Description
Technical field
The utility model is related to a kind of centrifugal pump, and in particular to a kind of No leakage centrifugal pump.
Background technology
Traditional centrifugal pump contains only running wheel and mechanical seal or packing seal, and packing seal is when running one section
Between or spent running-in period and will result in leakage, mechanical seal will also result in leakage using a period of time.Improve the maintenance of pump frequently
Rate and maintenance cost.
The content of the invention
The purpose of this utility model is the No leakage centrifugal pump for providing a kind of good seal performance.
The technical scheme that the utility model is taken is:
A kind of No leakage centrifugal pump, including pump case, pump case are provided with delivery port and water inlet, rotating shaft are provided with pump case,
The inserting end end of rotating shaft is provided with running wheel, and pump cover is provided with the end face of pump case side, and rotating shaft is worn and connects pump cover, in rotating shaft
Axle sleeve is cased with, labyrinth seal and oil sealing is sequentially installed between axle sleeve and pump cover inner hole wall from inside to outside, pacified on the outer face of end cap
Equipped with oil sealing cover, oil sealing cover extruding oil sealing is provided with sealing impeller between the running wheel and pump cover, sealing impeller is fixed
It is installed on rotating shaft.
After taking above technical scheme, the beneficial effects of the utility model are：Pump operationally, due to sealing impeller it is same
Step rotation, produces with after the same pressure of running wheel, the pressure of pump generation is just balanced, simultaneously because the effect of labyrinth seal
The possibility that pumped (conveying) medium flows to annular seal space is avoided, when out of service, now pump is in and needs static seal state pump, then installs additional
After oil sealing, it is ensured that the possibility of liquid No leakage, so as to ensure that the stable operation of equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Specific embodiment of the present utility model is further described below in conjunction with accompanying drawing
As illustrated, a kind of No leakage centrifugal pump, including pump case 1, pump case 1 is provided with delivery port 2 and water inlet 3, pump case 1
Rotating shaft 4 is inside installed, the inserting end end of rotating shaft 4 is provided with running wheel 5, pump cover 6 is provided with the end face of the side of pump case 1,
Rotating shaft 4 is worn and connects pump cover 6, and axle sleeve 7 is cased with rotating shaft 4, and it is close to be sequentially installed with labyrinth from inside to outside between axle sleeve 7 and the inner hole wall of end cap 1
Envelope 8 and oil sealing 9, are provided with oil sealing cover 10, the extruding oil sealing 9 of oil sealing cover 10, the running wheel 5 on the outer face of pump cover 6
Sealing impeller 11 is provided with between pump cover 6, sealing impeller 11 is fixedly installed in rotating shaft 4.
