Diesel electric control system failures may include the following situations:1Fuel System Failure:

Fuel pipeline blockage, fuel nozzle blockage, fuel pressure insufficiency and other reasons lead to insufficient or unstable fuel, affecting the normal operation of the diesel engine. 2.Air System Failure:

Problems such as blocked air filters and leaking air intakes will affect the air**, which in turn will affect the combustion efficiency and power performance of diesel engines. 3.Ignition system failure:

Including the aging of high-voltage lines, ignition coil failure, etc., resulting in a decrease in ignition capacity, which leads to diesel engine start-up difficulties, stall or stall and other problems. 4.Sensor failure:

The sensor is an important part of the diesel electric control system, including the intake core air shortage pressure sensor, intake air temperature sensor, oil temperature sensor, crankshaft position sensor, etc. The failure of these sensors can cause the electronic control system to not correctly sense and control the engine working state, resulting in the failure of the diesel engine. 5.

Maintenance precautions: In the event of a failure of the diesel electric control system, comprehensive maintenance and inspection are required, and the damaged parts are replaced in time to ensure their normal operation. At the same time, the rational use and maintenance of diesel engines, timely cleaning of air filters, regular replacement of fuel filters and other components can reduce the occurrence of failures and prolong the service life of diesel engines.

The reasons for the failure of the diesel electric control system may be as follows:1Damaged sensor or poor connection:

There are many sensors in the diesel electric control system, such as barometric pressure sensors, temperature sensors, oil pressure sensors, etc. If the sensor is damaged or poorly connected, it will affect the monitoring and control of the system, resulting in diesel engine failure. 2.

Control module failure: The control module is the core component of the diesel electric control system, if the control module fails, it will cause the diesel engine to fail to work normally. 3.

Power system failure: Batteries, generators, and wiring are all important components of the diesel electric control system, and if any one of them fails, it will affect the normal operation of the system. 4.

Mechanical failure: Failure of mechanical parts of a diesel engine, such as fuel injectors, high-pressure oil pumps, valves, pistons, etc., can lead to the failure of the electromechanical excitation control system. Workaround:

1.Check the sensor: If the sensor is found to be faulty or poorly connected, it should be replaced or reconnected in time.

2.Replace the control module: If the control module fails, it should be replaced when the hand is wide.

3.Repair the power system: If the power supply system fails, you should first check whether the battery is fully charged, if you find that the battery is normal, it may be a generator or line fault, which needs to be repaired or replaced in time.

4.Repair of mechanical parts: If mechanical parts fail, they should be repaired or replaced in time.

Before replacing parts, a failure analysis should be carried out to find out the cause of the failure to avoid similar problems.

What should I do when the diesel generator controller fails?

After the engine group can not start normally, we can first look at the battery capacity of the unit, if the capacity of the battery is not enough, it will also lead to the failure of starting, so we have to maintain the battery, and the maintenance is divided into charging and replenishing liquid, if these two are done or can not start normally, the battery has been damaged and can not be used normally, then we can only replace the new battery to start. Some of the reasons why can not be started is that the control screen is held high with the shed, in this case, we only need to check the control screen, there will be a fuse in the control screen, if there is a problem with the fuse, then we need to repair the fuse. **The engine group starts for a long time This situation is very easy to appear, the first thing we do is to see if the capacity in the battery is enough, if it is not enough to repair and maintain it in accordance with the above methods, and then we have to see whether the unit is preheated before starting, if the preheating time is too short, there will also be a long start time or difficult to start, at this time we only need to see whether the accessories of the preheating element are in good condition.

There is also a situation that the air enters the fuel system, and a small part of the system will enter the air during use, and this problem will also occur when there is air in the system, we only need to discharge the air out of the system, and manually put the fuel in the system by ourselves, and it can be used normally after getting it out of the oil return pipe.

Hello dear, glad to have your question What to do when the diesel generator controller fails?

1. The failure of the thermostat of the diesel generator set is that the failure of the thermostat is mainly due to the fact that the outlet valve cannot be opened and closed flexibly. If the outlet valve station is opened too early, the warm-up time of the diesel generator will be prolonged. If the outlet valve is opened too late, it will cause the diesel generator to overheat. Therefore, after the diesel generator has been used for a period of time, the thermostat should be removed for technical inspection.

2. After the diesel generator thermostat is damaged, the thermostat should generally be replaced with new parts, and solder can also be used to repair cracks or cracks under special circumstances. The specific method is to repair the damage with solder, then inject alcohol or ethanol with a syringe above the expansion cylinder, then put the thermostat into hot water, wait for the alcohol or ethanol to expand and expel the air, and then use solder to close the pinhole.

In order to prevent the volatilization of alcohol or ethanol, the welding repair should be fast. The thermostat is usually installed at the interface of the cylinder head outlet pipe.

What should I do when the diesel generator controller fails?

What should I do when the diesel generator controller fails? Hello dear, fault phenomenon: the generator set can be started, but the diesel generator set controller shows that the start fails.

Therefore, if the original lease of the obstacle is delayed, the starting success condition is: power generation, and the generator establishment voltage is too slow so that the control module can not detect the generator frequency during the start-up time, resulting in the failure of starting.

Solution: The slag mold of the successful starting condition is modified to: power generation + speed, and the judgment condition of successful starting is increased.

Fault phenomenon: press the manual button, the generator set does not start, and the generator set controller will display the start and safe operation delay. Cause of failure:
