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 style with the series of 2SYF are essential tools for abstracting the gas from obturational container to obtain vacuum. The double stage vacuum pumps of spiral slice style with the serie of 2SYF used for abstracting to have vacuum once again over the basis of single stage pumps. It could make the procedure reach the highest stage vacuum.
Characteristics
(1)The style of stopping oil-returning
The passage of gas admission is specially created to prevent the returning of pumps oil delivering the abstracted container and pipeline soon after the pumps prevent operating.
(two)The style and design of enviromental safety
The design of built-in device of mist eliminating, and set oil-gas seperator on the vent, each handle the pollution of oil in the course of the program of exhausting effectively.
(three) Aluminium alloy casing of electric machinery
The 
electric machinery use aluminium alloy casing, it’s high efficiency of heat emission, and guarantee long time standard operation continously, it also has much better physical appearance excellent.
(four) The style of integration
The electric machinery and pumps use the design of integration making the solutions additional significant and sensible.
(five) Major starting up moment
Our product models specially aiming in the enviroment of low temperation and electrical pressure. ensuring the machine starts typically at lower temperatue of winter enviroment(?Y-5??) and low electric stress(?Y180V).
