离心式通风机检修时拆卸叶轮,习惯用手工捶打,既不安全又容易使轴头变形。我们针对这种情况,设计制作了一种简易的拆卸器,使用起来十分方便。拆卸器的构造见图1。原理和拆卸轴承的“拉马”一样,只是拉杆钩变成了φ6的钢丝绳,用钢丝绳套在叶轮上,并用钢丝绳的卡扣 The impeller is dismantled when the centrifugal fan is overhauled, and it is customary to beat it by hand. It is neither safe nor easy to deform the shaft head. We designed and manufactured a simple disassembler for this situation, which is very convenient to use. The structure of the detacher is shown in Figure 1. The principle is the same as that of the puller of the disassembly bearing, except that the pull rod hook becomes a φ6 wire rope, and the wire rope is used to cover the impeller and the buckle of the wire rope is used.
