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 style on the series of 2SYF are important tools for abstracting the gas from obturational container to obtain vacuum. The double stage vacuum pumps of spiral slice form from the series of 2SYF utilised for abstracting to obtain vacuum yet again to the basis of single stage pumps. It can make the technique achieve the highest level vacuum. Capabilities (1) The style of stopping oil-returning The passage of gas admission is specially built to prevent the returning of pumps oil delivering the abstracted container and pipeline right after the pumps cease working. (two) The layout of environmental safety The design of built-in device of mist eliminating, and set oil-gas seperator about the vent, the two manage the pollution of oil through the program of exhausting efficiently. (3) Aluminum alloy casing of electrical machinery The electric machinery use aluminum alloy casing, it has higher efficiency of heat emission, and assure very long time ordinary operation continously, in addition, it has much better look top quality. (4) The layout of integration The electrical machinery and pumps use the layout of integration generating the products extra extreme and fair. (5) Huge starting up up moment Our item models specially aiming at the natural environment of reduced temperature and electrical pressure. guaranteeing the machine commences commonly at lower temperature of winter setting(?Y-5??) and reduced electrical pressure(?Y180V).
