There are many reasons for the failure of industrial diesel generators. One can expect and must be prepared for the inevitable in an industrial setting.
Below are the most common maintenance problems and possible solutions for industrial diesel generators.
Coolant level drop alarm/stop.
External leakage or internal leakage is the main reason for the low coolant level. Although many industrial diesel generators are equipped with such alarms, few have dedicated alarms to prevent coolant starvation. Generally, this alarm is related to a shutdown due to high coolant temperature. When a generator is installed with an “Approaching Cooling Medium Temperature Alarm” or “Cooling Medium Temperature Warning”, you can identify the fault that caused the shutdown.
Cylinder heater
The cylinder heater actually heats the coolant circulating around the engine block. Maintaining the cylinder temperature prevents the oil from being too rich at low temperatures.
A common misconception is that engines do not need heating in warm climates. Cylinder heaters don’t just help the engine start in cold weather. Depending on the metal from which the engine is made, accelerated wear may occur when starting. Generally, pistons made of aluminum expand faster than iron cylinder liners. Rapid expansion of these pistons can cause wear of the piston skirt.
Cylinder heaters mitigate these wear by maintaining the temperature of the cooling system and maintaining the expansion of the cylinder liner.
Coolant temperature alarm.
The refrigerant low temperature alarm is mainly caused by the failure of the heating module. Use these heaters 24 hours a day, 7 days a week, and they often fail. However, the integral heater never stops the engine. The extreme temperature inside the furnace is what causes the coolant to circulate through the system. Sometimes you can hear the coolant boiling in the block heater.
Oil spill – oil, fuel or coolant.
Routine maintenance is available to prevent leaks. In most cases, oil spills are not real spills, but the result of “wet accumulation”. Accumulation of accumulated carbon particles, unburned fuel, lubricants, condensate and acids in the exhaust system.
The most common coolant leak is inside the cylinder heater tube. The extreme temperatures generated by the bulk heater can cause accelerated fatigue of the heater hose.
In fuel leak repairs, the most common failure is due to excess oil in the tank. This situation is generally due to human factors or pump system failure. To avoid this from happening, it is recommended that you ask a professional to refuel your industrial diesel generator.
