Error method of operation of diesel generators in case of low oil pressure operating oil pressure is too low, the lubrication system can not be properly lubricated oil circulation and pressure, all without adequate lubrication oil. Therefore, the machine in motion the process, to observe the oil pressure gauge or oil pressure indicator light situations. If it is found when the oil pressure falls below a predetermined pressure to immediately shut down, troubleshooting and then continue driving. (8) machine speeding, overloading the machine running as excessive speeding, overloading driving, the diesel engine will run under load is too large, the work speed is too high, could easily lead to rude, cylinder, piston, connecting rod and bear the heat load increased mechanical load generator repair factory, prone to pull the cylinder, bush-burning and other failures. Often overloaded, resulting in a long brutal combustion in the cylinder, the cylinder head gasket is easy to damage. (9) Meng throttle before high speed diesel engine flameout if you suddenly stop running, parts of its huge inertia will crank linkage and valve bodies where there is a generator repair damage and shorten life. Meanwhile, Meng throttle is too late into the cylinder due to excessive fuel combustion in the cylinder wall completely shed Cummins generator maintenance, dilute the oil. In addition, also make pistons, valves and combustion of coke increased significantly, causing nozzle clogging and live Fonseca dead. (10) when a sudden increase diesel cooling water temperature is too high if the sudden increase of the cooling water in the case of the diesel engine overheated water, make cylinder head, cylinder, cylinder and other dramatic changes due to cold cracks. Therefore, the diesel engine overheating should dismount the load, slightly higher speed diesel engine will stall until the water temperature dropped in the water radiator cap, loosen and remove water vapor. If necessary, a slow cooling water is injected into the water radiator. After the generator from moisture, drying must be timely treatment, according to the capacity of the motor size and moisture degree, there are two common drying methods: (1) oven (oven) baking method in areas where conditions permit, the motor as a whole (it is best to turn to the stator and open) into the oven (oven) gradually warming baking. 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, intermediate measure insulation resistance of the motor several times, until it reaches a predetermined value and stable. (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 adjusting the excitation current generator for service, the stator short-circuit current of 50% to 70% of the 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 ℃, measured once every 30min insulation resistance and temperature of the coil until the insulation resistance reaches a predetermined value well stabilized. Which is good generator maintenance, the diesel generator (certified), Pingshan generator maintenance provided by the Electrical Equipment Co., Dongguan ShangXi firewood. 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.
