| description | The utility model discloses an on-line pneumatic diaphragm replacement system of a coal gasification coal slurry delivery pump. The high-pressure coal slurry pump comprises a high-pressure coal slurrypump body, the high-pressure coal slurry pump body is composed of a power end, a hydraulic end and a hydraulic control system. Wherein the hydraulic end is connected with the power end and the hydraulic control system, an isolation device is arranged between the hydraulic end and the hydraulic control system, and the isolation device isolates pressure oil conveyed to the hydraulic end by the hydraulic control system. An isolation device is additionally arranged on an oil supplementing and discharging pipeline of each piston oil cylinder of the high-pressure coal slurry pump; according to theprocess method, the hydraulic end and the oil way pipeline are isolated, the interlocking protection mode is changed, finally, the pneumatic diaphragm of the oil supplementing and discharging diaphragm valve is completely repl |
