The problem of in terms of pumped (conveying) medium.Pumped (conveying) medium includes media type, for the temperature of pumped (conveying) medium, the conveying pair of high-temperature medium
More stringent requirements are proposed for structure, material and the auxiliary system of chemical pump.
When pump operation, medium is full of pump chamber, by installing gland seal device in the shaft seal cavity of pump cover, gland seal device play by
Media isolation in pump chamber and prevent air enter effect.It is lower than 120 DEG C of medium for temperature, pump is usually not provided with special
Cooling system carry out cooling medium, mostly use medium itself to lubricate and cool down；For temperature within 80 DEG C or more, 120 DEG C
Medium, since one end of pump shaft is protruded into pump chamber, the other end of pump shaft is directly contacted with motor shaft, higher medium temperature meeting
It is transmitted to motor bearings by pump shaft and motor shaft, motor bearings is under such working environment for a long time and can be destroyed, most
The baneful influences such as motor burning, pump damage are caused eventually.
Utility model content
In view of the deficiencies of the prior art, the utility model discloses the pump shafts with fan coolling structure.
Technical solution used by the utility model is as follows:
A kind of pump shaft with fan coolling structure, pump include the pump housing, impeller, pump cover, motor connection frame, motor and pump shaft；
Pump cover is fixed on the side of the pump housing；Cavity between the pump housing and pump cover is pump chamber；Impeller is mounted in the pump chamber；Impeller is fixed
In one end of pump shaft；Motor connection frame is fixed on the side of pump cover；Motor shaft protrudes into motor connection frame；Motor is fixed on motor company
Connect the side of frame；Pump shaft is stretched out from the pump chamber, protrudes into motor connection frame；Pump shaft is connected to one by shaft coupling and motor shaft
It rises；Shaft seal cavity is opened up at pump cover；Gland seal device is mounted in the shaft seal cavity, and pump shaft includes the outer rim that a circle is protruded to periphery；
One end with outer rim of the pump shaft and motor axis connection；Multiple fan grooves are opened up in the outer rim；Multiple fan grooves are with circumference
Form is equal away from distribution in outer rim.
Its further technical characteristic are as follows: the central angle angle of the fan groove is 30 °；The two neighboring fan groove it
Between angle be 60 °.
Its further technical characteristic are as follows: the gland seal device is mechanical seal.
The beneficial effects of the utility model are as follows:
1, multiple fan grooves are opened up, the contact area of pump shaft and motor shaft is on the one hand reduced, reduce the transmitting of heat；
The part of unslotted forms the blade construction of fan with the part for opening up multiple fan grooves on another aspect pump shaft, plays cooling
Effect rotates in pump operation process with pump shaft, and fan coolling structure drives the surrounding air flowing of pump shaft, reduces pump shaft
Transmitting temperature.
2, by effectively combining the fan cooled down and pump shaft, the pump with the structure is suitable for high-temperature medium occasion,
Maximum temperature greatly reduces a possibility that medium temperature damages motor bearings by the transmitting of pump shaft up to 120 DEG C,
Dramatically protect the normal operation of motor and pump.
