Partly or fully clogged drain pipes may not always be given enough attention.
Below main challenges is related to restricted flow in drains – due to partly or fully clogged pipes.
Increased Fuel consumption - up to 1,5%
Increased Lube oil consumption 5-16%
Increased wear on piston rod and stuffing box parts.
Increased wear and problems with hydraulic components and fine filters - due to contamination of system oil.
Incorrect dosing of cyl. oil - based on misleading readings from cyl. oil drain samples (SDA)
Higher risk of cyl. liner scuffing accidents - too late detection / corrective action.
The partly or fully clogging of the drilled channel in the engine frame has a huge negative impact on engine operation:
Scrape Down Analyzes (SDA) made from oil samples, taken at each cyl. drain are misleading - showing incorrect iron content and other misleading parameters.
This phenomenon occurs when fresh oil, dripping from the cyl. liner, is pressed through an 50cm long “plug” of solid sludge - forced by the scavenge air pressure.
The “sludge plug” works as a kind of filter/buffer. The fresh and representable oil (dripping from the liner) will either absorb or segregate iron and other content - depending of the balance, when passing through the “sludge plug”
The results are incorrect readings - often with elevated iron readings at normal operation.
Incorrect (too low/late) Iron readings during abnormal cylinder condition and initial scuffing condition.
Both situations generate unnecessary operational expenses.
