Weight, maintenance management inconvenience and run the problems such as uneconomical so that it is difficult to the demand meeting modern people to supplying water.
At present, owing to the water supply capacity in tap water pipe network is not enough or is limited to the structure of building itself, need
User with installing secondary water-supply equipment before waterpipe additional, thus meet user to the hydraulic pressure of water, the requirement of the water yield.And it is existing
The input of secondary water-supply equipment is directly connected to the municipal water use pipeline in city, owing to current water pollution problems is very serious,
If being not provided with some defecators, then it is difficult to ensure that the safety of water quality.
In order to solve this problem, document CN 105804164 A proposes the monitoring of a kind of band and purification function energy-saving
Frequency-changing water supply device, by adding integrated ultraviolet line sterilizing unit in the front end of supply equipment, purifies variable frequency water supply.
But this equipment clean water quality sterilizes only with ultraviolet sterilization apparatus, can not remove the impurity in water, bulky grain, dirt
Dye thing etc., it is impossible to tackle the problem at its root.
Existing frequency-changing water supply device, still also exists shortcomings such as having relatively costly, volume is relatively big, installation inconvenience.For
Solve this problem, have the document much prior art improved in succession to be disclosed, such as document CN 204510337 U
Disclose a kind of frequency-changing water supply device, by annexations such as MODEL VERTICAL MULTISTAGE PUMP and various valve, converters, reach structure
Compact, the effect of stable performance, but, the volume that MODEL VERTICAL MULTISTAGE PUMP takies is the biggest, the articulamentum of this frequency-changing water supply device
Level is the most more, the most easily causes confusion, and causes that structure is numerous and diverse, the problem of installation difficulty.

Effect realize variable frequency water supply, its principle is: when user's water consumption is less than the water yield of a water pump, and system is according to water
Amount change, makes a water pump (being assumed to the first water pump) run, and when water consumption increases, in tubing, pressure declines, and at this moment presses
Force transducer sends controller to the signal detected, signal is judged by controller, issues instructions to the first water afterwards
Pump, and then control the motor of the first water pump, make motor speed accelerate, it is ensured that system pressure is constant.
Otherwise, when water consumption reduces, make the motor speed of the first water pump slow down, to keep constant voltage.
When water consumption is more than the water yield of a water pump, the first water pump is switched to power frequency operation, and the second water pump starts to become
Frequently speed governing operation, when water consumption is less than the water yield of two water pumps, it is possible to be automatically stopped one or two water pump operations.Cause
This, during whole service, remain that intrasystem hydraulic pressure is constant, makes the first water pump and the second water pump always work in height
