Why The Filter Cover of Cummins Diesel Generator Set Broken?

A user found that the locating flange hole on the filter cover of a Cummins diesel generator set was broken while using it. Understanding the possible cause of the fault can help us accurately and quickly identify the problem. Today, the generator set manufacturer will analyze the possible reasons behind the broken filter cover of a Cummins diesel generator set.

If the upper cover of the oil filter has obvious fatigue fracture characteristics, it indicates that the oil filter is subjected to alternating loads. Install vibration probes on the diesel engine and oil filter respectively to measure the vibration status of the oil filter during diesel engine operation. After measurement and comparison, it can be found that the actual vibration acceleration of the oil filter is much greater than the vibration acceleration of the diesel engine, and the acceleration has exceeded the bearing capacity of the oil filter design.

There are two reasons for the rupture of the filter cover of the Cummins diesel generator set:

(1) When the upper end cover of the oil filter was bent, there was a cold work hardening phenomenon in the circular arc area. Due to the significant difference in hardness between the cold worked hardened area and the surrounding area, stress concentration occurs.

(2) The installation position of the oil filter is unreasonable, causing excessive vibration of the filter element and excessive additional stress.

Regarding these two causes of rupture, Dingbo Power Generation Equipment has an improvement suggestion to share with everyone: users can adjust the installation position of the Cummins diesel generator set filter and increase the thickness of the fixed bracket. This measure can reduce its vibration acceleration and effectively avoid the upper cover rupture situation.
