The cause of the plate cylinder cooler temperature is too high and the elimination method ( 1) Cause (1) plate cooler in the cooling water supply. Suction, exhaust valve leakage, (2) plate cooler or stage pressure ratio is too large. (3) use made of filled ptfe piston ring and piston ring gap is too small, of the causes of cylinder lens hair phenomenon. ( 2) Methods (1) check dredge plate cooler cooling water piping, removal of leaks. Increasing cooling water pressure of water supply and water supply. (2) maintenance plate cooler air valve, to eliminate leakage Chun. Adjust the cylinder clearance volume, in order to obtain reasonable level pressure ratio, thus reduce the temperature of the cylinder. (3) the appropriate increase filled ptfe bearing ring or piston ring expansion gap, generally take: o plate cooler piston ring expansion gap = ( 0. 02-0025) D plate cooler bearing ring expansion gap = ( 0. 025 - ~ 003). In the type D D for piston ring or supporting ring outer diameter ( mm) 。
