Huadong Power delivered 5 sets 1100kw diesel generator sets to Sinopec East China Petroleum Engineering Co., Ltd. In February 2021, Huadong Power delivered 5 1100kw diesel generator sets to Sinopec East China Petroleum Engineering Co., Ltd. These generator sets will be used as the main power stations for Sinopec’s oil exploration and extraction projects around the world. This batch of diesel generators is equipped with Cummins KTA50-G8 diesel engines, Stanford S7L1D-J4 generators and Deep Sea DSE7320 control systems. Cummins KTA50-G8 Exceptional power Power range: 1250 – 2000 horsepower, maximum torque: 7865 Newtons Meter. Low fuel consumption and excellent economy Cummins PT fuel system, ultra-high injection pressure, ensures good atomization of the engine and complete combustion. The efficient Holset exhaust turbocharger can ensure more thorough intake, improve engine efficiency, further enhance combustion, and reduce engine specific fuel consumption. The air-cooling technology in the cylinder ensures more thorough intake and better fuel economy. Compact structure and easy maintenance Replaceable wet cylinder liners, good heat dissipation effect, easy replacement. All models have strong interchangeability of components and a high degree of series production, making maintenance convenient. The cylinder block and cylinder head adopt built-in pressure lubrication channels, which are compact in structure and have a low failure rate. Advanced design and reliable performance Cylinder block: Made of high-strength alloy cast iron, with good rigidity, low vibration and low noise. Cylinder head: Four-valve design per cylinder, optimized air/fuel mixture ratio, effectively improving combustion and emissions. Camshaft: Single camshaft design can precisely control valves and injection timing, and the optimized cam profile can reduce impact force, improving reliability and durability. Crankshaft: Integral crankshaft made of high-strength forged steel, with angular and journal induction quenching process to ensure higher fatigue strength. Piston: Using the latest aluminum alloy casting technology, ω-shaped head and barrel-shaped skirt design can compensate for thermal expansion and contraction, ensuring good fit. Professional Configuration, Excellent Quality Lubrication System: All moving parts are subject to forced lubrication; a large-capacity gear pump supplies pressure lubricating oil to lubricate and cool the bearings and cool the piston; an oil cooler, a full-flow filter, and a bypass filter ensure that the oil remains in good condition. Fuel System: Cummins PT fuel system, optimized combustion, powerful power; STC step-by-step timing system ensures better combustion under all working conditions; a low-pressure fuel supply system, equipped with a fuel one-way circuit, is safe and reliable. Cooling System: Gears and centrifugal water pumps are used for forced water cooling; a large-flow water channel design ensures good cooling effect; a screw-type water filter and special DCA additive can effectively control the acidity of the coolant, prevent rust and cavitation, and remove impurities. Intake and Exhaust System: The efficient Holset exhaust turbocharger further improves combustion; pressure-type pulse exhaust pipes can fully utilize the exhaust energy to improve engine efficiency; air-cooled technology ensures better fuel economy and emissions. Stanford S7L1D-J4 Superior Durability We know that the oil and gas industry has extremely high requirements for the operation of power generators. Especially when it comes to stability and durability. Each STAMFORD generator is the result of thousands of hours of product development, repeated verification, long-term durability tests, a globalized supply chain, standardized production processes, and a stable quality system. All these ensure that the products fully meet the design standards. Adapt to the harshest environments The STAMFORD generator of Cummins Generator Technology Co., Ltd. is designed and manufactured to withstand the most severe and extreme operating environments. It can maintain stable operation even in Siberia where the temperature drops as low as -20°C, or in oilfield drilling platforms in Saudi Arabia where the temperature can reach up to +54°C. Whether in dusty desert environments or on offshore drilling platforms, it can provide products of various protection levels, 100% meeting reliability, durability and the most stringent environmental requirements. Product Features The power factor of the drilling and power supply unit is usually within the range of 0.7-0.8, while the standard generator set is 0.8-0.9. The optional integrated filter ensures that the drilling power supply unit can operate normally in harsh environmental conditions. The insulation class is “H class +”, the design team has strengthened the original H class insulation system for the harsh environment and operating conditions of oil and gas fields. All wound components are made of specially developed materials and processed with special dip coating techniques, providing a guarantee for the operation of the generator in harsh environments of oil and gas fields. The specially developed resin-based materials provide high processing strength and mechanical strength for the coils and all rotating components. Temperature rise class B The sturdy steel cylinder design can withstand demanding operating environments and high levels of vibration. DSE7320 Control System It is currently compatible with VFD houses from Honghua, Zhongxing, Gemstone, etc. Compatible with VFD house controllers Woodward 2500, DEIF AGC4 controller. There are differences in the main control modes and usage habits, and the control details are slightly different. The K50 series of the Chengkang adopts an electronic speed controller for the speed regulation system and can be directly controlled by the main control module of the VFD house. The main control house BASLER DECS-100 type AVR board directly supplies excitation to the generator.
