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 ZJ70D flanged elbows, ZJ50L hydraulic pumps, and Boiler WNS2-1.25-Y indicator lights every 65 operating hours; inspect sealing parts (Sealing Ring BK-SR-2) and filters (AIR FILTER PA2554) for wear, clogging, or leakage, and replace them in time to avoid system failure.

• Cleaning & Lubrication: Keep hydraulic pumps (ZJ50L 1.15.01.02), cardan shafts (W60.5×735), and bearings (Main Bearing AH160101010800) clean; apply appropriate lubricating oil to reduce friction and prevent rust and wear. For filters, clean or replace filter elements regularly to maintain filtration efficiency.

• 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 boiler parts). For high-pressure valves, hydraulic pumps, and explosion-proof equipment (YHB25), 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 one-way pins P2000693AA properly to prevent damage). For drilling rig components, boiler parts, and generator parts, follow OEM installation guidelines to ensure compatibility and safety.

• Electrical & Instrumentation Maintenance: Regularly check explosion-proof electric heads (YHB25) and control boards (SK-2Z16 3R03M-DCPU) for proper operation; inspect indicator lights (MAN TUNG) and cables for loose connections; clean electrical components to prevent dust accumulation and short circuits.

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: Flanged Elbow Leakage in ZJ70D Drilling Rig

A customer’s ZJ70D drilling rig experienced drilling fluid leakage due to a worn flanged elbow (4 1/16”x15M FLGQ103x105-90), causing operational delays. We supplied the ZJ70D Drill Rig Elbow Flanged, which is fully compatible with the rig. After replacement and pressure testing, the pipeline leakage was completely resolved, the drilling fluid system operated stably, and the rig resumed drilling operations, reducing downtime by 85%.

Case 2: Hydraulic Pump Failure in ZJ50L Drilling Rig

A drilling team’s ZJ50L drilling rig had hydraulic system failure due to a faulty hydraulic pump (1.15.01.02), causing winch and brake malfunctions. We provided the ZJ50L Hydraulic Pump 1.15.01.02, which fits perfectly with the rig’s hydraulic system. After replacement and system debugging, the hydraulic pressure returned to normal, all hydraulic components operated smoothly, and maintenance costs were reduced by 70% compared to replacing the entire hydraulic unit.

Case 3: Indicator Light Malfunction in Boiler WNS2-1.25-Y

An industrial plant’s WNS2-1.25-Y boiler had operator confusion due to a faulty indicator light (MAN TUNG), leading to inefficient monitoring and potential safety risks. We supplied the Boiler WNS2-1.25-Y Indicator Light MAN TUNG, which is compatible with the boiler’s control system. After replacement, the indicator light operated normally, providing clear status feedback, and boiler operation safety was significantly improved.
