1, the advantage of series connection is that the total pressure of the water supply system can be increased by using multiple pressure tanks in series, which makes the water supply more stable, especially when large-flow water supply is needed, and the series pressure tanks can meet the needs of the water supply system. Disadvantages are: when multiple pressure tanks are used in series, the pipeline length and resistance will increase, which will easily lead to the increase of water supply resistance and energy consumption, especially in the case of long distance and large flow, which will lead to the increase of energy consumption, which is not conducive to system operation.
2. The advantage of parallel connection is that multiple pressure tanks can be used in parallel, which can increase the total flow of water supply system, especially when large flow of water is needed, and the parallel pressure tanks can meet the needs of water supply system. The disadvantage of parallel connection is that multiple pressure tanks are used in parallel connection, which may easily lead to insufficient total pressure of water supply system, especially in the case of high-pressure water supply, which may affect the quality and stability of water supply.
3. Considering the required water supply flow and pressure, pipeline length and resistance, series connection is better than parallel connection.
