Method and meaning of filter type compilation
2014-08-08 Number of attention:
A filter is a small device that removes a small amount of solid particles from the liquid and protects the normal operation of compressors, pumps, meters and other equipment. When the fluid enters a filter cartridge with a certain size of filter mesh, its impurities are blocked, and the clean filtrate is discharged from the outlet of the filter. When cleaning is needed, the removable filter is only needed. The cartridge is removed and reloaded after processing, so it is very convenient to use and maintain. Garbage debris in pipelines often causes damage to equipment, such as scale, rust, composite sealant, cinder and other solid particles may enter the pipeline system, in order to prevent the adverse effects of dust and particles contained in the fluid on equipment, filter is often used in the pipeline. In order to prevent the pump from the construction waste left in the pipeline, the upper reaches of the pump can be equipped with a filter device. Filters can filter out solids in liquids or gases to protect equipment from damage and prevent pipeline blockage.
