Application scenario：This equipment is used for remote secondary pressurized water supply for equipment cooling and spray dust reduction in coal mines. Solved the problem of equipment damage caused by excessive pressure fluctuations in the secondary pressurized water supply underground. The inlet water is depressurized and filtered to ensure the cleanliness and constant pressure of the equipment water, prolong the service life of the equipment, and improve production efficiency. This product is a vertical 4-cylinder dual channel two-stage filtration structure that can be manually back-washed in real time. The filter element is made of multi-layer high-strength stainless steel and can be back-washed multiple times. It has the advantages of constant pressure, high filtration accuracy, and long service life.
