Roots pump main features:? Speed, high volumetric efficiency. ? Simple structure, operation, and maintenance. ? Rotor is locked, no axial moving string phenomenon. ? High-precision gear and good dynamic balance, low noise, smooth operation. ? Oil-free pump chamber structure, suitable for general air extraction and various special gases. ? Compared to other mechanical vacuum pump, energy-saving effect is remarkable. ? Before the pump can be used with all types of facilities, can be widely used in various processes range. ? May be air and water ways to meet different working conditions. Roots vacuum pump structural characteristics: 1, in a wide pressure range has a higher pumping speed; 2, the rotor has a good geometrical symmetry Roots vacuum pump wholesale, so little vibration, smooth operation and between the rotor and the rotor. Roots vacuum gap between the housing are direct, no lubrication, low friction losses, can greatly reduce the driving power, enabling high speed; 3, the pump chamber without sealing and lubrication oil, can reduce oil vapor vacuum system pollution; 4, Roots vacuum pump chamber uncompressed production and supply, no exhaust valve structure is simple, compact, and has been pumping gas for dust and water vapor insensitive; 5, Roots vacuum pumps at home and abroad in recent years, has been rapid development in the smelting, petrochemicals, electrical, electronics and other industries has been widely used. Roots vacuum lifting and transportation Note 1. Roots vacuum machine lifting methods should be appropriate. 2. lifting capacity spreader and lifting equipment to adapt to the weight of the vacuum pump. 3. spreader to be long enough that the spreader angle is less than 90 degrees. 4. Select the appropriate lifting points. 5. Place the spreader must be correct in order to ensure smooth lifting. 6. Check the integrity of the spreader. 7. Make sure the lifting capacity of lifting equipment! Roots vacuum pump production and supply, Zhucheng East Han Machinery Co., Ltd., Hangzhou Roots vacuum provided by Han Machinery Co., Ltd.
