VACUUM PUMPS OF SPIRAL SLICE Variety Use scope The single stage oil cycle vacuum pumps of spiral slice sort of series SYF and double stage oil cycle vacuum pumps of spiral slice type with the series of 2SYF are critical equipment for abstracting the fuel from obturational container to have vacuum. The double stage vacuum pumps of spiral slice type in the series of 2SYF applied for abstracting to get vacuum yet again within the basis of single stage pumps. It can make the program accomplish the highest level vacuum. Characteristics (one) The layout of avoiding oil-returning The passage of gas admission is specially intended to reduce the returning of pumps oil delivering the abstracted container and pipeline just after the pumps quit operating. (two) The design of environmental protection The style of built-in device of mist eliminating, and set oil-gas seperator to the vent, both handle the pollution of oil throughout the course of exhausting effectively. (three) Aluminum alloy casing of electric machinery The electric machinery use aluminum alloy casing, it has higher efficiency of heat emission, and guarantee very long time typical operation continously, it also has much better look high quality. (4) The layout of integration The electrical machinery and pumps use the layout of integration building the solutions much more severe and affordable. (5) Massive starting up up minute Our solution designs specially aiming at the surroundings of low temperature and electric stress. making certain the machine starts usually at decrease temperature of winter natural environment(?Y-5??) and reduced electric strain(?Y180V).
