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 kind on the series of 2SYF are crucial gear for abstracting the gasoline from obturational container to acquire vacuum. The double stage vacuum pumps of spiral slice sort in the series of 2SYF used for abstracting to have vacuum once more over the basis of single stage pumps. It can make the program achieve the highest stage vacuum. Features (1) The layout of stopping oil-returning The passage of gasoline admission is specially made to avert the returning of pumps oil delivering the abstracted container and pipeline soon after the pumps prevent operating. (two) The style and design of environmental safety The design of built-in device of mist eliminating, and set oil-gas seperator over the vent, the two deal with the pollution of oil throughout the course of exhausting effectively. (3) Aluminum alloy casing of electric machinery The electrical machinery use aluminum alloy casing, it has high efficiency of heat emission, and be certain long time standard operation continously, in addition, it has greater physical appearance top quality. (4) The design and style of integration The electric machinery and pumps use the style of integration producing the merchandise additional extreme and reasonable. (5) Large starting up up second Our merchandise models specially aiming on the surroundings of very low temperature and electric stress. guaranteeing the machine begins usually at reduced temperature of winter environment(?Y-5??) and low electrical pressure(?Y180V).
