What are the reasons for the increase in the failure rate of diesel generators?

    Diesel generator sets need to run smoothly and efficiently to power essential equipment in industrial environments. However, some common problems that occur in industrial diesel generators should be paid attention to when used, to prevent the failure of the unit from causing normal operation.

1. Maintenance
    The most common problem is maintenance. Think of the engine on a diesel generator as the engine in a car. Proper maintenance is the key to efficient operation. Manufacturer-recommended maintenance schedules typically include pre-start, semi-annual, and annual diesel generator maintenance. The parts that require regular maintenance include:

cooling system
Fuel System
intake and exhaust
Lubricating oil system
start the system
Engine Monitors, Safety Controls and Control Panels
automatic transfer switch
Oil and Fuel Filter Change
Maintenance of water oil separator

2. Improper power and load

    The most common is improper generator selection. Businesses often want to purchase larger diesel generators than are required for their application as a way to meet their future needs. But running generators under light loads can cause unnecessary damage and waste. When the diesel generator is running, at least 35% of the load must be used.
    Another problem caused by light loads is fuel leaks. The operating temperature of the engine is not high enough for the expansion joints in the exhaust system to seal properly. Too light loads cause diesel fuel to not burn completely and build up in the engine block. This can lead to fuel leakage and fire.

3.Fuel supply
     Lack of fuel can stop the generator and also draw air into the fuel system. Also, running the generator on a non-scheduled basis can cause air to build up in the fuel system, which can shut down the diesel generator.Businesses that do not implement a regular maintenance program and lack regular use tend to accumulate fuel in their tanks. Stagnant fuel causes water to condense, which in turn leads to accelerated microbial growth. This creates contamination and damaging sludge that can damage fuel filters, cause blockages and cause leaks.

    To ensure that the diesel generator can operate normally when needed, the user must pay attention to regular maintenance of the unit and the use of clean diesel that meets the specifications.
