Quick-change bolt assemblies adopt optimized locking structure, realizing rapid screen disassembly and assembly without auxiliary tools. Degasser impellers and pump bodies adopt precision casting process with smooth flow channel inner wall to reduce medium scouring loss. Damping accessories adopt high-elastic composite rubber formula, with uniform stress and long service life. Instrument components adopt industrial anti-vibration and anti-interference design, adapting to complex electromagnetic environments on drilling sites.

3.2 Applicable Working Scenarios

This series of spare parts is widely applicable to onshore conventional oil and gas drilling, deep well high-pressure drilling and offshore platform drilling projects. It can stably operate in working environments with temperature ranging from -35℃ to 65℃, adapting to high-humidity, dust-intensive and mud-corrosive working conditions. It fully meets the 24-hour continuous cyclic operation demands of Derek FLC503 solids control systems and vacuum degasser equipment, serving as standard supporting accessories for drilling fluid purification system maintenance.

4. Engineer Practical Maintenance Suggestions

Based on years of on-site drilling equipment maintenance experience, standardized maintenance operations can effectively extend equipment service life: Replace shaker damping rubber and damping strips every 800 working hours to avoid vibration resonance caused by aging deformation; inspect jet pump and venturi pump flow channels monthly to remove accumulated solid impurities and prevent flow blockage; calibrate Murphy pressure and temperature instruments every 300 hours to ensure monitoring accuracy; check circuit switches, fuses and cable assembly tightness before each shift operation. Avoid over-tightening screen fixing bolts during installation to prevent screen deformation; replace sealing kits in pairs to ensure uniform sealing stress; clean instrument probe surfaces regularly to avoid data distortion caused by mud coverage.
