VACUUM PUMPS OF SPIRAL SLICE Variety 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 from the series of 2SYF are critical gear for abstracting the gas from obturational container to obtain vacuum. The double stage vacuum pumps of spiral slice sort on the series of 2SYF employed for abstracting to have vacuum once more on the basis of single stage pumps. It could possibly make the technique accomplish the highest level vacuum. Characteristics (1) The layout of avoiding oil-returning The passage of gasoline admission is specially created to stop the returning of pumps oil delivering the abstracted container and pipeline after the pumps end operating. (2) The design and style of environmental protection The design and style of built-in device of mist eliminating, and set oil-gas seperator to the vent, each handle the pollution of oil in the course of the program 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 make sure long time standard operation continously, it also has better look top quality. (4) The style and design of integration The electric machinery and pumps make use of the style and design of integration creating the goods more extreme and acceptable. (five) Major starting up up second Our solution types specially aiming at the surroundings of minimal temperature and electrical strain. making sure the machine commences usually at reduce temperature of winter atmosphere(?Y-5??) and low electrical strain(?Y180V).
