The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As seen from Figure 2: the present invention includes water pump assembly (5,6,7), inlet pipeline 1, user's pipe network 14, outlet header road 10, the first control instrument 11, the second control instruments, 12, the three control instruments 13 and the switch board 15 that links to each other with described three control instruments; Described water pump assembly (5,6,7) comprises first water pump 5 and second water pump 6 and the 3rd water pump 7; Also comprise 8, one air pressure tanks 4 of 2, one non retern valves of a flap valve; One end of described flap valve 2 water inlets links to each other with municipal water sources, one end of flap valve 2 water inlets also links to each other with the entrance pipe of the 3rd water pump 7, flap valve 2 delivery ports link to each other with air pressure tank 4, and flap valve 2 delivery ports also link to each other with the entrance pipe of first water pump 5, second water pump 6; The water inlet of described non retern valve 8 links to each other with the export pipeline of the 3rd water pump 7, and the entrance pipe of the delivery port of non retern valve 8 and air pressure tank 4 and first water pump 5 and second water pump 6 also connects;
The power of described first water pump 5 and second water pump 6 is greater than the 3rd water pump 7.
The air pressure tank effect: the water under high pressure that air pressure tank is stored during zero delivery leads to the equipment outlet through first water pump 5, realizes the shutdown pressure holding function of equipment; Air pressure tank moisturizing energy storage is given in the operation of pump the 3rd water pump 7 during low discharge, pump first water pump 5,6 operations of second water pump during big flow, and the water under high pressure that air pressure tank is stored is also as one of water source, is used for realizing the peak clipping compensating action to municipal water supply.Electric the going up that be implemented in of above function adopted time division multiplex control, leans on the pipeline connecting mode of air pressure tank 4, flap valve 2, non retern valve 8 and water pump assembly on pipeline structure of the present invention.
The present invention is not limited to 7 one on the 3rd water pump according to the equipment configuration with the water pump that water inlet one side of the needs flap valve 2 of the method for operation is connected, and the water pump that flap valve 2 delivery ports one side connects is not limited to 6 two on first water pump 5, second water pump.
The signal that switch board 15 is gathered according to control first control instrument 11, the second control instruments 12, the three control instruments 13 is implemented control to the operation of equipment.In order effectively to utilize the original pressure potential of municipal water sources, also for adapting to significantly variable parameter operation of water pump, feed pump first water pump 5, second water pump 6, the 3rd water pump 7 all should adopt variable frequency regulating speed control simultaneously.
Three pumps are by 2 big 1 little considerations, and big pump first water pump 5 and second water pump, 6 alternate runs are standby each other, and the 3rd water pump 7 is as the low discharge process pump.Operation control method of the present invention is as follows: the equipment of the normal operation of debugging, the hydraulic pressure that keeps user's pipe network 14 between down period by air pressure tank 4, when the air pressure tank energy storage is used consumption, make when user's pipe network water pressure is reduced to the low pressure limit of setting, equipment starts operation automatically, what at first start is low-capacity pump the 3rd water pump 7, this pump directly extracts municipal water sources, at original pressure-based up-conversion speed governing operation, difference what mend how much realize energy-saving run, one side constant pressure water supply demand in the outlet header satisfies the single pump low discharge of user scope can be given the air pressure tank moisturizing through non retern valve 8 on the other hand during this pump operation, make air pressure tank be in higher energy storage state; If user's pipe network water supply volume increases; 7 operations of low discharge feed pump the 3rd water pump can not satisfy the demands; then start big pump first water pump 5 of feedwater or 6 operations of second water pump automatically; while low-capacity pump the 3rd water pump 7 time-delay autostops; when feed pump first water pump 5 or 6 operations of second water pump; because the high pressure water storage in the air pressure tank is also as one of water source, thereby municipal water supply is had certain peak compensating action, compare the sort buffer compensating action with existing equipment and need not set up switching device shifter.When a pump first water pump 5 or the operation of second water pump 6 can not be satisfied traffic demand, first water pump 5 and 6 operations of second water pump can automatic parallel operations.The big flow run duration of the present invention is forbidden operation with autostop, to avoid the excessive suction to municipal water sources during as the minimum swabbing pressure that water inlet manifold place pressure occurs and allow smaller or equal to municipal water sources.If run duration user pipe network water supply volume of the present invention reduces, so that make the feed pump running frequency low excessively, then can subtract pump automatically, when subtracting when getting back to 7 operations of low-capacity pump the 3rd water pump, can give air pressure tank moisturizing energy storage by the pipeline of non retern valve 8 again.During 7 isolated operations of rill flow control three water pumps; reduce to very low or be 0 o'clock as user's pipe network water supply volume; the present invention will enter stopping process automatically: the 3rd water pump 7 can quicken operation autostop after the upper pressure limit of being pressurized to setting for the air pressure tank water-filling automatically; also be equipment downtime, the effect of air pressure tank at this moment becomes the pressurize effect of shutting down again.
