For generators, everyone is familiar with them, but their working principle is not very clear. We all know that generators are bulky machines when not in use, and they are very useful when needed. Below, let me popularize the relevant knowledge of diesel generators. What are the components that diesel generators need to be replaced or cleaned frequently?

1、 After using the generator set for a period of time, it was found that everything else was normal but the power decreased. What is the main reason for this

1. The air filter is too dirty and the air intake is insufficient. At this time, it is necessary to clean or replace the air filter;

2. The fuel filtration device is too dirty and the fuel injection volume is not enough, it needs to be replaced or cleaned;

3. The ignition time is incorrect and needs to be adjusted.

2、 Where is the problem with a generator set that has stable voltage and frequency but unstable current after being loaded

The problem is that the customer's load is unstable.

3、 What is the main problem with the unstable frequency of a generator set

The main problem lies in the unstable speed of the generator.

4、 What are the crucial points to pay attention to when using diesel generator sets

1. The water in the water tank must be sufficient and maintained within the allowable temperature range for operation;

2. Lubricating oil must be in place, but not excessive, and maintained within the allowable pressure range for operation;

3. The frequency is stable at around 50Hz and the voltage is stable at around 400V;

4. The three-phase current is within the rated range.

5、 What are the components that diesel generator sets need to be replaced or cleaned frequently

Diesel filters, oil filters, air filters. (Some generators also have water filters)

6、 What are the main advantages of brushless generators

1. Exemption from maintenance of charcoal brushes;

2. Anti radio interference;

3. Reduce demagnetization faults.

7、 What is the general insulation level of domestic generators

Domestic B-level machines.

8、 What gasoline engine fuel requires a mixture of gasoline and engine oil

Two stroke gasoline engine.

9、 What are the conditions for using two generator sets in parallel? What device is used to complete the parallel operation?

The condition for parallel operation is that the instantaneous voltage, frequency, and phase of the two diesel generators are the same. Commonly known as "three simultaneities".

Use a dedicated parallel device to complete the parallel operation. It is generally recommended to use fully automatic parallel cabinets. Try not to manually merge machines. The success or failure of manual parallel operation depends on human experience. We cannot apply the concept of manual parallel operation to small power supply systems based on the availability of large power supply systems, as their protection levels are completely different.

10、 What is the power factor of a three-phase generator? Can a power compensator be added to improve the power factor?

The power factor is 0.8. No, because the charging and discharging of capacitors can cause fluctuations in the small power supply and unit oscillation.

11、 Why do we require the customer's unit to perform a tightening work on all electrical contacts after every 200 hours of operation? The diesel generator set is a vibration generator.
