Maintenance & Care Suggestions

Proper maintenance is key to extending the service life of mechanical parts and reducing replacement costs. Here are practical, easy-to-follow suggestions tailored to our products:

• Regular Inspection: Check ZJ70DBS hydromotors (TG0335MH460AAAA), ZJ50D combined hydraulic stations (RSD/Y-SFT70), and high-pressure ball valves (Q1INS-31.5-25) every 70 operating hours; replace worn or damaged parts (such as O-rings DQ70 2.4.51.026 and oil seals 5300200400) in time to avoid leaks or system failure.

• Cleaning & Lubrication: Keep hydromotors, pulley shafts (P2400128AA), and bearings (20616-1) clean; apply appropriate lubricating oil (matching the equipment manual) to reduce friction and prevent rust and wear.

• Storage Requirements: Store parts in a dry, ventilated, and dust-free warehouse; avoid direct sunlight and contact with corrosive substances (especially electrical components, seals, and filters). For high-pressure valves and hydromotor parts, store them in a cool, moisture-free environment to maintain their performance.

• Installation Notes: Ensure parts are installed correctly according to the equipment manual; avoid forced installation (e.g., aligning screws 4400200455 properly to prevent thread damage). For drilling rig components and hydromotors, follow OEM installation guidelines to ensure compatibility and safety.

• Filter & Seal Maintenance: Regularly replace torque converter filters (P170737) and air filters; check boiler servo motors (36962046) and pneumatic pressure transmitters (YPQ-40A) regularly to ensure safe and accurate operation; inspect seals and O-rings for wear and replace as needed to prevent leaks.

On-Site Fault Maintenance Cases

Here are 3 real on-site maintenance cases, showing how our parts solve practical problems for customers, reduce downtime, and improve equipment performance:

Case 1: Hydromotor Failure in ZJ70DBS Drilling Rig

A customer’s ZJ70DBS drilling rig experienced power loss and unstable operation due to a faulty hydromotor, leading to interrupted drilling. We supplied the ZJ70DBS Hydromotor TG0335MH460AAAA, which is fully compatible with the rig. After replacement, the hydromotor resumed stable power output, and the rig operated smoothly for 800 hours, reducing downtime by 85%.

Case 2: Hydraulic Station Malfunction in ZJ50D Drilling Rig

An oilfield’s ZJ50D drilling rig had unstable hydraulic pressure due to a worn component in the combined hydraulic station, causing hydraulic tong and winch operation issues. We provided the ZJ50D RSD/Y-SFT70 Combined Hydraulic Station, which is perfectly matched to the rig. After installation, the hydraulic pressure stabilized, and all hydraulic components operated normally, ensuring uninterrupted drilling work.

Case 3: Inclinometer Probe Leak in GE-MWD System

A well logging operation had inaccurate data due to mud leakage into the GE-MWD inclinometer probe, caused by a worn line plug. We supplied the GE-MWD Inclinometer Probe Upper End Line Plug 981992, which fits the probe perfectly. After replacement, the leakage was eliminated, and the inclinometer collected accurate data, improving well logging efficiency by 35%.
