 Roots vacuum pump Notes 1, should first understand pumped gas composition, gas, whether it contains condensable vapors, whether the particles of dust, corrosive or without Leybold, if corrosive please use stainless steel pump. When selecting a vacuum pump, need to know the gas composition, select the appropriate pump for pumped gas. If the gas contains vapor, particles, and corrosive gases, should consider the installation of auxiliary equipment at the inlet of pipeline pump, such as a condenser, dust and the like. 2, the working pressure Roots vacuum pump vacuum equipment should meet the ultimate vacuum and pressure requirements. Such as: a vacuum drying process requirements 10mmHg (absolute pressure) working pressure Leybold WAU2001 Roots pump maintenance, use of vacuum pressure limits at least 2mmHg, preferably less than 1mmHg. Usually chosen higher than the ultimate pressure of the pump working pressure of the vacuum apparatus to half an order of magnitude. 3, the correct choice of the operating point of Roots vacuum unit. Roots vacuum pump unit normal operating range for maximum suction pressure - the ultimate pressure × 5. Example: the normal operating range JZJ2B150-2.1 Roots water ring vacuum pump is: 6000Pa ~ 125Pa, the main scope of work after normal working pressure range of the pump is turned on Leybold WSU1001 Roots pump repair, the unit within the scope of this work optimum efficiency. 4, the vacuum pump in its work under pressure, should be able to discharge all the amount of vacuum equipment, process gas produced. 5, according to the actual working conditions appropriate choice of unit configuration. For example: The maximum pumping speed and ultimate pressure JZJ2B300-4.1 JZJ2B300-2.1 units and units are the same, the difference is the scope of their work and the power consumption, the normal operating range JZJ2B300-4.1 unit for 2000Pa ~ 125Pa, The normal operating range for the unit JZJ2B300-2.1 5000Pa ~ 125Pa, the normal operating range JZJ2B300-2.1 crew obviously wider, but its power consumption is greater. If you can confirm that the system is working pressure pumping <2000Pa when Leybold WSU251 Roots pump maintenance, should be preferred JZJ2B300-4.1 unit to save energy. Roots vacuum pump unit (1), Roots vacuum pump should be installed in a dry, airy place outstanding and cleaning. (2), Roots vacuum ambient temperature 5-40 ℃. (3), Roots vacuum pump should be level device, which should leave plenty around the point, usually easy to view, maintain conservation. Facilitate assembly and disassembly. (4), after turning on the power steering motor rotation should be consistent with the arrow shown on the pump. (5), convergence is pipeline pumping containers should be cleaned. Free of impurities and other foreign matter, should not be less than the pump inlet aperture diameter, length should be short, to ensure that they have the ability to meet the communications and navigation, convergence should be sealed and not leaking pipes. (6) has been pumping gas should be free of particulate solids into the pump chamber. (7), Roots vacuum pump should be installed before the pump convergence elastic tube to cut before the pump caused a sensation. (8), it is necessary to interlock the electrical equipment protection device, the current stage pump Roots pump stops working when it is necessary to stop together. (9), a small pump can be started directly, large pump shall be located launcher.
