A pump is built to certain specifications so it can with stand what is going through it and what is happening around it. But bearings that allow the pump to run are made to handle loading conditions only. It is said that bearings are the heart of the pump. If a bearing is gone, the pump does not run and no product is pumped. Then an unfavorable condition will occur, which may cause many problems, most of which are inconvenient and costly.
If bearing is the heart of a pump, then lubricant is the life blood. Therefore, it is necessary for you to pay attention to the pump bearing lubrication. Pump bearings can be lubricated manually, or with a centralized lubrication system, or by smaller multi-point lubricators. It is known to us that nearly 50 percent of bearing failures are caused by improper lubrication (either under or over-lubrication).
Thus, it is very important to choose the appropriate way to lubricate.
Pump bearings can be somewhat problematic when it comes to proper lubrication. One of the biggest issues is that a traditional bearing lubrication system is inadequately designed for optimum lubrication. For example, in oil lubricated bearing the oil level is typically viewed through a sight glass. The oil level reading must be taken when the pump is off and on level ground. It must be maintained at the midpoint of the lowest roller to prevent overfilling which can lead to extreme heat generation.
As an alternative, automatic lubrication delivery systems can be a viable option to the problems associated with manual lubrication.
Automatic lubrication can range from a lower-cost single-point lubricator to sophisticated centralized lubrication systems. In addition to this, centralized lubrication systems offer the ability to lubricate entire systems and offer a permanent solution. Another advantage is that one system can serve an entire plant, provided the same lubricant is being used for all of the lube points.
There are still many other ways of lubrication. How to choose the right one? It depends on your needs. Remember to consider and compare all different factors when selecting the proper lubrication system to meet your unique operating conditions and maintenance intervals.
