It can operate under high suction pressure for lighting, electronics, optics, semiconductor coating, sputtering, ion plating, liquid crystal injection, vacuum drying, freeze-drying, vacuum degassing, vacuum heat treatment furnace, sintering furnace, brazing furnace analysis instruments, leak detection equipment, CO2 laser equipment

　　ULVAC Aifa Technology NB2400B Roots Vacuum Pump Maintenance and RepairThe main reasons for abnormal noise include the following: motor noise: fan noise is generally large, and according to analysis, it should be caused by deformation of plastic fans; The second issue is the bearing noise caused by the use of low-quality bearings. Rotor collision: collision noise between rotors, rotors and pump bodies, and rotors and side covers. The main reasons for this are: insufficient stiffness of the shaft, radial displacement of the rotor and gears on the shaft, excessive or insufficient gear clearance, and excessive axial clearance of the bearings. Gear noise: Factors that affect gear noise include not only the machining accuracy of the gear itself, but also the parallelism of the two rotor shafts on which the gear is installed. Bearing noise: In addition to the accuracy of the bearing itself, inadequate design may also cause an increase in bearing noise, such as excessive interference fit in the installation of the inner and outer rings of the bearing, insufficient shaft stiffness, insufficient lubricating oil supply, and contamination by dust, water, corrosive gases, and liquids. Abrasive particles entering: A large amount of abrasive particles generated during operation enter the Roots pump, causing mechanical wear. Installation method: Is the installation method of the Roots pump correct and is there any tilting. In summary, the abnormal noise of Roots pumps may be caused by various factors. In order to reduce noise and wear, regular maintenance and inspection should be carried out
