Generator Maintenance
Don't neglect your generator
Generators can often be called on at short notice, so it is essential that they remain fully operational. Singapore-based Maintech Engineering Services highlights six signs that warn a generator may need a repair or maintenance to ensure it is ready when needed.
Regular maintenance is key to ensuring that electric generators run smoothly and remain operational whenever a power outage occurs. In addition, generator maintenance also prevents fuel issues, saves money for the long-term, lengthens equipment lifespan and boosts a generator’s efficiency.
So, it is paramount to keep generators in good working condition – for streamlining operations in the workplace and improving the bottom line.
To do this it is important to conduct frequent inspections to spot any warning signs that show if a generator needs servicing. Let’s look at the six signs you should look out for that may indicate the need to conduct an electric generator repair.
FLUID LEAKAGE
Fluid leakage is one of the easiest signs to spot. If you notice any fluid leaking during routine inspection, schedule an engineer to take a look as soon as possible.
Fuel leakage can lead to increased fuel consumption which results in a higher fuel cost. If it is a coolant leak, there may be a risk of the generator overheating after prolonged operation.
INCREASED FUEL CONSUMPTION
If you notice that your generator is not performing up to the recommended level provided by the manufacturer, it may be due to an increase in fuel consumption.
However, keep in mind that fuel leakage may not be the only cause of high fuel usage. Therefore, you may wish to have an expert access the situation and check for further issues.
SLOW STARTING
If you notice your generator is slow to start whenever it is powered on, it could be a sign of more severe problems. The slow start could be due to a lack of use, especially if this is the backup generator, and therefore may be a non-issue.
However, if the primary generator is giving you problems, that means it is time to give your engineer a call.
DAMAGED OR FAULTY PARTS
It is crucial to look out for any damaged or faulty components when conducting an inspection. A generator that is situated outdoors is subjected to weather conditions that can damage the machine’s components.
There is also an increased risk of the machine parts being damaged when directly exposed to sunlight for a prolonged period.
Look out for any damaged copper windings that may indicate the need for a generator rewind. In addition, any frayed wires have to be replaced, and the loose nuts and bolts have to be tightened up. If you spot any damaged components, it is advisable to call an expert to take a look before activating the generator.
STRANGE SOUNDS
It can be hard to distinguish unexpected noises from the regular sounds emitting from a generator. Pay attention to specific audio cues, such as metal-on-metal sounds, loud banging noises or a sputtering engine that may indicate problems with your generator.
INCREASED GAS EMISSION
It is normal for a few puffs of smoke to be produced when activating a generator, and they should soon dissipate. However, the generator may have an underlying issue if the smoke does not clear up after a few minutes. If the generator emits excessive smoke or the smoke produced is black, you should turn it off immediately and have your engineer inspect it.
Blow-by gas can be emitted when a generator is active. Blow-by occurs when there is a leakage of the combustion gas between the engine’s piston ring and the cylinder wall into the engine’s crankcase. It is not possible to have a perfect seal between the piston ring and the cylinder wall. As a result, this leakage is bound to occur. However, it is still advisable to measure the blow-by gas emitted from a generator regularly. Increased emission of this gas could be a sign of faulty components that need replacing.
It is advisable to schedule regular inspections on a generator to prevent more significant issues down the line. Your engineer will be able to conduct a generator overhaul and detect any problems that need fixing immediately. Performing regular maintenance gives added security and ensures that you are less likely to encounter a faulty generator.
