Connection method of sewage pump inlet and outlet flange
There are mainly the following connection methods for the inlet and outlet flanges of sewage pumps:
1. Butt welding flange connection
Connection method: Assemble the flange at the end of the pipe and connect it by butt welding.
Features:
Simple structure, good sealing performance, strong bearing capacity.
Requires professional welding skills, and is prone to welding quality problems.
2. Bolted flange
Connection method: A sealing groove is opened on the end face of the flange, and a sealing ring is installed in the groove. After the butt is well connected, the pipeline is tightly connected with bolts or studs.
Features:
Simple connection, easy installation, easy maintenance and replacement during use.
Different bolted flanges also have different sealing forms, such as flat sealing, flange sealing, flange surface sealing, etc.
3. Clamp flange connection
Connection method: Use a clamp to tightly fix the flange connection part together without using bolts or welding.
Features:
Good sealing performance, low dust content, and convenient connection.
The scope of application is narrow, and problems such as clamp deformation are prone to occur.
When selecting and using flange connection methods, the following points should be noted:
Select and use strictly in accordance with the flange connection method, sealing form and flange material requirements.
When checking the flange sealing, pay attention to check whether there are damage or cracks around the flange cover, whether the sealing gasket is damaged or aged, etc.
When replacing the flange, pay attention to cleaning the corrosion, oxides and other impurities of the flange connection part, and ensure that there are no sediments and debris on the pipe joints to avoid affecting the connection effect.
Do not use too much force when connecting to avoid damaging the flange connection part or affecting its sealing performance.
In short, the correct selection and use of the appropriate flange connection method plays an important role in improving the efficiency and service life of the sewage pump.
