ZJP series Roots Roots vacuum pump is a positive displacement pump, also known as a mechanical booster, is currently available, and one of the major high-vacuum pumping equipment Roots vacuum where the cheapest, it works with Roots Similar blower, is the use of 8-shaped rotor in the pump housing to synchronize and turn the opposite direction, thereby completing the intake and exhaust. The main features of Roots vacuum pump over a wide pressure range (1-1 × 10-4) has a higher pumping speed and pump chamber without oil, to avoid the oil vapor pollution vacuum systems. Vibration small, noise. Small mechanical friction loss, so the drive power is small. Easy to maintain and repair, low cost, high life expectancy. Roots vacuum pump (referred to as the Roots pump) is a rotary positive displacement pump. It is evolved by the Roots blower. According to Roots vacuum pump Roots vacuum range of different purposes, divided into vertical atmospheric low vacuum Roots pump; Roots vacuum pump (also called mechanical booster pump) and high vacuum multi-stage Roots pump. In general, the Roots pump has the following characteristics: over a wide pressure range has a higher pumping speed; starting fast, able to work immediately; not sensitive to dust and water vapor contained in the gas to be pumped; and rotor need not be lubricated, oil-free pump chamber; vibration, rotor balancing conditions were better Roots vacuum manufacturers, no exhaust valve; small drive power, small mechanical friction loss; compact, small footprint; low operation and maintenance costs. Thus, vacuum pumps in the metallurgical, petrochemical, paper, food, electronics industry has been widely used.
