First, the basic equipment of diesel generator sets, including what system? A: The diesel generator set includes six systems, namely: (1) the oil lubrication system; (2) fuel system; (3) control and protection systems; (4) cooling cooling system; (5) the exhaust system; (6 ) starting system. Second, the apparent relationship between diesel generator set power, active power, rated power, maximum power, economic power between? A:. (. UPS is the English abbreviation Uninterruptiable Power Supply, translated into an uninterruptible power supply) a unit of apparent power KVA, our habits for transformers and UPS express its basic function is: when the mains power supply interruption recovery generator , uninterrupted 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, 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. Cummins diesel engine Description: 1, the basic design features: cylinder rugged design, small vibration, low noise; inline 6-cylinder, four-stroke, smooth operation, high efficiency; replace wet cylinder liners, long life, easy maintenance; a two-cylinder cover , 4 valves per cylinder, intake adequate performance; forced water cooling, thermal radiation is small. 2, the fuel system: Cummins PT fuel system patented, has a unique overspeed protection devices; low-pressure pipelines, pipe a small, low failure rate and high reliability; high-pressure injection, combustion. Equipped with fuel oil and oil return check valve generator recycling companies, the use of safe and reliable. 3, the intake system: air-dry type air filter and air resistance indicators, using HOLSET exhaust turbocharger, intake adequate performance is guaranteed. 4. Exhaust system: using pulse dry exhaust pipe, which can effectively utilize the exhaust energy, full engine performance; equipped for 127mm diameter exhaust elbow and exhaust bellows, easy to connect. 5, lubrication system: 60GAL variable flow oil pump, with the main oil pipe channel signal, according to the main oil pump fuel oil pressure to adjust and optimize the amount of oil into the engine; low oil pressure (241-345kPa), these measures will reduce pumping power loss, increase power, improve the economy of the engine. 6, cooling system: engine using centrifugal pump forced water cooling gear generator recycling telephone, high flow waterway design, good cooling effect, which can effectively reduce the thermal radiation and noise. Spin-mounted water filter, to prevent rust and corrosion where the generator recycling, control the acidity and remove impurities; 7, power output: Before you can install the crankshaft pulley damper dual-slot power output, the engine is equipped with multi-slot of the front accessory drive pulleys, can bring a variety of front-end power output device. Flywheel and flywheel housing: SAE14 "SAE1 # flywheel housing flywheel engine mount: front and rear engine bracket generator equipped with a total of three phone recycling, recycling generators Xie Gang, Dongguan, Dongguan ShangXi firewood on firewood provided by the Electrical and Mechanical and Electrical Equipment Co., Dongguan ShangXi firewood. Equipment Co., Ltd. (www.dongguanfadianji.cn) strong, credible, diesel generator sets and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers.
