Abstract
The utility model relates to a water pump seal field specifically is a self -align seal structure of water pump vane, and it includes impeller (1), the outside of impeller (1) offer flutedly on the surface, and the outside surface of impeller (1) has cup jointed rather than complex sealing ring (2), and be provided with on the inboard surface of sealing ring (2) with recess complex lug (3), the utility model aims at providing a self -align seal structure of water pump vane, the specific structures through impeller and sealing ring makes impeller and the sealed bad location of mutually supporting, at the water pump operation in -process, can ensure all the time that the sealing ring does not drop, and then ensure that the impeller is not damaged, very big improvement the working condition and the life of pump.
Description
Technical field
This utility model relates to water pump packing field, is specially a kind of water pump vane self-align sealing structure.
Background technology
Water pump is a kind of a kind of Hydraulic Elements that low-pressure medium is changed into high-pressure medium, accordingly, it would be desirable to good sealing, and the sealing of impeller is a pith of water pump packing.
Existing water pump vane seals and mostly uses sealing ring to seal, and in the various operation of water pump, when pump head is bigger, easily occurs that sealing ring comes off, the problem damaging impeller；Existing water pump gland ring typically uses axial junction of the edges of two sheets of paper screw to position, on the one hand, easily loosens due to reasons such as vibrations in operation, comes off.On the other hand screw size is limited, time high-lift, is not enough to bear downward thrust；It addition, screw location, when the impeller the biggest for special substance hardness or sealing ring, it is impossible to tapping, it is impossible to be suitable for；The tightening of sealing ring, is directly connected to operation stability and the reliability of long-shaft pump, even determines working condition and the service life of whole pump.
Utility model content
The purpose of this utility model is to provide a kind of water pump vane self-align sealing structure, make impeller by the ad hoc structure of impeller and sealing ring and seal the bad location that cooperates, during water pump operation, can guarantee that sealing ring does not falls off all the time, and then guarantee that impeller is not damaged by, greatly improve working condition and the service life of pump.
In order to realize object above, the technical solution adopted in the utility model is: a kind of water pump vane self-align sealing structure, it includes impeller (1), groove is offered on the outer surface of described impeller (1), and the outer surface of impeller (1) is socketed with the sealing ring (2) coordinated with it, and on the inner surface of sealing ring (2), it is provided with the projection (3) with groove fit.
Further, described impeller (1) left part external diameter is less than right part external diameter, and the left part of the left part of impeller (1) and sealing ring (2) is matched in clearance, and the right part of impeller (1) is interference fit with the right part of sealing ring (2).
Further, for inclined-plane on the right side of the groove that described impeller (1) outer surface is offered, and gradient is 30-45 °.
Further, described impeller (1) outer surface offers uniformly no less than three grooves.
Further, described bottom portion of groove is provided with compression blocks (4), and described compression blocks (4) is encapsulant, and in the case of normal assembling, compression blocks (4) is in compressive state.
The beneficial effects of the utility model are:
1, make impeller by the ad hoc structure of impeller and sealing ring and seal the bad location that cooperates, during water pump operation, it is possible to guarantee that sealing ring does not falls off all the time, and then guarantee that impeller is not damaged by, greatly improving working condition and the service life of pump.
2, impeller left part external diameter is less than right part external diameter, the left part of impeller and the left part of sealing ring are matched in clearance, the right part of impeller and the right part of sealing ring are interference fit, greatly facilitate the heat installation of sealing ring, make projection can be good at being installed in groove, ensure that again good sealing effectiveness simultaneously.
3, the design on inclined-plane on the right side of groove, determines the right side of projection and should also be as inclined-plane, and then facilitates projection and can load in groove from left to right.
4, the quantitative design of groove, can well ensure impeller operation when, and impeller and sealing ring will not produce relative motion, and then ensure impeller and the sealing effectiveness of sealing ring.
5, the design of compression blocks, can be formed with projection and seal position, improve the effect sealed further.
