Circulating water filter is a relatively novel filtering device for some people, so today we mainly introduce the matters needing attention about the selection of circulating water filter. I hope that after our introduction, we can bring you a certain amount of s help.
First of all, I would like to introduce the division criteria of circulating water filters.
(1) According to the device installation method of the filter, it can be divided into: full filtration and side filtration. In short, full filtration is a filtering device that can be directly installed on the main road. At present, these two installation methods are also required.
(2) According to the principle of the filter, there can be many kinds of filters: sand filter and walnut shell, laminated sheet, net type, fiber ball, fiber bundle and other filters.
(3) The main difference between the filter installed in the total filtration and the bypass filter is that the pressure loss of the filter installed in the total filtration must be small. If the pressure loss is large, it will affect the flow and velocity of the main pipeline. Because of the need to consider the safety factor of the full-filter rate device, the filter is often used with low accuracy because of the consideration of safety factors. The higher the filter accuracy, the greater the pressure loss and the lower the flow rate. By-pass filtration does not need to consider factors such as pressure loss, so the filters used are often of higher accuracy and better filtering results.
(4) Among the many filtration methods on the market, media filters are rarely designed as full filters. Due to the high pressure loss of the media filters, the filtration accuracy is high and the effect is good.
Things to pay attention to when selecting circulating water filters:
Generally in the cooling circulating water, since the water is circulating, so by-pass filtration is usually adopted, so that not only the filtering effect is better, but the cost performance can be greatly reflected.
