Waterjet pre-treatment of water

In different regions of our country and its water quality has a great difference, such as in most parts of the north, the water content of calcium and magnesium is relatively high, thus forming the so-called "hard water". As the ultra high pressure water jet pump equipment main medium of water, when the suspended solids or calcium and magnesium content exceeded, will resulting in a greater impact on system seal and high pressure parts service life. Therefore, it is necessary to pre-treatment of water entering the pump. Let's look at how the waterjet pre-treatment of water:

Waterjet cutting machine pre-treatment of water, including water filtration and water softening:

1, The main purpose of water filtration is to remove suspended solids in water, and it is usually realized by using multi-stage series filter device. Filter pump provides an initial pressure for the filter. Filters were equipped with 5μm, 1μm and 0.5μm of PP cotton filter. After triple filtered water will no longer be suspended solids, then after pressurized by a booster pump into the pressurizer. Filter stage usually requires the installation of a pressure differential table, through the filter when the filter clogging cause insufficient water pressure, the system will automatically stop and alarm to alert the operator to replace the filter in time to ensure system security.

2, The methods of softening water generally have boiling, ion exchange, reverse osmosis and other methods. The RH-1000 model softener as an example to introduce the basic principle of water softening and use.

(1) System function: The system uses 20μmPP cotton filter, activated carbon filter and 5μm ultrafilter series filter group, not only can remove the residual chlorine in water and suspended solids, and can effectively ensure the life of the resin. Softener resin used can effectively remove calcium and magnesium ions to achieve the effect of softened water. Softener with automatic regeneration.

(2) Water quality testing: to facilitate the understanding of the situation of water quality, can use water quality test reagent to test the water suspended solids, hardness and PH value. Let's take a look at it.

After softening water quality have a protective effect on the waterjet, prevent it from the "hard water" damage, prolong the service life.
