Water tank 700 is maintained or is cleared up.
And specific water-supply control includes in actual water supply process：Dynamic water-pressure adjustment modes and cistern water supply mould
Formula；
Wherein, dynamic water-pressure adjustment modes comprise the steps：
Step 1, when the pressure value that first pressure sensor detects be not less than P1 when, detected by second pressure sensor
The pressure value analysis water consumption arriving, and execution step 11 and step 12；Step 11, the pressure detecting when second pressure sensor
When value is less than P4, then controller controls water pump to increase pump-out, until the pressure value that second pressure sensor detects is equal to P4
Or water pump reaches oepration at full load；Step 12, when the pressure value that second pressure sensor detects be more than P4 when, then controller control
Controlling the water circulation pump reduces pump-out, until the pressure value that second pressure sensor detects is equal to P4 or water pump shuts down.Specifically,
When the pressure value that first pressure sensor detects is not less than P1, represent that the output of city planting ductwork is sufficient, starting mode of pump is taken out
Water, controller controls operation equipment according to the pressure value that second pressure sensor detects, and concrete control method is as follows：When
When the pressure value that two pressure transducers detect is less than P4（Now represent that user's water consumption increases）, become in controller control water pump
Frequency module frequency raises, and motor speed increases, output（The water yield that equipment water pump is taken out）Increase, if the detection of second pressure sensor
The pressure value continuous decrease arriving, then frequency-variable module frequency persistently raise, motor speed persistently increases, until all water pumps at full capacity
Run or the pressure value that detects of second pressure sensor to be equal to the frequency of frequency-variable module in P4, and water pump be at the uniform velocity to raise, the
When the pressure value that two pressure transducers detect is equal to P4, then the frequency of frequency-variable module no longer changes after being adjusted to be worth accordingly.
Conversely, water side pressure rise（Represent that water consumption is declining）When, frequency-variable module frequency accordingly declines, and output declines, and second
The pressure value that pressure transducer detects persistently raises, the corresponding continuous decrease of frequency-variable module frequency, until user's useless regimen condition,
Water pump quits work, and when user uses water again, the pressure value that second pressure sensor detects reduces, and water pump continues to start work.
Step 2, when the pressure value that first pressure sensor detects be less than P1 be not less than P3 when, passed by second pressure
The pressure value analysis water consumption that sensor detects, and execution step 21 and step 22；Step 21, when second pressure sensor detection
When the pressure value arriving is less than P4, then controller controls water pump operation and reduces the pump-out of water pump, until first pressure sensor
The pressure value detecting is more than P2.Specifically, when the pressure value that first pressure sensor detects is less than P1, represent municipal administration pipe
The water-supply shortages of net, and the pressure value that second pressure sensor detects is less than P4, shows that water consumption is larger and user
The situation of hydropenia, now, output cannot meet the requirement of water consumption, then the separate unit water pump in non-negative pressure water-supply installation leads to
Electricity runs, and controller controls the frequency-variable module of this water pump to reduce frequency and reduce motor speed, to realize reducing pump-out, until
The pressure value that first pressure sensor detects is more than P2 then it is assumed that the output of city planting ductwork and the pump-out of water pump are equal,
Then water pump is continued to run with this state to ensure that user side has water can use.And if the pressure that detects of first pressure sensor
Value continuous decrease is less than P2, then further reduce the pump-out of water pump, until the pressure value that first pressure sensor detects
More than P2.In the case that output cannot meet water consumption, execution step 21 can make city planting ductwork output come the water yield with
The pump-out of water pump trends towards balancing, and realizes the effect of continuous water supply, and non-negative pressure water-supply installation of the prior art is in municipal administration
Ductwork pressure is consistently less than will directly shut down during P1, and now city planting ductwork is still able to outwards supply water, and is only water shortage, and
Above-mentioned steps 21 can be implemented in the case that city planting ductwork has output, extends water supply time to greatest extent, improves and supply water
Reliability.
Step 22, when the pressure value that second pressure sensor detects be more than P4 when, then controller control water pump reduce take out
The water yield, until the pressure value that second pressure sensor detects is equal to P4 or water pump shuts down.Specifically, when first pressure passes
When the pressure value that sensor detects is less than P1, represent the water-supply shortages of city planting ductwork, by reducing the frequency of pump variable frequency module
Rate simultaneously reduces motor speed, so that the pressure value that second pressure sensor detects levels off to P4, if the inspection of second pressure sensor
The pressure value measuring is more than P4（Show that user's actual used water is fewer and feweri）, continuous by continuous reduction frequency-variable module FREQUENCY CONTROL
Reduce motor speed, constantly reduce water pump frequency, and constantly reduce pumping for water pump amount, until user does not use water, water pump stops
Machine, once user's water, water side detects pressure drop, and water pump runs immediately, by stablizing water outlet end pressure so that pump-out
Level off to balance with user's request water consumption.
Cistern water supply pattern includes：
Step 3, when the pressure value that first pressure sensor detects be less than P3 when, or, when first pressure sensor inspection
When the pressure value measuring reaches setting duration in the range of between P1 and P2, valve auto-alternate to cistern water supply, water pump is taken out
Water in water tank is supplied water, and controller controls pump operation so that the pressure value that second pressure sensor detects is equal to
The P4 or P4 that levels off to.Specifically, when the pressure of city planting ductwork is less than P3, city planting ductwork cannot continue to provide water source, now, control
Control valve is switched to device processed cistern water supply so that the pressure value that second pressure sensor detects is equal to P4 or levels off to
P4, thus extend user uses the water time, realizes continuing to supply water in the case that city planting ductwork is cut off the water supply；Likewise, when the first pressure
When the pressure value that force transducer detects reaches setting duration in the range of between P1 and P2, the output of city planting ductwork is described
The requirement of user side water consumption cannot be met for a long time, by impact user side use regimen condition, now, be also converted into water tank supply
Water, to guarantee the water demand of user side.
When the storage time of the water in step 4, water tank reaches setting duration, valve auto-alternate to cistern water supply, municipal administration
Water in pipe network is flowed in water tank, and the water that water pump extracts in water tank is supplied water.Specifically, in order to avoid occurring in water tank
Water storage time is long and rotten, and in the case that the pressure of city planting ductwork is in output abundance more than P1, controller will be
The time control valve action setting, is switched to cistern water supply, and the water in city planting ductwork will add in water tank so that water tank
Interior water periodically consume, circulate, it is to avoid the water occurring in case does not use and mouldy situation for a long time.Under normal circumstances, in water tank
Be provided with liquidometer, by liquidometer control water tank water level be located at rational scope in, when the water level in water tank reach minimum
Or during peak level, valve will switch back into city planting ductwork and supply water.
Wherein, P1 is the minimum operating pressure value of city planting ductwork（The minimum pressure that pipe network allows in the case of carrying out water yield abundance
Value）, P2 is city planting ductwork self-balancing pressure value（Substantially meet city planting ductwork output and reach identical shape with pumping for water pump amount
State, generally little compared with P1 value 0.02MPa-0.05 MPa）, P3 is the minimum safe pressure value of city planting ductwork, and P4 is specified water outlet pressure
