Problems solved by technology

The existing centrifugal fan unit is directly installed on the locomotive through bolts. When installing the centrifugal fan unit or when the centrifugal fan unit needs to be disassembled from the locomotive for maintenance, it is necessary to completely remove the bolts used for fixing, resulting in its installation or disassembly. The process consumes a lot of time. At the same time, when directly fixing with bolts, it is necessary to accurately align the fixing holes on the mounting bracket with the threaded holes, which is not convenient for installation

Description

technical field [0001] The invention relates to the technical field of centrifugal fans, in particular to a high-maintenance integrated centrifugal fan unit. Background technique [0002] With the development of the economy, the speed of the train is getting faster and faster. While the speed of the train is increasing, higher requirements are put forward for the weight, noise, volume and maintainability of each component. As an important part of the cooling unit, the centrifugal fan unit plays an important role in its performance. The existing centrifugal fan unit is directly installed on the locomotive through bolts. When installing the centrifugal fan unit or when the centrifugal fan unit needs to be disassembled from the locomotive for maintenance, it is necessary to completely remove the bolts used for fixing, resulting in its installation or disassembly. The process consumes a lot of time. At the same time, when directly fixing with bolts, it is necessary to accurate...
