Broken out into weekly, monthly, and yearly actionable steps, this guide to commercial generator maintenance can help you understand the major components of your machinery. Industrial generators require the same care as other equipment, including a regular preventive maintenance schedule. Some components require the knowledge of experienced technicians, like those at Blanchard Energy. However, this guide to industrial generator maintenance also includes maintenance tasks you can do yourself.
Blanchard Energy has a team of experts to help maintain your generators and ensure reliable energy. We back our energy solutions with exceptional service to support your operations regardless of industry.
Consistent power is critical for many industries, from hospitals and construction sites to data centers and manufacturers. You rely on your generator to kick in when a power outage occurs, giving you a sense of security that work will continue. This great sense of security requires a dedicated maintenance schedule. Without it, the generator you rely on may not be as reliable as you think.
Whether you run your industrial generator as prime power or standby for when power outages occur, you can’t underestimate the importance of generator maintenance. A regular maintenance schedule is important for the following reasons:
With a schedule, you can prioritize which parts of the generator to check at which times. As you begin maintenance, keep a log of work, especially when making repairs or replacements. A maintenance log allows other technicians and engineers to understand what’s happening and helps you see issues that build over time.
An industrial generator maintenance checklist will help you look for any major or minor issues. We will help you maintain each aspect of a generator, from checking battery levels and fluids to running load tests and other assessments.
Because generators have many moving parts to keep your operations running as prime or standby power, you will want to focus on several critical components, including:
Other critical components of an industrial generator to maintain include:
Ensure you’re familiar with all the working parts of a generator so you can correctly identify critical components.
You can perform many parts of a generator maintenance checklist on your own. However, for the more technical inspections like running a full load test, you should rely on the professionals. Your warranty may require trained technicians to complete these inspections. If you’re looking for the right people, you can count on Blanchard Energy.
Whether you have a diesel or gas-powered industrial generator, maintenance cycles are similar. Check your unit’s OEM maintenance manual for specifications.
Each time you use a generator, you want to inspect several things before starting the engine.
With general inspection comes cleanliness and looking for the more obvious issues. Check that there are no loose parts, leaks, corrosion, or damage.
While you should do some items on your checklist regularly, other maintenance tasks are only necessary when components reach their limit. As-needed maintenance includes:
When topping up fluids, wait for the generator to settle and cool if it’s been running so the oil drains back down.
Each week, include these tasks in your schedule.
A key part of owning a generator is running it when you don’t need it to ensure everything runs smoothly. As it’s running, check the exhaust system, looking at the manifold, muffler, and exhaust pipe. Inspect the unit for leaks or overheating, and listen for odd noises and misfiring, smoke, or fluctuations in power. Checking the control panel and warning lights will also give you an idea of how the generator is operating.
Monthly maintenance inspections are more intense than weekly tasks. Each month, you’ll need to inspect the generator and conduct a few additional tests.
When topping up the cooling fluid, ensure it’s the correct concentration. Some generators require a mix of antifreeze and water. The battery is also a significant component you want to examine at least once monthly. Battery failure is common without proper maintenance, so check battery levels and corrosion.
In some maintenance schedules, bi-annual inspections are included with annual checks. Depending on your industrial generator, environment, use and other factors, you can determine when the following inspections are necessary:
If your unit is inside a closure, you will also want to check it. Remove obstacles and debris, ensuring enough airflow to prevent the generator from overheating in this process.
Annual inspections are more detailed and include one of the most critical aspects of maintaining a generator — performing a load test. Here’s what maintenance tasks you should perform annually:
The more you use an industrial generator, the more often you may have to conduct these inspections. Your work environment also plays a role. More frequent inspections are necessary if you operate in more severe weather, like extreme temperatures, dust, or humidity.
Make sure to turn off all power switches when inspecting the transfer switch. Sometimes, you may have to coordinate this with a planned power outage to ensure optimal safety measures. Additionally, alternators are often overlooked during the maintenance process. It’s best not to rely on visual inspections but to feel if it’s overheating from a buildup of dirt around the windings. You will also want to check the unit for moisture. Heat, dirt, and moisture can quickly reduce power output levels.
Finally, conducting a load test once a year will show how the generator runs with a full load, ensuring your operations can rely on its power.
Annual tests and inspections are more challenging than a simple oil check, so the generator is more likely to experience problems if you miss one. This is when you can rely on the professionals.
