VACUUM PUMPS OF SPIRAL SLICE Variety Use scope The single stage oil cycle vacuum pumps of spiral slice variety of series SYF and double stage oil cycle vacuum pumps of spiral slice type from the series of 2SYF are vital equipment for abstracting the gasoline from obturational container to get vacuum. The double stage vacuum pumps of spiral slice variety of your series of 2SYF employed for abstracting to have vacuum again on the basis of single stage pumps. It may make the system accomplish the highest point vacuum. Functions (1) The design and style of stopping oil-returning The passage of fuel admission is specially made to avoid the returning of pumps oil delivering the abstracted container and pipeline right after the pumps end operating. (two) The design and style of environmental safety The design of built-in device of mist getting rid of, and set oil-gas seperator to the vent, each cope with the pollution of oil during the course of exhausting efficiently. (3) Aluminum alloy casing of electrical machinery The electric machinery use aluminum alloy casing, it has large efficiency of heat emission, and ensure long time regular operation continously, it also has much better appearance good quality. (4) The layout of integration The electrical machinery and pumps use the design of integration producing the goods more serious and realistic. (5) Large starting up up minute Our solution types specially aiming with the surroundings of very low temperature and electric strain. ensuring the machine begins usually at lower temperature of winter environment(?Y-5??) and minimal electric strain(?Y180V).
