Environmental air temperature, Tr=298K (t=25 C);
Relative humidity, =30%.
2) the crew should be able to work reliably under the following conditions:
The altitude is not more than 2500 meters.
The ambient temperature is 0--40 C.
The relative humidity of the air is not more than 90%.
3) when the operating conditions of the field are different from the above standard reference conditions, the power of the generator set should be corrected.
Two. Summary of Cummings diesel generator set:
Cummins diesel generating set uses the Sino American Joint Cummins series engine (Dongfeng Cummins production B, C and L series diesel engines, Chongqing Cummins production M, N, K, QSK Series) and the domestic and foreign famous brand generators to form the largest joint venture brand in China. Its generator has many advantages, such as high reliability, good durability, good fuel economy, small volume, large power, big torque, large torque reserve and strong versatility. Especially the Chongqing Cummins diesel engine is developed and designed according to the advanced heavy engine technology concept. The product technology, manufacturing technology and application technology of the engine are developed synchronously with the American Cummins company. According to the characteristics of the Chinese market, the engine is developed to produce power, economy, reliability, durability, safety and environmental protection. Leading products.
Three, introduction to Cummings stock company:
Cummins is the largest company in the world today that designs, produces and sells diesel and compressed natural gas engines. As the largest foreign investor in China's engine industry, Cummings has a number of joint ventures and sole proprietorship enterprises in China, including Dongfeng Cummings, Chongqing Cummings and Cummings power generation (China) Co., Ltd., in which Dongfeng Cummings produces B, C and L series diesel engines, with an engine displacement of 3. 9L, 4.5L, 5.9L, 6.7L, 8.3L, 8.9L, 13L, the power coverage is 125-545HP. Chongqing Cummins produces M, N, K and QSK series diesel engine power coverage range from 145 to 1343KW, with an annual capacity of 15000 units. The products are suitable for heavy vehicles, large buses, engineering machinery, mining machinery, petroleum machinery, rail machinery, port machinery, fixed and mobile diesel generating set power stations, ship propulsion power sets and auxiliary power sets, pump power units and other power units.
Four. Advantage of Cummings engine / generator set:
1, basic design features of Cummings diesel generator set
Cummins diesel generator cylinder block design durable, small vibration, small noise; straight six cylinder four stroke, smooth operation, high efficiency; replace the wet cylinder sleeve, long life, convenient maintenance; two cylinder cover, each cylinder 4 valves, full intake, forced water cooling, thermal radiation, performance excellence.
2, Cummings diesel generating set fuel system
The PT fuel system patented by Cummins has a unique overspeed protection device, low pressure pipeline, low pipeline, low failure rate, high reliability, high pressure jet and full combustion. Equipped with fuel oil supply and oil return check valve, it is safe and reliable.
3. Intake system of Cummings diesel generator set
Cummins diesel generator is equipped with dry air filter and air resistance indicator, using exhaust gas turbocharger, fully intake and performance guaranteed.
4. Exhaust system of Cummings diesel generator set
The use of the pulse dry exhaust pipe in Cummins diesel generator set can make use of the exhaust energy effectively and fully exert the performance of the engine. The unit is equipped with a 127mm exhaust pipe and an exhaust bellows, which is easy to connect.
5, the cooling system of Cummings diesel generator set
In the engine of Cummins diesel generator set, the gear centrifugal water pump is used for forced water cooling, the large flow channel is designed, the cooling effect is good, and the heat radiation and noise can be effectively reduced. The unique swirling water filter can prevent rust and corrosion, control acidity and remove impurities.
6. The lubrication system of Cummings diesel generator set
The variable flow engine oil pump, with the main oil channel signal tube, can adjust the pump oil quantity according to the main oil pressure of the main oil channel, optimize the oil volume into the engine and low oil pressure (241-345kPa). The above measures can effectively reduce the loss of pump oil power, improve the power performance and improve the engine's economic performance.
