Cylinder Lubrication Systems

To obtain and maintain a good cylinder condition it is of great importance that cylinder lubricators must function properly.

Reference with MAN B&W service letter SL2016-632/AAB, cylinder lubricator system to be overhauled every 5 years or 32,000 R/H to ensure optimal and trouble-free operation. This will ensure trouble-free operation and dosing of the correct lubrication amount based on the provided set point.

Note that lack of maintenance may result in low or missing accumulator pressure, worn solenoid valves as well as defective non-return valves, which all may cause excessive lubrication above the set point. This can be avoided by using the recommended overhaul and maintenance strategy.

It is also very important to make sure correct timing, functioning, and dosing of the mechanical cylinder lubrication systems.
