Rubber joints have a wide range of applications, and are mostly used for pump connection, especially in sewage treatment plants. So how to use rubber flexible joints in sewage treatment plants?
1. The appropriate model must be selected according to the working pressure, connection method, medium and compensation amount of the pipeline, and the number should be selected according to the noise reduction displacement requirements.
2. When the pipeline produces instantaneous pressure and is greater than the working pressure, a softer acid-resistant rubber joint with a gear higher than the working pressure should be selected. (For example: when the instantaneous pressure of the pipeline is greater than 1.0MPa, a joint of 1.6MPa should be used. When the instantaneous pressure is greater than 1.6MPa, a 2.5MPa joint should be used.)
3. When the pipeline medium is acid, alkali, oil, high temperature and other special materials, a joint with a gear higher than the working pressure of the pipeline should be selected.
4. The flange connecting the flexible joint of acid and alkali resistant rubber shall be a valve flange or a flange complying with GB / T9115.1 (RF).
5. The normal suitable medium for acid and alkali resistant rubber soft joints is ordinary water with a temperature of 0-60 ° C. Special media such as oil, acid and alkali, high temperature and other corrosive and hard textures should be selected with the corresponding special resistance. Material rubber joint , cannot be used blindly or universally.
6. When the acid and alkali resistant rubber joint is used at the inlet and outlet of the pump, it should be located near the pump side, and a metal reducer joint should be installed between the pump and the large diameter reducer.
The rubber joints used in sewage treatment plants are very frequent. It is even more important to ensure the quality of the products.
