Maintenance & Care Suggestions

Proper maintenance can extend the service life of mechanical parts and reduce replacement costs. Here are practical, easy-to-follow suggestions:

• Regular Inspection: Check pressure gauges, fuel injectors, and sealing parts every 80-100 operating hours; replace worn or damaged parts (such as O-rings 5303100950 and friction discs W14-07-901) in time to avoid equipment failure.

• Cleaning & Lubrication: Keep diamond core bits, turntable friction wheels, and bearings clean; apply appropriate lubricating oil (matching the equipment manual) to reduce friction and prevent rust.

• Storage Requirements: Store parts in a dry, ventilated, and dust-free warehouse; avoid direct sunlight and contact with corrosive substances (especially high-temperature O-rings and gaskets AH0801010415).

• Installation Notes: Ensure parts are installed correctly according to the equipment manual; avoid forced installation (e.g., aligning hydraulic lines DQ70BS 50H0465 M22280 properly to prevent pipeline stress).

• Filter Maintenance: Regularly replace filter elements (e.g., 8159975, P556915, FS1000) to ensure the cleanliness of hydraulic oil and engine fuel, preventing component wear caused by impurities.

On-Site Fault Maintenance Cases

Here are 3 real on-site maintenance cases, showing how our parts solve practical problems for customers and reduce downtime:

Case 1: Pressure Gauge Failure in ZJ45 Drilling Rig Hydraulic System

A customer’s ZJ45 drilling rig experienced inaccurate pressure readings from a non-original pressure gauge, leading to improper hydraulic system operation and frequent component wear. We supplied our Pressure Gauge M14x15 0-16Mpa (P/N-Y-60Z), which features high precision and rugged design. After replacement, the gauge provided accurate pressure data, allowing the hydraulic system to operate normally, and reducing component wear by 60%.

Case 2: Fuel Injector Malfunction in Industrial Boiler

An industrial plant’s WNS2-1.25-Y boiler had a faulty fuel injector (non-original), causing uneven fuel combustion, high fuel consumption, and boiler inefficiency. We provided the Fuel Injector Assembly 8N7005, which is fully compatible with the boiler. After installation, the boiler’s fuel combustion became stable, fuel consumption decreased by 15%, and operational efficiency was restored to normal.

Case 3: O-Ring Leakage in ZJ70 Drilling Rig Hydraulic System

A ZJ70 drilling rig’s hydraulic system had serious oil leakage due to a worn O-ring (non-high-temperature resistant). We supplied the High-Temperature O-Ring DQ70BSC (5303100950 10×2.65), which is designed to withstand high temperatures and pressures. After replacement, the leakage problem was completely solved, and the hydraulic system operated continuously for 400 hours without failure.
