Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, the present invention is that one one drags many constant pressure water supply systems, comprise power supply 1, pressure sensor 2, also comprise frequency converter 3, control circuit 4 and water supply installation, power supply 1 connects frequency converter 3, pressure sensor 2 is located on pipeline 5, pressure sensor 2 is connected with frequency converter 3, and frequency converter 3 is connected with control circuit 4, and frequency converter 3 is connected with several water supply installation, water supply installation comprises water pump and the A.C. contactor assembly of series connection, and A.C. contactor assembly is formed in parallel by two A.C. contactors.
Frequency converter 3 is SY9000 frequency converter.SY9000 frequency converter is core component, and according to pipeline 5 pressure size, Based Intelligent Control one drags many constant pressure water supply systems; Pressure sensor 2: testing pipes 5 pressure, and pressure size is converted to the signal of telecommunication sends SY9000 frequency converter to; Control circuit 4: accept the control signal that SY9000 frequency converter is sent, the disconnection controlling A.C. contactor closes; Water pump: supply water; A.C. contactor: on-off controls water pump.
Water supply installation is provided with three, namely water pump is provided with three, be respectively the first water pump (hereinafter referred to as M1), second water pump (hereinafter referred to as M2) and the 3rd water pump (hereinafter referred to as M3), A.C. contactor assembly is provided with three covers, be respectively the first A.C. contactor assembly, second A.C. contactor assembly and the 3rd A.C. contactor assembly, described first A.C. contactor assembly is by the first A.C. contactor (hereinafter referred to as KM1), second A.C. contactor (hereinafter referred to as KM2) is formed in parallel, described second A.C. contactor assembly is by the 3rd A.C. contactor (hereinafter referred to as KM3), 4th A.C. contactor (hereinafter referred to as KM4) is formed in parallel, described 3rd A.C. contactor assembly is by the 5th A.C. contactor (hereinafter referred to as KM5), 6th A.C. contactor (hereinafter referred to as KM6) is formed in parallel.
System obtain electric after, KM1 ~ KM6 is in off-state, and M1, M2, M3 are in stopped status.Now inside pipeline 5, pressure is zero, if be just in time now user's water use peak, pressure sensor 2 delivers to SY9000 frequency converter after pipeline 5 pressure signal being detected, SY9000 frequency converter outputs signal according to after this pressure signal analysis, KM1 adhesive is made through control circuit 4, thus make M1 obtain electric operation, enter independent variable frequency work state, running speed progressively increases from low to high.Along with the running of M1, pipeline 5 pressure progressively rises, pressure sensor 2 Real-Time Monitoring pipeline 5 pressure, and SY9000 frequency converter changes output frequency in real time thus changes motor speed, until arrive the pipeline pressure of user's setting.Now system is in variable frequency work state.
When motor speed is raised to the highest, still do not arrive the pipeline pressure of user's setting, at this time SY9000 frequency converter sends instruction successively, and disconnect KM1, adhesive KM2, adhesive KM3, thus make M1 enter power frequency duty, M2 enters variable frequency work state.Now system is in the state of the work of M1 power frequency, M2 variable frequency work.
When motor speed is raised to again the highest, still do not arrive the pipeline pressure of user's setting, at this time SY9000 frequency converter sends instruction successively, and disconnect KM3, adhesive KM4, adhesive KM5, thus make M2 enter power frequency duty, M3 enters variable frequency work state.Now system is in the state of the work of M1, M2 power frequency, M3 variable frequency work.
Otherwise if evening, user's water supply volume reduces, and pipeline pressure increases, and exceeded user's setup pressure value, then system is in and subtracts pump state.According to the principle of first at first stopping when subtracting pump, be first that M3 rotating speed reduces, when low still too large to minimum pressure, at this time SY9000 frequency converter sends instruction, disconnects KM2,
Close M1 water pump, make system be in the work of M2 power frequency, M3 variable frequency work state, M1 water pump quits work.SY9000 frequency converter adjusts M3 pump rotary speed in real time according to pipeline pressure, if pressure is still too large, M3 pump rotary speed has dropped to minimum again also to can not meet requirement, now, SY9000 frequency converter sends instruction, disconnects KM4, close M2, make system be in independent frequency conversion state, i.e. M3 variable frequency work, M1, M2 quit work.SY9000 frequency converter continues adjustment M3 pump rotary speed according to pipeline pressure, if pressure is still too large, M3 pump rotary speed has dropped to minimum again also to can not meet requirement, and now, SY9000 frequency converter enters resting state, quits work.Now all motors of system enter stopped status.
The above be of starting for M1 motor complete add pump subtract pump circulation, in real work, not necessarily circulate from M1 motor, perhaps from M2 or M3 motor, but its add pump to subtract pump work process same as described above, operating principle is also identical, so also need to arrange KM6.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
