Fig. 1 is the structural representation of a kind of modified model double suction pump of the present utility model.
Fig. 2 is the structural representation of the right-hand member drive end plain bearing element of Fig. 1 double suction pump.
Fig. 3 is the structural representation of the left end anti-drive end plain bearing element of Fig. 1 double suction pump.
Embodiment
Referring to Fig. 1 to Fig. 3, a kind of modified model double suction pump of the present utility model mainly is made up of the pump housing 1, pump cover 2, impeller 3, axle 4 and Sealing 5.
The pump housing 1 right-hand member is the drive end 6 of axle, and drive end plain bearing element 7 is housed, and drive end is supported by sliding bearing 71, and sliding bearing 71 is set in the body of sliding bearing 8, and sliding bearing sleeve 72 is installed on the axle 4 and rotates with axle.
The pump housing 1 left end is the anti-drive end 9 of axle, and anti-drive end plain bearing element 10 is housed, and anti-drive end is supported by sliding bearing 101, and sliding bearing 101 is set in the body of sliding bearing 11, and sliding bearing sleeve 102 is installed on the setting sleeve 103 and rotates with axle 4.Anti-drive end 9 ends are covered 12 shutoff with sliding bearing between the pump cover 2 and are connected by being installed in the pump housing 1.
Above-mentioned sliding bearing usable medium water flushing, lubricated.Sliding bearing and sliding bearing sleeve are made by stupalith or high-molecular organic material.
Impeller 3 is installed in 14 of drive end impeller sleeve 13 and anti-drive end impeller sleeves.Sealing 5 is installed on the drive end axle 4 by Sealing axle sleeve 51, and is pushed down by seal gland 52.Drive end Sealing 5 is by thrust ring 73 location that are installed on the axle 4.
The circlip for shaft 15 of location is housed on the anti-drive end axle 4, and fixing by two locking nuts 104.Between setting sleeve 103 and sliding bearing sleeve 102, be equipped with on the anti-drive end axle 4 and adjust ring 105, be used to adjust the axial float of axle 4.Side at sliding bearing sleeve 102 and sliding bearing 101 on the anti-drive end axle 4 is equipped with thrust ring 106.
Number in the figure 16 is drive end axle cover locking nuts, the 17th, and non-drive end axle cover locking nut, the 18th, seal ring, the 20th, flushing line.
This double suction pump can be controlled axial float.There is not axial force in double suction pump under perfect condition, but owing to reason is made in casting, processing etc., exist axial force inevitably, so pump the axial float phenomenon will occur in running.If axial force is pointed to drive end, whole axial drive end play, the effect of adjusting, buffering has been played in the gap between sliding bearing and thrust ring in the anti-drive end plain bearing element at this moment, can make the pump safe transition to stable operation.If axial force is pointed to anti-drive end, trend to the anti-drive end play appears in whole axle, and very close to each other between sliding bearing and the thrust ring in the drive end plain bearing element, but axial float can be regulated, be cushioned to Sealing, can make the pump safe transition to stable operation equally.
Working procedure of the present utility model is as follows:
Before the startup, full of liquid in the double suction pump, after the startup, impeller is constantly from suction chamber inspiration liquid, and under action of centrifugal force, the kinetic energy of liquid and pressure energy all have increase.Drive end all communicates with impeller inlet with a side of the sliding bearing of anti-drive end, be in low-pressure state, opposite side then links to each other with delivery chamber by pipeline, is in high pressure conditions, under normal operation, under the effect of pressure reduction, high pressure water flows to impeller inlet by 6～8 tanks of sliding bearing continuously, long-term lubricating bearings, and can take away the interior impurity of bearing, sliding bearing is in the good working environment always, has prolonged the working life of sliding bearing thus.
