Water filter, water separator, water pipe product comparison

Fire filter is the first line of defense in the water supply chain.

As you know, the water filter is a device for filtering water impurities. The criteria for evaluating a water filter is whether it can really protect the water pump. The most important thing for a quality water filter is the size of the filter's caliber. According to a standard of the world's leading water pump manufacturer, the maximum diameter of a magazine allowed to enter the water pump can not exceed 10 mm without damaging the water pump .

If you choose a poor quality water filter, you should understand that it may cause unimaginable damage to the water pump and water tanker fire truck, which will also cause you heavy economic losses.

The most important thing about fire fighters is the performance of the product in actual combat. An excellent water separator should be attributed to its ability to maintain a balance between water flow at the inlet and outlet. Then we should use scientific quantification to compare them. At the same time, water pressure loss is one of the most common and most easily overlooked issues. How is water pressure secretly reduced inside the water separator?

First of all, ask you to carefully observe each part of the water separator, and each of their sizes. In the comparison process, Xiao Bian put the two water separators in a good "dismemberment". You will see that the size of the outermost (interface) is the largest; followed by the size of the threaded connection on the water separator; when you go inside, you will find that the internal channel structure of some water separators is trumpet type. The size gradually shrinks from the outside to the inside, to the ball valve, often the smallest size. That is, the minimum channel size = ball valve size (except for individual products).

Second, how smooth is the water flow channel in Guancheng Diverter? A non-smooth inner surface increases the friction of the water flow, which in turn reduces the water pressure. This time, the editors could not only look through their eyes but also reached out and touched them.

Water pressure is like a "bullet" of water guns and water cannons. The size of water pressure can directly affect the power of water guns. When it comes to water pressure losses, there are actually basic calculation formulas. Please check "flow calculation, not simply multiplication" and hurry to learn.

For the purchase of suction hoses, the editor has a four-character tip: "bend, light, big, and hard." "Bend" refers to the bendability of the suction pipe. The narrow storage space inside the fire engine is a constant pain for firefighters when they are on the alert. A flexible suction pipe can not only save a lot of space, but also adapt to various fire terrain; "light" refers to the weight of the suction pipe. If a firefighter can pick up one or more suction hoses, then it saves a lot of manpower; "big" refers to the large flow of water. This depends on the area of ​​the suction pipe; "hard" refers to the pressure of the suction pipe. Within a reasonable standard pressure range, the suction pipe can not be deformed or ruptured. This is an "excessive" suction pipe.
