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 ZJ50L gear pumps (111.26.123.02 BBC-B100Y), Boiler WNS2-1.25-5Y check valves, and DC motors YZ08A 800kW every 65 operating hours; inspect sealing parts (O-ring B109S10, Dust Ring J-50) and filters (Oil Filter ZJ50LDBTF-160×180L) for wear or clogging, and replace them in time to avoid system failure.

• Cleaning & Lubrication: Keep gear pumps, gear hubs (515913), and thrust bearings (6839818) clean; apply appropriate lubricating oil to reduce friction and prevent rust and wear. For hydraulic valves and solenoid valves, ensure the hydraulic oil is clean and replace it regularly to avoid component damage.

• 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 (SPX9504) and boiler 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 hex socket head cap screws DQ70 4201121160 M6×70 properly to prevent thread damage). For drilling rig components, boiler parts, and industrial equipment, follow OEM installation guidelines to ensure compatibility and safety.

• Filter & Seal Maintenance: Regularly replace air filters (RS-3510) and oil filter elements; check boiler safety valves (A48Y16C) for proper operation; inspect sealing strips (5P5678) 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: Gear Pump Failure in ZJ50L Drilling Rig

A customer’s ZJ50L drilling rig experienced hydraulic system pressure loss due to a faulty gear pump (111.26.123.02 BBC-B100Y), causing hydraulic components to malfunction and drilling operations to stop. We supplied the ZJ50L Gear Pump 111.26.123.02 BBC-B100Y, which is fully compatible with the rig. After replacement, the hydraulic pressure returned to normal, all components operated smoothly, and the rig resumed drilling, reducing downtime by 85%.

Case 2: Check Valve Leakage in Boiler WNS2-1.25-5Y

An industrial plant’s WNS2-1.25-5Y boiler had fluid backflow and pressure instability due to a leaking check valve (DN25 PN25P), risking boiler safety and reducing efficiency. We provided the Boiler WNS2-1.25-5Y Check Valve DN25 PN25P, which fits perfectly with the boiler. After replacement, the backflow was eliminated, boiler pressure stabilized, and the boiler operated safely for 900 hours, improving energy efficiency by 25%.

Case 3: Solenoid Valve Malfunction in Ingersoll Rand System

A drilling team’s Ingersoll Rand system had air lock issues due to a faulty bleed solenoid valve (22516025), causing pneumatic component failure. We supplied the Ingersoll Rand Bleed Solenoid Valve 22516025, which is compatible with the system. After replacement, the air lock was resolved, the pneumatic system operated normally, and drilling operations resumed without further interruptions, reducing maintenance time by 70%.
