(1) When the compressor is installed, pay attention to the clearance of the cylinder legs and the stress of the bolt to make it well supported.
(2) Regularly test the clearance of the compressor cylinder (generally, the clearance coefficient of the low-pressure cylinder of large and medium-sized compressors is less than 8%, and the clearance coefficient of the high-pressure cylinder can reach about 12%), regularly test the position of the piston at the upper and lower dead center, and timely adjust to ensure its normal operation.
(3) Check the connection of crankshaft shingle, nut, connecting rod bolt, crosshead bolt, and shaft diameter, exhaust valve plate, and spring force of valve spring in crankcase regularly.
(4) Detected due to large flywheel imbalance caused by balance iron, on the flywheel into action balance correction.
