| The faning machine is an important equipment in the air-conditioning system of the railway passenger car. In order to make sure the safety operation of the air-conditioning system, the faning machine must be inspected frequently. There are two main methods for the inspection of faning machine. One is repairment, another is measurement. But presently, these two machines are also shortage in our country. Based on practices of the air-conditioning system and pratical calculation. A set of flexibility disassembling device which can be applied for variety faning machine with different diameters of axle. This disassembling device makes the inspection of the faning machine on field engineering more easily. After studying the standard inspection paper for faning machine, an integral assay programme which can be used for both axial flow faning and centrifugal faning is also introduced. That is axial flow faning will be inspected in the air-intake wind-pipe programming system and the centrifugal faning will be inspection in the air-outtake wind-pipe programming system. This integral programme system not only reduces device and the floor area, but also makes the whole inspection easy for operators. The using of orifice meter in this programme makes the flow measurement convenience. This programme system adopts fuzzy control system which largely increases the control-quality of input-air and wind pressure. The software-control system for this assay programme system is based on the Windows system and VB6.0. Through researching on project practice, some teclinologic difficults related to the inspection of faning machine are solved and it will do very good things to enhance the inspection level. |
