干式真空泵是干式压缩泵,不会发生润滑油接触泵送介质的现象,因此可以产生无油真空。根据应用要求,莱宝可以提供不同类型和工作原理的干式压缩真空泵:膜片泵DIVAC,涡旋泵SCROLLVAC,螺杆泵SCREWLINE、DRYVAC和LEYVAC。
SCREWLINE是干式压缩螺杆真空泵。纯粹的风冷版,是结**用螺杆内部油路冷却和外壳的风扇冷却。如果安装于空调房内则可以选水冷版以降低空调负荷。此外还有ATEX认证版及抽纯氧气版本(O2)。
Dry Compressing Vacuum Pumps
The dry compressing screw vacuum pumps from the SCREWLINE SP family were developed in view of the special requirements of industrial applications. The innovative, modular design of the SCREWLINE allows these pumps to be used in all cases where reliable, compact and low maintenance vacuum technology is demanded. SCREWLINE pumps are suited for all applications with higher requirements regarding the backing pump, like for example in processes involving high particle counts or in the hard production area. The dry compressing SCREWLINE pumps are an ideal alternative to conventional oil-sealed vacuum systems.
■ High system availability ■ Minimum maintenance complexity ■ High vapor tolerance and particle compatibility ■ Simple on-site cleaning ■ Environment compliant production ■ Low operating and investment costs
■ Industrial furnaces / heat treatment (hardening, annealing, sintering, carburization, melting) ■ Coating technology ■ Metallurgical systems ■ Drying processes ■ Load lock chambers ■ Degassing ■ Research and development ■ Lamps and tubes manufacture ■ Automotive industry ■ Space simulation ■ Electrical engineering ■ Packaging technology■ Leak detection
■ Environment friendly, low operating costs - no production of contaminated waste oil, no waste disposal costs ■ Minimum downtimes, maximum availability and maximum ruggedness through an application optimized design ■ Reduced process time in batch operation or short cycles - high effective pumping speed also at low intake pressures ■ Low investment costs ■ Cost optimized product - modular accessories meeting the demands of challenging process requirements ■ High versatility degree - the modular concept allows a simple adaptation of the pumping speed up to 2000 m3/h in combination with Roots pumps - universal flanges facilitate an easy integration and flexible adaptation to any system■ Pump chamber - simple to disassemble for cleaning on-site ■ Extended maintenance intervals, low servicing complexity - only an annual gear oil change is necessary ■ Maintenance friendly - quick and easy accessibility to all servicing points
