Diesel generator set has a more powerful vibration which situation? How to deal with shock powerful diesel generators? Failure to check: diesel engine itself a multifaceted examination (including the governor decomposition inspection, replacement uniform torsion plate, etc.), failed to find the real cause of vibration and tour cars. Finally, we analyze the view that the diesel engine itself is not the problem, but the diesel engine crankshaft - coupling - traction generator rotor rotary body constituted by an abnormally unbalanced torsional vibration and rotation Daewoo generator maintenance, their combined effect caused the unit vibration and speed fluctuations. According to this line of thought, it was discovered elastic coupling surface temperature is significantly lower than the locomotive engine oil temperature, and further found that there is a big air travel between the spline shaft couplings, lag torsion angle up to 10 °, it is determined that the elastic coupling Part reed fracture problem. Disintegration of inspection, found that 12 groups in five main spring break generator set maintenance company, which is the crux of the issue. Generators and machines and the advantages of a cabinet and improve power system reliability and continuity; because more generators in parallel to a power grid, power supply voltage and frequency stability, can withstand greater impact load changes. 2, more economical. According to the size of the load line, put the appropriate number of units of small power generators to reduce the fuel load to run small power unit to bring waste oil. 3, maintenance, easier to maintain multiple diesel generators in parallel, can be centralized scheduling, allocation active load and reactive load, make maintenance easy and timely maintenance. 4, more flexible for future expansion; now only need to install the necessary equipment power of generators in parallel, until later when you need to expand network capacity, additional generators, and can easily scale unit and the machine, so that the initial investment is more economy. Power generator maintenance, generator maintenance clouds, on firewood provided by the Electrical and Mechanical and Electrical Equipment Co., Dongguan ShangXi firewood. Electrical Equipment Co., Ltd., Dongguan ShangXi Chai (www.dongguanfadianji.cn) strong, credible, diesel generator sets and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the diesel generator and you hand into the brilliant, for a better future!
