Magnetic drive Roots vacuum pump successfully developed

By Taizhou City, Zhejiang Hing Wah Vacuum Equipment Manufacturing Co., Ltd. developed magnetic transmission Roots vacuum pump, after 18 months of continuous trial operation, reliable, stable, recently passed the expert assessment. After more than 20 years of improvement, the main performance of Roots vacuum pump such as the ultimate pressure, aspiration rate, energy consumption, zero flow compression ratio and other indicators have reached or approached the international advanced level, but the vibration, noise, shaft seal oil leakage and other indicators and Foreign advanced level is still slightly behind the gap, mainly in the shaft seal there is the phenomenon of oil spills, waste of resources, contaminated sites, seriously affecting the normal production. To this end, the company after more than three years of research, the successful development of China's first industrial magnetic drive Roots vacuum pump. The inner and outer magnets of the magnetic transmission device of the pump adopt NdFeB materials, and utilize the magnetic over-torque characteristic to complete the power transmission between the motor and the pump. The pump main shaft and the inner magnet are completely shielded by the non-metallic isolation sleeve and have no shaft seal to realize the dynamic Zero leakage transmission. Compared with the use of rigid coupling, magnetic transmission Roots pump start without impact, stable operation. At the same time due to the use of anti-corrosion materials, suitable for chemical industry corrosive media requirements. At present, the maximum power of the pump up to 2500 l / s, more than 60 units have been used in the enterprise.
