Abstract
The utility model provides relates to a forced circulation mechanical sealing structure with a shaft sleeve, which comprises a main shaft, a pump cover, a gland, a sealing machine and a static ring gland, wherein the gland is fixedly connected on the end surface of the pump cover, the static ring gland is fixedly connected on the end surface of the gland, the shaft sleeve is arranged outside the main shaft, and the main shaft and the shaft sleeve are mounted in the through holes in the pump cover, the gland and the static ring gland; the sealing machine is arranged in the cavity between the inner wall of the pump cover and the gland and the outer wall of the shaft sleeve, cooling water jackets are arranged in a cavity of the sealing machine and outside the shaft sleeve, and the cooling water jackets are communicated with a water entering channel and a water exit channel respectively, which forms the cooling water circulation. The utility model has the beneficial effects that the forced circulation mechanical sealing structure can well protect the main shaft, can avoid the corrosion to the main shaft caused by the leakage of transmission medium, and even can take corrosive liquid as cooling liquid, plays the effect of forced refrigeration under the action of forced circulation, avoids the damage of sealing components in high temperature and improves the safety performance.
Description
Technical field
The utility model relates to the mechanical seal field, especially a kind of tape spool cover pump circulation mechanical seal structure.
Background technique
Existing machinery seals that often sealing effect is undesirable.The cooling effect of machine envelope inside is bad, causes part to cross cause thermal damage, influences sealing.Main shaft lacks enough protective gears outward, in case transmission medium is revealed corrosion main shaft easily.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of good seal performance is provided, and main shaft is had the tape spool cover pump circulation mechanical seal structure of good protection effect.
The utility model solves the technological scheme that its technical problem adopts: this tape spool cover pump circulation mechanical seal structure, comprise main shaft, pump cover, gland, machine envelope and seal end plate, wherein gland is fixedly connected on the end face of pump cover, seal end plate is fixedly connected on the end face of gland, described main shaft is provided with axle sleeve outward, and main shaft and axle sleeve are installed in the through hole in pump cover, gland and the seal end plate; Be provided with the machine envelope in the cavity between pump cover, gland inwall and the axle sleeve outer wall, be provided with cooling jacket outward with axle sleeve in the machine sealing chamber, cooling jacket is connected with intake tunnel, exhalant canal respectively and forms the cooling water circulation.
Described intake tunnel is arranged in the seal end plate, and intake tunnel is connected with cooling jacket; Described exhalant canal is arranged in the gland, and exhalant canal is connected with cooling jacket.
The effect that the utility model is useful is: the utility model has carried out excellent protection to main shaft, can prevent because the corrosion that the leakage of transmission medium causes main shaft, even can be with corrosive liquid as cooling liquid; Played under the pump circulation effect of cooling liquid and forced cold effect, avoided the destruction of high temperature for sealed member, Safety performance improves; Rational in infrastructure, make things convenient for industrial production, can be used for the chemical medium transmission, be applicable to petroleum chemical industry, industries such as varieties of food items, medicine.
Description of drawings
Fig. 1 is a sectional view of the present utility model;
Description of reference numerals: main shaft 1, pump cover 2, gland 3, machine envelope 4, axle sleeve 5, cooling jacket 6, intake tunnel 7, exhalant canal 8, seal end plate 9.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this tape spool cover pump circulation mechanical seal structure, comprise main shaft 1, pump cover 2, gland 3, machine envelope 4 and seal end plate 9, wherein gland 3 is fixedly connected on the end face of pump cover 2, seal end plate 9 is fixedly connected on the end face of gland 3, the described main shaft 1 outer axle sleeve 5 that is provided with, main shaft 1 and axle sleeve 5 are installed in the through hole in pump cover 2, gland 3 and the seal end plate 9; Be provided with machine envelope 4 in the cavity between pump cover 2, gland 3 inwalls and axle sleeve 5 outer walls, machine seals in 4 chambeies and the axle sleeve 5 outer cooling jackets 6 that are provided with, cooling jacket 6 is connected with intake tunnel 7, exhalant canal 8 respectively and forms the cooling water circulation, and described cooling liquid can be is with corrosive liquid.Described intake tunnel 7 is arranged in the seal end plate 9, and intake tunnel 7 is connected with cooling jacket 6; Described exhalant canal 8 is arranged in the gland 3, and exhalant canal 8 is connected with cooling jacket 6.
Installation process: this machine envelope is the whole machine envelope of unit loading type, when mounted, earlier machine envelope 4, pump cover 2, gland 3, axle sleeve 5, seal end plate 9 connections is become one-piece element, this unit loading type machine envelope is through on the main shaft 1 to get final product when general assembly.
When operation, outside cooling liquid is connected to the intake tunnel 7 on the seal end plate 9, under the effect of pressure, cooling liquid flows to machine envelope 4 along the passage in the seal end plate 9, cooling liquid is cooled off machine envelope 4 under the guiding of cooling jacket 6, and the passage in gland 3 flows out from exhalant canal 8, and finish a circulation, play pressure cooling action to whole mechanical seal.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
