1. Place the generator on a flat surface and start the engine for a few minutes to increase the oil temperature, then stop the engine.
2. Remove the oil fill bolt (i.e. oil dipstick).
3. Place a pan of oil under the engine, remove the oil drain screw and the oil can be drained from the crankshaft oil reservoir.
4. Check the oil drain screw, seal ring and rubber ring. If there is any damage, please replace it immediately.
5. Reinstall the oil drain screw and tighten it.
6. Lower the engine oil and add it to the upper position of the oil dipstick grid.
The functions of diesel generator oil:
1. Lubrication: There is rapid relative sliding between the piston and cylinder, and between the main shaft and the bearing. to prevent the parts from moving too quickly. Wear requires mise in place of a film of oil between the two sliding surfaces. An oil film of sufficient thickness separates the surfaces of relatively sliding parts, thereby reducing wear.
2. Auxiliary Cooling: Since the specific calorific value of engine oil is low and it is inside the engine, it does not have a cooling effect on its own. However, thermal energy is generated by the combustion of fuel in the engine. When the engine is running, the engine oil can carry heat back to the oil tank and then dissipate it into the air to help the water tank cool the engine. The cooling effect is water (or antifreeze) on the outside of the engine crankcase.
3. Cleaning: Good engine oil can carry carbides, sludge and wear metal particles on engine parts back to the oil tank through circulation. Through the flow of lubricating oil, it can eleliminate the generated dirt. the work surface of the parts.
4. Sealing and leak prevention: Engine oil can form a sealing ring between the piston ring and the piston, thereby reducing gas leakage and preventing external pollutants from entering.
5. Anti-rust and anti-corrosion: Lubricating oil can be absorbed on the surface of parts to prevent water, air, acidic substances and harmful gases from contacting the parts.
6. Shock absorption and damping: When the pressure at the engine cylinder mouth increases sharply, the load on the piston, piston shavings, connecting rod and crankshaft bearing is suddenly increased. This load is transmitted and lubricated by the bearing. , which causes the impact load to act as a buffer.
7. Anti-wear: Adding lubricant to the friction surface can reduce the friction coefficient, thereby reducing friction resistancetement, saving energy consumption and reducing wear: The lubricant can reduce the abrasive wear between the friction surfaces. Wear loss caused by surface fatigue, adhesive wear, etc.
The temperature of the cooling water is relatively high
(1) It is usually caused by the accumulation of dust on the radiator apart from the cooling water. reservoir. In case of heavy dust, debris on the outer surface of the radiator or during operation of the device will be sucked into the water tank by the cooling fan, causing blockage, blocking ventilation and resulting in poor heat dissipation. heat. At this point, you just need to clean the radiator outside the water tank and clean the debris from the device to resolve the problem.
(2) After being used for a long time, the cooling fan connection beltThe generator will gradually age and become easily broken or inelastic, resulting in abnormal blowing capacity. At this point it is necessary to replace the damaged belt. When replacing, all belts must be replaced. Replace them all together instead of just one.
(3) The coolant content is very low. It is necessary to check the factors causing the lack of cooling water. Check the tightness of the cooling water tank and each cooling water pipe. In the event of a leak, it must be repaired immediately. Then add enough coolant.
(4) The use of a coolant that does not meet the requirements causes the accumulation of scale, rust and other substances in the cooling water pipes, resulting in impedes the circulation of cooling water and causes an increaseation of water temperature. Coolant is usually water and antifreeze or water and anti-rust fluid. The pH value of water should be between 6.0 and 8.02_, and pure water is generally used. For cooling systems that have been seriously deposited and clogged, it is best to add 0.5L of detergent for every 7L of cooling system volume, mix it with clean water, start the machine and run it for 90 rain, circulate cooling water to clean. then use clean water to circulate it Xian to prevent the cleaning agent remaining in the pipe from causing pipe corrosion.
