1. Daily maintenance:
1. Check the daily working report of diesel generator set.
2. Check the diesel generator daily for damage, leaks, and loose or worn belt.
3. Check the diesel generator: oil level and coolant level.
2. Weekly maintenance:
1. Repeat the daily inspection of the diesel generator set.
2. Drain any water or sediment from the fuel tank and fuel filter.
3. Check the air filter, clean or replace the air filter element.
4. Check the water filter.
5. Check the starting battery.
6. Start the diesel generator and check if there is any impact.
7. Use an air gun and clean water to clean the heat sinks on the front and rear ends of the cooler.
What are the avadvantages and disadvantages of water-cooled and air-cooled diesel generator sets?
1) The temperature is low, the combustion conditions of diesel in the cylinder deteriorate, the fuel atomization is poor, and the Combustion occurs after ignition. Over time, the engine tends to run erratically, worsening damage to crankshaft bearings, piston rings and other components, reducing power and economy.
2) Water vapor after combustion easily condenses on the cylinder wall, causing metal corrosion.
3) Diesel combustion can dilute engine oil and worsen lubrication conditions.
4) The fuel is not completely burned and forms a colloid, causing the piston ring to become stuck in the piston ring groove, the valve to become stuck, and the pressure in the piston to decrease. cylinder at the end of compression.
5) The water temperature is too low and the engine oil temperature is too low. Engine oil becomes thicker and fluidity becomes poor. The amount of oil pumped by the oil pump is low, resulting in insufficient oil. power supply to the generator. In addition, the crankshaft bearing clearance becomes smaller and lubrication is reduced. Many operators do not want diesel generators to operate at operating speeds. They believe that lower speeds will not cause a breakdown. In fact, too low a speed will also cause bad consequences, as follows:
1) Too low a speed will reduce the power output of the diesel engine and reduce its power;
2 ) Too low rotation speed will cause the working speed of each component to decrease, which will deteriorate the working performance of the components, reduce the outlet pressure ofoil pump, etc. ;
3) Reduce the reserve power of the diesel engine, which must be in normal operation. The diesel engine is under full load or overload.
4) If the speed is too low, the speed of the engine working machines; the linkage mechanism will also be reduced, which will reduce the mechanical performance of the work, such as reducing the water flow of the water pump, reducing the water pump. The elevator, etc.
There are only two speeds of normal generators: one is 1500 rpm and the other is 1800 rpm. It is wrong to artificially adjust the generator speed down or up.

The advantages and disadvantages of water-cooled and by air are mainly reflected in the main engine.
The water-cooled diesel engine has an open cycleert and closed cycle, with good cooling effect and low noise.Small and widely used. However, the structure is complex, the manufacturing cost is high, it is relatively bulky, it is easy to corrode, it produces scale, blockages, leaks, it loses a lot of heat, it consumes more oil and it is more difficult to maintain.
The air-cooled diesel engine has simple structure, low manufacturing cost, small size, light weight, low heat loss, relatively fuel efficient, no water leakage, from frost, scale and other defects, short hot-running time and environmental adaptability Good performance and easy maintenance. The disadvantages are loud noise, uneven cooling, high thermal load and high fan power consumption.
