Sewage mixer overload may cause the following hazards:

1. Shortened equipment life: the overload of the mixer will lead to excessive pressure and heat on the motor and other key components, thus accelerating the wear and aging of the equipment. For mixers running at high power for a long time, poor motor heat dissipation may lead to damage, which will negatively affect the service life of the equipment.

2. Endangering user safety: Under overload, the mixer may be out of control, such as stopping or flying out food residues. This unpredictable behavior can cause harm to the user, especially when the operator is near the device.

3. Affect the mixing effect: overload may cause the operation of the mixer to be unstable, which will affect the mixing effect. The power loss increases and the load may be affected, which not only wastes energy, but also may not achieve the desired sewage treatment effect.

4. Increase maintenance costs: Overload operation will accelerate the wear and tear of equipment, leading to more frequent repair and replacement of parts, thus increasing maintenance and maintenance costs.

5. Potential safety accidents: In extreme cases, overload may cause the motor temperature to be too high, and even cause safety accidents such as fire. In addition, if the mixer is a high-speed diving type, overload may also cause the shell of the mixing container to be damaged by the impact of high-speed mixing, or even explode.

In summary, the hazards of sewage mixer overload include shortening the life of equipment, endangering the safety of users, affecting the mixing effect, increasing maintenance costs and possibly causing safety accidents. Therefore, the operating load of the sewage mixer must be strictly controlled to avoid the occurrence of overload.
