model zj/zjp roots vacuum pump-电子pg麻将胡了

three optional form of sealing:
mechanical sealing

application:
widely applied to the process such as vacuum degassing, vacuum metallurgy, vacuum drying and vacuum heat treatment.large-scale pump is more suitable for the applications such as steel vacuum processing, spatial modeling and low-density wind tunnel device etc.
it can also be applied to the manufacturing process of evaporation, distillation and drying in the industries such as chemical, food, medicine, electric power equipment.

main characteristi:
high rotating speed and vonvenient operation and maintenance.
simple structure ,convenient operation and maintenance.
fixed motor ,no axial displacement.
with high-precision transmission gear,skf high-precision bearing and good dynamic balance,it ensures products featured by low noise and smooth running.
with balanced stainless steel mechani sealing and oil-free structure for pump cavity,it is applied to extract general air and all kinds of special gases.
compared with other mechanical vacuum pump,it has significant energy conservation effect.
matched with all kinds of fore-pump,it can be extensively used in all kinds of processing range.
