Beneficial effect: in this many pump frequency conversions control system based on motor control, the force value of press detection sensor Real-time Collection outlet conduit also feeds back in controller, each water pump is individually by each Frequency Converter Control, when detecting that water consumption is the biggest, the first converter, the second converter and the 3rd converter can be started simultaneously and carry out variable frequency adjustment water supply；When water consumption is little and changes little, a wherein converter is only activated individually and carries out variable frequency adjustment water supply, thus reach accurately to control and be effectively improved the purpose of water pump efficiency.
Accompanying drawing explanation
With embodiment, this utility model is described further below in conjunction with the accompanying drawings；
Fig. 1 is the systematic schematic diagram of this utility model embodiment.
Detailed description of the invention
With reference to Fig. 1, a kind of many pump frequency conversions control system controlled based on motor of this utility model, including outlet conduit 10 and the water pump assembly 20 that is connected with outlet conduit 10, water pump assembly 20 includes the first water pump 21 being arranged in parallel, second water pump 22 and the 3rd water pump 23, first water pump 21, second water pump 22 and the 3rd water pump 23 have been connected respectively the first converter 24, second converter 25 and the 3rd converter 26, first converter 24, second converter 25 and the 3rd converter 26 are connected with a controller 30, outlet conduit 10 is provided with the press detection sensor 11 being connected with controller 30.
Wherein, press detection sensor 11 detects the pressure of supply water of waterpipe 10, and Real-time Feedback is in controller 30, when detecting that water consumption is the biggest, starts first converter the 24, second converter 25 simultaneously and the 3rd converter 26 carries out variable frequency adjustment water supply；When water consumption is little and changes little, a wherein converter can be only activated individually and carries out variable frequency adjustment water supply, thus reach accurately to control and be effectively improved the purpose of water pump efficiency.
Wherein, this many pump frequency conversions control system also includes steady-flow tank 40 and the water tank 50 being arranged in parallel, steady-flow tank 40 is connected with tap water inlet channel 60 respectively with the water inlet port of water tank 50, steady-flow tank 40 is connected with water pump assembly 20 respectively with the water outlet port of water tank 50, the 50 water inlet ports at water tank are provided with, at water outlet port, the water intaking valve 51 and outlet valve 52 being connected with controller 30 respectively, the level sensor 53 being connected with controller 30 it is provided with in water tank 50, the outlet valve 52 being connected with controller 30 it is provided with in the water outlet port of steady-flow tank 40, the aux. pressure detection sensor 41 being connected with controller 30 it is provided with in steady-flow tank 40, water intaking valve 51 and outlet valve 52 are controlled to open or close by controller 30.
Steady-flow tank 40 and water tank 50 are arranged in parallel and supply water for water pump assembly 20, specific as follows, when carrying out normal water supply, tap water inlet channel 60 directly provides water source, and after steady-flow tank 40, water pump assembly 20 add and press to outlet conduit 10 and supply, now, the outlet valve 52 of the water outlet port of water tank 50 is to close, and water tank 50 is as alternate source.When the inflow of tap water inlet channel 60 is not enough or cuts off the water; when the intake pressure detected by the aux. pressure detection sensor 41 in steady-flow tank 40 is less than the voltage limiting value set; the outlet valve 52 of the water outlet port of steady-flow tank 40 is closed; the outlet valve 52 of the water outlet port of water tank 50 is opened; water source is provided for water pump assembly 20 by water tank 50; thus avoid water pump assembly 20 because of anhydrous and stoppage protection, it is ensured that normal water supply.When the aux. pressure detection sensor 41 in steady-flow tank 40 detects that force value is recovered to setup pressure value, the outlet valve 52 of the water outlet port of steady-flow tank 40 is opened, the outlet valve 52 of the water outlet port of water tank 50 is closed, it is provided with setting-out source through steady-flow tank 40 for water pump assembly 20 by tap water inlet channel 60, recovers normal water supply.
As preferably, outlet conduit 10 is also associated with air pressure tank 12, when water consumption reduces, the water redundance that water pump assembly 20 is got enters into air pressure tank 12 and stores, when air pressure tank 12 water storage reaches design pressure, water pump assembly 20 is out of service, and at this moment user turns and laid in water by air pressure tank 12 and meet and use, and reaches to improve water pump efficiency and energy-conservation purpose with this.
Above in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to above-mentioned embodiment, in the ken that described technical field those of ordinary skill is possessed, it is also possible on the premise of without departing from this utility model objective, various changes can be made.
