High-efficiency Differential Rotation Screw Press

Visual inspection of bowl interior for sludge deposits, disc wear, and separation disc integrity; check for discoloration, scaling, or corrosion on disc stacks

Verify oil bath and splash lubrication levels in bearing housings; inspect for dark or contaminated lubrication oil; check bearing temperature during operation (should not exceed 70°C); confirm oil seals prevent leakage

Check sludge discharge interval timer calibration (0-720 minute range); verify pilot valve mechanism for partial/total discharge capability; inspect discharge piping for blockages; monitor discharge pressure and flow

Monitor motor vibration and noise during operation; verify rotation speed accuracy; check electrical connections and control panel indicator lights; confirm motor power output meets specification; inspect coupling alignment

Verify feed pump discharge pressure (standard range 3-5 bar); check for cavitation noise; inspect pump impeller wear; monitor inlet pressure; verify pressure relief valve function; check piping for leaks
