rotary blower impeller damage reason

Rotary blower product introduction:


Four sliding blades of rotary blower are embedded in the equally divided rotor, and the shaft of rotary blower is fixed in the center of rotor. Bearings are installed at both ends of the shaft and are connected with the front and rear pump covers. At this time, the rotor and the four sliding blades embedded in the rotor form four spaces with different volumes with the inner wall of the cylinder. During the operation of the rotary blower, metal rings or springs push the sliding blades The rotary blower works in three parts: suction stroke, compression stroke and discharge stroke. When the rotary blower rotates, the four sliding blades in the rotor slot produce reciprocating motion, which sucks in, compresses and discharges air, forming wind Machine.


Solutions for collision of rotary blower during transportation and installation:


Vibration of the rotary blower during transportation or installation may cause the fan rotor to deflect, and the rotary blower may not work normally. In case of collision, please pull the rotary blower belt by hand and check whether the fan rotates normally. The rotary blower can rotate normally under the condition of not light or heavy, and the fan has no fault. If the fan cannot be pulled or pulled, but there is a light or heavy feeling, the fan rotor is tilted. At the same time, pull the fan belt until the rotary blower belt can be pulled. When the weight is not felt, please tighten the back cover.

Reasons for damage of rotary blower impeller:


1. The rotary blower has been used for a long time. It starts to age and its service life is shortened. This is normal. You can replace the impeller directly.


2. The problem can be solved by tightening the rivets or replacing them with new ones due to the looseness of rivets and blades.


3. The vibration value of the impeller exceeds the production standard, which causes the impeller to deform and skew. In this case, the impeller needs to be removed and corrected with appropriate tools. The impeller must be leveled and balanced.


4. The surface of fan blade is seriously worn or corroded, including rivet head. The solution is to replace the relative accessories if some rivet heads or blades are damaged. If many of them are damaged, the impeller must be replaced.

The importance of impeller to the operation of rotary blower:


The efficiency of rotary blower is improved. This is because the speed has increased, that is to say, the speed of the impeller has increased. How to improve the impeller speed, which is related to the impeller diameter and slope. If the diameter of the impeller is large, the amount of air generated during the rotation will naturally increase, so the time required to reach a certain amount of air is much shorter. Therefore, if you want to save energy, you can improve the fan impeller. In addition to the shape and size of the impeller, improving the driving direction can also play an important role.
