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, such as cycloid white lines and arcs and arc, including lines, the rotor and the rotor Room exists between the rotor and pump a certain gap, do not touch, smooth rotation, is stable and smooth pumping exhaust gases to the estuary, the use of three petals type rotors, can never guarantee the return port and air intake inlet connected, so that when the pump is working at high differential pressure, exhaust gas can be cooled by the cooler return after the pump rotor Roots vacuum pump cooling outlets, and will not affect the ability of Roots vacuum pumps, motors move by V-belt or coupling drive pump. ZJP series Roots vacuum pump is the perfect type of a structure volume Roots vacuum pump where the cheapest, it's biggest advantage is higher where the best Roots vacuum pumping speed at low inlet pressure, and can be to achieve a relatively high ultimate vacuum. Since the pump is directly used as the main parts of the exhaust between the shaft housing, rotor and cap no relative movement contact, so stable ZJP series Roots vacuum pumps operating performance, long life, low maintenance costs. The current vacuum pump is widely used for smelting, vacuum welding, vacuum casting, vacuum coating, vacuum dynamic tests and chemical and pharmaceutical, electric vacuum casting manufacturing various vacuum processing can be achieved within the vacuum pump range.
