Energy-saving Technical Reform of the Fourth Generation Vacuum Jet Device

The third generation vacuum jet device has not high efficiency on preloading vacuum.After the improvement for the fourth-generation energy-saving type vacuum preloading jet device,it separates jet pump from jet device in structure,thus makes moisture completely separated,the device adopts small power pump replace the original jet pump,greatly improves the efficiency of suction,and can be widely used in the construction of vacuum preloading.
