First, the basic equipment of diesel generator sets, including what system? A: The diesel generator set includes six systems generator rental trailers, namely: (1) the oil lubrication system; (2) fuel system; (3) control and protection systems; (4) cooling cooling system; (5) Exhaust system; (6) starting system. Second, the apparent relationship between diesel generator set power, active power, rated power, maximum power, economic power between? A: 1. The unit of apparent power KVA, our habits for transformers and UPS express its basic function is (UPS is the English abbreviation Uninterruptiable Power Supply, translated into an uninterruptible power supply.): When the mains power supply interruption, can not uninterruptible power supply capacity. 2. The active power is 0.8 times the apparent power, the unit is KW, our habits for power generation equipment and electrical equipment. 3. diesel generator set rated power refers to 12 hours of continuous operation power. 4. The maximum power is 1.1 times the rated power, but within 12 hours to allow the use of only one hour. 5. Economic power is 0.75 times the rated power generator rental company, is the diesel generator sets no time limit for long-term operation of the output power. In the power running, the fuel most provinces, the lowest failure rate. Third, the best use of power generating units (economic power) how to calculate? Answer: P best = 3/4 * P rated (ie 0.75 times the rated power) four, three-phase generator power factor is how much? To improve the power factor can be added power compensator it? A: The power factor of 0.8. No, because the charging and discharging of the capacitor can cause small fluctuations in the power supply unit and oscillation. How to set parameters for the protection of diesel diesel generators used in the process will often use diesel generators running sudden severe damage, the installation of diesel generators protection device is necessary. When the generator pipe burst, the lack of oil, the oil pressure protection system will start working immediately stop the diesel engine work: When the engine oil system failure, engine overspeed protection system begins to produce work, immediately pull off the oil filter, the engine shut down; When the oil temperature and water temperature exceeds the limit temperature generator rental, temperature of the system will begin to work, the engine stopped working. The engine failure to occur when both the engine stopped working immediately. And a Chinese record of failure and an audible alarm to alert the mechanic check the cause of the failure, troubleshooting, ensure the normal operation of the unit. The main technical parameters: 30-1600kw diesel generator Altitude: 0-2000m Relative humidity: ≤95% Ambient temperature: -10 ℃ -40 ℃ Power supply voltage: 12V / 24V contact output current: 25A overspeed protection: ≤45Hz-65Hz (adjustable) Low oil pressure: 0.02MP oil temperature: ≤95 ℃ -100 ℃ Cummins generator rental, the diesel generator (certified), manhole generator rental is provided by diesel ShangXi Electrical Equipment Co., Ltd., Dongguan. 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.
