Flowmaster-based Simulation of Regulation Performance of Low Flow Water Supply Equipment
Existing secondary water supply research on small flow conditions is less be attention,small flow condi-tions of inefficient operation of the main pump,frequent start-stop problem is becoming a constraint on the urban water supply"last kilometer"low energy consumption,high-quality development of the pain point.The Flowmaster simulation model is established to simulate the low-flow water supply mode of"power frequency auxiliary pump+air pressure tank"to investigate the regulation performance of the pneumatic tank under different flow rates on the demand side.The results show that the"power frequency auxiliary pump+air pressure tank"can reduce the number of pump starts and stops and maintain the stability of the system.Furthermore,the influence of pre-filling pressure of air pressure tank on the regulation performance is studied,the negative impact of pre-filling leakage is elucidated.The relevant engineering recommendations are put forward.
