What are the causes of rotary blower impeller damage?

Rotary blower product introduction:

Four sliding plates of the rotary blower are embedded in an equally divided rotor. The shaft of the rotary blower is fastened to the center of the rotor. Both ends of the shaft are equipped with bearings, which are connected with the front and rear pump covers and installed on the eccentric cylinder block. At this time, the rotor and four sliding plates embedded in the rotor form four spaces with different volumes with the inner wall of the cylinder block. During the operation of the rotary blower, The metal ring or spring pushes the sliding vane to move at a uniform speed along the inner wall of the cylinder. The cylinder body of the rotary blower is composed of the suction port, the air guide slot at the suction port, the air outlet, and the air guide slot at the exhaust port. The working process of the rotary blower is composed of three parts: the suction stroke, the compression stroke, and the discharge stroke. When the rotary blower rotates, the four sliding vanes in the rotor slot will produce reciprocating motion to draw air in Compress and discharge to form a fan.

Solution to collision of rotary blower during transportation and installation:

Vibrating the rotary blower during transportation or installation may deflect the fan rotor, and the fan may not work properly. In case of collision, first pull the fan belt manually and check whether the fan rotates normally. The fan can rotate normally when it is neither light nor heavy, and the fan has no fault. If the fan cannot be pulled or pulled, but it feels light or heavy, it indicates that the fan rotor has tilted. Pull the fan belt at the same time until the fan belt can be pulled. When you can't feel the weight, please tighten the rear cover.

Causes of rotary blower impeller damage:

1. The fan has been used for a long time, and it begins to age, which shortens its service life. This is normal. It is OK to replace the impeller directly, which is needless to say.

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

3. The vibration value of the impeller exceeds the standard specified in the production, which makes the impeller deformed and skewed. In this case, it is necessary to remove the impeller and correct it with appropriate tools until it is flat, and the impeller balance work should be done well.

4. The surface of fan blades is severely worn or corroded, including rivet heads. The solution is that some rivet heads or blades are damaged, so it is better to replace their corresponding accessories. If many of them are damaged, new impellers must be replaced.

Importance of impeller to the operation of rotary fan:

The working efficiency of the fan has been improved. This is because the speed increases, that is, the speed of the impeller increases. How to increase the speed of the impeller is related to the diameter and slope of the impeller. If the diameter of the impeller is large, the amount of air generated during 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.
