Abstract
The utility model relate to an improved mechanical seal part for a stirrer, which belongs to the technical field of stirrer equipment and is used for improving the mechanical seal of the stirrer and prolonging the bearing life. The technical scheme of the utility model is as follows: the improved mechanical seal part consists of a bearing gland, a mechanically-sealed gland, a bearing, a spring, a static ring, a movable ring, a shaft sleeve and an end cover, wherein the bearing gland, the mechanically-sealed gland and the static ring are arranged on the end cover of the stirrer; the movable ring, the bearing and the spring are arranged on the shaft sleeve; the spring is arranged between the static ring and the mechanically-sealed gland; and the shaft sleeve is an integrated turned component. Due to adoption the mechanical seal part with the big spring, the possibility of spring failure can be reduced, and the phenomenon of blockage by medium is easy to occur; meanwhile, the mechanical seal part is easy to mount, and the service life of the mechanical seal part is prolonged; and the shaft sleeve of the mechanical seal part is integrally turned and formed, the mechanical seal and the bearing vibration are small, and the mechanical seal and the bearing life can be both improved.
Description
Technical field
The utility model relates to a kind of mechanical seal device of storage tank side formula stirrer, belongs to the agitator means technical field.
Background technique
Stirrer is industrial and mining enterprise's equipment commonly used, and stirrer need be installed at the storage tank sidewall by the enterprise that has, and to stir the medium in the storage tank, medium is mixed.Stirrer in use need carry out the supporting machinery sealing; The sealing of stirrer supporting machinery is different with common mechanical seal for pump; Owing on its axle sleeve bearing has been installed; Increased the integral body vibrations of mechanical seal, reduced the working life of mechanical seal, therefore existing supporting machinery sealing is very short working life.In addition, stirrer mechanical seal is longer with respect to conventional machinery sealing entire length, has increased the difficulty of the design and the manufacturing of mechanical seal.
The model utility content
The utility model technical problem to be solved provides a kind of improved stirrer mechanical seal that mechanical seal and bearing life can be improved.
The technological scheme that solves the problems of the technologies described above is:
A kind of improved stirrer mechanical seal; It is made up of bearing gland, machine sealed cover, bearing, spring, stationary ring, rotating ring, axle sleeve, end cap; Bearing gland, machine sealed cover, stationary ring are installed on the end cap of stirrer, and rotating ring, bearing are installed on the axle sleeve, and its improvements are; Described spring is one, and spring is installed between stationary ring and the machine sealed cover.
Above-mentioned improved stirrer mechanical seal, described axle sleeve are whole car system processing component.
The beneficial effect of the utility model:
The utility model adopts the mechanical seal of big spring, can reduce the probability of spring failure, is not easy to take place to be installed easily simultaneously by the medium phenomenon of blocking, has increased the working life of mechanical seal; The whole car of mechanical seal sleeve is processed type, and mechanical seal and bearing vibrations reduce, and mechanical seal and bearing life can be improved.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark is following among the figure: bearing gland 1, machine sealed cover 2, bearing 3, spring 4, stationary ring 5, rotating ring 6, axle sleeve 7, end cap 8.
Embodiment
The utility model is made up of bearing gland 1, machine sealed cover 2, bearing 3, spring 4, stationary ring 5, rotating ring 6, axle sleeve 7, end cap 8.
Show among the figure that bearing gland 1, machine sealed cover 2, stationary ring 5 are installed on the end cap 8 of stirrer, rotating ring 6, bearing 3 are installed on the axle sleeve 7.
Improvements of the utility model are that original spring is a plurality of little springs, are installed in the machine sealed cover 2, change a big spring 4 at present, and spring 4 is installed between stationary ring 5 and the machine sealed cover 2.Spring 4 is installed between stationary ring 5 and the machine sealed cover 2, play adjustment sealing surface compact power effect, make sealing surface keep the applying effect of liquid film.Adopt big spring more less, be not easy to take place, increased mechanical seal working life by the medium phenomenon of blocking than the probability that spring failure appears in little spring.
Another improvement of the utility model is that the mechanical seal sleeve 7 of original welding fabrication is changed into whole car system; Increased axle sleeve 7 itself to neutrality; Reduce manufacturing tolerance, reduced the velocity of vibration of axle sleeve 7, mechanical seal and 3 life-spans of bearing can be improved with axle.
