How A Dual Line Lubrication System Can Replace The Old Manual Adjustments

With the enormity of the task in the sugar mills, rolling mills, steel mills, mining, melting plant, cement plants, power plants, mining, large machines, breweries, stackers, reclaimers, etc., India has seen a rising need of a robust lubrication system or better say a two line lubrication system.

A two line or a Dual Line Lubrication System, like the single line parallel system, also uses hydraulic pressure to cycle adjustable valves to dispense measured shots of lubricants. But the exception lies in its two main supply lines that are laid parallel to the equipment to be lubricated.

In an effort to provide you some guidance on the lubrication processes across various industry sectors, this article will focus on these two line lubrication systems only.

The System:

As the name suggests, a dual or Two Line Lubrication System has 2 main supply lines which are alternatively used as the pressure or vent lines. Its end-of-line pressure switches are used to control and monitor the system.

You can utilize its two main lines that are supplied alternately with lubricant from a high-pressure pump via a changeover valve at up to 400 bars. The advantage of this system is that it can be used on large systems with dispersed lubrication points that require varying lubrication quantities.

Metering Device:

The dual-line or Two Line Metering Device uses its four outlet feeding ports to transfer lubricant by a lubrication pump where the changeover valve connects in its main line.

Following are some advantages of these devices:

1. The high quality of raw materials used in the valve makes the operation reliable.
2. The standard industrial installation dimensions make the equipment easily replaceable.
3. Each product is strictly tested with thin testing oil.

Interestingly, the two-line lubrication system can also be combined with these metering devices, increasing the total number of lubrication points that are served by a two-line metering device.

Gazillions of Advantages:

The Two Line Lubrication Systems can promise you a heavy duty mechanism for any type of industry.

Let’s look at their precise advantages…
i) Large systems with dispersed lube points
ii) Varying lubrication quantities
iii) Ideal for rigorous conditions
iv) High pressure capability reduces installation and material costs.
v) Problem-free readjustment after installation.
vi) Reliable and easy to extend or reduce

The key advantage of a two-line system lies in its supply of an exact metered quantity of lubricant over large distances. It automatically regulates the pressure and compensates for temperature fluctuations resulting in a longer service life of the pump and other system components.
