Manually, remove the caps at both ends of the condenser of the environmental test equipment, use a spiral wire brush to go deep into the tube and reciprocate the brush, and rinse with high-pressure wate.
Mechanical cleaning method, use a tube washer for descaling, and pay attention to the expansion and welding of the condenser heat exchange tube and the tube sheet during cleaning to prevent vibration and loosenin.
This method is suitable for condensers made of steel cooling tubes and cannot be used for steel tube condenser.
Chemical removal method, use hydrochloric acid or other cleaning solution to remove scal.
Environmental test equipment (SETH cold and heat shock box) water-cooled condenser cleaning steps: ①Put out the working fluid in the condenser; ②Close the inlet and outlet valves of the condenser, and remove the inlet and outlet pipes; ③Connect the inlet and outlet pipes of the condenser with acid Clean the system, start the cleaning pump, and the cycle time depends on the degree of scale removal; ④ After cleaning, use alkaline solution to clean and neutralize; ⑤ Rinse with clean water until the water is clear; There is no damage after cleanin.
Note: Anaerobic glue is used in the expansion and connection process of the heat exchange tube of the equipment, and it should be noted that the cleaning liquid used for cleaning cannot react chemically with i.
During the use of the tube condenser of the environmental test equipment, the connection between the tube and the tube sheet is prone to leakage, and the inner and outer surfaces of the tube may be rusted and small holes, or when the condenser is stopped, the ambient temperature is below 0 °.
, the heat exchange tube will also freeze and crac.
The following methods can be used to check the leakage part: extract the working fluid from the condenser of the environmental test equipment, and remove the covers at both ends of the condense.
Punch into the shell side, plug one end of the condenser with cork to exchange the heat exchange tube, and use soapy water to check the leak at the other en.
If the leaking pipe is relatively small, it can be blocked with a dead pipe or replaced with a new pip.
Leak detection and air tightness test are required after replacement
