VACUUM PUMPS OF SPIRAL SLICE Type Use scope The single stage oil cycle vacuum pumps of spiral slice kind of series SYF and double stage oil cycle vacuum pumps of spiral slice type in the series of 2SYF are necessary tools for abstracting the gasoline from obturational container to have vacuum. The double stage vacuum pumps of spiral slice type in the series of 2SYF made use of for abstracting to get vacuum once more around the basis of single stage pumps. It may possibly make the method realize the highest level vacuum. Attributes (1) The layout of preventing oil-returning The passage of gasoline admission is specially designed to avert the returning of pumps oil delivering the abstracted container and pipeline just after the pumps cease working. (2) The design of environmental protection The design of built-in gadget of mist eliminating, and set oil-gas seperator within the vent, each handle the pollution of oil through the course of exhausting efficiently. (3) Aluminum alloy casing of electric machinery The electrical machinery use aluminum alloy casing, it has substantial efficiency of heat emission, and guarantee very long time regular operation continously, additionally, it has superior visual appeal excellent. (4) The design of integration The electric machinery and pumps use the style of integration building the products much more extreme and reasonable. (5) Huge starting up moment Our product patterns specially aiming at the setting of lower temperature and electric pressure. making certain the machine starts normally at reduce temperature of winter surroundings(?Y-5??) and reduced electric pressure(?Y180V).
