The daily maintenance of the sewage mixer is essential to ensure its normal operation, extend its service life and improve the efficiency of sewage treatment. Here are some key daily maintenance tips:

First, cleaning work

Regular cleaning: Regular cleaning of the mixer transmission parts and attachments, including blades, mixing shafts, etc., to ensure that they are free of silt, scum, debris, etc. This helps reduce friction and wear and increases mixing efficiency. When cleaning, use water or appropriate detergent, and ensure safe operation to avoid injury.

Check and remove entanglement: Regularly check whether there is entanglement on the mixing shaft, such as rope, plastic bags, etc., and remove it in time. These entanglements will not only affect the normal operation of the mixer, but also may cause damage to the equipment.

Second, lubrication and inspection

Inspection and replacement of lubricating oil: For mechanical mixers, the cleanliness of lubricating oil of gear box, reducer and bearing should be checked regularly. If the oil is dirty, oxidized and deteriorated, it should 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 six months to one year, depending on the use of the equipment and the manufacturer's recommendations. For the hydraulic mixer, the oil level and oil quality of the hydraulic system should be checked regularly, and it should be replaced in time if necessary.

Inspection of bearings and seals: Check the bearings and seals of the agitator regularly to ensure that they are in normal operation and do not leak. Lubricate when necessary to reduce friction and wear. At the same time, check whether the bearing is loose, if there should be timely treatment.

Third, electrical and mechanical inspection

Electrical system inspection: Regularly check the electrical parts of the mixer, including cables, wiring, control panel, etc., to ensure that they are not broken, leakage and other phenomena. If any abnormality is found, handle it in time to prevent electrical faults.

Mechanical structure inspection: check whether the overall structure of the mixer is firm, and whether the connecting bolts and locking nuts are loose. If it is loose, tighten it in time to prevent damage caused by vibration.

Operation monitoring: During the operation of the mixer, attention should be paid to monitoring its sound, temperature and other operating conditions. If there is abnormal sound or excessive temperature, stop the machine in time to check and deal with it.

Fourth, other precautions

Avoid no-load operation: When the mixer is not fully immersed in the liquid, it is strictly prohibited to operate no-load to avoid danger and equipment damage.

Check after the shutdown: Before the equipment is turned on again after a long time without working, the insulation performance of the motor should be checked to prevent startup difficulties or damage to the motor due to sediment deposition for a long time.

Scheduled Maintenance contract: Consider a scheduled maintenance contract with an equipment manufacturer or professional service provider who can regularly inspect and maintain the equipment to ensure it is operating at its best.

To sum up, the daily maintenance of the sewage mixer involves many aspects such as cleaning, lubrication, electrical and mechanical inspection. By regularly implementing these maintenance measures, the service life of the mixer can be effectively extended, the efficiency of sewage treatment can be improved, and the production loss caused by equipment failure can be reduced.
