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 Roots vacuum pumping speed, to be pumping gas containing dust and water vapor is not 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 the ability to communicate in Henan Roots vacuum vent manufacturers, so that when the pump is working at high differential pressure, exhaust gas can be cooled by the cooler return after cooling pump Roots vacuum pump rotor Henan direct, without affecting the vacuum The motor-driven pump by moving V-belt or coupling. BZJ series two-stage vacuum pump Roots (Roots pump), the company is based on 2ZJ series single-stage Roots pump on, carefully study successfully developed a new generation of replacement products, the indicators have reached similar foreign products. In China, the main form of high vacuum Roots vacuum unit to obtain multiple Roots pump is coupled in series Henan Roots vacuum pump before use, although more than one series Roots pump more flexible, with Roots vacuum pump is widely used and improve the technical requirements related industries, there is a growing need for an easy to use and maintain, and reliable operation of the new Roots vacuum pump to improve their productivity and reduce production costs.
