Problems and solutions in daily operation of diesel generators

With the current rapid development of social economy, the demand for electricity in various fields in our country is increasing day by day.Diesel generatorsAs a device with independent power supply characteristics, it can quickly provide AC power to meet the needs of the load. It is put into use in large quantities in the production and operation process of enterprises. However, there are also some problems during its operation, which affects the diesel generator. Usage efficiency, this article will discuss what are these problems? How do they arise? How to solve them?

One, tripping

Trip problems often occur during the operation of diesel generators, which delays the supply of power and affects the normal production of the enterprise. In the case of multiple continuous starts, the battery of the generator will be damaged, reducing the service life of the generator, which will bring great consequences. loss. Since the diesel generator operates under high current and low voltage conditions, do not start it immediately after a tripping problem occurs. Make sure that the interval between the next start and the previous start is more than 5 seconds. If it still If the problem cannot be solved, the interval between restarts must be lengthened, which should be more than 15 seconds. This can ensure the safe operation of the generator equipment and extend its service life.

2. Startup failed

There are also startup failures when using diesel generators. This situation is also very common during the use of diesel generators. There are many reasons for equipment startup failures. In the use of diesel generators, the reasons for startup failures are: It includes many aspects such as power supply, fuel, voltage and operation. Before running the equipment, ensure the power supply first, check the power switch to prevent the fuse from blowing. When the power supply is guaranteed, check whether the fuel of the diesel generator is sufficient. Ensure that the amount of oil can supply the normal use of the equipment. Insufficient voltage will also cause startup failure. As a large-scale electrical equipment, the normal operating voltage of a diesel generator must reach 22V or above to ensure the normal operation of the equipment. After ensuring that the power supply is normal, the fuel level is sufficient and the voltage reaches above 22V, if the equipment still fails to start, it is necessary to check whether the equipment operator's operating steps are standardized. The correct operating sequence is: first turn on the green light on the machine head Carry out inspection, then adjust the switch to "AUTO", then adjust the control switch to "local" and start the generator. During the operation, if the equipment is not operated according to the correct operating procedures, it will affect the diesel power generation startup and safe operation of the machine.

3. Improper handling of high temperature equipment

Diesel generators will increase the temperature of the equipment during operation, causing safety hazards. When the equipment stops working, the generator equipment must be cooled down. Otherwise, on the one hand, there will be safety hazards, and on the other hand, the amount of diesel will be reduced. The service life of the generator equipment. During use, the diesel generator can neither start working at the beginning nor stop working directly. The combustion temperature of the cylinder of the generator is very high. If it stops working directly, it will cause "cylinder pulling" phenomenon. If it occurs, serious safety accidents will occur. Therefore, before the equipment stops working, the operating speed of 800 rpm-1000 rpm should be maintained with the load removed, and the use should be maintained for 3min-5min. Wait until the equipment Stop the operation of the equipment after the temperature drops, which will extend the service life of the diesel generator.

4. "wet stacking" phenomenon

The "wet stacking" phenomenon is a phenomenon that occurs when a diesel generator runs continuously and uninterruptedly. In this case, the fuel will block the exhaust pipe and injector of the diesel generator, affecting the diesel engine. Use of generators. For the occurrence of this situation, it is important to strengthen close observation of the generator's operating status. Therefore, the operator must start from two aspects: the temperature during operation and the fuel-to-air ratio to eliminate potential safety hazards in the equipment. ,Solve the "wet stacking" phenomenon.

5. Improper use of engine oil in diesel generators

Existing diesel generators use two types: Milflo and Shell. However, during the use of diesel generators, staff often neglect to check the type of engine oil and mistakenly refill the engine oil, causing equipment operation malfunctions. Diesel power generation When the engine runs for a long time, it will consume a large amount of engine oil. The oil replenishment will be very frequent, and the amount of engine oil purchased will also be extremely large. However, due to different manufacturers, there are various types of engine oil, and the production methods and characteristics of the engine oil are also different. There is a big difference, so you must be targeted when using it. If two different types of engine oil are mixed and used together, the engine oil will deteriorate and sediment will occur, making the generator equipment unable to maintain normal operation and affecting its performance. Service life.
