The following are Types of Line in Technical Drawing EXCEPT _____.
People are willing to take proper care of what’s precious to them. An individual may take his car to the car engineer for servicing while another will call for the generator repair guy to service his generator. Often time, both devices (car and generator in this instance) are not necessarily in a completely bad shape but the fact remains that if left unchecked, a greater damage may result.
Any action that involves the servicing, checking, replacing and repairing of an equipment, object or device is known as maintenance
The goal of maintenance is either to prevent a breakdown or repair the breakdown. An individual may try to manage cost by carrying out maintenance before a damage or breakdown occurs. Please read our article on cost here.
Preventive maintenance is carried out routinely on a device even though no apparent fault may be present on such device. The goal of this maintenance as the name suggest is to prevent a sudden breakdown on a device or equipment. For instance, a person may take his car for servicing (monthly) even though the car is still able to work correctly. In the course of a preventive maintenance, worn out parts may be discovered and replaced as soon as possible. Also, there may be a change of oil while other little adjustments may also be carried out.
We can even carry out preventive maintenance on our body to prevent certain diseases. For this reason, some persons have discovered cancerous cells in their body through regular medical checkup; and were able to kill such cells before they become malignant. Preventive maintenance is considered to be the best form of maintenance.
Preventive maintenance may be defined as the routine check on an object or equipment before it fails or develops a fault
Corrective maintenance is carried after the breakdown of an object or equipment had occured. It may require a change of the damaged part or another form of repair on such damaged part. An example of corrective maintenance is when a knocked engine had resulted in a car failure. The car owner may need to buy a new engine which can be quite expensive.
Note: The goal of corrective maintenance is to correct the resulting damage.
We have heard news about collapsed buildings because the owners of such buildings took no account of preventive, predictive or periodic type of maintenance. The sad thing about this is “death” which may result before corrective maintenance is done. Now, imagine the amount of road accidents that would have been prevented if only we have properly working cars on our roads.
Corrective maintenance may be defined as the repairs that are carried out after the damage of an object or equipment had resulted
Some persons may be able to predict when a damage will result based on various signs. Nowadays, the development of technology has increased the rate of predictive maintenance. To achieve this, sensors are used to monitor the workings of various part of the equipment, object or machine. Please read our article on the internet of things here. The sensors send information about the impending damage to the user via a network. This maintenance is quite efficient in the way it works since it reduces unnecessary spending.
Predictive maintenance is the repair carried out on an equipment or object after a correct prediction of an impending fault
