200kVA Cummins Diesel Generator

The diesel generator set is a small-scale power generation equipment, which refers to a power supply device that uses diesel as a fuel and uses a diesel engine as a prime mover to drive a synchronous generator to generate electricity. This is a power generation device with quick start-up, convenient operation and maintenance, low investment, and strong adaptability to the environment. Because of its small size, flexibility, lightweight, complete support, easy operation, and maintenance, it is widely used in mines, railways, fieldwork sites, road traffic maintenance, and factories, enterprises, hospitals, etc., as backup power or temporary power.

The modern power generator consists of a diesel engine, a three-phase AC brushless synchronous generator, a control panel, a radiator, a coupling, a fuel tank, a muffler, and a common base. The flywheel housing of the diesel engine is directly connected with the axial direction of the front section of the generator by a shoulder, and the rotation of the generator is directly driven by the flywheel by a cylindrical elastic coupling, and the connection manner is fixed by screws, so that the two The connection to a steel body ensures that the concentricity of the crankshaft of the diesel engine and the rotor of the generator is within a specified range. In order to reduce the vibration of the unit, shock absorbers or rubber shock absorbers are usually installed at the connection between the main components of the diesel engine, generator, radiator, electrical control box, and the common base.
