Function Description
Each component is designed with a specific operational function to solve identified industry pain points, with a focus on durability, precision, and system integration.
Filtration & Pneumatic Components
Filtration systems are the first line of defense against wear. The 321-4686 Breather features a multi-layered mesh structure that filters 99.9% of airborne dust and moisture, preventing reservoir contamination. The 326-1644 Separator Filter utilizes centrifugal separation and coalescing filter media to achieve an oil removal efficiency of 99.7%, protecting downstream air tools from corrosive oil mist. The 250025-526 Element offers a 5-micron filtration rating, ensuring clean air for pneumatic tools.
Valves & Actuation
Valves control the lifeline of fluid power. The 4900350088 XJ045SJHZC016 Valve for XJ-450 units provides positive manual positioning of hydraulic flow, with a pressure rating of 35MPa and a service life of over 50,000 cycles. The Solenoid Valve 4v210-08 offers fast response (<0.05s) and is compatible with both DC and AC power supplies, making it ideal for automated drilling control panels.

Maintenance & Care Recommendations
Proactive maintenance is key to maximizing the service life of your equipment. Below are guidelines based on typical operating cycles.
Filtration Components
• 321-4686 Breather: Inspect monthly; clean the element if contaminated. Replace every 6 months or 1000 operating hours.

• 250025-526 Filter: Replace element during every standard compressor service, typically every 2000 hours.
Valves & Actuators
• 4900350088 Valve: Lubricate the stem with high-pressure grease every 3 months to prevent sticking. Inspect for external leakage weekly.
• Solenoid Valve 4v210-08: Test operation weekly. Clean the coil and core if stuck, or replace if burned out.
Electrical Systems
• HARTING Connectors: Inspect pins for corrosion or bending every 6 months. Apply dielectric grease to terminals for enhanced corrosion protection.
• ABB ACS510 Drive: Clean internal heat sinks quarterly. Verify parameter settings after any power interruption.
Sealing Components
• VITON/Standard O-Rings: Inspect for signs of extrusion or hardening during routine disassembly. Replace any seal showing degradation, even if not leaking.

On-Site Fault Repair Cases
Here are three real-world scenarios demonstrating how our parts resolve critical equipment failures.
Case 1: XJ-450 Compressor Air System Failure
Equipment: XJ-450 Drilling Rig Air Compressor
Fault: System air pressure drops rapidly, and the drill rig cannot maintain circulation.
Diagnosis: The 326-1644 Separator Filter element was completely saturated with oil, causing catastrophic air-oil separation failure and clogging the air line.
Repair: Replace the failed separator filter with a new 326-1644 unit, drain the contaminated oil from the reservoir, and flush the air line.
Result: Air system pressure returned to 1.0MPa. The compressor operated smoothly for 500+ hours without issue, eliminating the root cause of pressure loss.
Case 2: ZJ-20 Air Control Valve Malfunction
Equipment: ZJ-20 Drill Rig Air System
Fault: The drawworks fails to release the brake, causing a safety hazard during rig down.
Diagnosis: The Drill Valve 870902-00-0295 is stuck in the closed position due to dirt accumulation in the pilot air passage.
Repair: Remove the valve, clean the internal spool and ports using precision cleaning solvent, and reinstall. Test the valve operation.
Result: The air control system functions normally, releasing the brake smoothly. Downtime was limited to 1 hour.
Case 3: BOMCO Pump Piston Seal Failure
Equipment：BOMCO F1600 Triplex Mud Pump
Fault: Severe mud leakage observed at the piston rod, leading to loss of pump pressure and potential equipment seizure.
Diagnosis: The Piston Ring (17A3991X022) and O-Ring have failed due to abrasive wear from drilling fluid solids.
Repair: Replace the complete piston assembly, including the Piston Complete (20021508+80) and RING, PISTON (17A3991X022).
Result: Pump pressure is restored to 30MPa. The piston assembly is expected to last for the next 800-hour service interval, significantly reducing maintenance frequency.
FAQ (Frequently Asked Questions)
