Maintenance and Care Suggestions

Proper maintenance and care of these spare parts will extend their service life, reduce downtime, and ensure the reliability of your industrial equipment. Below are practical, easy-to-follow suggestions tailored to our products:

1. Weekly Routine Inspection

Check Harting connectors (19300241422, 9330242716) for secure connections and signs of damage; test DL MODEL JQ-4K transfer switch to ensure it switches power correctly. Inspect hydraulic cylinder E4019000001 for leaks; check air filters (106-3973, DF2-32 810502-00-0110) for clogging indicators. Verify Bendix AD-9 air dryer for proper moisture drainage; check seals (SCM-G0006037, SG180X210X18) for leaks.

2. Monthly Maintenance

Clean or replace filter elements (106-3973, DF2-32 810502-00-0110) if clogged. Lubricate BEARING-B604 NAICHI QUEST 6209-C3, Support bearing pad 533X23TC53B, and clevis pin PSZ75A-2-08 with high-temperature industrial grease to reduce friction. Inspect DOOSAN 65.01201-0312C liner for wear; clean and inspect the cylinder wall. Tighten fasteners and connectors if loose due to vibration.

3. Quarterly Maintenance

Replace complete set of oil seal SCM-G0006037 and OIL SEAL SG180X210X18 if they show signs of hardening or leakage.

On-Site Fault Maintenance Cases

Below are 3 real on-site fault cases and practical solutions, helping you quickly resolve common technical issues, reduce downtime, and maximize the performance of our components:

Case 1: XJ-450 Unit Hydraulic Instability (Support hydraulic cylinder E4019000001)

Fault Phenomenon: An XJ-450 drilling unit experienced unstable support, leading to rig vibration and unsafe drilling conditions.Analysis: Inspection revealed that the Support hydraulic cylinder E4019000001 had a leak in the piston seal, causing pressure loss. Solution: The cylinder was disassembled, the worn piston seal was replaced, and the cylinder was pressure-tested to ensure no leaks. Result: The XJ-450 unit regained stable support, vibration was eliminated, and drilling operations resumed safely. Tip: Inspect hydraulic cylinders monthly for leaks and replace seals every 12 months as a preventive measure.

Case 2: DOOSAN Engine Poor Performance (LINER DOOSAN 65.01201-0312C)

Fault Phenomenon: A DOOSAN engine experienced reduced power output, increased fuel consumption, and excessive smoke. Analysis: The DOOSAN 65.01201-0312C liner had excessive wear, leading to poor compression and inefficient combustion. Solution: The old liner was replaced with a new 65.01201-0312C liner, and the engine was tuned to ensure proper compression. Result: Engine power was restored, fuel consumption decreased by 14%, and smoke emissions were reduced. Tip: Inspect liners every 10,000 operating hours and replace if wear exceeds 0.1mm.

Case 3: TDS Hydraulic Jack Leakage (56519-12-12S Elbow O-ring boss)

Fault Phenomenon: A TDS hydraulic jack experienced hydraulic fluid leakage from the elbow connection, reducing jack lifting capacity. Analysis: The O-ring in the 56519-12-12S elbow had deteriorated due to high pressure and temperature, causing a leak. Solution: The old elbow was replaced with a new 56519-12-12S elbow, and the O-ring was inspected to ensure a tight fit. The hydraulic system was refilled with fluid and pressure-tested. Result: Fluid leakage was eliminated, jack lifting capacity was restored, and the jack operated normally. Tip: Inspect hydraulic elbows monthly for leaks and replace O-rings every 6 months.
