Gas-cooled Roots pumping main structure: Bearings: a fixed axis uses double row angular contact ball bearings, telescoping end uses roller bearings with high load capacity. These bearings can withstand high speed and load Hebei Roots pump prices in order to ensure that the gap between the gear and the rotor between. Seal: Roots pump seal with a two-way internal lip seal, can effectively prevent the flow of fluid two-way mutual, consistent fluid composition. Drive shaft seal using the oil seal. Roots pump is characterized by: 1. Rotor and pump chamber, between the rotor and the rotor where there is a certain gap Hebei Roots vacuum, do not touch, do not need oil lubrication. 2. The rotor has a good use of geometric symmetry Hebei Roots vacuum, can improve the speed, which can produce a compact, high pumping speed pump. 3. When the pump vibration, volume, volume utilization factor = 0.5. 4. Does not occur in the pump chamber as a mechanical vacuum pump as compression and, therefore, it does not need to vent. That is why, in addition to pumping condensable vapors. 5. Start fast, able to reach the ultimate vacuum in a short time. Low power, low operation and maintenance costs. 6. Roots pump over a wide pressure range (1000Pa ~ 1Pa) have great Roots vacuum pumping speed, can quickly exhaust a sudden release of gas, make up the pumping speed when the diffusion pump and mechanical seal pumps (1000Pa ~ 1Pa) are small defects. Therefore, it is most suitable for use booster. Hebei Roots Roots vacuum pump uses _ _ Zhucheng East Machinery Co., Ltd. is provided by John Han Machinery Co., Ltd. Zhucheng East.
