To above configuration, we will use 2 units of 3000QGFA gas engine generator sets and 1 unit of SP4600 diesel generator set to set up the power plant. Each unit of generator is installed on its rigid common base, and engine and generator are coupled with flexible coupling to connect, common bases are installed on foundation by using vibration reducing dampers. Heat generated in operation will be taken away by cooling system. Closed cycled cooling system is adopted with water-air cooling exchange method, and it is arranged together with lube oil pre supplying pump, fuel supply pump (with filter) and piping, valves, and they are connected with generator with flexible hose pipe. At both the inlet and exhaust let there are filter and silencers.
The generator sets are controlled by management & control system to provide user friendly interface with engine and operation. Most parts are produced by our producer, and so we can guarantee high quality, timely supply and life long supply of parts.
The power plant includes generator sets, fuel transfer and supply system, cooling system, electric system, exhaust system, power plant unit management control system (including alarming system).
