Diesel generator set fuel use caution fuel generator is the power source, is the main factor causing the generator failure, clean fuel free of water and impurities is very important, otherwise it will cause severe injection pump and nozzle wear or damage. Fuel quality problems in our country has been caused by generators and reduce the life of the main reason for the failure, so the use of imported generators make use of high-quality low-sulfur fuel Cummins generator maintenance, the case can not meet the requirements of the pipeline route can be modified in the water front splitter plus level coarse filter or water separator, so as not to affect the generator output power level of subject selection filter. In the case of low-grade fuel fuel tank must be cleaned regularly, otherwise easily due to the poor quality of fuel in the tank containing water and impurities, will be in the tank wall and the bottom of the junction area of ??diesel generator maintenance, resulting in the case of long-term plot knot not cleaned Mud shedding skin, work into the fuel line generator maintenance, resulting in lines or clogged fuel filter, etc., to do routine maintenance in good maintenance habits, discharge water tank deposition of impurities and water separator water deposition. 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, with the input current into the armature windings in synchronous generators for power supply unit and the armature magnetic interference. So that the generator output voltage waveform distortion, also appeared higher harmonic components. Such a voltage supply UPS Mitsubishi generator repair, if one of the higher harmonic component is sufficient to disrupt the UPS tracks the input operating voltage PLL circuit, 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, a powerful magnetic field to synchronize the generator armature disturbed harmonic current of relatively small, and thus the output voltage of the high harmonic component decreased to UPS resolve mating, is one 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.
