Lubrication System or better known as Progressive Lubrication System enables lubrication of various parts of a machine on specific time intervals that ensure an effective functioning of the machine, without ceasing its working.
Automatic Lubrication System consists of a Timer/controller, a reservoir & pump, a supply line, metering valves & injectors as well as feed lines. Each of its components have a unique function which play a pivotal role in lubricating the part or point of application in/on the machine. The Lubrication System are of various types. Let us have a look at a few of the most popular Lubrication System:
This system uses the lubrication flow in order to empower the specific metering valve or assemblies of metering valves. The lubrication system commences when the controller/timer is turned on. On turning on, the system begins pumping the lube via the supply line that interconnects the primary metering valve. The lubricant is stored at various points and incessantly the process of lubrication continues via the secondary progressive metering valves followed then promptly to each point through the feed lines.
The Dual Line Parallel Lubrication System uses hydraulic pressure in order to empower the adjustable metering valves to dispense and distribute specific volumes of lubricant.
A dual Line Parallel Lubrication System consists of two chief supply lines that are alternatively utilized as vent or pressure lines.
This Dual Line Lubrication system benefits in the way that innumerable lubrication points on a machine can be handled single-handedly by a pump station, which is situated over hundreds of thousands feet with the help of various smaller tubes or pipes.
As the controller/ timer is turned on, the lubrication cycle commences with the pump that starts pumping lubricant in order to build up a consistent pressure in the first supply line while subsequently venting the second supply return line. As soon as the favorable required pressure is achieved, a specific amount of lubricant is secreted by the metering valves to the half of the lubrication points. This process of distribution is undertaken via the feed lines.
The system hydraulically shuts off once the pressure switch monitoring the main supply line pressure has reached a preset pressure level. The pump is then shut off & the signal once again changes over the metering valves to redirect lubricant in the secondary chief line of supply. Thus when the controller is once again turned on. The previous primary supply line now becomes the vent tile and the secondary supply line plays the role of the primary supply line & the whole system is rerun.
The Single Line Parallel Lubrication System is quite similar to the Dual Line Parallel Lubrication System. This system was introduced in 1937 by the Lincoln Industrial in the US.
This system like the Dual Line Parallel Lubrication System uses hydraulic pressure as well, the only difference being that the single line lubrication system is more preferable when the volume of lubricant dispensing is variable that is it varies for different points. Single Line Lubrication System includes a central pump station that automatically dispenses the lubricant to various parts of the machine through a singular chief supply line to the multitude injector outlets. These injectors work independently & individually self-adjust the required volume of lubricant to be dispensed.
In addition to the three main types of Lubrication Systems, there are others like single Point Automatics, Single Line Resistance, Oil-Mist & Air-Oil Systems, Oil Re-circulating systems & Chain Lube System.
