ZJP series Roots vacuum pump is a structurally sound positive displacement Roots vacuum pump manufacturer, and its biggest advantage is a higher pumping speed at low inlet pressure, and can achieve a relatively high ultimate vacuum. Since the pump is used directly in the exhaust of the main parts such as axle housing between the rotor and the cover is no relative movement contacting Roots vacuum use, so stable ZJP series Roots vacuum pump performance, long life, low maintenance costs. The current vacuum pump is widely used in metallurgy, vacuum welding, vacuum casting, vacuum coating, vacuum dynamic tests and chemical and pharmaceutical, manufacturing and other electric vacuum casting process in vacuum pump can be achieved within the vacuum range. 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 wholesale, smooth operation and between the rotor and the rotor. Each gap between the housing, no lubrication, low friction losses, can greatly reduce the driving power, enabling high speed; 3, the pump chamber without Roots vacuum sealing and lubrication oil, can reduce oil vapor vacuum system pollution; 4, the pump chamber without compression, 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 refining, 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 vacuum pump manufacturers supply, Zhucheng East Han Machinery Co., Ltd., Zhengzhou Roots vacuum provided by Han Machinery Co., Ltd.
