The pump and the unit can reach a variety of extreme vacuum and working pressure. In the following cases, can use air pump itself or its system.
① the load is particularly large;
② pumping time is short;
③ coarse vacuum to high vacuum are required large pumping speed;
④ need to avoid the ordinary pump working medium occasions.
The pump and system can be widely used in vacuum smelting, vacuum drying, vacuum impregnation, vacuum distillation, vacuum degassing, aeronautical simulation test, gas transportation, vacuum suction and power station vacuuming and other vacuum operations.
