              I.Function

              Rubber ball cleaning device is the best equipment for effective cleaning of condenser cooling pipe in the operation of steam turbine generator set. The performance of the device directly affects the cleanliness and heat transfer efficiency of the condenser. The device operates online and can be operated manually and automatically. It can keep the condenser transfer pipe (copper pipe or stainless steel pipe) in a clean state all the time, prolong the service life of cooling pipe and reduce labor intensity. It is an indispensable device to improve the economic benefit of power plant and ensure the safe operation of condenser.

              Ⅱ.Components of rubber ball cleaning device:

              The utility model is composed of ball receiving net, ball loading chamber, rubber ball pump, distributor, valves, pipelines and an electrical control cabinet.In order to ensure the reliable operation of rubber ball cleaning device and prevent a large amount of impurities in circulating water from blocking condenser heat exchanger pipe (copper or stainless steel pipe), a secondary filter should be installed on the inlet pipe of circulating water, which can remove impurities larger than 7 mm in circulating water.

              II.Advantages 

              The rubber ball device manufactured by our factory is an updated product of other rubber ball cleaning devices. The main components of this device are ball collecting net and secondary filter net. It has the following characteristics:

              The design structure is novel and reasonable, the operation is convenient, the rubber ball recovery rate (≥95%), the secondary filter has strong filtering ability, and the water resistance is less than 350mmH2O.

              I.Function

              Receiving ball net is the key equipment in rubber ball cleaning system. It is installed on the outlet pipe of condenser. The circulating water carrying sponge ball passes through the condenser pipe bundle. After being blocked by receiving ball net plate, it is transported to ball-loading chamber, distributor and other valves by rubber ball pump into the inlet pipe of circulating water and then into the condenser for recycling use. Its function is to separate rubber ball from circulating cooling water and the ball cant be jammed and leaked. The receiving net produced by our factory consists of three types: SD (single mesh type), SF ("A" shunt type) and SLD (funnel type).

              II. Working principle:

              The diameter of the wet ball is slightly larger than that of the cooling pipe (about 1-2 mm), and the wet specific gravity of the ball is similar to that of water. The rubber balls are put into the ball-loading chamber from its hand hole, and the quantity is about 10% of the copper pipe in the condenser inlet chamber. Then start the rubber ball pump and open the ball valves at both ends of the system. The rubber ball is driven into the condenser water chamber by a flow slightly higher than the inlet pressure of the circulating water.

              Because the rubber ball is a flexible elastomer with many micro-holes, under the action of pressure difference between the inlet and outlet of circulating water, it is extruded through the cooling pipe and wiped the inner diameter of the cooling pipe once, so that the fouling on the inner wall of the pipe is brought out with the water flow, and the rubber ball enters the ball receiving net with the circulating water passing through the outlet pipe. The rubber ball is separated by the blocking of the ball-collecting mesh plate and pumped out by pump and returned to the ball-loading chamber, so that the condenser cooling pipe can be continuously and automatically cleaned by recycling.

              Structural characteristics

              SD (single mesh) ball-collecting net is suitable for DN400-700 mm pipe diameter system. It consists of mesh board, operation shaft, guide wing, shell, operation mechanism (electric actuator), etc. The reticulated plate is made of stainless steel bars and can be rotated. When the reticulated plate is on the outer shell wall, it is in the receiving position.Rotate a certain angle beyond the center line of the receiving net to reach the backwashing position about 10 degrees.

              Working Principle

              Receiving position: When the system is running, the net plate is in the receiving position. At this time, the net plate is close to the inner wall of the shell. The rubber ball is blocked by the net plate on one side. Through the lead-out pipe, the rubber ball is carried by a small stream of water and be sucked the rubber ball conveyor pump. Thus, the rubber ball is sent back to the loading chamber for recycling. Backflush position: When the pressure difference between the front and back of the mesh plate reaches a certain value, the operation of the mesh plate to the backwash position (after receiving the ball), then the accumulated debris on the mesh plate, it will be washed and carried away by the cooling water.

              IV. SF ball receiving Net

              Structure

              SF type ball receiving net is used in DN800-DN2200 system of circulating water pipe. It is composed of two grid plates, two operation shafts, two guide plates, two outlets, housing, transmission mechanism,Grid plate, etc. The two mesh boards are made of stainless steel bars, which can be turned over. The "A" type arrangement is used. When the reticulated plate is "A" shape, and the edge is attached to the inner wall of the shell it is in the receptacle position; it is in backwashing position when the two mesh boards are turned to both sides at a certain angle.

              Working principle

              Receiving position: When the system runs, the net plate is in the receiving position. At this time, the edges of the two mesh plates are attached to the inner side of the cylinder wall respectively. The rubber ball is gathered on both sides of the receiving net because of the blocking of the net plate. The rubber ball is carried by the water flow through the outlet of the rubber ball. After collecting, it is sucked into the rubber ball conveying pump and sent back to the cleaning system for recycling.
