How to clean the radiator gun of a water-cooled screw chiller

There is no doubt that the water-cooled screw chiller needs maintenance. There are many places to be cleaned and cleaned, including condensers, evaporators, water towers, water pumps, etc. The center of this article is neither the condenser nor the evaporator, but the radiator!

　　 The time to clean the heat dissipating gun is after the heat dissipation capacity of the heat dissipating water tower is reduced, or after high and low pressure often have problems, it is generally recommended to clean it once every 5-10 months. The method of cleaning the heat dissipating gun is not difficult, as detailed below.

　　 First of all, you need to prepare a special cleaning agent for the barrel, which can be called gun washing water.

　　We need to pour the detergent into the water inlet of the water tower. When a certain amount is poured, the water outlet of the water tower will automatically flow out the turbid detergent. When the gun washing water flows out from the water outlet of the water tower, once it becomes turbid, it also means that the cleaning is effective, just repeat it several times. Finally, rinse with clean water.

　　 Please note that after the cleaning agent for cleaning the radiator becomes turbid, please do not touch it, so as not to harm the toxic substances.

　　 In addition to finding that the cooling capacity of the water tower of the chiller is reduced, and the cooling capacity of the chiller needs to be cleaned up, it is also necessary to clean and clean the cooling barrel or the cooling net when the water quality deteriorates in a short time after the cooling water is replaced.

　　 The following are the cleaning instructions for the heat sink indicated on the okmarts.com water-cooled screw chiller manual:

　　 1. The chiller has been used for more than six months, and the high/low pressure switch often fails, or the cooling capacity is reduced. Please arrange for staff to clean the radiator. If repairs are performed according to the above instructions several times and the chiller failure alarm sounds long, then notify the factory to contact for repairs.

　　2. If the chiller is equipped with a pressure gauge, pay attention to whether the pressure is higher than 18 kg/cm². If it exceeds, clean the radiator or check whether the water pipe is closed.

　　3. Pressure is one aspect of consideration. As mentioned above, in the case of poor cooling such as changes in cooling capacity, high cooling water temperature, and high chilled water temperature, it is necessary to consider cleaning the heat dissipation barrel and replacing the heat dissipation net.

　　4. While cleaning the radiator cannon again, in the same way, it is necessary to ensure that the cleaning is completed in a short time, and the water tower should be inspected in all directions to avoid the problem of poor cooling caused by other non-radiation cannon barrels.
