Gas-cooled Roots pumping main structure: Bearings: a fixed axis uses double row angular contact ball bearings Hebei Roots vacuum use, retractable side uses a high load capacity of roller bearings. These bearings can withstand high speed and load Hebei Roots pump manufacturer and supplier 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. The main features of Roots vacuum pumps: Roots pump 1. All specifications are cooled by air, without circulating cooling water system. 2. Roots vacuum filling machine structure Hebei wholesale phone, no seal design eliminates failure points Roots vacuum pump tightness improve, more durable, high purity extraction / radioactive gas. 3. The inverter used in conjunction with a dedicated, can make a maximum pumping speed increased by 100%. The vertical flow horizontal flow easy to change.
