The installation of underwater flanges is one of the important links in the salvage process of the flow pusher in the sewage treatment plant. When carrying out underwater flange installation, certain steps and precautions need to be followed to ensure the accuracy and safety of the installation.
1. Preparations.
Adequate preparation is required before the installation of underwater flanges. First of all, the flange needs to be cleaned and inspected to ensure that its surface is free of impurities and damage. Secondly, you need to prepare the tools and materials required for installation, such as bolts, gaskets, sealants, etc. In addition, installers need to be trained and educated about safety to ensure they understand the precautions and operating procedures during the installation process.
Second, the installation process.
1.Determine the installation location.
First of all, it is necessary to determine the installation location of the flange. According to the actual situation and equipment requirements of the sewage treatment plant, select the appropriate installation location, and ensure that the connection between the flange and the pipeline or equipment interface is firm and stable.
2.Connecting bolts.
Apply an appropriate amount of sealant to the flange, then insert the bolt into the flange hole and use a tool such as a wrench to tighten the bolt. When tightening bolts, care needs to be taken to evenly force them to avoid loosening or damage.
3.Seal inspection.
Once the installation is complete, a seal check is required. A professional seal inspection tool can be used to seal the flange joint to ensure that there is no leakage in the connection.
4.Debug the run.
After the seal inspection is completed, the commissioning operation can be carried out. In the process of commissioning, it is necessary to pay attention to the operation of the equipment, if there is no abnormal situation, it can be put into normal operation.
3. Precautions.
1.When carrying out underwater flange installation, it is necessary to pay attention to safety issues. Installers need to wear professional protective equipment such as wetsuits, gloves, fins, etc. During installation, care needs to be taken to avoid touching hazardous areas and equipment.
2.During the installation process, it is necessary to pay attention to the cleaning and inspection of the flange. If damage or impurities are found on the flange surface, it needs to be treated and replaced in time.
3.When tightening bolts, attention needs to be paid to uniform and appropriate force. Avoid loosening or damage. At the same time, it is necessary to pay attention to prevent the occurrence of bolt slippage or breakage.
4.When performing a seal inspection, it is necessary to pay attention to the method of use and accuracy of the inspection tool. If a leak is found in the connection, it needs to be dealt with and repaired in time.
5.In the process of commissioning and operation, it is necessary to pay attention to the operation of the equipment. If an abnormal situation is found, it needs to be stopped in time for inspection and repair. At the same time, care needs to be taken to avoid the operation of the equipment under abnormal conditions, so as to avoid damage or safety accidents.
In short, the installation of underwater flanges is one of the important links in the salvage process of the flow pusher in the sewage treatment plant. When carrying out underwater flange installation, certain steps and precautions need to be followed to ensure the accuracy and safety of the installation. At the same time, it is necessary to regularly inspect and maintain the equipment to ensure the normal operation of the equipment and the extension of its service life.
