The use of filters for filter bags has become more and more widespread. When there is a demand, there will be supply, there will be more and more manufacturers, and the quality will be uneven. This will result in the user’s choice of purchase. A certain amount of trouble.
The use of filters for filter bags is becoming more and more widespread, and there will be supply when there is a need to use them, and the quality of the filter bags will become more and more uneven. This will result in a certain degree of customer satisfaction. Purchase caused a certain degree of trouble, when we are buying, we must first consider the characteristics of the filter bag: according to the bag’s resistance coefficient, static dust removal efficiency, dynamic dust removal efficiency, filter dynamic resistance, regeneration resistance coefficient and dust stripping rate selection The price of the bag.
The filter cloth bag of the filter must not have its jumper, broken wire, black spot, puncture hole, defect or the connection of the filter cloth. This is the standard filter cloth bag. According to the nature of the filter dust, choose temperature-resistant filter material, corrosion-resistant filter material, anti-static filter material or hydrophobic filter material.
Filter cloth bags in the filter during the purchase process also need to pay attention to the filter cloth with the fracture strength, elongation at break, the bag’s warp and weft load elongation, the filter material burst strength and so on. The economical performance of the filter bag must be combined with the technical performance. Cost-effective is good.
According to the working principle of the filter, the prefilter that is currently most suitable for home use should be a backwash filter. The working principle of the backwash filter is: When the filter needs to flush the retentate, the reversal of the water flow is achieved manually or automatically by adjusting the reversing multi-way valve of the filter itself, so that the original water flow from the net of the filter (core) The water side flows to the raw water side to achieve the purpose of recoil.
