ZJ Roots vacuum pump, thanks to adopt "O" ring seal between the CNC machining center, vacuum pump and side 盖罗茨 manufacturers, side cover and cover, cylindrical pin positioning Roots vacuum where the most expensive parts exchange of good performance, easy maintenance, pump with an air inlet, the structural design of the three exhaust ports, user-friendly installation. Roots pumps can not be used, only the series before the pump to use, you can choose screw, seal pumps, liquid ring pump as a backing pump Roots vacuum wholesale price, it is worth mentioning, was elected with a screw pump, liquid ring pumps When as a backing pump, especially for the occasion in addition to a large number of suspicious smoke gases. Roots vacuum pump structural characteristics: 1, in a wide pressure range has a higher pumping speed; 2, the rotor has a good geometric symmetry, so little vibration Roots vacuum pump, smooth running between the rotor and the rotor and the housing. the gap between both, no lubrication, small friction loss, can greatly reduce the driving power, enabling high speed; 3, the pump chamber without sealing and lubrication oils can reduce the pollution of oil vapor vacuum system; 4, the pump cavity uncompressed, no exhaust valve structure is simple, compact, and to be pumping gas in the dust and water vapor insensitive; 5, Roots vacuum pumps at home and abroad in recent years has been rapid development in the metallurgical, petrochemical. , 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 pump where the cheapest _ _ Zhucheng East Han Machinery Co., Roots vacuum provided by the Zhucheng East Han Machinery Co.
