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 vacuum manufacturer, so the drive power is small. Easy to maintain and repair, low cost, high life. Can be pumping condensable gases. ? Do not alone Hebei Roots vacuum where there must be configured 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. Roots vacuum pump (referred to as the Roots pump) is a rotary positive displacement pumps. It is evolved from the Roots blower. Depending on the scope of work Roots vacuum pump, is divided into vertical atmospheric low Roots vacuum pump; Roots vacuum pump (also called mechanical booster) and high vacuum multi-stage Roots pump. In general, the Roots pump has the following characteristics: in a wide pressure range greater pumping speed; starting fast, able to work immediately; not sensitive to dust and water vapor contained in the gas to be drawn; the rotor does not have to lubricate, oil-free pump chamber; vibration Hebei Roots vacuum where the best, better conditions Roots pump rotor balancing, no vent; small drive power, small mechanical friction losses; compact, small footprint; operation and maintenance low cost. Therefore, Roots pump in metallurgy, petrochemical, paper, food, electronics industry has been widely used.
