Roots vacuum structural features (1) uncompressed Roots vacuum pump chamber, no exhaust valve. Simple and compact structure Hebei Roots vacuum manufacturers, wholesale, to be pumping gas in the dust and water vapor is not sensitive; (2) a relatively low compression Hebei Roots vacuum outlets, poor ventilation of hydrogen; (3) the shape of the rotor surface more difficult the more complex curves cylinder, machining and inspection. Roots vacuum at home and abroad in recent years has been rapid development. In refining, petrochemical, electrical, electronics and other industries has been widely used. 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. · Vibration, little noise. · Mechanical friction losses small Hebei Roots pump price, 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.
