Preventive Maintenance

Preventive maintenance is an observation systematically accompanied by technical-economical analysis to ensure the proper functioning of the equipment production and extend the life of the equipment in question. The purpose of preventive maintenance is to be able to achieve a level of maintenance of all the equipment production in order to be retrieved an optimum product quality.

Preventive maintenance is the routine maintenance is done to prevent the occurrence of the damage before the age of disposable (life time) the equipment comes to an end. Preventive maintenance is usually based on the hours of operation of the equipment. The types of preventive maintenance can be grouped up:

Oiling

 

Oiling is the Act of granting of oil moving components, the use of oil in General for those parts of the covered equipment such as gearbox. Awarding of oil consists of replacement and addition. This type of oil is used for each piece of equipment is no the same depending on the working conditions of such equipment.

For working conditions with high temperatures such as the turbine used oil Turbo T46, as for the hydrolic power pack and hydrolic system more use oli Turalik 52 Meditran Oil or SAE 10.

 

Greasing

 

Is the process of adding and replacing the grease, usually using a grease pump (potty). Grease used for bearing, bushing and shaft.

Replacement

 

Replacement parts routinely done in accordance with the initial design of the equipment, in accordance with the age-of-. Replacement of these parts to ensure the optimization of overall unit labor. As replacement filters in diesel engine.

Setting

 

Select done to return the equipment to its original condition, so the work equipment is still the optimal. Like setting the rotor bars with kerenggangan plate on the unit's ripple ripple mill according to the efficiency of the equipment, damper settings separating colomb, secondary separating colomb and LTDS.

 

other maintenance activities also include, in more detail :

Inspection (inspection), periodic maintenance activities is to check the condition of the equipment components and production equipment around the area of production equipment. See, a sense of, listen, maintenance activities is to check the condition of the equipment through vision, feeling and hearing.

Maintenance runs (running maintenance), maintenance activities are carried out without mengehentikan of work equipment.

Small component replacement (small repair), maintenance activity is in the form of small component replacement.

Maintenance stop (shutdown maintenance), is the maintenance can be done only at the moment of equipments of production stops.

By utilizing good maintenance procedure, where the going good coordination between the production and maintenance will be retrieved:

Quantity of production equipment Stop may be reduced (down time reduced production equipment)

An expensive repair costs can be reduced

Interruptions to the schedule planned production time and maintenance can be eliminated or reduced.

One of the goals of Preventive Maintenance is to find some degree of circumstances showed symptoms of damage before the tools were fatal damage. This can be done by making the planning and scheduling of maintenance activities with minimal interruption of the production process.

Basically not enough just by making planning scheduling (scheduled maintenance) a mature but noteworthy efforts to focus attention on the units of production equipment that is considered vulnerable and critical. A qualifier against a prone unit based on:

Damage to the unit can endanger the health or safety.

Damage can affect the course of the production process and product quality.

The damage can cause the production process at a standstill.

The capital unit is rated high enough.

To maintain or inspect entire unit strictly regular and just eliminate the possibility of damage to the production equipment is a business which is not practical because it requires human-human with high requirements and costs are not a bit. Due to the shape and wake disorders it is very difficult for an estimated early, then the maintenance needs to be done regularly and periodically from time to time against all the unit installation. To do so required the maintenance efforts include, among others, :

Routine maintenance

Maintenance (its improvement) small/medium

Dismantle entirely (overhaul)

Routine maintenance is maintenance effort against the installation of units carried out routinely and periodically with a fixed interval of time implementation and brief.

The type of work included in the routine maintenance is basically a maintenance effort done without dismantling process melelui. Forms of work in the maintenance routine among others is:

A routine inspection is a review of the physical condition of the visually to components of the installation equipment production unit. This work is usually done regularly every single day until one week once, Depending on the needs.

Routine testing, It is an attempt to regulate or monitor the working condition of a component is divided so that routine component can be organised to operate in normal conditions.

Common activities done in routine maintenance for example :

Check the function of the components of the mechanism

Check and adjust the (adjustment)

Clean Up

Tighten loose parts

Maintenance of the small/medium business is mild improvements of symptom disorders who successfully detected during a routine check. Improvement of light is very important role in achieving the success rate of the maintenance process performed against a component unit installation.

Activities on the engine Overhaul is typically done periodically and very regular and had a concentration and attention more than routine inspection and maintenance of small. This activity is carried out on the machine to check the condition of the dismantling of the components of the machine as a whole which is intended to find out the possible damage that occur on machines that cannot be known simply by a routine check. Examples of such activities, for example on the replacement of refractory stone in cement factory kiln/furnace.

In addition to do maintenance with planning and scheduling a mature, in the preventive maintenance known activities are often referred to as predictive maintenance (predictive maintenance) that can be interpreted as a maintenance strategy where its implementation is based on the condition of the equipment of production itself

Given the level of certainty 100% There has never been so people prefer to use the term prediction or forecast to make sure his opinion. In guessing the program basically needed the support of data and knowledge deep enough about the behavior of the production equipment of the observed.

Some examples of support knowledge needed to anticipate this situation among others :

Mastery of the principles of the work of the corresponding tools.

Mastery characteristics tool.

Experience of operation of the same tools in the past either by yourself or someone else.

Mastery and proper data retrieval.

Mastery of data processing.

Ability to correlate between a single instance with another occurrence in relation to the field maintenance.

Insightful in the fields of equipment related to the production of technological advances.
