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, designed to help you keep your equipment in optimal condition:

 Regular Inspection: Check Crane J40/2250DB brake valves (EQ140-3514E2-010), ZJ70 winch drive shafts, and ZJ50D filter elements (WU160×180) every 70 operating hours; inspect sealing rings (Z04120100002AA) and oil seals (9998) for wear or leakage, and replace them in time to avoid system failure.

 Cleaning & Lubrication: Keep winch drive shafts, gear pump components (P37), and roller shafts (ZJ50D28) clean; apply appropriate lubricating oil to reduce friction and prevent rust and wear. For filter elements and stuffing boxes, clean or replace them regularly to ensure efficient operation.

 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 (FKQ8006B) and crane parts, store them in a cool, moisture-free environment to maintain their performance and pressure resistance.

 Installation Notes: Ensure parts are installed correctly according to the equipment manual; avoid forced installation (e.g., aligning bolts BC136201 properly to prevent thread damage). For drilling rig components, crane parts, and mud pump components, follow OEM installation guidelines to ensure compatibility and safety.

 Filter & Seal Maintenance: Regularly replace filter elements (WU160×180, 1R0750) and air filters; check mud pump stuffing boxes (G029HS1A05A) for mud leakage; inspect brake pads (6y-9373) and clutch parts for wear and replace as needed to ensure safe operation.

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: Brake Valve Failure in Crane J40/2250DB Drilling Rig

A customer’s Crane J40/2250DB drilling rig experienced unstable braking due to a faulty double chamber brake valve (EQ140-3514E2-010), risking safety during load lifting. We supplied the Crane J40/2250DB Brake Valve EQ140-3514E2-010, which is fully compatible with the crane. After replacement, the braking system stabilized, ensuring safe lifting operations, and the rig resumed work with zero safety incidents, reducing downtime by 85%.

Case 2: Filter Element Clogging in ZJ50D Drilling Rig Hydraulic System

An oilfield’s ZJ50D drilling rig had reduced hydraulic system pressure due to a clogged filter element (WU160×180), causing hydraulic component malfunctions. We provided the ZJ50D Filter Element WU160×180, which fits perfectly with the rig’s hydraulic system. After replacement, the hydraulic pressure returned to normal, all components operated smoothly, and the rig maintained stable drilling operations for 750 hours, extending hydraulic component service life by 30%.

Case 3: Mud Pump Leakage in 10/8G-A H System

A drilling team’s 10/8G-A H mud pump had severe mud leakage from the stuffing box (G029HS1A05A), disrupting mud circulation and drilling efficiency. We supplied the 10/8G-A H Mud Pump HS1 Stuffing Box G029HS1A05A, which is compatible with the mud pump. After replacement, the leakage was completely eliminated, mud circulation resumed normally, and drilling efficiency improved by 40%.
