When the municipal pipe network flow basically meets the requirement and the pressure is insufficient, the pressure-superposed water supply is carried out by relying on the super-silent pipe pump in the pipe, the pipe pump in the pipe can run under a high working condition, the redundant kinetic energy is stored in the high stationary flow compensation tank, when the water storage amount of the high stationary flow compensation tank reaches the upper limit, the pipe pump in the pipe stops running, and the high stationary flow compensation tank is used for pressurizing and supplying water, so that the super-silent and high-efficiency energy conservation in the water supply process are realized. The whole system is not contacted with the outside air, is operated in a totally-enclosed way, and is more sanitary and environment-friendly.

Preferably, the high-level steady flow compensation tank is a bag type pneumatic water tank.
The utility model has the advantages and positive effects that: when the municipal pipe network flow basically meets the requirements and the pressure is insufficient, the super-silent pipe pump-in-pipe pressure-superposed water supply is adopted, the pipe-in-pipe pump can operate under a high working condition, redundant kinetic energy is stored in the high stationary flow compensation tank, when the water storage amount of the high stationary flow compensation tank reaches the upper limit, the pipe-in-pipe pump stops operating, and the high stationary flow compensation tank supplies water in a pressurized mode, so that the super-silent and efficient energy conservation in the water supply process are achieved. The whole system is not contacted with the outside air, is operated in a totally-enclosed way, and is more sanitary and environment-friendly. The system has an automatic operation protection mechanism, monitors the water inlet pressure sensor, and when the water supply pressure of the municipal pipe network is too low or the water is cut off, the control cabinet sends out an instruction to stop the operation of the pump set in the pipe; the low-level steady flow compensation tank provides stable water output for a user pipe network when the water supply pressure change is large during the switching operation of the water pump. When the water supply flow of the water pump is less than 25% of the rated flow, the pump group in the pipe stops running, the low stationary flow compensation tank and the high stationary flow compensation tank supply water under the combined action, the low-working-condition high-energy-consumption running of the pump group in the pipe is avoided, and the water supply of a user pipe network is not interrupted due to too low water pressure or water cut-off of a municipal pipe network.
