Grohall specializes in tailored, targeted recommendations for critical lubrication and petroleum equipment used by the mining and industrial sectors. Our team has the expertise, knowledge, and background to help your facility ensure your automatic lubrication system components are functioning safely and in harmony. We can help you troubleshoot common issues, keep up with critical maintenance, and replace core system parts to reduce downtime and lower the risk of safety hazards. Here is an engineering-level checklist for the spec, installation, and troubleshooting of automatic lubrication systems designed for the mining and industrial sectors. 

Specs and Design

Your infrastructure and system must be precisely engineered to be compatible with the requirements of your machine and related components. To ensure this happens, you must:

• Lube Point Audit – Conduct a lube point audit to identify every point and calculate its precise volume
• System Type – Select the optimal system type: Single-line progressive for compact drills or any equipment that necessitates precise, sequential delivery; dual-line systems for large-scale equipment that requires long-distance delivery.
• Environmental Rating – Ensure equipment is rated for the optimal temperature range as well as resilient to high-vibration environments.
• Lubricant Compatibility – Verify the NGLI grade for pumpability and dropping point specifications.
• Reservoir Sizing – Match the capacity to the maintenance cycle of the machinery.

Installation   

You can reduce the risk of system failure or injury by ensuring proper installation:

• Follow all protocols for isolation before beginning, making sure all electrical, hydraulic, and pneumatic energy sources are locked out
• Inspect distribution lines for kinks and verify tube lengths 
• Avoid over-torquing divider valve mounting screws
• Test all control panels, safety interlocks, and sensors before running the machinery under load
• Follow air bleeding protocols to remove trapped air

Troubleshooting   

We recommend that you take a measured, precise, and systematic approach to troubleshooting. This will maintain environmental safety and lower the risk of accident, injury, and spills:

• High Pressure – Pressure issues could be caused by a blocked line or bearing or hardened grease. Inspect the visual indicator pins to look for a popped pin. Check for weeping at connections. Check pump voltage.
• Inconsistent Delivery – Uneven lubricant distribution may be a sign of metering valve wear and tear or debris. Clean or replace all metering devices and verify timer settings. Lubricant separation can be caused by high heat. Check the dropping point and flush the system then replace lubricant with a high-temp synthetic.
• Pump Priming Faults – A pump not priming may be due to an air lock or empty reservoir. Refill the reservoir or bleed air from the pump’s outlet.
• Metering Issues – May be caused by physical blockages, air entrapment, or damage. Look for signs of hardened grease, foreign matter, or clogged strainers
• Line Routing and Fitting Problems – Look for signs of over-torqued mounting or internal leakages. 
• Incorrect Controller Settings – Faulty sensors or incorrect control unit settings can trigger alarms. Check settings against manufacturer recommendations and industry standardized settings.
