Starlight generator

1.Connecting rod of Cummins generator A.If the copper sleeve of connecting rod is excessively worn,  connecting rod   must be sent to the repair shop with milling machine to replace it with a new copper sleeve (Cummins repair service center). When replacing the new copper sleeve, the piston pin and the new copper sleeve must be brought. The diameter of the copper sleeve of the processed connecting rod is N (50). 825-50. 838mm), K (60.985-61. 024mm). The difference between the diameter of piston pin and copper sleeve is 0. 05mm. B.The connecting rod with connecting rod bush must be scrapped. C.When assembling connecting rod screws, it is necessary to carefully check whether the connecting rod screws are elongated, cracked or damaged. Unqualified connecting rod screws and nuts must be replaced. D.If enlarge connecting rod bush, it is recommended not to exceed two levels at most. E.When installing the connecting rod screw, it is necessary to check whether the connect...

Yuchai YC6TD series diesel engine is a product independently developed by combining the advanced technology of large engines at home and abroad.

We may make some mistakes without fully understanding the operation method of Cummins diesel genset. Today Starlight Power summarizes some incorrect operations. Diesel generator set works at poor diesel oil In this conditions, the oil supply of each friction pair surface will be poor due to poor oil supply, it will result in abnormal wear or burn. Therefore, we should ensure enough diesel oil before start up and during the operation of the unit. After cold start, step on the accelerator sharply If the accelerator is slammed, the speed of the diesel engine will increase sharply, which will cause some friction surfaces on the engine to wear violently due to dry friction. Besides, the acceptance force of piston,   connecting rod   and crankshaft changes greatly, which will cause severe impact and easily damages the parts. Emergency stop the unit with load or suddenly stop after load removal After the diesel generator flameout, the circulation of cooling wa...

The noise reduction of diesel generator sets  needs to deal with the causes of the above noise respectively. The main methods are as follows . 1.  Air intake and exhaust noise reduction: the intake and exhaust air channels in the engine room are used as soundproof walls, and the silencers are set up in the inlet and exhaust air channels. There is a distance buffer in the channel, which can reduce the intensity of the sound source radiation from the engine room. 2.  Control of mechanical noise: the top and surrounding walls of the machine room are covered with high absorption and sound insulation materials, which are mainly used to eliminate indoor reverberation and to reduce the sound energy density and reflection intensity in the machine room. In order to prevent the noise from radiating through the gate, fire-proof iron door is set. 3.  Control smoke noise: the smoke exhaust system installed on the basis of the original primary silencer special two...

Volvo Penta launched the first engine D16 for generator set that meets EU Stage V emission requirements at the Middle East Power Show in Dubai from March 5 to 7. "D16 is just the tip of the iceberg," said Kristian Vekas, product manager of Volvo Penta. "We are currently developing a five-stage engine for each power segment of mobile generator sets, as well as a variety of other new products. Each model can be optimized to meet the unique product and operational needs of the customer and is committed to adding value to its generator set business. ” The D16 is a premium two-speed engine that switches between 1,500 rpm (50 Hz) and 1,800 rpm (60 Hz), providing 570kW and 596kW respectively. It meets the requirements of CARB / EPA Tier 4 Final and EU Stage V for engines above 560kW, with the same hardware and software, and complies with EU RoHS2 standards. With two-speed and combined certificate functions, generating set OEM customers can more e...
