The service life of a mud pump is closely tied to model selection, operating standards, maintenance routines and adaptability to site working conditions. Scientific and standardized management can greatly extend equipment durability, detailed solutions are listed below:
1. Standardized Operating Procedures
① Pre-start Inspection
- Check for blockages in inlet and outlet pipelines; make sure the suction pipe, foot valve and pump chamber are fully filled with water; fill the pressure gauge buffer with lubricating oil.
- Test clutch flexibility; rotate the piston manually to confirm no jamming; inspect circuit insulation before startup.
② Running Control
- Equip a high-pressure clean water pump (pressure higher than mud pump working pressure) to flush packing assemblies and prevent seal abrasion.
- Keep mud sand content ≤10%; stop operation and clean immediately if the limit is exceeded to avoid accelerated liner and impeller wear caused by solid particles.
- Shift through multiple gears during each shift; maintain single gear operation for at least 30 seconds to guarantee uniform splash lubrication.
③ Shutdown Maintenance
- For long-term storage, disassemble the pump, fully remove residual mud, coat anti-rust oil on metal parts and store in dry, ventilated warehouses.
2. Systematic Daily Maintenance
① Wearing Parts Inspection & Replacement
- Replace sealing rings every 3 months; inspect cylinder liners and pistons every 2000 working hours; replace components when wear thickness exceeds 0.5mm.
- Adjust the gap between impeller and wear plate via rear bearing housing screws; follow official drawing standards (0.5–1.2mm normally) to avoid vibration damage.
② Lubrication & Cooling Management
- Refill gearbox lubricant every 500 hours; apply grease to crosshead tie rods at the end of each shift.
- Check cooling water cleanliness weekly; clean radiators when water temperature exceeds 60℃ to avoid high-temperature ablation.
3. Fault Prevention & Technical Upgrades
① Abnormal Fault Response
- Stop the pump immediately if severe vibration or abnormal noise occurs; check for impeller blockage, bearing wear or uneven assembly clearances.
② Anti-Wear Structural Modification
- For hard rock drilling projects, spray tungsten carbide coating on piston surfaces to extend service life by 40%; control crosshead and tie rod coaxiality error within ≤0.05mm.
③ Intelligent Monitoring Upgrade
- Install pressure and temperature sensors to monitor real-time pump operating data; match with frequency conversion control to dynamically adjust rotating speed.
