When the diesel generator set is running, the most common failure problem is "three leaks", namely water leakage, oil leakage, and air leakage. The three leakage failures will directly affect the technical status of the diesel generator set, causing accelerated wear of the unit's components, difficulty in starting, increased fuel consumption, and reduced power, which will lead to frequent unit failures. Therefore, users should pay attention to it and conduct timely inspections and eliminations when encountering the "three leakage" problems.

After many years of maintenance experience, Heyuan Zhongdian has concluded that when users strictly abide by the five-word punctuality of "strict, clean, wipe, grind, and tighten", they can effectively avoid the three-leakage problem of diesel generator sets. These five-word rules are very comprehensive and can prevent failures during the daily use of generator sets. Proper use can reduce the failure rate and improve the efficiency or service life of diesel generator sets. The details are as follows:
