Every day millions of m³ of wastewater are produced that must be treated in treatment plants. Wastewater, after treatment, is typically returned to the ecosystem from which it was removed, which is why treatment plants have a vital importance for both humankind and the environment.
The non-stop operation of treatment plants means that individual components are subjected to stress and strain. Pollution and the humid, wet environment further add strain to the application, thereby placing enormous challenges on the condition of the individual equipment and components.
Wear on bearings is especially high. It starts at the pump stations which usual comprises long worm gear units. Their bearings typically don’t hold much lubricant, which is why they need to be lubricated frequently. With a manual grease gun it is difficult to exactly meter the lubricant, and on top of this, the lubrication nipples are hard to get to. When lubricant is lacking, the bearing will seize and the repair is tedious and expensive.
Such problems don’t just exist at the inlet worm gears, but also at the grit and grease capture areas, or especially on the chain-racks in the pre-treatment tanks or basins. Because they run permanently in water, if the seal of the drive and turn-around chain wheel fail, or there is inadequate lubrication, the shaft will break. Such breakages are not uncommon.
As a result, special attention should be paid toward maintenance tasks, which incorporate a proactive, preventative maintenance concept, designed to prevent unplanned cost and downtime.
A Lincoln centralised lubrication system helps the treatment plant operator achieve a more reliable, economical, safer and more productive operation. Whether there is one lubrication point or several hundred. Lincoln lubrication systems are always individually suited to the requirements of each special application.
A lubrication system consist generally of a reservoir in varying capacities, with a stirring paddle that keeps the grease “lubricatable” even at freezing temperatures. A piston pump supplies so called progressive metering devices, from which up to 22 lube lines can go to the lubrication points. The system can be divided into different lubrication circuits thereby taking into account different lubrication intervals and required quantities. Lubrication occurs in precise predetermined intervals with an exact metered amount. As a result, bearings are not over or under filled.
Centralized Lubrication System Benefit
- Prolong wear and corrosion with appropriate lubrication
- Prevent the ingress of water and contamination into your bearing by maintaining a protective grease barrier.
- Supply your bearing with the optimum lubricant quantity in frequent intervals while the equipment is in operation
- Increase overall plant safety
