摘要： A vacuum system has a condenser and a root vacuum pump set, wherein the condenser is an independent inlet condenser set connected to a generator including an air cooling power generator condenser. A pressure sensor is installed on the independent inlet condenser set for detecting a first input pressure. Air outputted from the independent inlet condenser set is compressed by the root vacuum pump set. A backing pump receives an air outputted from the root vacuum pump set through an output pipe. A bypass pipe is connected between an output end of the root vacuum pump set and a vapor-liquid separator connected to the backing pump. A central controller serves to receive the first input pressure and determine to control the air from the root vacuum pump set to be outputted to the output pipe or the bypass pipe by a control valve.
