Zbk16 Series Roots Vacuum Pump/Vacuum Pump

ZBK series roots vacuum pump is a kind of coarse vacuum acquisition of equipment, it is widely used in papermaking, paper holder, paper pulp molding, chemical industry, medicine, building materials, food, clothing, sugar and other industries, is paper industry slotted network of suction box or long nets paper machine net of suction box vacuum dewatering ideal equipment. In this range ZBK series roots vacuum pump and water ring vacuum pump, which was compared pumping speed, high efficiency, compact structure, small volume, convenient maintenance, long service life, low power consumption. Suction medium for dry, wet air or water mixture, but to be contained in the medium granular material, high dust gas or corrosive substances. Machine this department by motor through the triangle pulley drive active rotor rotation, and through the synchronous gear drive driven gear drive driven rotor rotation, the two rotor mutual contact, and keep the 0.4 mm or so clearance quantity. Rotor and pump body and plate respectively between keep 0.25 mm or so clearance quantity. In the process of operation, in the pump cavity lower, because the two rotor continuous separation, cause volume expansion, on the top because of two rotor continuous tap into cause volume contraction, thus completing suction, exhaust gas, and the effect of the suction side vacuumize, and exhaust side and atmospheric conduction, close to the atmosphere. Pump body export has a sound attenuation box, and at the same time a stable pressure, sealing action to improve the pump efficiency.
