Abstract
The utility model discloses a kind of roots blower combined sealing structure, it is characterized in that it includes side cover（1）, main shaft（2）And seal receptacle（3）, the seal receptacle（3）Installed in main shaft（2）On, seal receptacle（3）Installed in side cover（1）In, seal receptacle（3）Buckle-type sealing ring is installed in the inner part（4）, the buckle-type sealing ring（4）With side cover（1）Contact site be face contact, the seal receptacle（3）On be additionally provided with fuel tank side（5）Polytetrafluoro seal（6）, polytetrafluoro seal（6）With side cover（1）Contact site also for face contact.Close ring type filling of the utility model due to using full buckle-type, is the sealing of end face face, can effectively reduce the leakage quantity that leaks, polytetrafluoro seal is resistant to 250 DEG C of high temperature, and its linear velocity can be reached after 50M/S, two seal combinations, make blower fan there is fan body side not leak, the advantage of service life length.
Description
Technical field
The utility model is related to a kind of sealing structure of roots blower.
Background technology
Sealing gland is widely used in air seal on the inside of the side cover of roots blower, and common blower fan sealing gland is sealed using Mi Gong, when
Using when at a high speed with high pressure roots blower, because its fan body side is large-minded, pressure is high, and temperature is high, causes blower fan
External leakage is increased, and influences fan delivery, and higher by external leakage gas temperature, rotation speed of fan is high, further results at blower fan fuel tank
The conventional oil sealing life-span substantially reduces.
Utility model content
There is provided a kind of service life length, gas aiming at the deficiency that above-mentioned prior art is present for the purpose of this utility model
The few roots blower sealing structure of external leakage rate.
The technical solution adopted in the utility model is as follows：
A kind of roots blower combined sealing structure, it is characterized in that it includes side cover, main shaft and seal receptacle, the seal receptacle
On main shaft, seal receptacle is arranged in side cover, and seal receptacle is provided with buckle-type sealing ring in the inner part, and the buckle-type is close
Seal ring is contacted with the contact site of side cover for face, and the polytetrafluoro seal in fuel tank side, poly- four are additionally provided with the seal receptacle
Fluorine seal is also contacted with the contact site of side cover for face.
The buckle-type sealing ring is arranged in the groove on seal receptacle.
Have buckle-type sealing ring thickness 1/3-2/3's in vain to the bottom portion of groove in the inner ring face of the buckle-type sealing ring
Distance.
The beneficial effects of the utility model have：
Due to using the close ring type filling of full buckle-type, it is the sealing of end face face, can effectively reduces the leakage quantity that leaks, polytetrafluoro
Seal is resistant to 250 DEG C of high temperature, and its linear velocity can be reached after 50M/S, two seal combinations, and make blower fan has fan body side
Do not leak, the advantage of service life length.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings：
As shown in figure 1, the utility model it include side cover 1, main shaft 2 and seal receptacle 3, the seal receptacle 3 is arranged on master
On axle 2, seal receptacle 3 is arranged in side cover 1, and seal receptacle 3 is provided with buckle-type sealing ring 4 in the inner part, the buckle-type sealing
Ring 4 is contacted with the contact site of side cover 1 for face, and the polytetrafluoro seal 6 in fuel tank side 5 is additionally provided with the seal receptacle 3, is gathered
Polytetrafluoroethylsealed sealed part 6 is also contacted with the contact site of side cover 1 for face.Lubricating oil is housed in fuel tank side 5.
The utility model takes preferred buckle-type sealing ring 4 in the groove on seal receptacle 3, and buckle-type sealing ring 4
Inner ring face have the thickness 1/3-2/3 of buckle-type sealing ring 4 distance in vain to the bottom portion of groove, so have a small amount of gas from
Compressing buckle-type sealing ring 4, makes the contact with side cover 1 of buckle-type sealing ring 4 closer, it is ensured that will not after the leakage of fan body side
Gas leakage.
The utility model loads buckle-type sealing ring 4 after seal receptacle 3, and seal receptacle 3 is loaded into main shaft 2, then by poly- four
Fluorine seal 6 loads side cover 1, then is attached to side cover 1 on seal receptacle 3 together with polytetrafluoro seal 6 using device.
Other undeclared parts that the utility model is related to are same as the prior art.
