New design oil seal for high speed motor of soy milk maker and juice extrator.
That is a new oil seal which is bonded PTFE lip on the seal .
Soy milk maker and Juice extrator are 2 papular household applicance all over the world ,due to it can make fresh . Healthy ,axenic drinks .
But For the machine, motor and seal are very important . When the motor works , shaft speed will reach 20000 r/m to 30000 r/m , it is very high speed . That means seal is very very important between motor shaft and container .
First Generalation of seal is used a silicone gasket . Gasket is Static seal, it can’t used for rotating shaft . Also Silicone is not a good material to seal waters, when working under steam , silicone will be easy to expand , lead to leaking of machine ..
Second Gerneration , almost manufactuer use skeleton oil seal, and also choose a good rubber ( fluoroelastomer ) , some company used Viton of Dupont’s brand instead of FPM rubber .
Rotary Shaft Seal is right and good design for this motor shaft , FPM material also is suitable rubber for high speed motor. So far , Fluororubber oil seal is a standard parts for soy milk machine and Juice Extrator.
But , This seal is still not the perfect . There are some deficiency
1) Fluororubber have a good property of wear resistant and high temperture resistance . However . Viton is still have a big wear loss , due to Shaft speed reach 30000 r/m or more , and viton rubber is not good of self lubricating .
2) In order to improve wear resistance. Some seals manufacturer will add more and more lubrication material into viton . That make the viton much better of wear resistance .but it lead to another problem . Viton rubber become not easy to bond with iron skeleton, bonding strength will be reduced . That there is a potential problem . When shaft working , Rubber is break from the skeleton ,then lead to leaking .
About this problem , it is not easy to find out the problem when Machine factory’s QC inspect the goods from Seal supplier .
3) In order to improve the lubrication of seal , many factory will inject some lubracating oil .
Some Famous manufacturer will use food grade lubracating oil , but some factory use industrial oil . That is not safe for health .
ERM sealing industrial limited company research and design a new oil seal for Soy milk maker and Jucie extrator. We bond a modified PTFE lip on viton oil seal . (see the picture)
1) modified PTFE is much better of ware resistance and lower friction factor than Viton.
That make the seal reduce the abrasion loss, and Extended Machine Life , Low friction factor will be improve self lubrication, it don’t need to inject lubrication oil . Of course there are no oil pollution .
