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. End face contour-cooled Roots pumping through both a plum-type rotors, alternating suction and discharge gas to form a vacuum, the rotor includes many curves Henan Roots vacuum applications, such as cycloid white lines and arcs and arc include line between the rotor and the rotor, there is a gap between the rotor and the pump, do not touch, smooth rotation Henan Roots pump prices were steady and smooth pumping gas to exhaust the estuary, the use of three petals type rotor Henan where Roots vacuum pumps, air can guarantee the return port never communicated with the inlet, so that when the pump is working at high differential pressure, exhaust gas can be cooled by the cooler return after the pump cooling pump rotor, without the ability to affect the vacuum motor driven pump moving through V-belt or coupling. The main features of Roots vacuum over a wide pressure range (1-1 × 10-4) has a higher pumping speed and pump chamber without oil, to avoid contamination of the oil vapor vacuum system. · Roots pump vibration and low noise. Small mechanical friction losses, so the drive power is small. Easy to maintain and repair, low cost, high life. Can be pumping condensable gases. ? Do not alone, you must configure before the pump. Only allowed to start at atmospheric pressure started to be before the pump will be able to get the Roots pump inlet pressure to allow the inlet pressure. Forepump for water ring pumps, reciprocating pumps, jet pumps, rotary vane pumps, claw pumps.
