Two Roots vacuum pump rotor layout how to determine the overall structure of the pump. The overall structural arrangement of domestic and foreign Roots vacuum pump are generally three options: 1 vertical: horizontal axis of the two rotors installed, but a plane perpendicular to the horizontal axis of the two rotors formed, this arrangement, the pump intake and exhaust ports Roots vacuum uses horizontal setting, 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 pump, but not too much use of this structure type. 2. Horizontal: two horizontal axis of the rotor Roots vacuum pumps offer installation, two horizontal plane rotor axis configuration, such a configuration of the pump inlet above the Roots vacuum pump, an exhaust port in below the pump (also to the contrary). Lower exhaust port usually pick out the horizontal direction, so the intake and exhaust direction is perpendicular to each other. An exhaust port connected to the opening tee in two directions, one end of the exhaust pipe Roots pump prices, the other end of the dead, or use the bypass valve connection. Feature of this structure is the low center of gravity, good stability at high speeds. Domestic and medium-sized pump more of this structure type. 3. Vertical shaft: Some foreign rotor axis and two horizontal Roots pump installed vertically. This structure is easy to assemble gap control, rotor assembly convenient, small footprint, but other gear transmission assembly and disassembly inconvenience lubricating device is also more complicated. Gas-cooled Roots pumping main structure: Plum Rotor: To rotor is made of ductile iron casting by high performance by high-precision CNC machining, high precision, right profile design and high-precision machining is to ensure that the overall performance of key. Precision rotor balancing test. Synchronous Gear: Gear is one of the most important part of the synchronization Roots vacuum pump, which is used to ensure synchronous rotation of the two rotors to maintain a certain gap between the rotor. Gear surface by high-frequency quenching, and grinding is made from a special high-precision, low noise.
