How to Ensure The Normal Operation of Diesel Generator Sets?

Diesel generators are composed of various components, and like any other machinery, these generator components can be damaged or fail for many reasons. Unable to maintain the normal operation of the generator and its components well.

Diesel generators are generally repaired by professional personnel at least once a year, and their regular maintenance, inspection, and repair are the key to determining the lifespan of the generator. In other words, to regularly inspect and maintain the key components of the generator, it is necessary to always remember the status of the equipment.

Here are some of the most important diesel generator components that require frequent inspection and maintenance.

1. AC generator

The main function of an AC generator is to convert the mechanical energy generated by the engine into electrical energy, consisting of two main parts: the stator (static part) and the rotor (moving part). The interaction between these basic components in the magnetic field and electric field can generate electricity.

AC generators are generally considered durable. However, its components need to be continuously monitored to avoid depreciation. When certain components of the generator stop working normally or have rust or coking, immediate maintenance should be carried out.

Insulators are a part of the AC generator, so you need to pay special attention. When the generator is running, if the insulation is not sufficient, the heat emitted will damage various components. Although this problem occurs with the aging of the machine, regular insulation maintenance can minimize its destructive effects.

2. Stator

The stator is a fixed component installed in systems such as generators, motors, and alarms. Its main task is to maintain the alignment of the magnetic field. Its function is to convert a rotating magnetic field into an electric current.

The common faults of stator windings often come from discharge slots, switch surges, overheating, lighting, and single-phase and unbalanced voltages.

The power system is a system in which an electrical fault occurs in the power supply of an induction motor, causing single-phase voltage imbalance. Due to the negative sequence and voltage, unbalanced voltage can cause overheating, which can damage the winding and stator. In the case of rotor overheating, stator winding faults are most likely to occur.

3. Rotors

The rotor is a moving component in the electromagnetic system of motors and generators, opposite to the stator. Usually placed inside the iron core of the stator. From its rotation, it can be seen that its dynamic characteristics are the result of relative motion between vibration and magnetic field.

If there is a problem with the AC rotor, frequent start-up resulting in high load capacity and rotor bar breakage usually cause the rotor to transfer current from the rotor. Once such problems occur, they must be repaired immediately to avoid further damage. Therefore, it is necessary to always pay attention to the starting fault of the generator to determine insufficient torque and avoid high load capacity, which may cause irreversible damage to the rotor bars.

Some components of the diesel engine require regular maintenance and repair, as their failure or damage will seriously affect the normal operation of the unit. The frequency converter and stator rotor are important components in the maintenance process of the generator, and they must be repaired and maintained with high precision.

To keep your diesel generator in good condition, you must be able to identify the necessary generator components for regular inspections.
