The Advantages and Benefits of an Automatic Lubrication System

Automatic lubrication system

Proper lubrication is essential for the smooth running and longevity of all types of machinery. Continually keeping a machine lubricated is costly in downtime and is often neglected or simply forgotten about.

This is why many plant and machinery operators rely on automatic lubrication systems. This article focuses on the many benefits and advantages of using an automatic lubrication system.

What is an automatic lubrication system?

Before we consider the benefits, it is helpful to understand the workings of an automatic lubrication system.

As the name suggests, an automatic lubrication system is designed to supply a precise amount of lubricant to moving parts while the machine is operating. This ensures that consistent and metered lubricants are delivered when and where a machine requires them.

Automatic lubrication systems vary in design from machine to machine, but there are typical components that most automatic lubrication systems share.

Automatic lubrication pump

The pump is the beating heart of an automatic lubrication system. It is responsible for providing the flow of lubricant and grease to the appropriate parts of the machine.

There are different types of pumps available that offer a range of pressure ranges and flow rates. The choice of pump is dependent on the type of machine and the lubrication requirements.

In some cases, the pump will also incorporate one of the other main components of an automatic lubrication system – A metering device.

Automatic Lubrication Metering Device

The metering device is what enables precise control over the frequency and amount of lubricant delivered to the machinery. It supplies preset doses of lubricant to a specific point or points as required.

As mentioned previously, a metering device can be integrated into the pump as well as being a standalone unit.

Automatic Lubrication Controller

The controller can be considered the brain of an automatic lubrication system. These are programmable computers that use sensors to detect, monitor, and control the flow of lubricants through a system.

As well as using sensor inputs to monitor the system, the controller is also programmed with the required lubrication schedule. Again, the controller is a component that is often combined with the pump unit.

Automatic Lubrication System Fittings

Finally, there are the fittings and tubing that comprise the plumbing of an automatic lubrication system. The tubing should be selected carefully as it requires to be of the correct calibre to safely handle the required lubricant.

Other Lubrication System Parts

The above are the main components of an automatic lubrication system. But depending on the machine and individual requirements, there are optional components that could be required. There are too many of these to list, but a few examples are noted below:

  • Filters for grease, oil, or air
  • Various additional sensors (pressure, stroke, cycle)
  • Valves

Benefits and Advantages of an Automatic Lubrication System

In comparison to manually lubricating machinery, there are many advantages to automatic lubrication systems. A few of the main ones are listed below:

Reduced Costs due to Reduced Downtime

Automatic lubrication systems reduce the downtime of a machine, and less downtime means lower costs. They reduce downtime in several ways, including:

  • Reduced maintenance – Improperly lubricated machinery requires more maintenance. Automatic lubrication systems ensure that the correct lubrication is always applied
  • Minimise Interruptions – Because automatic lubrication systems continually lubricate as the machinery operates, there are fewer breaks in the productivity cycle of a machine

Improved Temperature Control

Reducing operational temperatures is critical for a machine to run optimally. Lubricants draw heat away from vital components and allow it to dissipate and, in doing so, ensure that the machine is always running at optimal temperatures.

Improved Lifespan and Reliability

Because machines that operate with automatic lubrication systems always have the optimal lubrication, friction and wear are greatly reduced. For the operator, this results in fewer repairs and the ensuing expense, but also it greatly improves the useful lifespan of any machine.

Protects against corrosion

Damp climates such as Ireland’s allow for corrosion to quickly get a hold and spread unchecked wherever it is allowed to. Automatic lubrication systems can help keep vital components corrosion-free.

Alongside the benefits of automatic lubrication systems, regular maintenance tasks like DPF cleaning are also crucial for the longevity and efficiency of your machinery, especially those with diesel engines.

Summing Up

Rather than being an additional cost, an automatic lubrication system will save money by prolonging the life of machinery, helping it work more efficiently, preventing breakdowns, and reducing downtime.
