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 ZJ50D RDS-8T combination gas pipelines, Sullair 02250100-756 oil-gas separators, and high-pressure stop valves (QST140-J) every 80 operating hours; replace worn or damaged parts (such as O-rings 530301190240024001 and sealing rings CS33001-0305) in time to avoid leaks or system failure.

• Cleaning & Lubrication: Keep rotor bearings (5S4557), cardan shafts (ZJ-45 SWC315BH-1410), and bushings (AG375001-1112B2) 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, O-rings, and filters). For high-pressure pipelines and Sullair oil-gas separators, 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 stud bolts T500-4015 properly to prevent thread damage). For Sullair parts and drilling rig components, follow OEM installation guidelines to ensure compatibility and safety.

• Filter & Separator Maintenance: Regularly replace filters (ZJ70DB 5208000131 WU250×100, IA-192 CUNO) and filter elements (20514654); clean the Sullair 02250100-756 oil-gas separator regularly to maintain separation efficiency and extend compressor service life.

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: Oil-Gas Separator Failure in Sullair Compressor

A customer’s Sullair air compressor experienced oil carryover due to a faulty non-original oil-gas separator, leading to reduced compressor efficiency and increased oil consumption. We supplied the Sullair 02250100-756 Oil-Gas Separator (Outside), which is fully compatible with Sullair specifications. After replacement, the separator effectively separated oil and gas, reducing oil consumption by 30% and restoring compressor efficiency to optimal levels.

Case 2: Hydraulic Filter Clogging in ZJ70DB Drilling Rig

An oilfield’s ZJ70DB drilling rig had hydraulic system pressure loss due to a clogged inlet oil filter, causing slow operation of the winch. We provided the ZJ70DB Inlet Oil Filter 5208000131 WU250×100, which is designed for ZJ70DB hydraulic systems. After replacement, the hydraulic pressure was restored, and the winch operated smoothly, reducing downtime by 75%.

Case 3: Gas Pipeline Leak in ZJ50D Drilling Rig

A ZJ50D drilling rig’s gas system had a leak in the combination gas pipeline, risking safety hazards and disrupting drilling operations. We supplied the ZJ50D RDS-8T Combination Gas Pipeline, which is perfectly matched to the rig. After installation, the leak was completely resolved, and the gas system operated safely and stably, ensuring uninterrupted drilling work.
