The utility model discloses the theory of operation and the process of system's device (use the water supply main pump to be 3 the utility model discloses the system is the example).
When the water consumption is lower than the water supply amount of one pump, the system only starts and operates the variable frequency pump No. 1, constant-pressure variable water supply is carried out, the pressure of a pipe network is kept constant, when the water consumption is increased, the variable frequency pump rapidly reacts to increase the frequency until the power frequency reaches 50Hz, if the water consumption requirement cannot be met at the moment, 30 seconds (the time can be set randomly) are delayed, the system immediately circularly starts the power frequency pump No. 2 through the frequency converter (after the circular start of the frequency converter, the original variable frequency pump No. 1 is switched into the power frequency pump, the original power frequency pump No. 2 is switched into the variable frequency pump, and the pump No. 3 is standby and standby), at the moment, the frequency of the variable frequency pump automatically rises or falls until the water consumption requirement is just met, so that the pressure of the pipe network is always kept constant; if still can not satisfy the water requirement this moment, delay 30 seconds (the time can be set for wantonly), this system immediately through the converter cycle start 3 power frequency pumps (through this converter cycle start back, former 2 number frequency conversion pumps switch into the power frequency pump, former 3 number power frequency pumps then switch into the frequency conversion pump, 1 number pump standby is reserve), the frequency conversion pump frequency automatic rising or descend just satisfies the water requirement this moment, analogize with this to maintain pipe network pressure steady all the time.
The special pipe network self-diagnosis protection function of the 'Jiahao' green intelligent box type non-negative pressure water supply man-machine interface control system avoids major property loss caused by pipe explosion of municipal administration and user pipe networks. When the municipal pipe network is under-voltage or pipe burst, the system is immediately protected to shut down, the municipal pipe network pressure is not influenced, and the damage to the water pump and the energy waste caused by dry grinding of a system unit are avoided. When the municipal pipe network pressure recovers to be normal, the system automatically starts to operate immediately to recover normal water supply; when the pipe burst of the user pipe network occurs, the system is immediately protected to shut down, thereby not only protecting the unit from being damaged due to excessive abrasion, but also avoiding flood caused by supplying a large amount of tap water, saving energy and water, and protecting the property of the owner from being lost!
When the municipal pipe network is lack of water supply and the pressure is reduced to 1.0 kg (the pressure can be set according to the actual conditions of local tap water companies) or the municipal pipe network stops water supply, the control system immediately starts the box type booster pump to pressurize the stored water (0 pressure) in the water tank to the steady flow balancer, so that the water supply pressure in the steady flow balancer always keeps normal municipal pipe network pressure, and the situation that the water supply unit needs to be shut down protectively due to insufficient water supply of the municipal pipe network can be avoided, thereby ensuring the continuity of water supply of users;
when the municipal pipe network pressure recovers to be normal, the control system controls the box type booster pump to automatically stop, and the water supply system completely recovers to a non-negative pressure water supply mode.
If the municipal pressure is always stable, in order to ensure that the water quality of the water tank is not changed, the system can regularly and forcibly switch the non-negative pressure water supply mode to the box type variable frequency water supply mode, so that the stored water in the water tank is regularly replaced, and the water quality of the stored water in the water tank is ensured; and after the running time of the box type water supply mode reaches the set running time, the system can forcibly switch the box type variable frequency water supply mode to the non-negative pressure water supply mode.
