The invention relates to a condenser rubber ball cleaning multi-point centralized feeding system which comprises a condenser water chamber, a cooling water outlet pipeline, a cooling water inlet pipeline, a ball screen, a second isolation door, a rubber ball pump, a check valve and a trash-removal machine. The water inlet end of the condenser water chamber is connected with a plurality of pulse ball feeding valves; a plurality of pulse ball feeding valves are connected with a ball adding chamber by a rubber ball conveying pipe; the rubber ball conveying pipe is connected with the cooling water inlet pipeline by another pulse ball feeding valve; the ball adding chamber is connected with the circulating cooling water outlet pipeline by a hot water drainage pipe; the hot water drainage pipe is provided with a third isolation door and a hot water drainage valve; the lower part of the ball adding chamber is provided with a rubber ball discharge valve. The system can reduce the quantity of heated circulating cooling water which enters a water inlet pipeline of a circulating cooling water system again in the operating process of a rubber ball system, and improves a circulating cooling effect of a condenser; by oppositely and correspondingly operating opening or closing of the pulse ball feeding valves and the hot water drainage valve, a great number of rubber balls enter the circulating cooling water inlet pipeline and the condenser water chamber in a centralizing manner in short time so as to clean a heat exchange pipe of the condenser in a full-covering manner.
