Labyrinth seal device successfully applied Dryer

In order to better seal the dryer , mechanical R & D personnel to undergo many , many studies , and ultimately a " labyrinth " security seals seal and successfully applied slime dryer, rotary dryer and three drum drying dry fields.
Research found : Dryer labyrinth seal is curved so that the air flow through the channels, generation of fluid resistance, so that air leakage is reduced .
Dryer according to the different labyrinth passage direction , the labyrinth seal into the axial and radial labyrinth seal. Slime dryer labyrinth seal structure is simple , there is no contact surface , so there is no wear problems , it is not traverse of the cylinder .
Considering the inherent cylinder and labyrinth seal manufacturing error , and the cylinder axis of the bending stiffness , the gap between adjacent labyrinth ring is not too small , generally not less than 20-40mm.
The greater the gap , the fewer the number labyrinth sealing effect is worse . Therefore, the labyrinth seal is only applicable where the gas pressure is small , or in combination with other sealing structure . This technological innovation allows Huachang Machinery tasted the sweetness , tamper seal labels but this little seal limitations Huachang Machinery recently came to do a number of initiatives in the hope that other sealing technology breakthrough.
