor 201, the other end of rotating shaft is connected with impeller 80, between motor 20 and impeller 80, outside the rotating shaft 10, be disposed with grease chamber 30 and oil cylinder cover 40, between grease chamber 30 and rotating shaft 10, be provided with mechanical seal 50, between oil cylinder cover 40 and rotating shaft 10, be provided with outside framework oil seal 60, fix and seal the wear-resistant sleeve 70 that is arranged in the rotating shaft 10 being arranged between rotating shaft 10 and the outside framework oil seal 60 by glue, outside framework oil seal 60 is fixedly installed on the oil cylinder cover 40; When rotating shaft 10 is rotated, ceramic jacket rotates with rotating shaft 10, because the hardness of ceramic jacket is higher, wear-resisting effective, in running up, can better tightness polishing scratch not appear, because of the effect of outside framework oil seal 60, the effect that has solved because of outside framework oil seal 60 countershafts 10 causes the gap occurring in the rotating shaft 10, has reduced sealing effect and makes the mechanical water pump seal failure can't proper functioning.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
