VACUUM PUMPS OF SPIRAL SLICE Form Use scope The single stage oil cycle vacuum pumps of spiral slice type of series SYF and double stage oil cycle vacuum pumps of spiral slice type with the series of 2SYF are important tools for abstracting the gasoline from obturational container to obtain vacuum. The double stage vacuum pumps of spiral slice style in the series of 2SYF applied for abstracting to acquire vacuum yet again over the basis of single stage pumps. It could make the process attain the highest point vacuum. Options (1) The design and style of avoiding oil-returning The passage of gas admission is specially built to prevent the returning of pumps oil delivering the abstracted container and pipeline soon after the pumps end operating. (2) The layout of environmental protection The style of built-in device of mist eliminating, and set oil-gas seperator to the vent, the two manage the pollution of oil all through the course of exhausting efficiently. (three) Aluminum alloy casing of electrical machinery The electric machinery use aluminum alloy casing, it’s large efficiency of heat emission, and be certain very long time normal operation continously, furthermore, it has much better physical appearance top quality. (4) The style and design of integration The electrical machinery and pumps use the style and design of integration building the products more significant and reasonable. (five) Massive starting up moment Our solution models specially aiming in the natural environment of minimal temperature and electrical pressure. making sure the machine commences ordinarily at lower temperature of winter natural environment(?Y-5??) and reduced electric pressure(?Y180V).
