Second, the fan type 1, each fan casing is made right rotation or left rotation of two types. 2, the export position of the fan exit angle indicated by the cabinet. 3, fan drive: There A, B, C, D four. Third, the structure of the main blower fan motor Direct distribution consists of the impeller, housing, air inlet and other units. . 1. Impeller: backward by 12 wing-shaped blade, curved front plate and the plate after plate components. With a cover or cast aluminum alloy, and static and dynamic balance correction, air good performance axial fan, high efficiency, smooth operation. 2. Chassis: made of two different types. No2.8 ~ 12 chassis made whole, can not be disassembled. Chassis No16 ~ 20 made three open, except along the horizontal plane separated into two and a half outside 5.5kw axial fans, the upper half is further divided into two halves along the vertical centerline, with the bolt connection. 3. inlet: 8 # axial fan made whole, mounted on the fan side, parallel to the axial cross-section shape of the curve, the gas can smoothly enter the impeller, and the loss is small. 4. Transmission Group: from the spindle, bearing housing, bearings, pulleys or coupling components. On the Development of axial fan status. We want to know how to understand the status of the development of a product, have sufficient grasp talk about current developments, to be able to develop a strong, let's take a look at the status quo axial fan is like. General from its related industries for analysis, the majority of air-conditioning host plant is based on empirical data table cold resistance and heat transfer needs to matching fan. Because fans also need to overcome resistance in addition to resistance cooler outside the rest of the system, such as the air conditioning unit housing some ribs, compressor and cooler connection pipe and valves, etc., in addition to lodging cooler fins can also cause changes in local resistance. Therefore, there will often match some of axial fan unit in low wind, high resistance, high-power conditions t3511 running axial fans, resulting in lower overall energy efficiency, the fan motor burned easily overload condition occurs. How scientific and rational matching axial fan, fan manufacturers require their users to communicate more technical level. Axial fan is an application of this product is very popular product, but also a very promising development, as the industry, to take to seize opportunities, meet a better development, this article is provided by axial fans.
