Embodiment Construction

[0010] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0011] figure 1 The sealing device shown is installed between the motor and the structural parts. The sealing device establishes a transition zone between the motor 7 and the structural part 1 to realize the isolation of both sides. The sealing device is connected with the motor 7 and the structural part 1 by welding.

[0012] The device includes a housing 2, and the housing 2 is divided into a plurality of high-pressure chambers and negative-pressure chambers through a partition plate 5. In this embodiment, one high-pressure chamber 4 and one negative-pressure chamber 6 are taken as examples. To illustrate. The output shaft 8 continuously runs through the structural component 1 , the casing 2 , the partition plate 5 , the high pressure chamber 4 and the negative pressure chamber 6 , and dynamic sealing can be realized through the high pressure...

Abstract

The invention discloses a sealing device used between a motor and structural parts, the device comprises a casing (2), the casing (2) divides its interior into a high-pressure chamber (4) and a high-pressure chamber (4) through a partition plate (5). The negative pressure chamber (6), the high pressure chamber (4) are connected to the inlet connection pipe (3), and the negative pressure chamber (6) is connected to the suction connection pipe (9). The device has good sealing performance and simple structure, which prevents the environmental liquid from leaking into the motor and the impurities in the motor from leaking into the environmental liquid.

Description

technical field [0001] The invention relates to the field of sealing of a motor, in particular to a sealing device used between a motor and structural components. Background technique [0002] At present, the shaft end seal of the motor commonly used in the prior art is sealed through the gap between the rotating shaft and the casing with a rubber seal ring, etc. This structure can well meet the sealing requirements of environmental liquids under general environmental conditions. Requirements, but for the environment with special requirements, the sealing structure such as the sealing ring can no longer meet the sealing requirements, and it needs to be further sealed. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art and provides a sealing device with good sealing performance and simple structure used between the motor and structural components. [0004] In order to solve the above technical problems, the present invention is ach...
