Cummins generator set is the ideal power for diesel generator sets with better performance in China. The cylinder block of Cummins diesel generator set is designed to be sturdy and durable, with low vibration and low noise; four-stroke, stable operation and high efficiency; replacement of wet cylinder liner, long life and easy maintenance ;Two cylinders and one head, 4 valves per cylinder, sufficient intake air, forced water cooling, small heat radiation, and excellent performance. 1. Cummins series brushless three-phase AC synchronous generator adopts advanced and unique forming hard coil winding technology, and adopts VPI vacuum pressure dipping technology to insulate winding stator and rotor, which greatly improves the inter-turn of the generator, phase-to-phase insulation strength, so that the operating reliability of the generator has been fully guaranteed, and further improve the service life of the generator. 2. The overall salient-pole rotor has strong windings, unique core ventilation structure, good cooling effect of windings, full damping windings, and stable parallel operation. 3. Cylindrical steel plate base, the whole is firm and reliable, and the shape is novel; 4. The automatic voltage regulation has high precision, and has the characteristics of low-speed protection and reliable differential adjustment during parallel operation, and the overall solid sealing process, three-proof and anti-vibration performance are good; 5. According to different installation requirements, there are two structures of single bearing and double bearing: the single bearing structure adopts the international general SAE standard flywheel interface and connecting piece connection, and can also be customized for non-standard connection; the transmission end cover of the double bearing structure has convex There are three forms of edge cover, integrated cover and ordinary cover.
