Problems solved by technology

[0002] When the diesel generator set is not running at full load or just started, the fan is running at full speed, which causes a waste of power and an increase in fuel consumption of the diesel generator set, and takes away a lot of heat from the engine, especially in extremely cold environments. When the unit is started, the fan is running at full speed, and the engine cannot be warmed up effectively, which accelerates the wear of the engine, reduces the service life of the diesel generator set, and causes a waste of customer resources

Abstract

The invention relates to the technical field of diesel generating sets, in particular to a fan speed-regulating device and speed-regulating method for a diesel generating set. The fan speed-regulatingdevice comprises a crankshaft belt wheel, an electromagnetic clutch, a fan, a water temperature sensor and a controller, wherein the crankshaft belt wheel is connected on an engine crankshaft of a diesel generating set; a driven end of the electromagnetic clutch is connected with a rotary shaft of the fan; a clutch belt wheel is arranged on the drive end of the electromagnetic clutch; the crankshaft belt wheel is connected with the clutch belt wheel through belt transmission; a water temperature sensor used for detecting temperature of water or inter-cooled water of an engine cylinder sleeveis arranged on the engine; and the controller is separately connected with the electromagnetic clutch and the water temperature sensor. The fan speed-regulating device can effectively reduce oil consumption, reduces waste gas emission of the generating set, prolongs the service life of the generating set, brings considerable fuel oil cost reduction, and meets energy-saving emission-reducing needs.
