Utilization of Lubricants and Lubricant Parameters on Ships
The utilization of ointments and oils on ships is a significant job overseen by the principle motor lube oil framework. In this post, we will be dealing on how ships engines are lubricated.
This comprises a siphon that compresses the oil, coursing it through a bunch of channels and a cooler.
It is then circulated to every one of the moving parts of the diesel motor
Grease is important to help conquer the evil of friction;
Oils can be animal (whale oil), vegetable (linseed), or mineral (petrol).
Every one of the three kinds of grease has been utilized for hundreds of years to disseminate heat.
It has been used to decrease grinding and battle mileage between the surfaces of two moving parts.
How Ships Engines Are Lubricated: KINDS OF LUBRICANTS
These days anyway we have a decision of two principle kinds of lube oil;
• Mineral Lubricants –
These are acquired from the processing of raw petroleum.
• Synthetic Oils –
Generally new development including the utilization of polyglycols or esters.
In the accompanying areas, we will inspect the utilization of mineral lube oil and its application to marine diesel motors.
The utilization of inferior quality grease oil can prompt a few issues, and it is additionally important to keep up the first properties of the oil.
The main area gives an outline of mineral lube oil properties.
Properties of Lubricating Oils
This is the main property of any grease; the oil’s capacity to flow at specific or determined temperatures and pressing factors.
The consistency should be determined by taking into consideration the application and working temperature range.
For instance, if the thickness of the oil is excessively extraordinary, it will influence the activity of the moving parts against one another.
This contributes to more noteworthy protection from movement.
On the other hand on the off chance that the viscosity is excessively low, it can flow too unreservedly between the surfaces of the segments, neglecting to grease them up appropriately.
The oil can ignite because of a low blaze point.
This is of specific significance while forestalling crankcase explosions.
If its blaze point is low, it will spark because of the great temperature of a problem area causing a blast.
The blaze point of a marine diesel motor lube oil ought to be above 200°C.
This is particularly significant for the chamber grease, as it’s anything but a neutralizer to the acidic sulfur buildups from the burning of HFO.
these are added to the lube oil to inhibit the formation of deposits on the moving parts; additionally, it assists with keeping the oil clean.
Regularly alluded to as the ‘stickability’ of the oil.
It can cling to the surfaces like white metal.
To keep up the greasing up, oil’s properties, temperature, and pressure should be controlled.
This is the obligation of a watchkeeping engineer.
The solids and water ought to be taken out from the oil through centrifuging, regularly did persistently.
Fundamental Engine Lube Oil System
• The oil is siphoned from the fundamental motor sump, through a bunch of duplex oil channels.
Then through the lube oil cooler and around the principle motor segments under tension, in an accompanying way;
• It is siphoned into the fundamental course, forestalling contact between the steel shaft and the white metal bearings.
• The oil is likewise being provided through swivel jointed pipes inside the motor packaging, to the crossheads.
And then to, cylinder cooling and base end course, the oil pressure being expanded by a sponsor pump.
• During this interaction, the oil additionally diverts the heat because of contact from the different segments.
This heat is then carried from the oil by the seawater going through the principal lube oil cooler.
• The motor chambers have their lube oil framework and siphon as the oil needs to be basic, to battle corrosiveness.
The oil is infused through a bunch of concentric spouts or plumes masterminded around the chamber liner.
This greases up the surfaces between the chamber divider and the cylinder rings; the oil control ring is found further down the cylinder.
It is then separated from the fundamental arrangement of pressure rings scratches off the abundance oil, as opposed to permitting it to be burnt in the ignition.
Temperatures and Pressures to be Checked
We have perceived how significant greasing up oil is to a motor;
• Reducing erosion.
• Preventing harm to moving parts.
• Dissipating overabundance of heat.
Upkeep is additionally significant, oil should be changed routinely, the ideal differential pressure of the channels should be kept up and the channels cleaned as required.
Any particles of white metal, earth, or water in the channels ought to be explored right away.
Most motors currently have an in-line lube-oil centrifuge framework that will separate particles of earth and dampness from the oil, assisting with protecting the oil’s innate properties.
