VACUUM PUMPS OF SPIRAL SLICE Sort 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 important equipment for abstracting the gasoline from obturational container to acquire vacuum. The double stage vacuum pumps of spiral slice kind from the series of 2SYF used for abstracting to have vacuum once more to the basis of single stage pumps. It may possibly make the method reach the highest point vacuum. Options (1) The design and style of preventing oil-returning The passage of gas admission is specially designed to avoid the returning of pumps oil delivering the abstracted container and pipeline right 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 to the vent, the two manage the pollution of oil during the course of exhausting effectively. (three) Aluminum alloy casing of electric machinery The electrical machinery use aluminum alloy casing, it has substantial efficiency of heat emission, and assure long time standard operation continously, in addition, it has far better physical appearance high quality. (4) The style of integration The electrical machinery and pumps use the design of integration producing the items far more serious and fair. (5) Big commencing up second Our solution models specially aiming in the surroundings of lower temperature and electrical pressure. guaranteeing the machine begins normally at reduced temperature of winter environment(?Y-5??) and low electrical pressure(?Y180V).
