Today, I would like to share with you the precautions on the use of diesel generators. The details are as follows.
Precautions for using diesel generators
1. Diesel engine run-in
A new or overhauled diesel engine must be run in for 60 hours before it can be used at full load. In order to improve the working condition of diesel engine guaranteed moving parts, improve the reliability and service life of diesel engine.
Run-in should be considered according to the use of diesel engine and the way of towing the specific run-in scheme. In principle, the speed and load of the diesel engine should be gradually increased with the increase of the run-in time. During the whole run-in period, the load should be 50%-80% of the 12h calibrated power, and the speed should not be greater than 80% of the calibrated speed. But at the beginning of the run-in, the running time should not be too long under the condition of empty operation or too small load.
Whenever the cylinder liner, piston, piston ring, connecting rod bearing and crank are replaced, short-term running-in is also carried out according to the above running-in conditions.
2. Normal use of diesel oil
After the diesel engine is put into normal use, we should always watch the indicator value of all instruments and observe the dynamic operation of the whole machine; It is necessary to check the liquid level of the cooling system and all parts of the lubricating oil regularly. If it is found that there is no compliance with the requirements or loss and leakage, it should be supplemented or the cause of inspection should be excluded.
During the operation of the diesel generator set, especially when the load is suddenly reduced, attention should be paid to prevent the speed of the diesel engine from suddenly rising (commonly known as the flying car) due to the failure of the governor from exceeding the specified value. When such a situation occurs, emergency measures should be taken quickly, and then the cause can be found out.
3. Diesel engine power matching with working machinery
When choosing diesel engine, users should not only consider the power required by the working machinery, but also consider the load rate of the working machinery, such as intermittent use or continuous use. At the same time, we should consider the running economy of the working machinery, that is, the working characteristics of the load and the characteristics of the diesel engine must be reasonably distributed.
Therefore, the correct calibration of the diesel engine power and the reasonable matching of the diesel engine and the working mechanical characteristics are the premise to ensure the reliable, long life and economic operation of the diesel engine, otherwise it may cause the overload operation of the diesel engine and produce unnecessary faults. Or the load power is too small, the diesel engine power can not be fully used, which is not economic and produce channeling oil and other ills.
Jiangsu Meao Power Technology Co., Ltd. is an important manufacturer of diesel generators. The company mainly manufactures and sells diesel generator sets with power of 3-3000kW, mobile power station of 24-600kW, Marine emergency diesel generator set of 24-800kW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, static speaker, mobile lighthouse, container, etc.) diesel generator At the same time, we are engaged in generator set maintenance and after-sale service of generator set accessories.
