As the economy develops, people's living standards are getting better and better. When people clean their homes, their first choice is no longer a broom, but a vacuum cleaner.

However, when the vacuum cleaner is used for a long time, the motor of the vacuum cleaner must be maintained and replaced. Before maintenance and replacement, one must face a difficult problem-how to disassemble the vacuum cleaner motor. So let's take a look at the disassembly and assembly steps of the vacuum cleaner.

Vacuum cleaner disassembly method

Step 1. Disassemble the fan

Generally, the fan cover of the vacuum cleaner is buckled on the bearing cover, so we can pry the cover off with a flat-blade screwdriver, and then remove the fan cover.

Step 2. Remove the guide wheel

Hold the impeller tightly with one hand, and use a wrench with the other hand to loosen the fastening nut. After unscrewing, remove the backing ring, washer, impeller and other parts in turn, and remove the guide wheel.

Step 3. Remove the brush

Use an electric soldering iron to solder the lead joints of the stator winding coils.

Step 4. Disassemble the bearing cup

In a general vacuum cleaner, the bearing cover and the casing are connected by four rivets. When we disassemble, we must prepare for assembly, which is to ensure that the stator and the armature are concentric. Generally, we need to make a small eye around the original rivet to make a mark.

Step 5. Pull out the bearing cap

In this process, care should be taken to protect the case to prevent damage to the case and affect subsequent assembly.

Step 6. Pull out the armature

This step is generally based on the wear of the front and rear rolling bearings on the armature shaft to determine whether to disassemble. That is, if the wear is not serious, you don't need to remove it; if the wear is serious, you must use a special tool to remove it.

In summary, dismantling the vacuum cleaner is mainly divided into two parts, one is the fan disassembly method, and the other is the motor disassembly method. As long as the correct method is mastered, the vacuum cleaner can be disassembled smoothly.
