After the generator from moisture, drying must be timely treatment, recovery based on the capacity of the generator size and the degree of moisture Cummins motor, there are two common drying methods: (1) oven (oven) baking method in areas where conditions permit will gradually warming the motor overall (it is best to turn to the stator and open) into the oven (oven) and bake. Oven (oven) should be ventilated. In order to take away the moisture inside the motor, and the best sandwich, put the motor in layers, heating in the outer layer. The temperature of the inner layer is kept at 90 a 100 ° C, and can not have fire, smoke, and other flammable and corrosive gases. General requirements for continuous baking 8 ~ 18h, several intermediate measure the insulation resistance of the generator motor recovery, until it reaches a predetermined value and is stabilized. (2) steady state short-circuit current alternator wet method, in the three-phase shorting outlet box, then the generator speed up to provisional rotating speed, remains unchanged, and then adjust the excitation current, short-circuit current of the first stator 50% to 70% of rated current, holding 4 ~ 5h, then increasing the exciting current, short-circuit current of 80% to 100% of the rated value, so that the coil temperature is kept below 85 ℃, 30min measured once every coil insulation and temperature resistance, insulation resistance reaches a predetermined value until the well is stable. Winter is coming, to remind the user of diesel generator sets in the course should pay special attention to the following matters: 1, replace the radiator (tank) in the cooling water, it is recommended to add a sufficient amount of antifreeze to prevent the radiator, cylinder Donglie body; 2, users reclaim power generator in northern cold areas, need to add antifreeze device generators, such as: furnaces, oil heater, heater, water temperature, to prevent not start properly; 3, boot, appropriate to increase the idle running time, to determine the body temperature reaches the relative temperature, and high-speed operation, it is recommended: idle running: 8-10 minutes; 4, oil and diesel fuel used to replace diesel generators recovery, recommended: the relative concentration of oil change lower diesel use pour point below room temperature 5 degrees Celsius (depending on region); 5, such as generators do not add antifreeze, after stopping in after use, put a clean body and radiator cooling water. Where recovery generator, the diesel generator (certified), Wangniudun generator recovered by Chai Electrical Equipment Co., Ltd., Dongguan ShangXi. Electrical Equipment Co., Ltd., Dongguan ShangXi Chai (www.dongguanfadianji.cn) is an industry leader in Dongguan, Guangdong, diesel generator sets, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. On the diesel generator leadership with the staff warmly welcome all inquiries negotiations to create a better future for diesel generators.
