Recently, some vessels had trouble with cyl oil feed to cylinder liner. Cyl liner and piston ring, piston much worn down after renewing in short time.
The problem due to poor condition of cyl oil lubricator mechanical type. Ship or technician even try to repair cyl oil lubricator, however, condition was not improved.
Main cause of this is due to the cyl oil lubricator was not calibrated to adjust feed rate evently.
MTB received order from ship owner that need to overhaul and adjust feed rate equaly.
Proceed to disassemble each part of the lubricator for cleaning, inspection and evaluation. The conditions are listed as below:
+ The arms, cam shaft surfaces are not worn.
+ Survey block is transparent and not cracked.
+ The pump pistons are in good condition.
+ Other parts are in normal condition.
Reassembled the lubricator, check and calibrate lubricator uniformity by test bench.
- After reassembling, condition of cyl liner, piston ring in normal after certain working time.
- Case study should be noted: Cyl oil lubricator should be frequently overhaul and calibrated on bench.
