With the acceleration of urbanization, the importance of wastewater treatment plants is becoming more and more prominent. As one of the key equipment of the sewage plant, the normal operation of the agitator is crucial to the entire sewage treatment process. However, due to various reasons, agitators sometimes malfunction or damage and need to be inspected and repaired. This article will introduce a method suitable for underwater agitator inspection and repair to help you complete the salvage work of sewage plant equipment.
1. Preparations.
Before proceeding with the inspection and repair of the underwater mixer, the following preparations need to be made:
1.Understand the equipment situation: understand the model, specification, operation status and other information of the agitator in order to determine the appropriate maintenance plan.
2.Prepare tools and materials: Prepare various tools and materials needed for underwater repairs, such as wetsuits, goggles, oxygen cylinders, repair tools, etc.
3.Arrange professionals: Underwater maintenance is a technically demanding job that requires professional divers and maintenance personnel to carry out the operation.
4.Develop safety measures: In order to ensure the safety of underwater maintenance work, it is necessary to formulate corresponding safety measures, such as pre-dive safety inspections, emergency rescue, etc.
2. Diving inspection.
Divers need to follow these steps for an underwater mixer check:
1.Approach the device: The diver approaches the agitator slowly, taking care not to touch surrounding obstacles.
2.Check the equipment: The diver checks whether the appearance and structure of the agitator are in good condition, and whether there is damage or wear to the impeller, motor and other parts.
3.Photographic recording: Divers take photos and record the mixer for subsequent analysis and maintenance.
4.Determine the maintenance plan: according to the inspection situation, formulate the corresponding maintenance plan, such as replacing parts, adjusting the position, etc.
3. Maintenance operation.
According to the established maintenance plan, the diver needs to carry out the corresponding maintenance operation:
1.Replacement parts: If some parts of the agitator are badly damaged and cannot be repaired, new parts need to be replaced. Divers need to have spare parts ready and replace them underwater.
2.Adjust the position: If the agitator is not positioned correctly, it will affect its normal operation. Divers need to use the appropriate tools and materials to adjust and fix the position of the agitator.
3.Cleaning equipment: Because the agitator runs in water for a long time, it is susceptible to contamination by sludge and impurities. Divers need to clean the equipment to remove dirt and impurities from the surface.
4.Repair the damage: For some minor damage and wear, the diver can repair it with the appropriate materials and tools. For example, impellers are repaired with wear-resistant coatings to extend their service life.
4. Safety precautions.
When carrying out the inspection and maintenance of underwater agitators, the following safety precautions need to be noted:
1.Ensure adequate oxygen: Divers need to maintain adequate oxygen** underwater to avoid dangerous situations such as hypoxia.
2.Be aware of the current and pressure: The current and pressure underwater may affect the diver and equipment, so you need to be safe.
3.Avoid over-fatigue: Underwater maintenance is a physically demanding activity, and divers need to take care to avoid over-fatigue to avoid accidents.
4.Follow safety regulations: When carrying out underwater repairs, it is necessary to strictly follow the relevant safety regulations and operating procedures to ensure the safety and smooth progress of the work.
5. Summary. This article introduces the methods and steps applicable to the inspection and maintenance of underwater mixers, including preparation, diving inspection, maintenance operation and safety precautions. By following these steps and methods, the salvage of the sewage plant equipment can be completed, ensuring the normal operation and maintenance of the agitator. At the same time, it is necessary to pay attention to safety issues to ensure the smooth progress of the work.
