VACUUM PUMPS OF SPIRAL SLICE Form 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 form on the series of 2SYF are crucial tools for abstracting the gas from obturational container to acquire vacuum. The double stage vacuum pumps of spiral slice sort on the series of 2SYF applied for abstracting to have vacuum once again on the basis of single stage pumps. It might make the method reach the highest level vacuum. Characteristics (1) The style and design of avoiding oil-returning The passage of fuel admission is specially designed to protect against the returning of pumps oil delivering the abstracted container and pipeline immediately after the pumps end operating. (two) The style of environmental protection The layout of built-in device of mist getting rid of, and set oil-gas seperator within the vent, each deal with the pollution of oil through the program of exhausting effectively. (3) Aluminum alloy casing of electrical machinery The electric machinery use aluminum alloy casing, it’s higher efficiency of heat emission, and make certain long time standard operation continously, in addition, it has improved look top quality. (four) The layout of integration The electrical machinery and pumps use the design and style of integration building the goods far more serious and affordable. (five) Big starting up moment Our product models specially aiming on the natural environment of minimal temperature and electrical strain. making sure the machine starts normally at decrease temperature of winter surroundings(?Y-5??) and lower electrical pressure(?Y180V).
