A Centralized System for Lubrication


As mechanical parts are subject to friction, they require thick commercial lubricants portland or like grease or oil to prevent wear and tear. The challenge is to keep the right amount of viscous liquid supplied to the parts at the right time. Whether you’re lubricating a construction vehicle’s axles or oiling a line of presses and other production equipment, these lubrication systems offer increased precision and less human error risk, particularly when multiple machines and parts are involved.

Central systems require lubrication components

A centralized lubrication system’s layout depends on the type you choose. The components and their layout can vary depending on whether you have a single-line progressive setup or a dual-line parallel setup. However, most systems include the following basic components:

  • The pump
  • The controller
  • Line of supply
  • Air intakes
  • The injectors
  • Lines of feed
  • Switch for pressure

The Workings of Central Lubrication

A controller and injectors are programmed to deliver specific amounts of oil or grease at specific intervals. In order to apply the lubricant, the controller activates the lubricant pump. By pumping air into the lines, the viscous liquid is moved through the supply line and into the injectors under pressure. Upon delivery of the preset volume, a pressure switch deactivates the pump, and any remaining lubricant is directed back to the reservoir.

A number of technological advances have improved the efficiency of the central lubrication system, including alarms for injectors, plumbing, and reservoirs. Operators receive alerts when normal operating conditions or fluid levels differ from normal.

In addition to increasing operational efficiency, the alerts reduce the risk of machinery damage by notifying technicians when preventive maintenance is required. To extend the time between scheduled maintenance, our team can also provide high-capacity reservoirs.

Positive Displacement Vs. Flow Proportioning

A centralized lubrication system can either be positive displacement or flow proportioning. The method of injection differentiates them. Flow proportioning uses smaller orifices to restrict lubricant flow, while positive displacement uses metering pistons. We have an experienced team of engineers at Dropsa USA who can help you design the right system for virtually any application.

There are a few considerations to keep in mind when selecting the right central lubrication system. It is important to consider the weight of the lubricant and the distance that it must travel from the central reservoir to the injection points. Distance from the reservoir and viscosity of the liquid affect the time it takes to vent after injection.

A Few Types of Lubrication Systems

If you need a centralized lubrication system for a commercial or industrial application, choose one of these common types. You can compare each of these types to find the right lubrication system whether you have one vehicle or a fleet of machines:

  • The minimum quantity of lubrication is
  • Recirculation lubrication of oil
  • Loss of total lubrication
  • Liquid air/oil lubrication
  • System for centralized grease lubrication

The minimum quantity lubrication process is one of the latest innovations in efficient lubrication. To deliver the correct amount of lubricant for the project, these systems use precision injectors. CNC machines use them to keep cutting at peak efficiency.

In oil recirculation systems, equipment can be completely submerged in oil. As with an automobile transmission, this system circulates the same oil until it needs to be emptied and replaced.
