Description
Technical field
This utility model relates to pump field, specifically a kind of centrifugal pump.
Background technology
Centrifugal pump be a kind of centrifugal force produced when relying on impeller to rotate to carry the pump of liquid, utilize the impeller blade of high speed rotating to drive liquid to rotate, liquid thrown away, thus reaches the purpose of conveying.Before centrifugal pump starts, it is necessary to hydraulically full in making pump case and inlet tube, then start motor, make pump shaft impeller and liquid at high speed rotary motion, liquid generation centrifugal motion, be thrown toward impeller outer edge, through the export pipeline of the runner inflow centrifugal pump of volute pump case.It is widely used in: wine brewing, beverage, milk deli, biological medicine industry.
The mechanical seal pressurized of existing centrifugal pump is uneven, therefore suffers from abrasion condition serious, needs to be improved this.
Utility model content
The purpose of this utility model is to provide a kind of centrifugal pump, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of centrifugal pump, including motor, every dish, impeller, pump shaft, machine envelope O, machine envelope carborundum, spring, positioning sleeve and pump head, the output shaft of described motor is in transmission connection pump shaft, impeller head end is enclosed within the end of pump shaft, and impeller head end is bolted to connection pump the tip of the axis, it is also equipped with on pump shaft every dish, positioning sleeve fixed cover is on pump shaft, machine envelope carborundum is located at impeller head end and every Pan Anzhuanjianxichu, and spring is located between machine envelope carborundum and positioning sleeve, utilize spring for the machine envelope lasting pressure of carborundum；Described machine envelope O is located between machine envelope carborundum and impeller head end, carborundum is sealed now by spring continuous extrusion machine, and pressure is persistently passed to machine envelope O by machine envelope carborundum, so make machine envelope O can pressurized continually and steadily, thus enhance overall sealing performance.
As further program of the utility model: described positioning sleeve uses metal material to make.
Compared with prior art, the beneficial effects of the utility model are: this utility model spring is the pressure that machine envelope carborundum is lasting, locating sleeve structure is installed simultaneously, therefore pressure is persistently passed to machine envelope O by machine envelope carborundum, so make machine envelope O can pressurized continually and steadily, thus enhance overall sealing performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of centrifugal pump of this utility model.
In figure: 1-is every dish, 2-impeller, 3-pump shaft, 4-machine envelope O, 5-machine envelope carborundum, 6-spring, 7-positioning sleeve, 8-pump head.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of centrifugal pump, including motor, every dish 1, impeller 2, pump shaft 3, machine envelope O 4, machine envelope carborundum 5, spring 6, positioning sleeve 7 and pump head 8, the output shaft of described motor is in transmission connection pump shaft 3, impeller 2 head end is enclosed within the end of pump shaft 3, and impeller 2 head end is bolted to connection the end of pump shaft 3, it is also equipped with on pump shaft 3 every dish 1, positioning sleeve 7 fixed cover is on pump shaft 3, machine envelope carborundum 5 is located at impeller 2 head end and at dish 1 assemblage gap, and spring 6 be located at machine envelope carborundum 5 and positioning sleeve 7 between, spring 6 is utilized to seal, for machine, the pressure that carborundum 5 is lasting；Described machine envelope O 4 is located between machine envelope carborundum 5 and impeller 2 head end, carborundum 5 is sealed now by spring 6 continuous extrusion machine, and pressure is persistently passed to machine envelope O 4 by machine envelope carborundum 5, so make machine envelope O 4 can pressurized continually and steadily, thus enhance overall sealing performance.
Described positioning sleeve 7 uses metal material to make.
Operation principle of the present utility model is: positioning sleeve 7 fixed cover is on pump shaft 3, and machine envelope carborundum 5 is located at impeller 2 head end and at dish 1 assemblage gap, and spring 6 is located between machine envelope carborundum 5 and positioning sleeve 7, utilizes spring 6 to seal, for machine, the pressure that carborundum 5 is lasting；Described machine envelope O 4 is located between machine envelope carborundum 5 and impeller 2 head end, carborundum 5 is sealed now by spring 6 continuous extrusion machine, and pressure is persistently passed to machine envelope O 4 by machine envelope carborundum 5, so make machine envelope O 4 can pressurized continually and steadily, thus enhance overall sealing performance.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
