Description
Technical Field
A machine sealing oil belongs to the technical field of powder processing machinery.
Background
The impeller feeders used in the places of feeding of powder material pneumatic transmission, blanking of large material bins and the like do not have good pressure-resistant and wear-resistant sealing mechanisms and use pressure-resistant sealing oil, and some impeller feeders produced by units can use new equipment for several days, ash leaks after several days, the sealing mechanisms are not wear-resistant, and certainly, the impeller feeders cannot withstand pressure; the pneumatic conveying is an ideal conveying method for powdery materials, but the impeller feeder can only be used under normal pressure or low pressure because a proper pressure-resistant and wear-free impeller feeder and a pressure-resistant sealing oil for sealing cannot be found so far, and a design unit rarely adopts the conveying method.
