Why a Dual Line Lubrication System Can be More Trouble Than It’s Worth

Attention all machinery enthusiasts! Have you ever considered using a dual line lubrication system for your equipment? While it may seem like an efficient solution to keep your machines running smoothly, there are some hidden drawbacks that could lead to more trouble than it’s worth. In this blog post, we will dive into the reasons why a dual line lubrication system might not be the best choice for your maintenance needs. So buckle up and get ready for some eye-opening insights on how to optimize your machinery performance!

Introduction

A dual line lubrication system is when two grease lines are used to supply grease to bearings. This can be done with a single pump or two pumps. The advantage of this system is that it can provide a continuous flow of grease and does not require manual intervention to keep the bearings greased. The disadvantage is that if one of the grease lines becomes blocked, the entire system will fail. This can lead to expensive repairs and downtime for your machinery.

What is a Dual Line Lubrication System?

A dual line lubrication system is a type of automatic lubrication system that delivers grease or oil to bearings and other moving parts in machinery. The system consists of two supply lines that are connected to a pump and reservoir. One line supplies grease to the bearings while the other line returns used grease back to the reservoir.

Dual line lubrication systems are commonly used in industrial and manufacturing applications where machinery is subject to heavy loads and high temperatures. The two lines ensure a continuous supply of fresh lubricant to the bearings, while the return line removes contaminated or excess lubricant from the system.

While dual line lubrication systems can provide reliable operation of machinery, they can also be more trouble than they’re worth. The system’s pumps and reservoirs need to be regularly maintained and replaced, and the two lines can become clogged with debris over time. In addition, the system’s sensors and controllers can fail, leading to unexpected shutdowns of machinery.

Disadvantages of a Dual Line Lubrication System

There are several potential disadvantages to using a dual line lubrication system. First, if one of the lines becomes blocked, the entire system will fail. This can be a major problem if the blockage occurs in a critical component, such as a bearing. Second, dual line systems are generally more complex and expensive than single line systems. This is due to the need for two pumps, two sets of valves, and other additional components. Third, dual line systems can be less reliable than single line systems. This is because there are more potential points of failure. Dual line systems require more maintenance than single line systems.

Common Issues with a Dual Line System

One of the most common issues with a dual line lubrication system is that it can be difficult to properly bleed the air from the lines. If air is not properly bled from the lines, it can cause problems with the system’s ability to deliver lubricant to the bearings. Additionally, if the system is not regularly maintained, it can become clogged with dirt and debris, which can also prevent proper lubrication delivery.

Alternatives to the Dual Line System

The dual line lubrication system is not the only option available for keeping machinery properly lubricated. Other options include single line and centralised systems. Single line systems are less expensive to install and maintain than dual line systems, but they may not be able to provide enough lubrication for very large or high-speed machines. Centralised systems are more expensive than either single or dual line systems, but they can provide a higher level of control and flexibility when it comes to lubricating different types of machinery.

Conclusion

A dual line lubrication system can seem like a great idea on the surface, but it can quickly become more trouble than it’s worth. The cost of installing and maintaining such a system is often not justified by the benefits that you will receive in return. Moreover, if any part of the system fails or becomes clogged, then you could experience serious downtime within your production process. In short, while dual line lubrication systems may have their advantages in certain circumstances, they should be evaluated carefully before being implemented as part of your business operations.
