The maintenance and maintenance of the sewage mixer is an important link to ensure its normal operation and extend its service life. Here are some specific care and maintenance measures:

First, regular cleaning

Clean the transmission part and attachments: regularly clean the transmission part and attachments of the mixer with water to ensure that the transmission part is clean and lubricated. Pay attention to safety in the cleaning process to avoid accidents such as falls. 

Remove silt and debris: check the driving part of the mixer and the mixing part, remove the silt, scum, debris attached to the blade, and ensure that the mixer can operate normally. This also helps to reduce the increase in equipment operation resistance and energy consumption caused by debris accumulation. 

Second, check the status of the equipment

Check the overall structure: check the overall structure of the mixer is firm, if there is loosening, it needs to be tightened in time. This helps prevent the equipment from being damaged due to excessive vibration during operation. 

Check the bearing and lubrication: for mechanical mixers, regularly check the lubrication of each bearing, such as insufficient lubricating oil or poor quality, need to be replenishment or replacement in time. At the same time, check whether the bearing is loose, and if so, deal with it in time. 

Check the electrical part: check the electrical part of the mixer regularly, such as whether the cable is broken, whether there is leakage phenomenon. The normal operation of the electrical part is crucial to the overall performance of the mixer. 

Third, replace the lubricating oil

Regular replacement of lubricating oil: for mechanical mixers, regularly check the cleanliness of lubricating oil of gear box and reducer, such as oil pollution, oxidation deterioration need to be replaced in time. The new machine needs to be replaced after 200-300 hours of operation, and then it can be replaced once in half a year to a year. The replacement interval depends on the device frequency and operating environment. 

Fourth, check the health

Check the mixing shaft and swing: regularly check the mixing shaft lock nut, each connection bolt is loose, and the oscillation of the mixing shaft. Remove the entanglement on the impeller and shaft in time to ensure the normal operation of the mixing shaft. 

Monitor abnormal sound and temperature rise: Check the transfer parts regularly for abnormal sound and temperature rise. If there are abnormal conditions, it is necessary to deal with them in time. This helps to detect and resolve equipment faults in a timely manner and prevent them from expanding. 

Fifth, long-term unused treatment

The equipment does not work for a long time: before the equipment is turned on again after a long time of no work, the insulation of the motor should be checked to prevent damage to the motor and impeller due to the difficulty of starting caused by sediment deposition for a long time. 

Sixth, other precautions

Keep dry and clean: When using the sewage mixer, the equipment should be kept dry and clean to avoid water vapor and dust entering the inside of the equipment to affect the operation. 

Pay attention to the installation location: the installation location of the sewage stirring motor should be selected in a place with good ventilation and avoid the equipment being soaked by rain as far as possible. 

Prevent overload operation: Avoid overload operation of sewage mixer to prevent equipment damage. 

To sum up, the maintenance and maintenance of the sewage mixer involves many aspects, including regular cleaning, checking the status of the equipment, replacing the lubricating oil, checking the operating status and long-term unused treatment. Through the implementation of these measures, the service life of the mixer can be effectively extended and the efficiency of sewage treatment can be improved.
