JZJ series vacuum group

Application area Vacuum group used in the fields of Food stuff,medicine,chemical industry,electrical engineering,smelt,weld,dring Features Good suction speed under low vacuum pressure Low noise,low vibration Air cooling,facility ,easy operation Able to normally work under high temperature Built-in filters,high filtering efficiency JZJ series vacuum pump group consists of backing up rotary vane vacuum pump and roots vacuum pump,there is magnet valve between the two pumps interlocked open and close with backing up pump,and micro resistance vacuum gauge to observe residual gas in evacuated unit or port to control the start up of roots pump. The working pressure of this equipment is 133-5Pa,because of the machine is swift to start up and high speed suction rate,it can be used to make vacuum for vacuum selt,welding,drying,pharmacy,electronic,vacuum parts ect. but it is not suitable for evacuation of materials such as high oxygen cotent,poisonous,explosive,high water content,metal corrosive,active to pump oil,dusty gas,also not applicable to transport gas from one port to another port as vacuum transporation unit. This machinewith features like operation stable,simple and easy maintenancecouldbe widely used in foodstuff,chemical industry,pharmacy,filtration ect. industries for vacuum distillation,vacuum concentration,vacuum drying.The vacuum group is sending signals by vacuum sensor to control all the pumps on and off.
