Field Fault Maintenance Case
Case 1: Manifold Control Box JYK-70D Failure Caused by Salt Spray Corrosion - On an offshore oil drilling platform, the JYK-70D chock manifold control box failed suddenly, leading to the shutdown of the fluid control system. Inspection found that the box body and internal connectors were severely corroded by salt spray, resulting in poor contact of the connectors and signal transmission interruption. Root cause: The platform's marine environment had high salt spray concentration, and the box body's anti-corrosion coating was partially damaged due to long-term use, failing to effectively resist corrosion. Solution: Replaced the corroded control box with a new JYK-70D model, and enhanced the anti-corrosion treatment of the box body surface (adding a layer of anti-salt spray coating). Installed a protective cover to reduce direct salt spray erosion. After maintenance, the control box operated stably for 18 months without corrosion failure, complying with the offshore equipment operation requirements.
Case 2: Hydraulic Pressure Sensor YCQ-70 Measurement Inaccuracy - In a hydraulic press workshop, the YCQ-70 vibration-proof pressure sensor displayed obvious measurement deviation, leading to unstable pressure control of the hydraulic press. Inspection found that the sensing element of the sensor was contaminated by metal particles in the hydraulic oil, and the sealing ring was aging and leaking. Root cause: The hydraulic system's filter element was not replaced in time, resulting in excessive metal particles in the oil, and the sealing ring exceeded the service life without replacement. Solution: Replaced the YCQ-70 sensor with a new one, replaced the hydraulic system's filter element and all aging sealing rings, and filtered the hydraulic oil thoroughly. Established a regular maintenance system (replacing the filter element every 500 operating hours, checking the sensor sealing ring every 8 months). After improvement, the pressure measurement accuracy was restored to the rated level (±0.5% FS), and the hydraulic press operated stably.
