Maintenance of generators: 1. generator maintenance unit should be kept clean, no oil spills, leaks, leak, leakage phenomenon. Each crew member should be intact, firm wiring, instrumentation is complete, accurate indication, no screws loose. 2. The regional changes in climate and seasonal conditions, should choose the appropriate label fuel and oil. 3. Keep clean oil, fuel and container, according to the instructions require regular cleaning and replacement of oil, fuel, coolant and air filter. Oil-external moving parts regularly additional oil. 4. Start the battery should be in long-term floating state regulators, monthly check float voltage, single battery float voltage is 12.18V, 12.24V or according to the instruction, and the electrolyte level. 5. Avoid prolonged idling, fuel level and oil pump height difference is not too large. 6. After the mains power supply should be able to start properly and within 15 minutes. 7. newly installed or overhauled unit should first try to run, in order to be put into use after the performance tested. Overview of diesel generators mist protection system there are many who still do not know some of the works and the advantages and disadvantages of diesel generator sets, diesel generators do not know how to be more protective mist system is protecting. Here from Dongguan Hong Mechanical and Electrical Equipment Co., Ltd. for everyone to explain some knowledge of diesel generator sets mist protection system. First, the main principle of the protection element mist protection system is where OMD generator maintenance, it can promptly detect whether due to bearing damage caused by overheating or excessive leakage of piston rings and other failures in the crankcase to form Imported oil mist generator maintenance, which monitors the main components of the diesel engine is running - the working conditions of the crankshaft and cylinder is normal. In the diesel engine during operation it continuously withdrawn crankcase oil and gas through the sampling tube system, and sent to a sensitive and accurate concentration measuring apparatus. The concentration measuring apparatus comprises an infrared emitting diode and a photoelectric receiver contralateral diode. Light intensity infrared photodiode feeling generated, and the light intensity signal into an electrical signal to the electronic identification device. If the crankcase gas containing oil mist (so that the concentration measuring device for measuring the opacity of the channel is increased), part of the infrared is absorbed in the measuring tube, the light intensity will be reduced, thereby weakening the electric signal. The higher the concentration, the more attenuated signals, when an electrical signal is reduced to a minimum value (ie, when the mist concentrations exceeding the maximum limit) Cummins generator repair, electronic identification device will issue a "OMD high mist" Alert and downtime, while valve box indicating which part of the high oil mist failures, maintenance personnel for inspection. Second, the advantages and disadvantages of imported generator maintenance, the diesel generator (certified), Longgang 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.
