Further, described cylinder head oil pocket 11 is connected with described oil sump 1 by oil pipe 13, so that described
The liquid that oil gas condensation in cylinder head oil pocket 11 becomes flows back to described oil sump 1 by described oil pipe 13.
Specifically, may there is oil gas in the machine oil sucked due to high-order integrated collecting filter 3, therefore machine oil enters
After entering slave oil storage room 6, a part of oil gas is condensed into liquid through supercooling, and a part of oil gas rises to gas
In cylinder cap oil pocket 11, it is to avoid mixed oil and gas in machine oil, affect lubricant effect.Rise to cylinder head oil pocket
Oil gas in 11, after being lubricated the parts in cylinder head oil pocket 11, then flows after being condensed into low pressure oil again
Return to oil sump 1, to recycle, strengthen machine oil utilization rate.
Specifically, the double pump system that the application provides ensure that timely, stable, continuous print high voltage supply pressure
Power；ICS intercooler system ensure that engine lubrication system thermal balance.Additionally, cellular-type machine oil storage room can
Effectively reduce machine oil air content and assist reduction oil temperature.Therefore, high-speed vessel engine lube system
System performance is greatly improved, and can meet engine speed high, the lube system that vessel speeds is fast, operating mode is complicated
System requirement.
It follows that introduce the operation principle of described electromotor two-pump lubricating system.
