VACUUM PUMPS OF SPIRAL SLICE Variety 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 sort from the series of 2SYF are critical tools for abstracting the fuel from obturational container to get vacuum. The double stage vacuum pumps of spiral slice variety with the series of 2SYF made use of for abstracting to get vacuum once again over the basis of single stage pumps. It might make the method reach the highest point vacuum. Attributes (one) The design and style of avoiding oil-returning The passage of gasoline admission is specially created to prevent the returning of pumps oil delivering the abstracted container and pipeline soon after the pumps halt working. (2) The style and design of environmental protection The style and design of built-in device of mist eliminating, and set oil-gas seperator on the vent, both take care of the pollution of oil all through the course of exhausting efficiently. (3) Aluminum alloy casing of electrical machinery The electrical machinery use aluminum alloy casing, it has high efficiency of heat emission, and be certain long time typical operation continously, in addition, it has much better visual appeal quality. (4) The design of integration The electric machinery and pumps make use of the layout of integration building the items additional extreme and reasonable. (5) Big starting up up second Our product or service types specially aiming in the natural environment of very low temperature and electric strain. ensuring the machine starts usually at decrease temperature of winter environment(?Y-5??) and lower electrical pressure(?Y180V).
