Daily Maintenance of Hydraulic Core Rig: 20 Years of Experience from a Veteran Operator​

Publication Date: Jun 26, 2025

With over two decades of core drilling experience, I can confidently say that 90% of hydraulic core rig failures are caused by neglecting daily maintenance of hydraulic core rig. Today, I’ll share my hard-earned insights on daily maintenance of hydraulic core rig in plain terms.

1. The "Three Checks" You Must Do Every Day

The foundation of daily maintenance of hydraulic core rig lies in these three actions:

(1) Hydraulic oil check: Inspect oil levels when the machine is cold (mid-mark on the dipstick is ideal). If foam is present, investigate air ingress immediately.

(2) Hose inspection: Feel all hoses for bulges or leaks (replace immediately if found), especially at bends.

(3) Fastener check: Use a wrench to tap critical bolts (rotary head, feed cylinder, track rollers).

This daily maintenance of hydraulic core rig routine has saved me from three major breakdowns.

2. Special Care for the Hydraulic System

The top priority in daily maintenance of hydraulic core rig:

(1) Filter maintenance:

① Clean pilot filters every 100 hours (soak in diesel and air-dry).

② Replace return filters every 250 hours (don’t wait for warning lights).

(2) Oil temperature control:

① Install auxiliary coolers in summer (shut down if oil exceeds 65°C).

② Switch to low-temperature oil in winter (HV46 for -25°C and below).

These daily maintenance of hydraulic core rig details can extend pump life by 5 years.

3. "Longevity Secrets" for the Rotary Head

Often overlooked in daily maintenance of hydraulic core rig:

(1) Bearing lubrication: Grease every 50 hours (use a high-pressure grease gun).

(2) Seal inspection: Watch for leaks during drilling (leaks wash away lubricant).

(3) Abnormal noise check: Normal operation sounds like a steady "hum"; stop immediately if "clunking" occurs.

This daily maintenance of hydraulic core rig method kept my rotary head running for 8 years without major repairs.

4. Maintenance Tips for Special Conditions

Upgrade your daily maintenance of hydraulic core rig for these scenarios:

(1) Dusty environments (mines/deserts):

① Blow out air filters daily (use 0.3MPa compressed air).

② Cover electrical connectors with dust caps.

(2) High humidity (coastal/rainforest areas):

① Apply anti-rust grease to exposed metal.

② Place desiccants in electrical cabinets.

(3) Extreme cold (below -30°C):

① Add -35# anti-gel to diesel.

② Preheat hydraulic oil to 15°C before startup.

5. Easily Overlooked Details

Advanced daily maintenance of hydraulic core rig includes:

(1) Hose lifespan management:

① Mark installation dates on hoses (replace every 2 years).

② Store spare hoses coiled (never folded).

(2) Electrical wiring protection:

① Secure all wiring with cable ties (vibration causes wear and shorts).

② Keep spare fuses of all types in the fuse box.

(3) Long-term storage prep:

① Retract all hydraulic cylinder rods (prevents corrosion).

② Remove and charge batteries separately.

Advice for Beginners:

(1) Keep a maintenance log (date/item/issue/responsible person).

(2) Always have in your toolbox:

① Hydraulic line plugs (for emergency replacements).

② Magnetic pickup tool (for dropped bolts).

3. Take photos before disassembling anything.

Remember: Every minute saved on daily maintenance of hydraulic core rig will cost you double during a breakdown!
