Composition diesel generator set (genset world by engines, generators and control systems are assembled, no one manufacturer only produce engines, generators and control systems and production, while the assembly and manufacture of generator sets, strictly speaking, All generating sets are assembled machine) original machine: domestic habits understood as non-assembly unit in China; assembly machine: domestic habits understood as Chinese territory to import assembled engine unit; domestic machine: the domestic engine and generator assembled unit. Weifang Huadong Engine Co., Ltd., welcomed the new and old customers to buy. In fact, the working process of diesel engines with petrol engine the same, each work cycle has gone through intake, compression, for power, exhaust four stroke. However, since diesel fuel is diesel fuel having a viscosity greater than gasoline, generators offer not readily evaporate, while the auto-ignition temperature but lower than the gas, thereby forming a combustible gas mixture and ignition are different from the gasoline engine. In the intake stroke diesel inhaled pure air. When near the end of the compression stroke generating set manufacturer, diesel fuel injection pump through the oil pressure up to 10MPa or more, through the injector injected into the cylinder, in a very short period of time processors and high-temperature compressed air mixing units, form a combustible mixture. Because the diesel engine compression ratio (usually 16-22), so the compressed air pressure inside the cylinder end up 3.5-4.5MPa, while temperatures up 750-1000K (and gasoline engine hybrid gas pressure at this point will 0.6-1.2MPa , temperature of 600-700K), much higher than diesel fuel auto-ignition temperature. Type diesel generator sets are many, mainly in the following eight classification (1) The fuel classification engine; separable diesel generator sets and composite fuel generator sets (2) In accordance with the speed classification; can be divided into high, medium and low speed diesel generating units (3) in accordance with the conditions of use classification: can be divided into land use, marine, trailer type diesel generators and cars. Where land generating sets: including mobile and fixed. Land use unit can be divided into common type, automation, low noise, low noise automation type four. (4) In accordance with the generator output voltage and frequency classification: it can be divided into AC generators and DC generators. Where AC generators; including the IF frequency 40HZ and 50HZ. For small and medium power frequency 50HZ generating sets table set voltage is typically 400V; calibration voltage large generator is generally 6.3 ~ 10.5kV. Generator set manufacturers _ _ Weifang Huadong turbines generators provided by the Weifang Huadong Engine Co., Ltd. Weifang Huadong Engine Co., Ltd.
