What is maintenance engineering?

Maintenance engineering is planning in advance without a machine's breakdown, fixing it faults, and continuously increasing production.

There are four types of machinery maintenance available in industries these are,

Planned maintenance is the action taken to detect and prevent a problem or breakdown in a machine before it occurs. It includes three major activities, which are,

a). Planning

b). Scheduling

c). Documentation

Preventive maintenance is a type of planned maintenance. When an asset or machine is in working condition, it should be planned and scheduled in advance so that it does not face unexpected breakdowns in the future and preform that activity.

It helps prevent unexpected breakdowns of the machine.
When prevent maintenance is executed at the correct time, the safety of the operators, workers, and the machine can be ensured.
The efficiency of the machines can be improved when preventive maintenance is carried out daily.
If preventive maintenance is not carried out on a machine, there is a high possibility of loss of production and high maintenance cost.

First, take a list of all the machines in the company.
In the machine list taken, you need to confirm which machine needs preventive maintenance.
They will schedule preventive maintenance once every six months or 12 months, depending on the machine's usage and condition.
After planning the preventive maintenance, it should need to be approved.
Finally, according to the preventive maintenance schedule, all the machines will be maintained at that time.

Predictive maintenance is condition-based maintenance, which checks the performance and status of the machine while it is running and identifies and corrects the problem before the machine fails.

Reduce maintenance costs and prevent unexpected machine downtime.
This maintenance can be planned during our free time according to our production schedule.
Now, if a machine breakdown occurs, all the next processes that may depend on that machine will be stopped. Due to this, the company will incur huge losses. So this maintenance is very important to prevent this.
To increase the life of parts, equipment, and machinery.
It is used to increase production by 25%, reduce machine breakdown by 75% and reduce maintenance cost by 25% through predictive maintenance.

This analysis can detect bearing wear, shaft misalignment and imbalance in mechanical-type machines.

Through this analysis, it can be known that if any breakdown happens, it can be used for electrical and mechanical machines, and it is at a more advanced level than vibration analysis.

This analysis can be applied to electrical and mechanical machines. Through this analysis, cooling problems, airflow problems, and electrical motor stress of machines can be detected.

Corrective maintenance is correcting it immediately after a sudden stop while running well and returning it to normal.

It is used to repair any part inside the machine if it is broken.
Used to improve machines or equipment and maintain good efficiency.
It helps to avoid wear and tear in machine parts.
By doing corrective maintenance, the pollution caused by the machine can be reduced to the environment.

Check: If the machine is having problems and stopping, you first need to know what the problem is with that machine.
Causes: After that, we need to understand why the problem is occurring in that machine.
Implement maintenance: Maintenance activity should be implemented after knowing the problem and its causes.
Recheck: After completing the maintenance, the equipment should be turned on, and driven to see if the problems occurs again. If it does not, the machine handed over to the production team.
Record: Problems, causes, and solutions should be recorded in the system. Because the next time the same problem occurs in the same equipment, it can be easily solved by keeping this record.

In condition-based maintenance, a machine's running condition is monitored daily, and if the condition is abnormal during the monitoring maintenance is carried out.
Now, let's see how the maintenance will be done in case of any unusual activity.

a). They will do it when the machine or equipment fails.

b). They do it when the performance of the machine decreases.

Through this condition-based maintenance, problems occurring in the machine are detected at the initial stage.
Since we know about these problems in advance, we can easily arrange the machine's spare parts.
After arranging, planning, scheduling, and meeting with the production department, the machine can be stopped, and the work can be started.
