Maintenance & Care Suggestions

Proper maintenance and care can effectively extend the service life of products, reduce equipment failure rates, and ensure the stable operation of oilfield equipment. The following are targeted maintenance suggestions for different product categories, designed to help users maximize the service life of parts and reduce operational costs:

Valves & Hydraulic Components

• Regularly check valves and hydraulic hoses for leakage, corrosion, and blockage; it is recommended to inspect every 350 working hours. Clean the valve core and valve seat in time, and replace worn seals (such as OO-ring 6F4718) immediately to avoid hydraulic system failure.

• Lubricate the moving parts of valves and hand oil pumps every 200 working hours with high-temperature resistant lubricating grease (NLGI Grade 2) to ensure smooth operation and reduce wear.

• For brake components (such as PSZ75A-2-02-00 disc brake working pliers assembly), inspect the brake pads and brake discs every 400 working hours; replace worn brake pads and grind the brake disc surface if the wear exceeds 0.1mm.

Drilling Tools & Mechanical Parts

• Inspect PDC drill bits and Steel Tooth Roller Bits for wear and damage after each use; grind the bit surface or replace the bit if necessary to maintain drilling efficiency. Store drill bits in a protective case to avoid collision and damage.

• Regularly check shafts, gears, and bushings for wear and deformation; replace them in time if the wear exceeds 0.08mm. Add lubricating grease to rotating parts every 250 working hours to reduce friction.

• Clean the rope hook T410-004 and Tong pulley assembly AA4501230300 every 500 working hours to remove mud and impurities, ensuring safe hoisting.

Electrical Components & Filters

• Clean air filters and diesel filters regularly; replace the air filter element 4N0015 every 300 working hours and the diesel filter 5I7951 every 500 working hours to ensure filtration effect.

• Check electrical components (such as potentiometers, pressure controllers, and cables) every 600 working hours; test their performance and replace damaged components in time to avoid electrical system failure.

• Store electrical components in a dry, dust-free environment, avoiding moisture and corrosion. Clean the surface of explosion-proof components regularly to ensure explosion-proof performance.

Seals & Fasteners

• Replace seals (such as sealing ring AZ502101-020218, Dust ring P1100301AA) every 800-1000 working hours, or immediately if oil leakage is found. Apply a thin layer of silicone grease to the seal surface before installation to reduce friction.

• Check fasteners (such as Hex head bolt with hole DQ70BS M10×30, Support bolt DQ70 9701060002) for looseness every 300 working hours; tighten them in time to avoid equipment damage caused by vibration.

On-Site Fault Maintenance Cases

The following are 3 real on-site fault maintenance cases, providing practical reference for users to quickly solve similar problems, reduce downtime, and improve operational efficiency. All cases use our products to achieve efficient fault resolution:

Case 1: ZJ-30C Drilling Rig Brake System Failure

Fault Phenomenon: The ZJ-30C drilling rig brake system failed to respond normally during operation, and the brake could not be engaged or disengaged smoothly, posing a safety hazard to hoisting operations.

Inspection & Analysis: After disassembly, it was found that the original three-position four-way manual reversing valve was worn and had internal leakage, resulting in unstable oil flow and failure to control the brake system. The original valve had a short service life and poor wear resistance, which failed after only 700 working hours.

Maintenance Solution: Replace the original valve with our Brake device ZJ-30C three-position four-way manual reversing valve 2-HA-2/4900350092. The new valve has a leakage rate of ≤0.08ml/min and a service life of more than 2000 working hours. After installation and debugging, the brake system responded normally, the brake engagement and disengagement were smooth, and the equipment operated stably for 1500 hours without failure.

Case 2: ZJ45 Drilling Rig Hydraulic System Impurity Blockage

Fault Phenomenon: The ZJ45 drilling rig hydraulic system had low pressure and slow movement of the hydraulic cylinder, affecting drilling efficiency. The system pressure continued to drop during operation.

Inspection & Analysis: After inspection, it was found that the discharge filter assembly was blocked by impurities, resulting in insufficient oil supply to the hydraulic system. The original filter assembly had a low dirt-holding capacity, which was blocked after only 250 working hours.

Maintenance Solution: Replace the filter assembly with our discharge filter assembly AH1001011900. The new filter has a dirt-holding capacity of 70g and a filtration precision of 10μm, which is 40% higher than the original. After replacement, the hydraulic system pressure returned to normal (35MPa), the hydraulic cylinder operation was smooth, and the drilling efficiency was restored.

Case 3: DQ70BSD Drilling Rig Inclinometer Data Transmission Failure

Fault Phenomenon: The inclinometer YST-48R of the DQ70BSD drilling rig failed to transmit data normally, and the hub controller could not receive hook load data, affecting the judgment of drilling conditions.

Inspection & Analysis: After inspection, it was found that the inclinometer cable (hub controller-hook load) 4910006 was worn and had poor contact, resulting in signal loss. The original cable had poor wear resistance and could not adapt to the frequent movement of the drilling rig.

Maintenance Solution: Replace the original cable with our Inclinometer YST-48R cable 4910006. The new cable has a wear-resistant outer sheath and a signal transmission accuracy of ≥99.8%. After replacement, the data transmission was normal, the hub controller could receive hook load data in real time, and the drilling operation was carried out smoothly.
