Maintenance & Care Suggestions

Proper maintenance and care can significantly extend the service life of components, reduce maintenance costs, and ensure consistent equipment performance. Below are practical, targeted suggestions:

1. Daily Inspection

Check the tightness of bolts (4300510020) and lock pins (9701200004) every 24 working hours, tightening them promptly if loose; inspect sealing components (ZJ32L 170×200×15 Spring Seal, 9722020331 Oil Seal) for oil or fluid leaks, replacing them immediately if damage is found; check filter elements (1R0770, 1R0749) for clogging, cleaning or replacing them when the pressure difference exceeds 0.3MPa; inspect drill bits (MD517GLM, DMS 1955BSNU) for wear, replacing them when the cutting edge wear exceeds 2mm.

2. Regular Lubrication

Lubricate bearings (6223, 3L1425), sprockets (P3500010AA), and crosshead bearings (A430129140061177017) every 600 working hours using industrial-grade lubricating oil or grease (e.g., 68# anti-wear hydraulic oil, lithium-based grease), ensuring lubrication coverage of 100% of moving parts; avoid mixing different types of lubricants to prevent reduced lubrication efficiency and component damage.

3. Periodic Replacement

Replace wearing parts according to service life: Filter elements (1R0770, 1R0749, ARIEL A-661), seals (ZJ32L 170×200×15, BKD-SR-5), and friction discs (W36-07-913) every 8000-10000 working hours; bearings (6223, 3L1425), pistons (83BDD), and drill bits (MD517GLM, DMS 1955BSNU) every 15000-20000 working hours; accumulator capsules (PSZ-NXQ-F6.3/200) and pressure regulators (3SJC-215) every 20000-25000 working hours. For components in harsh environments (e.g., drilling sites, well control areas), shorten the replacement cycle by 30%.

4. Storage & Handling

Store unused components in a dry, ventilated warehouse with a temperature of 0℃-25℃ and relative humidity ≤60%, avoiding moisture, corrosion, and direct sunlight; seal precision components (5N9292 Tachometer Sensor, YST-48R Silicone Oil 0208014) in waterproof packaging to prevent dust and damage; handle heavy components (L10VSO100DFLR/31R Piston Pump, 4445mm PDC Drill Bit) with care to avoid collision and deformation; store drill bits in protective cases to prevent damage to cutting edges.

On-Site Fault Maintenance Cases

Below are 3 real on-site fault cases, providing practical maintenance guidance to help users quickly resolve component-related issues, reduce equipment downtime, and improve operational efficiency:

Case 1: ZJ70DBS Drilling Rig Piston Pump Failure

Fault Phenomenon: The ZJ70DBS drilling rig L10VSO100DFLR/31R Piston Pump fails to deliver pressure, and the hydraulic system cannot operate. Fault Cause: Inspection shows the 83BDD Piston is worn (surface wear exceeds 0.2mm), and the ZJ32L 170×200×15 Spring Seal is damaged, causing internal leakage. Maintenance Solution: Replace the 83BDD Piston and ZJ32L 170×200×15 Spring Seal, refill hydraulic oil, and test the pump pressure. Result: The piston pump delivers pressure normally (30MPa), the hydraulic system operates smoothly, and the drilling rig resumes work.Key Tip: Check piston wear every 3 months, and replace it when wear exceeds 0.15mm.

Case 2: F-1000 Mud Pump Flow Reduction

Fault Phenomenon: The F-1000 mud pump experiences a 30% reduction in flow rate, with increased vibration and noise. Fault Cause: The 1R0749 Diesel Filter is clogged with impurities, and the 6223 Bearing of the pump shaft is worn, causing uneven rotation. Maintenance Solution: Replace the 1R0749 Diesel Filter and 6223 Bearing, clean the pump cavity, and adjust the pump alignment. Result: The flow rate returns to the standard value (800m³/h), vibration and noise are reduced by 25dB, and the mud pump operates normally. Key Tip: Check filter elements and bearings every 2 months when the mud pump is in continuous use.

Case 3: WNS1.0-1.25-Y Boiler Pressure Instability

Fault Phenomenon: The WNS1.0-1.25-Y boiler pressure fluctuates abnormally, and the pressure gauge shows inaccurate readings.Fault Cause: The 3SJC-215 Pressure Regulator is faulty, and the 380207012102506000 Vibration Pressure Gauge is contaminated. Maintenance Solution: Replace the 3SJC-215 Pressure Regulator, clean the pressure gauge sensor, and calibrate the pressure control range. Result: The boiler pressure stabilizes within 0-1.25MPa, the pressure gauge works accurately, and the boiler runs stably. Key Tip: Clean the pressure gauge sensor every month and check the pressure regulator’s performance every 3 months.
