Must-Stop Fault Codes for Diesel Generator Sets: Protect Your Equipment and Avoid Losses Diesel generator sets are critical backup power sources for many businesses. However, certain fault codes indicate severe issues that require immediate shutdown to prevent costly damage. In this article, we highlight the key fault codes, emergency shutdown procedures, and preventive measures to safeguard your generator set.     1. Fault Codes That Require Immediate Shutdown 1. Over Speed (超速) Risk: Engine speed exceeds safe limits, which can damage mechanical components or even cause catastrophic engine failure.Action: Immediately cut off fuel supply and inspect the governor and sensors for faults. 2. Low Oil Pressure (机油压力过低) Risk: Insufficient lubrication can lead to cylinder scoring, bearing wear, or engine seizure.Action: Stop the generator, check oil levels, inspect the oil pump, and ensure filters are not clogged. 3. High Coolant Temperature (水温过高) Risk: Overheating may warp cylinde...

5 Effective Ways to Reduce Diesel Generator Noise     Electricity is essential in modern life — from homes and offices to hospitals and factories, we all depend on reliable power. That’s why diesel generator sets play a critical role, especially during unexpected power outages or natural disasters. However, one major concern with generators is noise. Continuous loud operation not only disturbs nearby residents but can also cause long-term hearing and health issues. Fortunately, there are several effective methods to reduce generator noise. Below, Hosem Power shares five proven solutions to make your generator run more quietly and efficiently. 1. Build a Soundproof Wall Around the Generator One of the most effective ways to reduce generator noise is to construct a sound-insulated wall around it.You can use concrete or cinder blocks to form an enclosure slightly higher than the generator (about one foot taller).Leave at least 15 cm (6 inches) of space between the ge...

When purchasing a diesel generator set, most people focus only on the engine brand. However, the alternator (generator end) is just as important — it directly determines the output performance, stability, and service life of the entire generator set. Full copper alternators and aluminum-wound alternators can differ in price by 30%–50%, but their quality gap is even greater. To help you avoid costly mistakes, here are three key techniques to quickly identify alternator quality. 1. Check the Material: Copper Wire vs. Aluminum Wire The material used in the stator windings is one of the most important indicators of alternator quality. Advantages of Full Copper Alternators Excellent electrical conductivity Lower heat generation Not easily oxidized Longer service life (typically 15–20 years) Higher efficiency and stronger load capability   Disadvantages of Aluminum Alternators Higher electrical resistance Poorer conductivity More prone to oxidation and breakage Higher ...
