VACUUM PUMPS OF SPIRAL SLICE Style Use scope The single stage oil cycle vacuum pumps of spiral slice form of series SYF and double stage oil cycle vacuum pumps of spiral slice kind of the series of 2SYF are vital equipment for abstracting the gasoline from obturational container to acquire vacuum. The double stage vacuum pumps of spiral slice sort with the series of 2SYF used for abstracting to get vacuum once more within the basis of single stage pumps. It could possibly make the system realize the highest stage vacuum. Characteristics (1) The style of avoiding oil-returning The passage of fuel admission is specially intended to stop the returning of pumps oil delivering the abstracted container and pipeline following the pumps quit operating. (2) The design of environmental safety The design of built-in gadget of mist eliminating, and set oil-gas seperator to the vent, both cope with the pollution of oil throughout the course of exhausting effectively. (3) Aluminum alloy casing of electrical machinery The electric machinery use aluminum alloy casing, it has high efficiency of heat emission, and guarantee long time normal operation continously, additionally, it has greater look high quality. (4) The layout of integration The electric machinery and pumps utilize the style and design of integration creating the solutions much more significant and reasonable. (five) Large beginning up moment Our solution patterns specially aiming with the atmosphere of lower temperature and electrical strain. ensuring the machine starts typically at decrease temperature of winter natural environment(?Y-5??) and very low electric pressure(?Y180V).
