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. Weifang Huadong Diesel Engine Co., Ltd. is a professional generators, static speakers, marine diesel engine production and sales business. 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, the viscosity than gasoline, not easy to evaporate, while the auto-ignition temperature but lower than gasoline, thus 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, diesel fuel injection pump through the oil pressure up to 10MPa or more, through the injector injected into the cylinder Weifang Huadong service unit, in a very short period of time is mixed with hot air compressed to form a combustible mixture. Because the diesel engine compression ratio (usually 16-22) of Weifang Huadong unit suppliers, 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 be as 0.6-1.2MPa, temperature of 600-700K), much higher than diesel fuel auto-ignition temperature. Shandong Weifang Huadong unit retailers _ EAST (certified) _ EAST unit provided by the Weifang Huadong Engine Co., Ltd. Weifang Huadong Engine Co., Ltd. (www.hdchai.com) is an industry leader in Shandong Weifang, the internal combustion engine, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Weifang Huadong leadership with the staff warmly welcome all inquiries negotiations to create a better future Weifang Huadong.
