Answer / vinay mishra

Basically there are only three types of maintenance i.e.
1. Preventive maintenance
2. Predictive maintenance
3. Reactive Maintenance

Preventive maintenance - Every parts connected with a machine have a particular life in the terns of running hour, After this life the running of equipment there is big chance to failure of parts / equipment catastrophic risk etc The life of spare parts we find either by manual of machine or the vendor who manufactures the machine .after finding the original life we make a schedule to perfoem the maintenance activity of each parts as per their respective running hour to avoid breakdown .

Predictive maintenance - in this type of maintenance we predict the condtion of equipment as per schedule . Mostly condition measuring tools of equipment are viberation, temp. , Thickness ,flow , noise ,lubrication wear particle analysis .Initially we make a base line for these parameter for correct operation and compare it with as per predictve schedle data found . any sudden change in parameter will alert us to take maintenance of equipment and by this we avoid breakdown .

Reactive maintenance - Some time it is called as Break down Maintenance

1. Breakdown maintenance:

It means that people waits until equipment fails and repair it. Such a thing could be used when the equipment failure does not significantly affect the operation or production or generate any significant loss other than repair cost.

2. Preventive maintenance ( 1951 ):

It is a daily maintenance ( cleaning, inspection, oiling and re-tightening ), design to retain the healthy condition of equipment and prevent failure through the prevention of deterioration, periodic inspection or equipment condition diagnosis, to measure deterioration. It is further divided into periodic maintenance and predictive maintenance. Just like human life is extended by preventive medicine, the equipment service life can be prolonged by doing preventive maintenance.

2a. Periodic maintenance ( Time based maintenance - TBM):

Time based maintenance consists of periodically inspecting, servicing and cleaning equipment and replacing parts to prevent sudden failure and process problems.

2b. Predictive maintenance:

This is a method in which the service life of important part is predicted based on inspection or diagnosis, in order to use the parts to the limit of their service life. Compared to periodic maintenance, predictive maintenance is condition based maintenance. It manages trend values, by measuring and analyzing data about deterioration and employs a surveillance system, designed to monitor conditions through an on-line system.

3. Corrective maintenance ( 1957 ):

It improves equipment and its components so that preventive maintenance can be carried out reliably. Equipment with design weakness must be redesigned to improve reliability or improving maintainability

4. Maintenance prevention ( 1960 ):

It indicates the design of a new equipment. Weakness of current machines are sufficiently studied ( on site information leading to failure prevention, easier maintenance and prevents of defects, safety and ease of manufacturing ) and are incorporated before commissioning a new equipment.

In Rankine cycle there is a concept of Tm(mean temp of heat addition)For calculating the efficiency of the cycle we generally use n=1-T2/T1 again Tm taking into consideration we get n=1-T2/Tm as T1>Tm so he efficiency will be different for same cycle. Can anybody explain how is it possible? advance appriciation for your effort
