How to Maintain Diesel Generator Sets on Construction Sites Properly?

As critical backup power equipment on construction sites, diesel generators play a vital role in ensuring the stable and reliable operation of all site operations. Regular maintenance and upkeep of diesel generator sets are key to guaranteeing their performance and lifespan. This article will provide a detailed explanation of diesel generator maintenance practices for construction sites from the following aspects.

Basic Maintenance of Diesel Generator Sets

Regular Inspection and Cleaning

Regular visual inspections of diesel generators are essential. Make sure the exterior surface of your generator and the generator room remain clean and tidy. Trailer-mounted mobile generators are commonly used on construction sites. Generally, the regular inspection items of generator include, but are not limited to: checking the tire pressure of the trailer, checking the trailer body connection bolts for looseness, checking if the soundproof enclosure bolts are loose, and confirming that the exhaust, air intake, and ventilation systems are functioning smoothly. Additionally, it is necessary to regularly clean the exhaust and ventilation systems to ensure they remain unobstructed, preventing dust and debris from affecting the equipment's heat dissipation and performance.

Fuel Management

Ensure the diesel fuel tank has an adequate fuel supply, typically enough to meet at least 8-12 hours of operation. Inspect the fuel system for leaks and replace the diesel fuel filters regularly to maintain fuel cleanliness. Using low-quality or contaminated fuel can clog filters and injectors, leading to reduced engine performance and increased maintenance costs. Therefore, it is essential to choose a reputable fuel supplier to ensure fuel quality.

Oil and Oil Filter Replacement

Engine oil, often referred to as the lifeblood of the engine, has many functions such as lubrication, cooling, cleaning, and rust prevention. Over time, engine oil degrades and loses its effectiveness. Thus, it is crucial to replace the engine oil and oil filters regularly. Generally, follow the intervals recommended in the generator set's user manual or by the manufacturer. Additionally, check for oil leaks and ensure the oil filters are in good condition.

Cooling System Maintenance

The cooling system of diesel generator regulates the engine's operating temperature to prevent overheating. Regularly check the coolant levels. Ensure the coolant is sufficient and it has not deteriorated. Clean dust and debris from the radiator surface to maintain its optimal heat dissipation performance. Furthermore, replace the antifreeze periodically to prevent the equipment from freezing and cracking during winter.

Professional Maintenance of Diesel Generators

Lubrication System Maintenance

Proper lubrication is crucial for the smooth operation of the generator engine. Regularly inspect the tension of fan belts and charger belts, and adjust or replace them as necessary. Additionally, check that all bolts on the unit for looseness, especially the external main connection bolts. Inspect the lubrication system to ensure there are no oil leaks. Make sure the oil filters are in good condition.

Air Filter Replacement

Air filters are responsible for filtering the air entering the engine, preventing dust and debris from getting into the cylinders. Over time, the air filters of diesel generator can become clogged, which will reduce air intake efficiency and affect engine performance. Therefore, regularly inspect the air filters and it is recommended to replace them annually or as needed.

Electrical System Inspection

Diesel generator sets rely on batteries to start and control. Regularly check the battery terminals for signs of corrosion and clean them. Ensure the batteries are securely fastened and properly connected. Periodically test the battery voltage and replace the batteries as needed to avoid unexpected failures.

Safety Protection Device Inspection

Diesel generators are often equipped with various safety protection devices, such as overspeed protection and overload protection. Regularly inspect the performance of these devices to ensure they function correctly in emergencies. Additionally, conduct simulated tests of the safety protection devices and perform constant-load operation tests to verify their performance.

In addition to the maintenance tasks mentioned above, regular performance testing of the generator set is also important. When a generator set malfunctions, timely and accurate fault diagnosis is key to resolving the issue. If you encounter generator faults or abnormal situations that cannot be resolved, promptly contact the manufacturer or professional maintenance personnel for assistance.
