In the use and maintenance of diesel generators in the process, we will encounter many problems, has many years of practical experience in the technical staff of the problems encountered made the following analysis: filter maintenance: the diesel engine filters including air filter, fuel filter, fuel filter with water separator role of the air filter is to filter dust particles in the air, so that the air entering the engine compression cylinder clean, avoid the turbo Early damage to the intake and exhaust and damage the piston. The role of the fuel filter is the diesel filter out impurities and dust particles to ensure the normal operation of the fuel injectors and fuel pump and extend its life. Effect with water separator fuel filter is to filter impurities and larger fuel dust, diesel oil and water separation and precipitation after removal of diesel fuel in the water, in order to improve the quality of the diesel power generator rental, extend the life behind the fuel filtration. Filtration efficiency fuel filters meet or greater than 90% filtration efficiency fuel filter with water separator is greater than 80%. If the presence of water and impurities diesel, fuel system components due to water or the like within the diesel rust and corrosion damage due to the presence of impurities, visible, water and filtered to remove impurities from the diesel fuel system failures and extend life is very important. Replace the fuel filter is based on a different fuel oil replacement cycle is different, when the replacement filter, the filter is full of clean diesel (Note: Carter EFI engine Cummins engine need not require), in Apply a little oil (15W / 40) on the filter gasket. Diesel generators which are generally important technical indicators Zhangzhen Yi:? User value is diesel generator set can instantly start when needed, and to reveal the excellent load power. For this reason an important technical indicators are concerned; when one diesel generator set with a heavy load or with load changes, its output voltage will therefore change into a new value, this change is defined as the voltage stabilization time period Su. It is the smaller the ability to respond to load changes, the stronger the unit, Su is generally from 0.5 to 3 seconds. Then change into the new value of the output voltage at no load and the setting value (380V or 400V) by dividing the difference between the output voltage setpoint as a percentage of the steady-state voltage regulation δu generator rental company, which represents the unit caused by load changes output voltage adjustment function. δu usually between ± 3 ~ ± 5%. With load changes or when, Su and δu are zero is the ideal state, diesel generator sets minimum sought their values. Second is a diesel generator set under the above conditions, its output voltage and frequency changes with the load condition. Defines the frequency settling time and steady-state frequency regulation St δf two parameters. They are also the smaller the better generator rental, instructions and regulatory capacity of the unit to respond to load changes caused due to the frequency change. St ranges from 2 to 7 seconds Soundproof generator rental, δf between 0.5 to 5%. Third, the effective rate of the diesel engine fuel consumption ge and effective efficiency ηe. The former is defined as the amount of fuel within one hour per kilowatt output effective power, consumed by the internal combustion engine. This is a measure of the fuel consumption of a diesel engine important indicator, ge usually between 220 to 285 grams. The latter is defined as the transformation of one kwh effective heat and power to complete one kwh than the effective work of the heat consumption. value ηe is generally 0.7 to 0.85. It shows the effective efficiency of the diesel engine, the larger the better. Silent generator rental, the diesel generator (certified), the South China Sea generator rental Dongguan ShangXi firewood provided by the Electrical and Mechanical Equipment Co. Electrical Equipment Co., Ltd., Dongguan ShangXi Chai (www.dongguanfadianji.cn) is an industry leader in Dongguan, Guangdong, diesel generator sets, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. On the diesel generator leadership with the staff warmly welcome all inquiries negotiations to create a better future for diesel generators.
