Description
Technical field
This utility model relates to a kind of centrifugal pump technical field, is specially a kind of chemical crystallization centrifugal pump.
Background technology
At present, existing chemical centrifugal pump is made up of motor and pump two parts, and pump and motor use associated mode to couple, and typical structure is mainly made up of parts such as motor, axle, connecting cap, mechanical seal, impeller, the pump housings.It is not difficult to find out, when existing structure conveying has easy crystallinity medium, when pump is out of service, residual dielectric will crystallize and be attached on mechanical sealing linkage ring and stationary ring face, next time again start shooting use time, due to crystallization exist, cause mechanical sealing surface to destroy, sealing effectiveness is deteriorated, and makes mechanical seal lifetime simultaneously.
The problem that the above-mentioned technical staff of being needs to solve.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of chemical crystallization centrifugal pump, and it brings improvement greatly to the sealing of pump, and the sealing making pump is more reliable, and in the service life that prolonged mechanical seals, its main technical scheme is as follows:
A kind of chemical crystallization centrifugal pump, comprising:
Motor (1), the outfan of described motor (1) main shaft connects pump shaft (2)；
The pump housing (6) arranged along pump shaft (2) axially extending direction, the described pump housing (6) forms intake tunnel (8) and the impeller installation cavity of serpentine, it is provided with exhalant canal (9) in the left side of the pump housing (6), described exhalant canal (9) and intake tunnel (8) are respectively equipped with plug wire (12)；
The connecting cap (3) being located between motor (1) and the pump housing (6), the two ends of described connecting cap (3) form respectively and radially extend the mounting seat (301) that power supply machine (1) is installed and the connecting portion (302) connecting the pump housing (6)；
The impeller (5) being installed in impeller installation cavity, described impeller (5) is fixed with the free end extending to the pump housing (6) interior pump shaft (2) by flat key structure (10)；
Wherein, the pump shaft (2) at described connecting cap (3) place is provided with mechanical seal (4), the sidewall of described mechanical seal (4) correspondence position connecting cap (3) is provided with the shower nozzle (7) of accessible connecting cap (3) inner side, and described shower nozzle (7) extends to the free end connection in the pump housing (6) outside extension tube attached (11).
Further, the water inlet end of described extension tube attached (11) is provided with valve mechanism.
Further, the lateral wall on described connecting portion (302) the correspondence position pump housing (6) top forms carrier (601).
This practicality provides the benefit that: the sidewall of connecting cap is provided with shower nozzle, shower nozzle connects extension tube attached, when water pump stops, by extension tube attached, clear water with pressure can be accessed, continuously to mechanical seal rinsing, the crystallinity medium remaining in mechanical seal is made all to wash, so that it is guaranteed that sealing effectiveness, the service life that prolonged mechanical seals.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of chemical crystallization centrifugal pump in embodiment.
Detailed description of the invention
In order to make the technological means of this practicality, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this practicality is expanded on further.
Seeing Fig. 1, a kind of chemical crystallization centrifugal pump, it is made up of motor 1, the pump housing 6, connecting cap 3 and impeller 5, and the outfan of motor 1 main shaft connects pump shaft 2；The pump housing 6 arranges along the axially extending direction of pump shaft 2 and forms intake tunnel 8 and the impeller installation cavity of serpentine, is provided with exhalant canal 9 in the left side of the pump housing 6, exhalant canal 9 and intake tunnel 8 are respectively equipped with plug wire 12；Connecting cap 3 is then located between motor 1 with the pump housing 6 and its two ends form respectively and radially extend the mounting seat 301 that power supply machine 1 is installed and the connecting portion 302 being connected the pump housing 6；Need explanation, mounting seat 301 is provided with the through hole coaxial with motor cabinet 101 installing hole, has bolt I along through hole and installing hole are axial arranged, is fixed with connecting cap 3 by motor 1 by nut I, impeller 5 is installed in impeller installation cavity, and impeller is fixed by the free end of flat key structure 10 with pump shaft 2；Wherein, the pump shaft 2 at connecting cap 3 is provided with mechanical seal 4, and the sidewall of mechanical seal 4 correspondence position connecting cap is provided with the shower nozzle 7 inside accessible connecting cap 3, and the free end connection that shower nozzle 7 extends to outside the pump housing has extension tube attached 11.
In order to reach ideal control effect, the water inlet end of extension tube attached 11 is provided with valve mechanism.
For ease of fixing, the lateral wall on the connecting portion 302 correspondence position pump housing 6 top forms carrier 601, and carrier 601 is provided with coaxial through hole with connecting portion 302, is disposed with bolt II along through hole, can be fixed with the pump housing 6 by connecting cap 3 by nut II.
When water pump stops, by extension tube attached 11, clear water with pressure can being accessed, continuously mechanical seal 4 be rinsed, make the crystallinity medium remaining in mechanical seal 4 all wash, so that it is guaranteed that sealing effectiveness, the service life that prolonged mechanical seals.
