VACUUM PUMPS OF SPIRAL SLICE Style Use scope The single stage oil cycle vacuum pumps of spiral slice sort of series SYF and double stage oil cycle vacuum pumps of spiral slice form on the series of 2SYF are important products for abstracting the fuel from obturational container to obtain vacuum. The double stage vacuum pumps of spiral slice style of your series of 2SYF utilized for abstracting to get vacuum yet again on the basis of single stage pumps. It might make the technique achieve the highest point vacuum. Characteristics (1) The design and style of preventing oil-returning The passage of gasoline admission is specially built to avoid the returning of pumps oil delivering the abstracted container and pipeline just after the pumps stop working. (2) The style and design of environmental protection The design of built-in device of mist eliminating, and set oil-gas seperator within the vent, each manage the pollution of oil throughout the course of exhausting efficiently. (three) Aluminum alloy casing of electric machinery The electrical machinery use aluminum alloy casing, it has large efficiency of heat emission, and ensure long time standard operation continously, furthermore, it has greater appearance quality. (4) The design of integration The electric machinery and pumps utilize the design of integration making the items extra significant and affordable. (5) Big starting up up second Our product types specially aiming on the atmosphere of very low temperature and electric pressure. ensuring the machine starts typically at lower temperature of winter environment(?Y-5??) and very low electrical stress(?Y180V).
