Cooler For Transportation Vehicles Cleaning Coup Leak How To Do
Oct 30, 2017

How does the dirt in the plate Cooler for Transportation Vehicles happen and how will these dust adversely affect the plate cooler?

First of all, the normal cooling water will contain more abundant calcium, glass and acid acid and acid salt water and other substances, and contain these substances through the metal surface of the cooling water, and metal attack chemical reaction, and then the emergence of carbon Acid and the like. In addition, the oxygen in the cooling water will also erode the metal, and lead to the occurrence of rust.

Once the rust occurs, the heat exchanger will first react to the heat transfer effect, especially in the case of rust, and then can block the tube, so that the tool heat transfer performance completely. And if the continued use of the case, will lead to more and more power consumption, echo will increase the cost.

So always pay attention to the clean-up of the plate Cooler for Transportation Vehicles, so that both can extend the use of life tools, progressive utility can also waste power and time, reduce costs.

1, washed Xian

Before pickling, first on the Cooler for Transportation Vehicles to open the rinse, so that there is no internal heat exchanger mud, dirt and other impurities, which can improve the effect of pickling, but also reduce the amount of acid consumption of pickling. Wash the cleaning solution into the cleaning device and inject it into the heat exchanger.

2, pickling

Will be filled with acid solution heat exchanger static soak 2h. And then continuous dynamic cycle 3 ~ 4h. During which every 0.5h for positive and negative alternately cleaning. After pickling, if the acid pH is greater than 2, the acid can be reused, otherwise, should be diluted and then washed out the acid solution.

3, alkali washing

After the end of pickling, NaOH, Na, PO, demineralized water prepared in a certain proportion, the use of dynamic circulation of the way to the heat exchanger alkaline washing, to acid and alkali, so that the heat exchanger plate no longer corrosion.

4, washed

After the caustic washing is done, clean the softened water. Repeatedly rinse the Cooler for Transportation Vehicles for 0.5h, thoroughly remove the residue in the heat exchanger. During the cleaning process, the time of each step should be strictly recorded to check the cleaning effect. In short, after the end of cleaning, to the heat exchanger to suppress the test. Qualified before use.
