There are following types of maintenance of a water and water pump:
This type of maintenance is needed when a part of the pump stopped working. However, it is easy to fix as you just need to replace the part. You must have water pump accessories in your basement. These extra accessories so when an accessory fails, you can fix it immediately. It is the most cost-effective option as you do not need to visit the market for buying the part.
This type includes steps that you need to take to prevent the entire unit from failing. Anyhow, there are many cost-effective options to choose from.
In this type, a user can calculate the time remaining to failure to predict when the problem can occur. For this, you need to collect a lot of data which you need to use effectively. If you see that the time is coming then you can extend the limit to put it back to reactive maintenance.
Basically, you take constant readings to note any kind of change in the equipment. You are constantly reading the changes and note them. Using this data, you can predict the possible failure. For this, a pump can have fault-tolerant controls that note readings and automatically adjust the pump speed to avoid it.
As a responsible pump user, you need to set up files for each of the pumps. It can help you increase the effectiveness and to prevent maintenance of the water pump.
You need to store data such as flow rate, efficiency, input power, pump head, and speed. Also, need to make performance curves that include, NPSHR vs flow rate, efficiency vs flow rate, input power vs flow rate, etc. Moreover, the supplementary data and specification sheet at the time of purchase. Moreover, you should include installation and maintenance instruction by the manufacturer in these files.
Where to Concentrate Maintenance Resources
It is always better to have resources to apply fault-tolerant controls to every pump you have. But these resources are not cheap and are limited. So who we should use these limited resources to maximize the reliability of the pump? We can do this by following these steps
In the first step, we need to set all the records and should know the MTBF for every pump. After that need to determine the MTBF of all the pumps by dividing the number of pumps with a total number of repairs and then multiply it by time period. The pumps that are using most of the resources should be top on the priority list.
In the second step, you need to concentrate on the components of the pumps that have a high failure rate. Bearings and seals are those components that have a high failure rate.
In the last step, those who have low MTBF value should be examined to find the root cause of the problem. Finding the root cause is the only way to improve the performance of the pump.
