The normal pitching amount is 7% -13% of the number of cooling pipes in a single process on one side of the condenser. Depending on the length of time required for the rubber ball to cycle once, the lower or upper limit or its approximate value is taken. The time for the rubber ball to cycle once is generally limited to 30 seconds. The replenishment cycle for rubber balls is 7 cumulative runs of the rubber ball cleaning system, which can also be adjusted according to the specific situation of our unit. According to the statistics of domestic ball usage, the replacement cycle for rubber balls is 60 cumulative runs of the rubber ball cleaning system. In addition, after soaking in water for a period of time, some rubber balls may swell too much, causing the diameter to exceed the standard. When supplementing and replacing rubber balls, they should be replaced in a timely manner to prevent the cooling pipe from being blocked.
