During the operation of sewage mixer, in order to avoid overload, the following measures can be taken:

First, regular inspection and maintenance

1. Conduct a comprehensive inspection of the sewage mixer regularly, including key components such as motors, bearings and blades, to ensure that they are in good working condition.

2. Maintain the equipment regularly, such as replacing lubricating oil, cleaning internal impurities, etc., to reduce the friction and resistance of the equipment during operation.

Second, reasonable control of load

1. According to the scale and needs of sewage treatment, the power and speed of the mixer are reasonably selected. In general, the power of the sewage mixer is between 2 kW and 30 kW, and the speed is between 30 RPM and 150 RPM. Avoid choosing too much power or too high speed to reduce the risk of overload.

2. During the mixing process, substances such as lubricating oil and water can be appropriately added to prevent the material from adhering to the mixer, thereby effectively reducing the motor load.

Third, monitoring and protection

1. Install ammeter or power meter and other monitoring equipment to monitor the current and power changes of the sewage mixer in real time. Once an abnormal increase in current or power is found, immediate measures should be taken to prevent overload.

2. The mixer is equipped with overload protection devices, such as electromagnetic protectors, thermal relays or electronic protectors. These devices can automatically cut off power when the current exceeds the rated value, protecting the motor from damage.

Fourth, operating standards

1. Follow the operating procedures, start and stop smoothly, avoid violent vibration equipment. Caution should be exercised during operation to avoid unnecessary impact and load on the device.

2. It is forbidden to run the mixer in excess of the carrying capacity of the equipment to prevent overload.

In summary, through regular inspection and maintenance, reasonable load control, monitoring and protection and standardized operation and other measures, can effectively avoid the sewage mixer in the operation of the overload situation. The implementation of these measures can ensure the stable operation of the equipment, extend the service life, and improve the efficiency of sewage treatment.
