■ Product Overview
The rubber ball cleaning device of condenser is a kind of elastic rubber ball which makes the wet diameter slightly larger than the inner diameter of the heat exchange tube of condenser pass through the steam exchange tube when the refrigeration unit is running. The heat exchange tube is cleaned periodically in real time through the injection and recovery of the elastic rubber ball. In this process, the rubber ball is used to scrub the inner wall of the heat exchange tube, and the inner wall of the heat exchange tube of the condenser is automatically cleaned online through physical methods, so as to clean the dirt and scale deposited on the inner wall of the water tube, avoid the growth of microorganisms, prevent corrosion, ensure the cleanness of the inner wall of the heat exchange tube, ensure the good heat exchange effect, and improve the heat efficiency of the unit.
■ Working principle
The suitable sponge rubber ball is selected, and the wet specific gravity is similar to that of water. Put the rubber ball into the ball loading chamber, and the quantity is 10% of the number of copper pipes in the water inlet chamber of the condenser. Then start the rubber ball pump, open the ball valves at both ends of the system, and the rubber ball will enter the condenser water chamber driven by the water flow with slightly higher inlet pressure of the circulating water. Because the rubber ball is a multi porous soft elastomer, under the effect of the pressure difference at the inlet of the circulating water, it will be squeezed through the cooling pipe, and the inner diameter of the cooling pipe will be wiped once, so that the dirt on the inner wall of the pipe will be brought out with the water flow, and the rubber ball will go through the outlet pipe with the circulating water Enter the ball collecting net, separate the rubber ball under the block of the ball collecting net plate, pump out the rubber ball and return to the ball loading chamber, so as to realize continuous and automatic cleaning of the condenser cooling pipe.
