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 kind in the series of 2SYF are necessary equipment for abstracting the gasoline from obturational container to get vacuum. The double stage vacuum pumps of spiral slice variety of the series of 2SYF utilised for abstracting to get vacuum again on the basis of single stage pumps. It may make the system obtain the highest point vacuum. Functions (one) The design and style of avoiding oil-returning The passage of gas admission is specially made to avoid the returning of pumps oil delivering the abstracted container and pipeline soon after the pumps halt operating. (2) The layout of environmental safety The style of built-in device of mist getting rid of, and set oil-gas seperator over the vent, the two cope with the pollution of oil throughout the course of exhausting efficiently. (3) Aluminum alloy casing of electric machinery The electric machinery use aluminum alloy casing, it has large efficiency of heat emission, and ensure long time typical operation continously, it also has much better appearance good quality. (4) The layout of integration The electrical machinery and pumps make use of the design of integration producing the goods much more serious and realistic. (5) Large starting up moment Our merchandise types specially aiming with the surroundings of very low temperature and electrical strain. making certain the machine begins usually at reduce temperature of winter environment(?Y-5??) and minimal electric strain(?Y180V).
