For further strengthening impact and the vibrations that prevent the pipe network end, described ftercompction water pump with the constant voltage pumping line on be connected with the flexible coupling of rubber.
Adopt such structure, the utility model has the advantages that:
1, no water storage device and associated conduit, equipment and device, floor space is little, can save the one-time construction investment.
2, no water storage link can be eliminated the possibility of the secondary pollution that tap water brings the user.
3, make full use of the pressure of former municipal tap water pipe network, energy conservation helps reducing running cost.
4, by the top water inlet and the bottom suction of pre-compensating water supply tank, the vacuum compensation device on the utilization jar can be eliminated the negative pressure influence to city planting ductwork.
5, set up the constant voltage water pump, when the low discharge water, only start low power constant voltage water pump pressurization, fully energy conservation.
6, utilize the compensation water supply tank as a buffer, can stablize the pressure of pipe network end effectively, prevent to change impact and vibrations, the stability of maintenance system water pipe.
