Abstract
The utility model discloses a water pump sealing device which can solves the problems existing in the prior art of poor sealing performance, heavy wear of shaft sleeves and high cost. A water pump sealing device, which is arranged at the junction of casings at two ends of the water pump and a shaft, comprises a shaft sleeve on the shaft and asbestos packing; and soft sealing packing is added between the water pump casings and the shaft sleeve. The soft sealing packing of the water pump sealing device does not wear the shaft sleeve, has good sealing performance and convenient addition, and can solves the water leakage problem of the sealing water pump with the asbestos packing.
Description
Technical field
The utility model belongs to production field of metallurgy, specifically, relates to a kind of water pump gland.
Background technique
Metallurgical production accessory water pump cooperates to form with asbestos packing and axle sleeve seals the high pressure water outflow, but after operation a period of time water leakage phenomenon is arranged promptly, and compressing the packing current can be little, but can not stop; But only dependence compresses the packing effect and just can not solve water leakage phenomenon after axle sleeve weares and teares, use import packing and axle sleeve instead and cooperate the formation sealing, working life neither be very long, thoroughly handle seepy question and have only the replacing axle sleeve, but cost is big, the labor intensity height.
How to guarantee airtight quality on the basis that need not change axle sleeve, then be the design problem that the utility model faced.
Summary of the invention
The utility model provides a kind of water pump gland, can solve poor sealing performance, axle sleeve serious wear and the high problem of cost that prior art exists.
For solving the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of water pump gland is located at the junction of water pump two ends housing and axle, comprises the axle sleeve on the axle and the asbestos packing of envelope axle sleeve, it is characterized in that: add soft sealed packing between described water pump cover and the axle sleeve.
In technique scheme of the present utility model, also have following technical characteristics: the water pump cover at corresponding described soft sealed packing place is provided with aperture.
In technique scheme of the present utility model, also has following technical characteristics: arch silk and block in the described aperture with plug.
In technique scheme of the present utility model, also have following technical characteristics: the diameter of described aperture is 10～12mm.
In technique scheme of the present utility model, also have following technical characteristics: described asbestos packing is two, and described soft sealed packing is between described two asbestos packings.
Compared with prior art, advantage of the present utility model and good effect are:
1, need not to change axle sleeve, can save cost;
2, directly on the basis of existing structure, by aperture injection soft sealed packing, operation easily;
3, the soft sealed packing axle sleeve that do not wear and tear, good sealing effect, it is convenient to add, and can solve asbestos packing water-sealed pump seepy question.
