Understanding Flow and Pressure in Auxiliary Hydraulics
Before diving into the adjustment process, it’s essential to understand what flow and pressure are, and how they affect your machine’s performance:
- Flow: Hydraulic flow refers to the amount of hydraulic fluid being pumped through the system, usually measured in gallons per minute (GPM). Higher flow rates are necessary when using attachments that require more hydraulic power, such as hydraulic hammers or augers.
- Pressure: Pressure refers to the force exerted by the hydraulic fluid. It’s usually measured in pounds per square inch (PSI). Pressure adjustments are important when you need more force from the hydraulics, such as when you're operating high-force attachments like shears or compactors.
Tools and Preparation
To adjust the flow and pressure settings on your CAT 315CL, you’ll need a few basic tools:
- Pressure gauge: To measure the hydraulic pressure during adjustments.
- Flow meter: To measure the hydraulic flow rate.
- Wrenches: For adjusting the control valves.
- Operator’s manual: It’s always a good idea to reference the CAT 315CL manual for specific settings and recommendations.
- Safety gear: Always wear appropriate personal protective equipment (PPE), including gloves and safety glasses, when working on machinery.
