High Efficiency cast iron Roots ZBK Vacuum Pump Vacuum supplied For tissue Paper Making Machine

ZBK series Roots vacuum pump is a kind of equipment for obtaining rough vacuum.

It is widely used in papermaking, chemical, pharmaceutical, building materials, food, clothing, sugar and other industries. It is a suction box for the fourdrinier net or fourdrinier paper machine in the paper industry. Ideal equipment for vacuum dehydration. In this range, compared with water ring vacuum pumps, ZBK series roots vacuum pumps have the advantages of large pumping speed, high efficiency, compact structure, small size, convenient maintenance, long life, and low power consumption. The suction medium is dry, humid air or water mixture, but the medium must not contain particulate matter, high dust gas or corrosive substances.

2. Structure and working principle This machine is driven by the motor through the V-belt pulley to drive the active rotor, and the synchronous gear drives the driven gear to drive the driven rotor to rotate. The two rotors do not touch each other and maintain a gap of about 0.4mm. There is a gap of about 0.25mm between the rotor and the pump body and the end cover. During operation, in the lower part of the pump cavity, due to the continuous separation of the two rotors, the volume is expanded. At the upper part, the continuous connection of the two rotors causes the volume to shrink, thus completing the function of suction and exhaust, and creating a vacuum on the suction side. , And the exhaust side is connected to the atmosphere, close to atmospheric pressure

The suction medium can be dry, humid air or gas-water mixed gas, but the medium cannot contain larger particles of solid matter
