ZJ, ZJP old Roots vacuum pumps are widely used in the manufacture of other occasions metals, non-metallic materials industry, vacuum degassing, vacuum melting, vacuum surface treatment and low-density wind tunnel testing and electrical equipment, vacuum freeze-drying equipment, the pump water ring vacuum pumps, liquid ring vacuum pumps after a series configuration, more suitable for the chemical industry vacuum polymerization reaction, decomposition and food industry vacuum distillation, vacuum drying, vacuum crystallization process. ZJ series Roots vacuum pump is a rotary positive displacement pumps, must have before the pump with before use, in a wide range of pressures greater pumping speed was pumping gas for dust and water vapor does not contain sensitive, widely used in metallurgy, chemical industry, food, electronics and other industries coating. Gas-cooled Roots pumping through both a plum-type rotors, alternating suction and discharge gas to form a vacuum, face contour shape of the rotor includes a lot of curves Roots vacuum wholesale prices, as cycloid white lines and arcs, and arc, including line between the rotor and the rotor between the rotor and the Roots vacuum pump uses a certain gap, do not touch, smooth rotation is smooth and smooth pumping gas to exhaust estuary Roots pump prices, thanks trilobes type rotor, can never be guaranteed cool air return port communicating with the intake port, so that when the pump is operated at high differential pressure, the exhaust gas can be cooled by aftercooler cooling pump returns the pump rotor, without affecting the vacuum The ability to move the motor through V-belt or coupling drive pump.
