 PSZ75B-70D-B-00 Disc Brake Actuator: Features a compact, lightweight design for easy installation on drilling rigs, with a dual-cylinder structure that ensures uniform braking force (up to 1200N·m); the sealed housing protects internal components from dust and moisture, ensuring reliable operation in harsh environments.

Applicable Working Conditions

All our products undergo rigorous environmental and performance testing to ensure reliable operation in the harsh, complex working conditions of industrial and aviation-related sites:

 Temperature Range: -50°C to 220°C (for high-temperature grease P-1587 and high-temperature resistant seals), suitable for cold northern drilling sites, high-temperature compressor rooms, and aviation ground support in extreme climates.

 Pressure Range: 0-60MPa (for drilling rig components, piston assemblies, and pressure transmitters), meeting the high-pressure requirements of oil drilling rigs, hydraulic systems, and pumps.

 Environmental Resistance: IP65-IP67 protection rating (for aviation sockets, pressure transmitters, and air filters), dustproof, waterproof, and anti-vibration (≤ 15g), suitable for outdoor oil drilling rigs, construction sites, and aviation ground support areas.

 Corrosion Resistance: 316L stainless steel, fluororubber, and anti-corrosion coatings are used to resist acid, alkali, oil, and saltwater corrosion, making our parts suitable for offshore oil platforms, chemical plants, and coastal aviation facilities.

 Load Capacity: ZJ70L turntable components can withstand load pressures up to 40MPa, disc brake actuators provide braking force up to 1200N·m, and aviation sockets can carry 25A current—meeting the high-load and high-performance requirements of industrial and aviation equipment.

Maintenance & Care Recommendations

Proper maintenance is essential to extend the service life of our products, reduce maintenance costs, and ensure consistent performance. Below are practical, easy-to-follow guidelines for key products, designed for on-site technicians:

 25YZ-3P+E-25A Aviation Socket: Inspect the socket’s contact pins and locking mechanism every 1 month to ensure they are clean and tight; clean the pins with a dry cloth to remove dust and debris; avoid pulling the cable directly to prevent damage to the socket connection.

 B99 Oil Filter: Replace the filter every 2000 working hours (or 6 months), whichever comes first; check the filter housing for leaks after replacement; ensure the bypass valve is functioning properly to prevent oil starvation in case of clogging.

 ZJ Series Drilling Rig Components: Lubricate the ZJ70L turntable roller square bushing with high-temperature grease P-1587 every 3 months; replace the ZJ50L FBX-400×10 oil return filter element every 1500 working hours; inspect ZJ70/4500DZ seals for wear or leakage monthly and replace as needed.

 Compressor Filter Elements (20514654, 250025-526): Replace the air filter element every 3 months (or when pressure difference exceeds 0.05MPa); replace the oil filter element every 12 months; clean the filter housing regularly to remove accumulated dust and debris.

 YPQ-25B Pneumatic Pressure Transmitter: Calibrate the transmitter every 6 months using a standard pressure gauge to ensure accuracy (error ≤ ±0.5% FS); check the wiring and connection points for corrosion or looseness monthly; protect the transmitter from direct impact to avoid sensor damage.

Note: All maintenance operations should be performed by trained professional technicians in accordance with the equipment’s operation manual. Always use genuine replacement parts to ensure compatibility, performance, and safety—using non-genuine parts may cause equipment damage or safety hazards.

On-Site Fault Maintenance Cases

Below are 3 real on-site fault cases, featuring practical solutions to help you quickly resolve common issues with our products, minimizing downtime and reducing maintenance costs:

Case 1: 25YZ-3P+E-25A Aviation Socket Poor Contact

Fault Phenomenon: Aviation ground support equipment experienced intermittent power loss, with the 25YZ-3P+E-25A socket showing loose connection. Inspection: The socket’s contact pins were contaminated with dust and oxidation, and the locking mechanism was worn. Solution: Clean the contact pins with a specialized cleaning agent, polish the oxidation layer gently, and replace the worn locking mechanism. Reconnect the socket and test. Result: The connection became stable, and the equipment operated without intermittent power loss for 10 months.

Case 2: B99 Oil Filter Clogging Causing Equipment Overheating

Fault Phenomenon: A heavy-duty engine equipped with B99 oil filter (equivalent to CAT 1R0716) overheated, with oil pressure dropping significantly. Inspection: The B99 filter was severely clogged with metal particles and sludge, and the bypass valve failed to open. Solution: Replace the B99 oil filter with a new one, flush the lubrication system to remove impurities, and check the bypass valve for functionality. Result: Oil pressure returned to normal, engine overheating was resolved, and the engine operated smoothly.

Case 3: ZJ50L FBX-400×10 Oil Return Filter Element Blockage

Fault Phenomenon: A ZJ50L drilling rig hydraulic system experienced pressure loss and slow operation. Inspection: The FBX-400×10 oil return filter element was clogged with impurities, restricting oil flow. Solution: Replace the filter element with a new ZJ50L FBX-400×10, clean the filter housing, and check the hydraulic oil for contamination (replace oil if necessary). Result: Hydraulic system pressure was restored, and the drilling rig operated at normal speed.
