Condenser Tube Cleaning System

Condenser Tube Cleaning System 1.Operation principle:apply proper sponge rubber ball, wet diameter of the ball shall be 1 to 2 mm more than cooling water tube, wet density of the ball is from 1.00 to 1.15g/cm3. Charge balls into system from ball collector handhole, balls will be sent into inlet of the cooling water by ball pump and flow into condenser water room with the water, diffused balls will distribute equably and get into cooling tube, get through them under being pressed and take away the dirty of the tube inner wall, the balls will spread around the water, ball strainer located on the outlet section of the condenser will callback the spread balls, ball pump will draw out them and send them into ball collector, cycle like this. One cycling cleaning time from 20 to 40 seconds as different route, each ball could cleaning from 45 to 90 or from 90 to 180 cooling tubes after cleaning system operating from 30 to 60 minutes, therefore, charge balls as 10 percent of tubes, which will clean all the tubes four times above. Which consists of: ball strainer, ball collector, ball pump, sponge rubber ball, valves, control cabinet etc. equipment. 2.The ball strainer is a key part of the condenser tube cleaning system, its function is to segregate the balls from cooling water, and ensure no balls leakage or blocked. Ball strainer be installed on the outlet section of the cooling water, the balls will be callback when the water contain balls from condenser get through the balls strainer and educed from ball strainer by discharging pipe. The screen of the strainer could be rotary, screen will be in “recovery” under ball cycling, screen will be in “back washing” under no balls charging, and at this time the dirty with the screen will be swept by the water and decrease the screen water resistance. Turning orientation of the screen will be ensured by electric actuator (minitype ball strainer is manual operation). 2.The ball collector is a device which is used to charge, collect, change and to observe operation of the condenser tube cleaning system. Different type as for volume balls –contained, there are electric and manual operation as per use’s requirements. Balls could cycle free and continuously in the system when on-off valve which control operation status of ball collector in “charging” position, when on-off valve in “recovery” position, balls will be blocked in the ball collector, however the cooling water could get through, and all the balls charged in cycling could be collected in the ball collector. 3.The ball recirculating pump is a motive source in the condenser tube cleaning system. The water balls serried from ball strainer get through the ball pump and heighten the press head then be sent into the cooling water pipe. This pump is a special expedite centrifugal pump with specialties of balls unblocked, balls uncrushed and light abrasion etc. Select ball pump with different parameters and specification as per operating conditions. Select low flow ball pump for minitype condenser and heat exchanger system in order to reduce hot water refluence. Select high lift ball pump for long feeding pipe and more resistance loss in order to ensure the normal recirculating.
