Brush a good sign generator brushes should be a good marker for the use of performance: a commutator or collector ring surface can quickly form a layer of uniform, moderate and stable oxide film. b brushless long life, do not wear commutator or collector ring. c brushless commutation and has good current collecting performance, the spark suppressed within the allowable range of the generator set, and the energy loss is small. d Brush runtime Yuchai diesel generator set, but the heat and noise of small diesel generator set manufacturers, assembly and reliable, is not damaged. Generators after use and management. 1. After the generator shut down, pay attention to check whether the turbines' three drain "phenomenon low-noise generators, oil, fuel, coolant 2. Turn off the fuel valve 3. Turn off the engine room air intake and exhaust facilities 4. Turn off the generator 5. Turn off the breaker output power control panel key switch, remove the key, keep longer 6. turbine standstill or maintenance unit, you must start the generator battery negative cable removed, if necessary, should be exhausted fuel and cooling fluid. Low-noise generators, Shijiazhuang generators, power is provided by Yama Yama Weifang Power Equipment Manufacturing Co., Ltd. Yama Weifang Power Equipment Manufacturing Co., Ltd.
