Hydraulic valves feature precision lapped internal structures for sensitive pressure regulation. Sealing parts adopt high-performance composite polymer materials with excellent compression recovery and corrosion resistance. Electrical sensor components are equipped with anti-vibration and anti-interference encapsulation layers. Bearing and transmission parts adopt high-strength alloy forging and precision grinding processes to reduce operating wear and deformation.

This series of spare parts adapts to onshore deep-well drilling, offshore platform directional drilling and high-pressure workover operation scenarios, matching the 275-ton full-load working parameters of Canrig 4017AC-122 and 6027AC-939 top drive systems. It stably operates in ambient temperatures ranging from -30℃ to 65℃, resisting offshore salt fog corrosion, desert dust accumulation and high-pressure medium erosion, fully supporting 24-hour non-stop continuous cyclic drilling tasks.
3.2 Engineer Practical Maintenance Suggestions
Summarized from years of frontline oilfield overhaul experience, standardized maintenance effectively extends component service life and reduces unplanned downtime. Replace hydraulic pressure regulating valves every 1900 working hours to avoid pressure regulation deviation. Calibrate encoders and proximity sensors every 500 working hours to guarantee signal accuracy. Renew all sealing and O-ring components every 2800 working hours to prevent micro-leakage. Inspect bearing clearance and locking fastener tightness quarterly. Avoid mixed installation of non-standard accessories to prevent system transmission and hydraulic matching errors.
