Abstract
A centrifugal pump sealing device comprises a shaft, a helix sealing part, a sealing water pipe, a bearing base, an impeller, a sealing box, an asbest rope, a pressing cover and a shaft sleeve. The shaft sleeve is mounted on the shaft, the helix sealing part is mounted at an inner end part of the shaft sleeve, the bearing base is mounted on the helix sealing part, the asbest rope is mounted on the shaft sleeve, the sealing box is mounted on the asbest rope, and the sealing water pipe is mounted on the sealing box. The utility model has advantages of good sealing effect, ensured pump normal operating, few changing time, small material consumption, low operating cost, small maintenance engineering amount, time and labor saving, small operating labor strength, high sealing efficiency and long service life, and can be widely applied to the sealing process of the centrifugal pump.
Description
One, technical field
The utility model relates to the centrifugal pump sealing mechanism, particularly a kind of centrifugal pump seal arrangement.
Two, background technique
Traditional centrifugal pump axle sleeve sealing, the general packing that adopts materials such as graphite, butter, polyethylene to make, need the 6-8 root, tightly on axle sleeve, be equipped with parts such as seal cage, interstage sleeve again in the hope of sealing, though above-mentioned sealing means has been brought into play important function for centrifugal pump sealing, it exists following shortcoming or deficiency simultaneously: 1. seal cage, filler, interstage sleeve and axle sleeve be because the high speed rotating of pump and fragile, causes and change frequent, high material consumption, operating cost height; 2. the maintenance engineering amount is big, and is time-consuming, operation labor intensity height; 3. sealing effect is poor, influences the normal operation of pump.
Three, model utility content
Order of the present utility model provides a kind of centrifugal pump seal arrangement, adopts the co-ordinative construction of spirality Sealing, packing seal element and water seal sealing etc., the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
Centrifugal pump seal arrangement described in the utility model comprises axle, spiral seals, sealing water pipe, bearing support, impeller, sealed case, asbestos rope, gland and axle sleeve.Described axle sleeve is installed on the axle, and the inner end of axle sleeve is equipped with spiral seals, and bearing support is installed on the spiral seals, and asbestos rope is installed on the axle sleeve, and sealed case is installed on outside the asbestos rope, and the sealing water pipe is installed on the sealed case.
Wherein, described bearing support is provided with inner convex platform.Described sealed case is provided with outer lug boss and matches with inner convex platform on the bearing support.Described spiral seals is an outer surface shape structure in the shape of a spiral.Described asbestos rope is installed on the axle sleeve in the sealed case outer end, is compressed by gland.
The utility model has following advantage compared with prior art:
1, good sealing effect guarantees the normal operation of pump
2, the replacing number of times is few, materials consumption is little, operating cost is low;
3, the maintenance engineering amount is little, saving of work and time, and operation labor intensity is little;
4, leakage efficiency height, long service life.
Four, description of drawings
Accompanying drawing is a kind of example structure schematic representation of the present utility model
Five, embodiment
Consult accompanying drawing, a kind of centrifugal pump seal arrangement, comprise axle 1, spiral seals 2, sealing water pipe 3, bearing support 4, impeller 5, sealed case 6, asbestos rope 7, gland 8 and axle sleeve 9, it is characterized in that described axle sleeve 9 is installed on the axle 1, the inner end of axle sleeve 9 is equipped with spiral seals 2, and bearing support 4 is installed on the spiral seals 2, and asbestos rope 7 is installed on the axle sleeve 9, sealed case 6 is installed on outside the asbestos rope 7, and sealing water pipe 3 is installed on the sealed case 6.
Wherein, described bearing support 4 is provided with inner convex platform.Described sealed case 6 is provided with outer lug boss and matches with inner convex platform on the bearing support 4.Described spiral seals 2 is an outer surface shape structure in the shape of a spiral.Described asbestos rope 7 is installed on the axle sleeve 9 in sealed case 6 outer ends, is compressed by gland 8.Impeller 5 is installed on an end of axle 1 and contacts with bearing support 4.
