Moreover, it is difficult to get the filter to full capacity in daily life water.Extended DataWhen the filter is working, the water to be filtered is entered by the water outlet, flowing through the filter screen, and entering the pipeline required by the user through the outlet for process circulation. the particle impurities in the water are trapped inside the filter screen.With such continuous circulation, more and more particles are trapped, the filtration speed is getting slower and slower, and the imported sewage is still continuously entering, and the filtration holes will become smaller and smaller, thus, there is a pressure difference between entering and exporting;When the tolerance d

How to install the filter of water mist sprinkler system correctly The roof fire tank is usually filled with water,When a fire occurs, the nozzle is chrome-plated and melted after the temperature reaches a certain temperature (usually 68 °C,The water in the pipe is automatically ejected under the action of the roof fire water tank,At this time, the wet alarm valve will automatically open,The pressure switch inside the valve is automatically opened,This pressure switch has a signal line and a fire pump chain,The pump starts automatically.Then the spray pump provides the water of the pool to the pipe network through the pipeline,The whole fire system started working.Fire sprinkler system is a fire fighting device,It is a fixed fire protection facility widely used,It has the features of low price and high fire fighting efficiency.According to different functions, it can be divided into two forms: manual control and automatic control.System installation alarm device,Can automatically alarm in the event of a fire,
