Maintenance & Care Recommendations

Proper maintenance can significantly extend the service life of our products, reduce maintenance costs, and ensure stable performance. Below are practical maintenance guidelines for key products:

• Connectors (MS3102A 14S-6S): Clean the contact pins with a dry cloth every 3 months to remove dust and oil; check the locking mechanism regularly to ensure it is tight and free of looseness; avoid pulling the cable directly to prevent damage to the connector.

• Pressure Transmitter (CS-PT200): Calibrate the sensor every 6 months using a standard pressure gauge to ensure accuracy (error ≤ ±0.5% FS); clean the diaphragm regularly to prevent blockage by dirt; check the wiring for loose connections and corrosion.

• Brake Devices: Inspect the brake shoe wear every 1000 working hours; replace the brake shoe when the wear thickness exceeds 3mm; add lubricating oil (ISO VG 46) to the bearing bush every 3 months; check the brake hydraulic system for oil leakage and replenish hydraulic oil in a timely manner.

• Seals: Replace seals every 12-18 months (or when leakage is detected); ensure the sealing surface is clean and free of scratches before installation; avoid using sharp tools to install seals to prevent damage.

• Gear Pumps & Filters: Replace the oil filter cartridge (SPX-86×25, TF-400X80FS) every 2000 working hours; check the gear pump oil level regularly and replenish hydraulic oil (ISO VG 32-68) as needed; clean the filter screen to prevent clogging.

On-Site Fault Maintenance Cases

Below are 3 real on-site fault cases, providing practical solutions to help you quickly resolve common issues with our products:

Case 1: MS3102A 14S-6S Connector Signal Interruption

Fault Phenomenon: During the operation of a ZJ30 oil drilling rig, the control system signal is intermittent, causing the rig to shut down occasionally. Inspection: After checking, the Amphenol female connector MS3102A 14S-6S was found to have loose contact pins and dust accumulation in the connector cavity. Solution: Disconnect the connector, clean the contact pins and cavity with a dry cloth and compressed air, reinsert the contact pins firmly, and lock the bayonet mechanism. Result: The signal transmission became stable, and the equipment resumed normal operation; no further interruptions occurred within 6 months.

Case 2: CS-PT200 Pressure Transmitter Inaccurate Measurement

Fault Phenomenon: A Boiler EO-150 pressure display was inaccurate, with a deviation of more than 2 bar from the actual pressure, affecting boiler operation safety. Inspection: The CS-PT200 pressure transmitter diaphragm was found to be contaminated with scale, and the sensor was not calibrated for more than 1 year. Solution: Disassemble the transmitter, clean the diaphragm with a neutral cleaning agent, calibrate the sensor using a standard pressure gauge, and reinstall it. Result: The measurement accuracy was restored to ±0.5% FS, and the boiler pressure monitoring returned to normal.

Case 3: ZJ-30 Auxiliary Brake WCB324 Failure

Fault Phenomenon: The ZJ-30 oil drilling rig auxiliary brake WCB324 failed to brake, and the brake pedal was loose.Inspection: The brake hydraulic oil was insufficient, and the brake shoe was severely worn (wear thickness 4mm). Solution: Replenish the hydraulic oil (ISO VG 46) to the standard level, replace the brake shoe with a new LT1070*200T brake shoe assembly, and adjust the brake clearance. Result: The brake function was restored, and the braking force met the equipment requirements, ensuring safe operation of the drilling rig.
