Fan is a high energy-consuming equipment, a large proportion of electricity consumption of resources in the stone processing, with the current growing shortage of energy and productive and efficient face application, saving energy has become the stone production companies generally concerns, many stone production enterprises to reduce power consumption of the fan as the current important work. Reduce fan power consumption in addition to improving the efficiency of the fan itself, but a reasonable selection of fan adjustment method is the most important, because the load of stone production process and with the ever-changing needs of the majority of fans will need to constantly adjust the flow host load . Inlet vane adjustment, FC (forward multi-blade) fan adjustment feature (after the wing) fans better than BI (backward plate) / AF. Although less efficient than FC fan standalone BI / AF fans, but in VAV systems, due to lower fan power characteristics of a good FC fan wholesale farming, both the power consumed by the fan is almost as livestock breeding, coupled with a small, lightweight FC fan advantages of low rpm fan culture, making it the VAV system more widely. BI / AF fan because of the size of the weight of the price over FC fans rated at the same occasion FRP fan culture, with a high number of revolutions of the shortcomings, it limits its application in small VAV system, but in large and medium load applications, still want to use more efficient BI / AF-type fan. FRP fan culture, Qingzhou Minhua temperature control equipment, Dongying farming fan community is provided by China Qingzhou temperature control equipment plant.
