◆ 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 type of the series of 2SYF are essential equipment for abstracting the gas from obturational container to get vacuum. The double stage vacuum pumps of spiral slice type of the serie of 2SYF used for abstracting to get vacuum again on the basis of single stage pumps. It can make the system achieve the highest point vacuum.
◆ Features
(1) The design of preventing oil-returning
The passage of gas admission is specially designed to prevent the returning of pumps oil delivering the abstracted container and pipeline after the pumps stop operating.
(2) The design of enviromental protection
The design of built-in device of mist eliminating, and set oil-gas seperator on the vent, both deal with the pollution of oil during the course of exhausting efficiently.
(3) Aluminium alloy casing of electric machinery
The electric machinery use aluminium alloy casing, it has high efficiency of heat emission, and ensure long time normal operation continously, it also has better appearance quality.
(4) The design of integration
The electric machinery and pumps use the design of integration making the products more severe and reasonable.
(5) Big starting up moment
Our product designs specially aiming at the enviroment of low temperation and electric pressure. ensuring the machine starts normally at lower temperatue of winter enviroment(≥-5℃) and low electric pressure(≥180V)
