Question:

I'm cleaning the hood myself. They're all taken apart

I am cleaning the hood, have been taken apart, the impeller fastening screws are screwed down, but the impeller can not get down, can only move up and down

Answer:

The second is the impeller from the top of the motor shaft set on the shaft, nut tight. But the fastening nut of second kinds of methods is concealed relatively, often have a cap to cover, be not easy to discover.
Check that the fastening screws are on the shaft and the side of the shaft,Without any screws, now estimated to be the impeller and shaft is rusty, you will smoke machine upside down, axial gap point sink in some oil, wait a minute, with pliers jaw pad a piece of cloth, the clamping head, the other hand rotating impeller, spinning slowly, as long as not too serious corrosion can be separated out.
Since there are fastening screws, generally there will be no card ring, the top is not necessarily silkSince you can move up and down, it is estimated that the spindle is a bit greasy, stuck, you use the steel ball to grease the head, and then add some oil to the spindle head and the wind wheel, and so on, you can pull it out
You can move up and down in this situation, not the impeller, but the whole motor rotor follows.There are two ways to fix the impeller. One is that the impeller has a shaft sleeve, and the fastening screw is screwed in from the back of the impeller to bite the motor shaft. This fastening screw is relatively exposed and easy to find.
