Four diesel generators operating error: diesel cold start after Meng Meng throttle if the throttle, the sharp rise in diesel generator speed, it will cause some friction surface on the unit due to dry friction produces severe wear. In addition, H-throttle piston, connecting rod and crankshaft receiving power changes, causing severe impact, easily damaged parts. Diesel generators operate five errors: In the cooling water shortage or cooling water, oil temperature is too high operating diesel generator cooling water shortage will reduce its cooling effect, due to the lack of effective cooling diesel engine overheating; cooling water, oil The oil temperature is too high, can cause overheating diesel. At this diesel generator cylinder head, the main heating cylinder liner, piston and valve components, such as load, such as a sharp decline in strength, toughness, and other mechanical properties, so that deformation of parts increases, decreases with the gap between the parts, accelerated engine wear so serious that it cracks, stuck mechanical failure. Diesel generator overheating will deteriorate diesel combustion process, so that the injector malfunction, poor atomization, coke increased. What need to consider when buying a diesel generator set Zhangzhen Yi:? First, plan to make the number of existing and proposed expansion of the load with diesel generators, which determines the required output power of the unit. Diesel generators are rated active power output indication KW, while some also marked gaze at power KVA, the power factor of 0.8 generators are usually designed so that KW is 0.8 KVA. Technical indicators mentioned above is based on an objective evaluation of the diesel generator set, a careful analysis and comparison. Also consider the altitude, the annual climate change, the noise impact on the environment and other natural conditions. Select the best cost-effective products to meet the needs. Please talk about the UPS systems and diesel generators connected with problems. Zhangzhen Yi: The main problem is the higher harmonic component of the input current UPS. It's pre-rectifier harmonic current generated generator rental trailer, with the input current into the armature windings in synchronous generators to power the unit, and the armature field interference. So that the generator output voltage waveform distortion, also appeared higher harmonic components. Such a voltage supply UPS, if one of the higher harmonic component is sufficient to disrupt the work of UPS tracks the input voltage generator PLL circuit lease, the UPS can not turn the inverter output. Diesel generator sets and therefore it is not connected with the. Of course, the choice of UPS output power is several times larger than the diesel generator rental generator manufacturer, a powerful magnetic field to synchronize the generator armature disturbed harmonic current of relatively small, and thus the output voltage of the high-order harmonic wave component decreased to resolve UPS mating, is a way, but too uneconomical. A better approach is to choose the former level is the active power factor correction circuit PFC or IGBT rectifier UPS products. Their input current harmonics are less than 5%, is very conducive and diesel generator sets mating. For installed UPS, electric energy may be the size of the mass analyzer detects the input current of each higher harmonic component of the load at the time of its work, for diagnosis as to filter out interference large passive filter harmonic components, in order to achieve and diesel generator sets mating.
