In daily life, Copeland DJ piston will have malfunctions. Today, I will tell you about the failure mode and cause analysis of the piston. We will divide the faults according to the damaged area.
1. Copeland DJ piston head stuck
a. The root cause may be cleanliness during installation, damaged or insufficient air filter, incorrect piston used, or insufficient lubrication due to worn piston rings.
2. The piston head is damaged
a. This means that part of the piston head material has melted from the piston crown area, and the piston head area has cracked or broken.
b. The root cause of such failure is related to overheating, improper use of piston or improper use of piston material, excess or improper use of fuel.
3. Damaged piston groove/damaged piston ring
a. This may be caused by over-tight piston ring and piston clearance, overheating, insufficient lubrication, dust ingress (possibly related to cleanliness). Spilled or excess fuel, or excess carbon residue.
4. Damaged piston skirt
a. This failure may be due to lack of adequate piston-liner clearance, overheating due to insufficient piston cooling, insufficient lubrication, excess or cleanliness issues.
5. Piston pin stuck
a. This failure is less common and the root cause may be insufficient clearance between pin and pin hole, insufficient lubrication or cleanliness issues (dirt or debris between pin and pin hole).
6. or a combination of the above areas is damaged.
a. The root causes are mainly related to cleanliness problems, poor filtration, excessive oiling, overheating, insufficient lubrication, etc.
The above is the failure mode and failure cause analysis of Copeland DJ piston. Hope these contents can help you.
