Description
Technical field
The utility model relates to impellers, and in particular to a kind of band position detecting function centrifugation impeller of pump.
Background technique
Impeller is component important in centrifugal pump, and transmission shaft transfers torque to impeller and impeller is rotated, and impeller is in high speed
By changing the conveying for pumping intracorporal pressure to realize fluid when rotation.Since centrifugal pump can generate biggish shake at runtime
Dynamic, damage situations can occur in rotary course for impeller.Impaired most of impeller is that occur in rotary course due to impeller
The problem of more than its normal range of operation, but centrifugation impeller of pump in the prior art detects impeller without what means and exists
It is no in rotary course to have the case where beyond normal range of operation, it is all just discovery out of joint, there are security risks.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of band position detecting function centrifugal pump use
Impeller, described band position detecting function centrifugation its structure of impeller of pump is simple, compact, reasonable, matches with matched transmission shaft structure
It closes and uses, can detect in time whether centrifugal pump impeller exceeds normal range of operation, discovery eliminates safe hidden trouble in advance.
According to technical solution provided by the utility model, a kind of band position detecting function centrifugation impeller of pump, the band position
Setting detection function centrifugation impeller of pump includes impeller body, is equipped with blade circumferentially-spacedly along its on the impeller body；Impeller
The centre of ontology offers axis hole, and convex key is formed on the inner surface of the axis hole, and the convex key is equipped with magnet.
Further, the blade includes internal lobe and siphonal lobe；It offers and leads circumferentially-spacedly along its on the impeller body
Chute, the internal lobe and siphonal lobe are respectively arranged on inside and outside diversion trench at marginal position, and the internal lobe and siphonal lobe are to impeller
Ontology it is axially extending.
Further, the groove width of the diversion trench is gradually increased by its front end to rear end.
Further, in the diversion trench be equipped with inclined deflector, the two sides of the deflector respectively with internal lobe and outside
Leaf is linked together；The deflector gradually tilts upwards on from the front end of diversion trench to the direction of its rear end.
It is and existing from the above as can be seen that band position detecting function provided by the utility model is centrifuged impeller of pump
Technology is compared to having following advantages: described band position detecting function centrifugation its structure of impeller of pump is simple, compact, reasonable, and matches
The transmission shaft structure of set is used cooperatively, and can be detected in time whether centrifugal pump impeller exceeds normal range of operation, be found in advance
It eliminates safe hidden trouble.

Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below in conjunction with specific embodiment, and
Referring to attached drawing, the utility model is further described.Wherein identical components are presented with like reference characters.It needs
Illustrate, word "front", "rear" used in the following description, "left", "right", "up" and "down" refer to the side in attached drawing
To.The word "inner" used and "outside" refer respectively to the direction towards or away from geometric center of specific component.
A kind of band position detecting function centrifugation impeller of pump, as shown in Fig. 1 ~ Fig. 4, the band position detecting function centrifugal pump
Include: with impeller
Impeller body 1 offers diversion trench 7 along its on the impeller body 1 circumferentially-spacedly, is located at the impeller body
Internal lobe 5 and siphonal lobe 6 are respectively equipped with inside and outside 1 front diversion trench 7 at marginal position, the internal lobe 5 and siphonal lobe 6 are to impeller
Ontology 1 it is axially extending；The centre of impeller body 1 offers axis hole 2, forms convex key 3, convex key 3 on the inner surface of the axis hole 2
It is equipped with magnet 4.
Flow velocity when in order to improve fluid by the diversion trench 7, the groove width of the diversion trench 7 by its front end to rear end by
It is cumulative big, and inclined deflector 8 is equipped in the diversion trench 7, the two sides of the deflector 8 respectively with internal lobe 5 and siphonal lobe 6
It is linked together, the deflector 8 gradually inclination upwards on from the front end of diversion trench 7 to the direction of its rear end.When impeller body 1 revolves
When turning, the deflector 8 at 7 front position of diversion trench first limits fluid feed channel, applies certain pressure to fluid, so that fluid
It can be quickly through diversion trench 7.
When concrete application, transmission shaft and the impeller body 1 cooperate, the outer surface of transmission shaft be equipped with it is convex on axis hole 2
The keyway that key 3 matches is additionally provided with block in the keyway, and the transmission shaft is equipped with twice loop coil, and block is located at two
The outside of a road loop coil wherein loop coil.Transmission shaft passes through the axis hole 2 of the impeller body 1, so that impeller body 1
Side is stuck at stop location, and then the transmission shaft of the other side of impeller body 1 installs fixing sleeve, so that impeller body 1 be limited
It is scheduled on transmission shaft between twice loop coil.Magnet 4 when impeller body 1 is in normal range of operation, on impeller body 1
Between twice loop coil.
The utility model is arranged on the transmission shaft of corresponding matching by the 2 insert magnet 4 of axis hole on impeller body 1
Loop coil, in use, the lead-out wire of loop coil is connect with current detector, when impeller body 1 exceeds normal range of operation
When, magnet 4 can generate electric current and be detected by current detector, current detector can record information to by loop coil
In the car running computer of automobile and alarm signal is issued, so as to find to eliminate safe hidden trouble in advance.
It should be understood by those ordinary skilled in the art that: the foregoing is merely specific embodiment of the utility model and
