What mistakes should be avoided when starting a diesel generator?

1. When the diesel engine operates with insufficient engine oil

At this time, insufficient oil supply will cause insufficient oil supply to the surfaces of each friction. pair, resulting in abnormal wear or burning. For this reason, it is necessary to ensure a sufficient quantity of engine oil before starting the diesel generator and during operation of the diesel engine, in order to avoid cylinder drafts and tile combustion failures due to lack of oil.

2. Emergency shutdown with load or shutdown immediately after sudden removal of the load

After the diesel engine generator stalls, the circulation of cooling water stops and heat The dissipation capacity decreases sharply. If it decreases, the heated parts lose their cooling, which can easily cause overheating of the cylinder head, cylinder liner,of the cylinder block and other mechanical parts, produce cracks or cause excessive expansion of the piston and blockage in the cylinder. lining. On the other hand, if the diesel generator is stopped without idling to cool, the friction surface will be insufficiently oiled. When restarting the diesel engine, poor lubrication will worsen wear. Therefore, before stalling, the diesel generator must discharge the load, gradually reduce the speed and operate without load for a few minutes.

3. Operating under load without warming up the engine after a cold start

When the diesel generator starts cold, due to the high viscosity and poor fluidity of the engine oil, it is The oil pump does not supply enough oil, and the friction surface of the machine is poorly lubricated due to lack of oil, causing rapid wear and even failures such as arripping of cylinders and burning of tiles. Therefore, after the diesel engine has cooled and started, it should be run at idle speed to warm up, and then run with load when the idle oil temperature reaches more than 40°C, the machine should be started in low gear and ride while; a certain mileage in each gear sequentially until the oil temperature is normal and the oil supply is sufficient. After that you can move on to normal driving.

4. Accelerate the diesel engine hard after a cold start

If the accelerator is pressed hard, the speed of the diesel generator will increase sharply, causing some friction on the machine. The surface is heavily worn due to dry friction. Additionally, when the throttle is struck, the force received by the piston, connecting rod and crankshaft changes significantly, causingviolent impact and easily damaging parts.

5. Operation when the cooling water volume is insufficient or the cooling water and engine oil temperatures are too high

Insufficient generator cooling water volume diesel will reduce its cooling effect. , the diesel engine overheats because it cannot be cooled effectively; If the temperature of the cooling water and engine oil is too high, it will also cause the diesel engine to overheat. At present, the cylinder head, cylinder liner, piston components and valves of the diesel generator are mainly subjected to large thermal loads, and their mechanical properties such as strength and toughness decrease sharply, increasing the deformation of the parts, reduces the assembly clearance between parts and accelerates the wear of the parts, in severe cases, crackss and parts of the machine can get stuck. Overheating of the diesel generator will also aggravate the combustion process of the diesel engine, causing the injector to operate abnormally, causing poor atomization and increased carbon deposits.

Can the cooling water valve be closed if the air temperature at the generator inlet is low?

The first thing after the interruption is to check on the spot if it is true. In other words, it's possible that the interrupt signal you received came from monitoring. Second, it is an on-site inspection. If this is true, the cooling water is indeed true. In the event of an interruption, the cause must be found immediately. At this point there is no need to shut it down immediately, as the unit can usually run for a while without cooling water. Of course, if you check the cause but don't find ituve and the operating temperature of the unit has exceeded the standard, stop the machine in time. The second is that if the on-site inspection of the unit cooling water is normal, check the monitoring equipment to see if there is an equipment problem.

Yes. There are large and small cycles in the diesel generator cooling system. When the water temperature inside the diesel generator body is lower than 70°C, the water outlet valve of the thermostat is closed and all the cooling water returns to the water. pump through thermostat bypass valve Imported for recycling. A generator is a mechanical device that converts other forms of energy into electrical energy.
