With the continuous advancement of urbanization, sewage treatment plants are playing an increasingly important role in urban infrastructure. However, in the process of sewage treatment, equipment damage, aging and other problems occur from time to time, among which the agitator is one of the core equipment of the sewage treatment plant, once the failure occurs, it will directly affect the effect of sewage treatment. Therefore, diving maintenance and testing has become an important means to ensure the normal operation of sewage treatment plants.
1. The importance of diving maintenance and testing.
Diving maintenance inspection refers to the operation of equipment inspection, maintenance, and replacement by divers entering the water to ensure the normal operation of the equipment when the equipment of the sewage treatment plant fails. The importance of diving maintenance inspection is as follows:
1.Timely detection and problem solving: Divers can enter the inside of the underwater equipment, directly observe the operation status of the equipment, find and solve the problem in time, and avoid greater losses caused by equipment failure to the sewage treatment plant.
2.Improve the service life of the equipment: Through regular diving maintenance and testing, the equipment can be maintained and maintained in time, prolong the service life of the equipment, and reduce the cost of replacing the equipment.
3.Ensure the effect of sewage treatment: The agitator is one of the core equipment of the sewage treatment plant, and its normal operation is directly related to the effect of sewage treatment. Through the submersible maintenance test, the normal operation of the agitator can be ensured and the sewage treatment effect can be improved.
Second, the process of diving maintenance and testing.
1.Preparation: Divers need to be trained and assessed to ensure that they have the appropriate skills and qualities before diving maintenance and testing. At the same time, you need to prepare diving equipment and tools, such as wetsuits, breathing apparatus, lighting equipment, etc.
2.Launching inspection: After the diver enters the water, the agitator needs to be fully inspected, including the motor, reducer, bearing and other components. At the same time, it is necessary to observe and record the operation of the agitator.
3.Fault diagnosis: According to the inspection situation, the stirrer is trouble-diagnosed. If the faulty part or component is found to be seriously damaged, it needs to be replaced or repaired in time.
4.Repair and replacement: Carry out corresponding repair or replacement operations according to the fault diagnosis results. During the maintenance process, it is necessary to strictly follow the safety operation procedures to ensure the safety of personnel and equipment.
5.Acceptance inspection: After the repair or replacement is completed, the agitator needs to be inspected for acceptance. If everything is in order, the normal operation of the device can be restored.
3. Precautions for diving maintenance and testing.
1.Safety first: Dive maintenance inspections are a high-risk job that must always be a top priority. During the diving process, it is necessary to strictly follow the safety operation procedures to ensure the safety of personnel and equipment.
2.Full Inspection: A full inspection of the equipment is required prior to the diving maintenance inspection. It is necessary not only to check the appearance and structure of the equipment, but also to check the operation and performance parameters of the equipment.
3.Accurate diagnosis: According to the inspection situation, accurate fault diagnosis of the equipment is required. If the diagnosis is inaccurate or incomplete, it can lead to repair failure or delay in repair.
4.Reasonable arrangement of time: Since diving maintenance and testing requires a lot of time and manpower and material costs, it is necessary to arrange time reasonably according to the actual situation. If it is found that the fault is serious or there are many parts that need to be replaced, the work plan and schedule need to be adjusted in time.
5.Detailed records: During the diving maintenance and inspection process, each step and detail needs to be recorded in detail. This will not only help the follow-up fault analysis and treatment work to proceed smoothly, but also provide reference and reference for future work.
In short, diving maintenance and testing is one of the important means to ensure the normal operation of sewage treatment plants. In the process of diving maintenance and testing, it is necessary to strictly abide by the safety operation procedures and pay attention to the details of work such as comprehensive inspection, accurate diagnosis, reasonable time arrangement and detailed records, so as to ensure the smooth progress of diving maintenance and testing and the stable operation of the sewage treatment plant.
