How to prevent the diesel generator from burning the shingle suddenly in use? The main reason for burning bush of diesel generator unit is insufficient lubrication between journal and bush or too small clearance. After burning bush of diesel generator unit, severe scratches and scratches will appear on the surface of journal, which will be oxidized and burned to blue. The burning bush is the most severe mechanical failure of diesel generator unit. The condition causing this kind of problem includes mechanical failure and artificial condition. Today, the following aspects are described in detail to effectively prevent the diesel generator from inadvertently burning tiles during operation.
1. The operation of oil is strict. Select the reasonable type according to the maintenance regulations of power generation unit and check the height of oil surface from time to time. If the oil is not enough, add it in time. The oil quantity is insufficient, the oil quantity of the pump of the oil pump decreases, and even the air will continue to be sucked in. Fill up the oil according to the regulations. If insufficient oil is caused by burning oil or leakage, the problem of burning oil or leakage should also be eliminated.
2. When the air temperature is low, lubricate all friction parts sufficiently before the engine runs at high speed. After starting the diesel engine, the initial idle state runs for two to three minutes, then slowly increases to medium speed (warm up). When the coolant temperature is above 60 degrees Celsius, check the indicator lights on the dashboard for oil pressure, water temperature, etc. When the diesel engine is running without abnormal noise and problems, increase the load slowly to complete the work.
3. Pay attention to observe the oil pressure gauge when the engine is running. If the oil pressure is too low, troubleshooting should be done in time. In order to reduce the friction resistance between relative moving parts in the engine and relieve the wear of parts, oil is continuously transmitted to the friction surface of each moving part to form a lubricating oil film and complete lubrication.
4. Clean or replace oil filter element from time to time to prevent oil containing impurities such as metal chips from entering the main oil passage; New diesel generator set after initial operation 50 hours and after overhaul or overhaul 50 hours. The oil change cycle is usually completed with the oil filter and the fuel filter element. The oil change cycle is usually 250 hours or one month. Operate Class 2 oil. The oil can be replaced only after 400 hours of extended operation, but the oil filter (filter element) must be replaced.
5. In daily work, we should perform three tasks: diligent observation, inspection and maintenance.
