FRL Lubricator Reservoir | Roll Forming Machine Pneumatic Oil Reservoir
FRL Lubricator Reservoir
1. Technical Definition
An FRL lubricator reservoir is the oil storage chamber located in the lubricator section of an FRL assembly (Filter, Regulator, Lubricator). It holds pneumatic lubricating oil that is introduced into the compressed air stream to lubricate pneumatic components such as valves, cylinders, and actuators.
The lubricator reservoir ensures a continuous supply of lubrication oil, allowing the lubricator mechanism to generate a controlled oil mist that travels with the compressed air through the pneumatic system.
In roll forming machines, FRL lubricator reservoirs are used in pneumatic systems supporting:
Pneumatic punching units
Air-operated valves and solenoids
Pneumatic cylinders and actuators
Air-powered clamping systems
General pneumatic control circuits
They help reduce wear and friction in pneumatic components.
2. Where It Is Located
The FRL lubricator reservoir is installed in the lubricator section of the FRL assembly, typically positioned after the filter and regulator stages.
Common installation locations in roll forming machines include:
Pneumatic air preparation units
Compressed air inlet systems
Pneumatic control cabinets
Air distribution panels
Machine pneumatic control manifolds
The reservoir is usually located at the bottom of the lubricator housing for easy oil refilling.
3. Primary Functions
3.1 Store Lubricating Oil
Holds the oil used to lubricate pneumatic components.
3.2 Supply Oil to the Lubricator System
Feeds oil to the lubricator mechanism for atomization.
3.3 Support Pneumatic Component Lubrication
Ensures moving pneumatic parts receive proper lubrication.
3.4 Enable Oil Level Monitoring
Allows technicians to visually check oil levels.
4. How It Works
The FRL lubricator reservoir supplies oil to the lubricator unit where it is mixed with compressed air.
Typical operation process:
Compressed air enters the lubricator unit.
Airflow creates a pressure drop within the lubricator mechanism.
Oil from the reservoir is drawn into the lubricator chamber.
The oil is atomized into a fine mist.
The oil mist mixes with the compressed air.
The lubricated air travels through the pneumatic system and lubricates internal components.
Technicians refill the reservoir when oil levels drop.
