As a kind of improvement, be provided with negative pressure prevention and controller between described water inlet pressure sensor and the described pressure pump group, described negative pressure prevention links to each other with described frequency-conversion control cabinet with controller.
As further improvement, be provided with the voltage stabilizing pressure maintaining tank between described pressure pump group and the described delivery port pressure sensor.
As further improvement, described pressure pump group comprises at least two water pumps, is arranged in parallel between at least two described water pumps.
The non-negative-pressure variable frequency water supply facilities that the utility model provides, owing to be provided with the delivery port pressure sensor between described outlet pipe and the described pressure pump group, described water inlet pressure sensor, described delivery port pressure sensor all links to each other with frequency-conversion control cabinet with described pressure pump group, water inlet pressure sensor and delivery port pressure sensor are with the pressure signal that detects, feed back to frequency-conversion control cabinet, frequency-conversion control cabinet is regulated the operation of pressure pump group according to signal value, thereby not only take full advantage of the surplus pressure of tap water pipe network in the non-negative-pressure variable frequency water supply facilities running, reduced water supply consumption, need not to build reservoir, saved fund, and water system is full-closed structure, non-secondary pollution, environmentally-friendly sanitary.
Owing to be provided with negative pressure prevention and controller between described water inlet pressure sensor and the described pressure pump group; described negative pressure prevention links to each other with described frequency-conversion control cabinet with controller; thereby when water inlet pipe pressure drops to the tap water pipe network protection pressure of setting; negative pressure prevention and controller are adjusted until shut down non-negative-pressure variable frequency water supply facilities running status; guarantee that water inlet pipe pressure no longer reduces, and shields to tap water pipe network.
Owing to be provided with the voltage stabilizing pressure maintaining tank between described pressure pump group and the described delivery port pressure sensor, thereby when user's water supply volume was very little, the non-negative-pressure variable frequency water supply facilities entered the shutdown resting state automatically, kept user's pipe network water by the voltage stabilizing pressure maintaining tank.
Because described pressure pump group comprises at least two water pumps, be arranged in parallel between at least two described water pumps, thereby the non-negative-pressure variable frequency water supply facilities drops into number of units and frequency conversion output frequency by frequency-conversion control cabinet control water pump, the realization constant pressure water supply.
