Introduction to condenser tube cleaning system
Condenser tube cleaning system is a device used to scrub the inner wall of heat transfer tubes of central air-conditioner condenser by physical method.When the central air-conditioner is in refrigeration process,the temperature of the refrigerant rises,so it must be lowered.Cooling water system is the pipeline system used for cooling down the refrigerant and the condenser is the heat-exchange device for cooling refrigerant.Cooling water flows into the condenser through the inner wall of the heat transfer tubes and then flows out.The cooling refrigerant flows through the outer wall of the heat transfer tubes and the condenser exchanges heat by heat transfer tubes,and thus cool down the refrigerant.The cooling water flows into the condenser at a low temperature and flows out at a high temperature after absorbing heat.After operating for a long time,the heat transfer tubes may have incrustation,fouling and stain sediment on inner wall,which may affect the heat transfer efficiency.Small temperature drop of the refrigerant affects the refrigeration effect, increases the load on the host of the central air-conditioner and reduces the life of it,so the inner wall of the condenser heat transfer tubes must be regularly cleaned to extend the life of it.
On-line condenser cleaning system is a kind of equipment used for automatically cleaning the inner wall of the condenser heat transfer tubes on line by physical method when the refrigerating unit is under operation.By injecting and collecting the balls,the system can clean the heat transfer tubes periodically.This system can reduce usage amount of Water Treatment chemicals,enhance refrigerating efficiency of the unit and save electric energy.
Operating principle of condenser tube cleaning system
To start with the water pump of the condenser tube cleaning system and pump the balls from the ball injector to the water inlet of the condenser with water.The balls enter the end cover of the condenser along with the circulating cooling water and get into the copper tube of the condenser randomly.Driven by the circulating cooling water,the balls move inside the copper tube to scrub the inner wall of the tube.After leaving the tube,the balls get out of the end cover of the condenser with the circulating cooling water and enters the ball collector installed on the outlet pipeline of the condenser.Ball trap in the ball collector then traps the balls,with the water flowing away through the screen.Then the balls return to the ball injector,which means a whole cleaning process is finished.The cleaning frequency and times can be set via microcomputer control program,to realize automatic on-line cleaning.

Ball injector:The container used for storage,injecting and collecting balls.The installation position of the ball injector and the inlet and outlet connecting pipes shall ensure that the balls are even without blockage.
Ball collector:When the balls leave the condenser,they'll be caught by the ball collector.The chamber material is carbon steel or stainless steel,the max working pressure is 10-25 bar,the effective open area is greater than 3 times of that of the connecting pipe and the hydraulic resistance loss is less than 5 Kpa.The ball collecting screen shall be designed with good hydraulic characteristics to prevent the screen from vibrating under the impact of water flow.The design of the ball collecting screen shall ensure no blocking or slipping of balls.

Features of condenser tube cleaning system The host of condenser tube cleaning system integrates the water pump and ball injector,saving space and covering less area. 2. It's easy to operate.The cleaning can be finished by controlling the start and stop of the water pump by time,and the cleaning time,interval and frequency can be set.
3. The ball collector is equipped with a water flow switch.When the circulating cooling water stays still,the water pump of the cleaning device cannot rotate,which prevents the water pump from operating without water.
4. The ball collecting screen applies stainless steel screen with large mesh size,which only traps the balls and has low water resistance.
5. The balls only circulate in the pipeline and do not go through water pump,which can prevent the pump impellers from hitting the balls and extend the service life of the balls.
6. The operating cost is low and the sponge balls are the only consumables.
