MAINTENANCE LUBRICATION
STRATEGY DEVELOPMENT OF
LUCKY CEMENT LIMITED
Internal advisor: Sir Kashif Noor
Objectives:
To ensure asset maintenance
To ensure equipment’s reliability
To reduce major breakdowns
To enhance economic viability of the organization
To cater for the maintenance standards of the organization
Scope:
It’s a basic necessity of any reputable organization.
It has scope in almost all the industries in the world.
It’s the most beneficial preventative measure for wear and tear and corrosion.
Analysis of the different kinds of machines having their own lubricant requirements. Properties of a good lubricant:
A good lubricant possesses the following characteristics:
High boiling point and low freezing point (in order to stay liquid within a wide range of temperature)
High viscosity index
Thermal stability
Hydraulic stability
Demulsibility
Corrosion prevention.
High resistance to oxidation.
Executed Work
In order to assess the work that we have executed, we need to have a thorough understanding of what is required from us.
The objective is to highlight, in brief; typical equipments and lubricants used.
For our project, we restricted ourselves to the kiln area, having the most number of lubrication points.
A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes.
The rotary furnace (kiln) is the heart of the cement plant and is tilted slightly to ensure flow of material to the exit direction.
Maintenance and Strategy
Lube Survey
What is a Lube Survey?
The following data is mandatory when conducting lube survey
•
Asset/Equipment Number
•
Manufacturer
•
Equipment Description
•
Lube Points
•

Condition monitoring is the process of monitoring a parameter of condition in machinery such that it indicates any developing failure. It is a major component of Predictive Maintenance.
Its use allows maintenance to be scheduled, or other actions to be taken to avoid the failure, before it occurs.
Some condition monitoring techniques are as follows:
Vibrational analysis
Oil analysis
Thermal analysis
Ultrasound analysis
Oil analysis
Oil, your machinery’s lifeblood, can reveal its internal condition.
Oil analysis is a quick, nondestructive way to indicate the performance of a machine by studying its properties.
It’s just like a medical test, where we can know about our diseases based on tests performed on our blood sample.
Oil parameters to observe are:
i.
Its temperature ii. Its pressure iii. Its flow iv. Change in level
v. Darkened oil vi. Water emulsion appearance
Importance of oil analysis
Oil analysis is widely recognised as a useful condition monitoring tool leading to reduced maintenance and production downtime.
A good oil analysis package looks at the following main criteria to provide a unique way of telling you what’s going on inside your equipment.
Oil Condition
Equipment Condition
Contaminants
Engine Operating conditions
Chemical and physical lubricant properties to be analysed
TAN is the Total Acid Number and indicates the acidity in the oil. It’s determined by the amount of alkali neutralising the oil sample.
Oxidation indicates oil degradation. It may be due to high temperatures in presence of oxygen or depletion of antioxidation additives in oil.
TBN is the Total Base Number and indicates the alkalinity in the oil.
Insoluble content indicates the quantity of solid particles in the oil. A high insoluble content can be related to severe level of wear.
Moisture contamination is also measured since it hinders in lubricant operation. Additive content, wear and contaminants
