Abstract
The invention discloses a sealing device used between a motor and a structural component, which comprises a shell (2), wherein the shell (2) divides the interior of the shell into a high-pressure chamber (4) and a negative-pressure chamber (6) through a partition plate (5), the high-pressure chamber (4) is connected with an inlet connecting pipe (3), and the negative-pressure chamber (6) is connected with an air suction connecting pipe (9). The device leakproofness is good, simple structure, and is fabulous to prevent that environmental liquid from leaking into the motor and the impurity in the motor spills to the liquid of environment.
Description
Technical field
The present invention relates to a kind of field of sealing technology of motor, particularly a kind of sealing device that is used between motor and the structure member.
Background technology
At present, the shaft end seal of the motor that generally adopts is by form sealings such as the employing of the gap between rotating shaft and shell rubber seal in the prior art, this kind structure can be good at satisfying the requirement of the sealing of environmental liquids under the general environment condition, but when the environment of specific (special) requirements is arranged, the hermetically-sealed construction of forms such as sealing ring no longer can satisfy the requirement of sealing, need be to its further sealing.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of good airproof performance is provided, the sealing device that is used between motor and the structure member simple in structure.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of sealing device that is used between motor and the structure member comprises housing, and key is that described housing is divided into high-pressure chamber and vacuum chamber by demarcation strip with its inside, and high-pressure chamber connects entrance sleeve, and vacuum chamber connects the adapter of bleeding.
Each 1 of described high-pressure chamber, vacuum chamber.
Compared with prior art, the invention has the beneficial effects as follows: this device can be realized movable sealing by the high-pressure chamber of enclosure interior and cooperating of vacuum chamber, has further strengthened sealing effectiveness, prevented the liquid motor that bleeds, prevented that also the impurity in the motor from spilling.
Description of drawings
The cutaway view of Fig. 1 sealing device
The adapter of bleeding of 1 structure member, 2 housings, 3 entrance sleeves, 4 high-pressure chamber, 5 demarcation strips, 6 vacuum chamber, 7 motors, 8 output shafts, 9
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
Sealing device shown in Figure 1 is installed between motor and the structure member, and sealing device is set up transition region between motor 7 and structure member 1, realizes the isolation to both sides, and sealing device adopts welding manner to be connected with motor 7, structure member 1.
This device comprises housing 2, and housing 2 is divided into a plurality of high-pressure chamber and vacuum chamber by demarcation strip 5 with its inside, and present embodiment is that example is illustrated with 4,1 vacuum chamber 6 of 1 high-pressure chamber.Output shaft 8 runs through structure member 1, housing 2, demarcation strip 5, high-pressure chamber 4, vacuum chamber 6 continuously, can realize movable sealing by high-pressure chamber 4 and vacuum chamber 6.High-pressure chamber 4 connects entrance sleeve 3, is used for feeding Compressed Gas to high-pressure chamber 4; Vacuum chamber 6 connects the adapter 9 of bleeding, and is connected with negative pressure system.
Motor 7 must be realized power output by output shaft 8 in when work under the liquid, and in outputting power, output shaft 8 will pass motor housing, may cause outside liquid to bleed oil leakage in motor 7 or the motor 7 in outside liquid.At first Wai Bu compress air system feeds compressed air (air or helium etc.) by entrance sleeve 3 in high-pressure chamber 4, makes the gas pressure in the high-pressure chamber 4 be higher than fluid pressure in the external environment condition, and gas can spill, and liquid cannot bleed.Take over 9 by bleeding and link to each other with negative pressure system such as vacuum system, make the pressure of vacuum chamber 6 be lower than the pressure of high-pressure chamber 4, gas bleeds from high-pressure chamber 4 vacuum chamber 6, prevents that the impurity in the motor 7 from spilling.The continuous operation of external compression gas system is used for replenishing the gas that the course of work is revealed.
Claims (2)
1. sealing device that is used between motor and the structure member, comprise housing (2), it is characterized in that, described housing (2) is divided into high-pressure chamber (4) and vacuum chamber (6) by demarcation strip (5) with its inside, high-pressure chamber (4) connects entrance sleeve (3), and vacuum chamber (6) connects the adapter (9) of bleeding.
2. a kind of sealing device that is used between motor and the structure member according to claim 1 is characterized in that, each 1 of described high-pressure chamber (4), vacuum chamber (6).
