Common faults and troubleshooting of water well drilling rig hydraulic systems

Hydraulic systems are prone to faults like abnormal pressure or slow movement.water well drilling rig . Timely fixes ensure normal rig operation.

 

  1. Insufficient system pressure: Weak drill rotation, slow pipe lifting. Causes: pump wear, low relief valve pressure, loose joints. Check oil level first; test pump pressure. Clean or replace valves/pumps if needed. 例如, dirty oil jamming valves—cleaning restored pressure.
  2. Slow actuator movement: Sluggish cylinders, slow motor rotation. Causes: blocked throttle valves, contaminated oil, motor wear. Check filters, clean valves. Test motor torque; replace if necessary. A crawler rig’s motor regained normal speed after replacing worn plungers.
  3. Severe system overheating: Oil over 60℃ harms viscosity and seals. Causes: blocked coolers, high pressure, wrong oil. Clean coolers, check pressure, replace oil if needed. A rig’s overheating stopped after cleaning dust-clogged coolers.

Regular preventive checks cut faults, boosting water well drilling rig efficiency.
