Introduction:
JZJA (P) LG series screw vacuum pump system belongs to a non-oil dry vacuum system with roots pump (main pump and auxiliary pump), dry screw pump (front pump). The working principle and structure of the rotz pump are similar to the screw pump. The vacuum system can be assembled according to the size of pump system, vacuum receiver and work pressure. The range of available suction in variable pumps ranges from 1:2 to 1:8.

Advantages:
1) have the advantages of roots pump and screw pump.
2) large capacity, high capacity, with large capacity roots pump.
3) energy saving.
4) high suction capacity under high vacuum pressure.
5) automatic control system
6) can be used for corrosive gas pumps.
7) small area requires vertical or stepped construction.
8) self-protection function, applicable to overload, overcurrent, water break.
9) it is difficult to collect dust or particles, especially for condensing medium or vacuuming.

Application:
Can be widely used in medicine, chemical industry, aerospace, electricity, solar energy, metallurgy, food and other industries. In chemical industry, vacuum distillation, vacuum evaporation, vacuum dehydration, crystallization and other processes are required. In power industry, vacuum impregnating and vacuum drying process are used. In addition, it is an ideal choice for vacuum coating, vacuum melting, heat treatment, oil filtration, vacuum freezing, and space simulation test.
