ZJP series Roots vacuum pump is a positive displacement pump, also known as a mechanical booster, is currently available, and one of the major high-vacuum suction device, which works with Roots blower is similar to the use of 8-shaped rotor In the pump housing to synchronize and reverse direction where the best Roots vacuum pump, 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 costs low Roots vacuum pumps, high life. Roots pump of the two rotors in the pump body how to arrange, determines the overall structure of the pump. The overall structural arrangement of domestic and foreign Roots vacuum pumps generally have three options: 1 Vertical: Two rotor axis horizontal installation, but the two rotor plane perpendicular to the horizontal axis constituted Roots vacuum pump uses this structure, the pump intake and exhaust ports positioned horizontally, assembly and connecting pipes are more convenient. But its drawback is that the center of gravity of the pump is too high, poor stability at high speeds, so in addition to the small size of the Roots vacuum pump outside the factory, using not much of this type of structure. 2. Horizontal: horizontal axis of the two rotors installed, the horizontal plane formed of two rotor axis, such a construction the pump inlet at the top of the pump, the pump below the exhaust port (also with this opposite). Below the exhaust port is generally horizontal pick out, so the intake and exhaust direction is perpendicular to each other. An exhaust port connected to an opening tee in two directions, one end of the exhaust pipe, the other end of the die or use the bypass valve connection. This structure is the low center of gravity, good stability at high speed. Domestic and medium-sized pump more of this structure type. 3. The vertical axis: Some foreign two horizontal rotor axis and Roots pump mounted vertically. Assembly clearance is easy to control this structure, the rotor assembly convenient, small footprint, but other gear transmission mechanism assembly and disassembly inconvenience, lubrication system is also more complex.
