Causes and treatment methods of wax formation in water coolers.
Thread Content
The main reason for wax formation is； 1] Ordinary driving and parking 2] The operating temperature is too low, etc. ； 1】Online wax removal ； Cut off the fresh air, turn on the self-circulation, close the cooling water valve of the water cooler, introduce steam or condensate into the water cooler for blowing, and open the bottom discharge valve of the alcohol fraction. 2] Parking to remove wax ； During the parking process, directly pass steam or condensate into the water cooler for blowing, and then use the alcohol separation bottom drain valve.
Haha, the reason for the analysis is very thorough, but it is not suitable for online processing. Just close the circulating water valve, because the temperature of the circulating gas is quite high, and it is still 80 or 90 degrees after passing through the intermediate heat exchanger. Part of it can be removed, but the time cannot be long. If the reciprocating compressor cannot stand it, of course, this cannot be completely eliminated. The only way to completely remove it is to stop the steam blowing.
Nowadays, most of them use online wax removal, but this is only a temporary method. Generally, they wait until the car is stopped for overhaul every year to remove the wax cleanly and thoroughly.
The shutdown time for processing and maintenance will be longer. After online processing, if it can meet the production load needs, it will be temporarily processed, and it will be completely removed during major maintenance.
We generally do online processing here, and perform thorough processing during overhaul every year.
Online wax removal is only temporary. If the time is short, there will be no effect. After a long time, the equipment cannot stand it. However, if the wax formation is not serious, online wax removal once a month will be effective. If wax formation is severe. Steam blowing during parking will not remove the roots. It is better to cut the elbow and use a high-pressure water gun to weld the elbow and apply pressure. It can be opened with 10mpa and it will be very clean.
Wax removal also depends on the specific situation. If you need to stop the car for processing, we will stop the car to remove the wax as the poster said. However, if the situation is not serious without stopping, you can remove the wax online, but the time cannot be too long.
Anyone who cooks wax online please share your experience.~~~
