reach the required specified hydraulic pressure value of user and not during water; system pipe network hydraulic pressure increases; when surpassing specified hydraulic pressure value; pressure gauge sensor 28 is passed to controller 29 with signal; controller control of pump 6 is shut down, and shutting down the back is provided by hydraulic pressure energy storage jar 26 and press potential energy to keep hydraulic pressure in the water supply network.When hydraulic pressure is reduced to the specified hydraulic pressure value of low level, by pressure sensor 28 signal is passed to controller 29, control of pump 6 starts.Supplying water in servicely,, with the variation of day hourly consumption, adopting different flow respectively, the water pump that lift is identical according to user's day maximum water supply volume and per day water supply volume.Satisfy the output in the different time respectively as A, B, C pump.System's peak water supply volume reaches maximum especially water supply volume, equals the flow of A+B+C pump.Adopt A, B, many pressure sensors of C and controller to control many water pumps respectively respectively.When establishing many pumps, but its operation working programme Automatic Cycle operation.When system water, when pressure dropped to the specified starting pressure of C pump, pressure sensor was passed to the C pump controller with signal, and control C pump starts voluntarily.When water supply volume continue to increase, when making system pressure drop to the specified starting pressure of B pump, B pump sensor is passed to the B pump controller with signal, and control B pump starts voluntarily.When water supply volume continues to increase again, make and depress when dropping to the specified starting pressure of A pump, the A pump pressure sensor is passed to the A pump with signal and is started voluntarily.When system's peak maximum water supply volume, A, B, three pumps of C move simultaneously.When the system water amount reduced, when increased pressure arrived C pump rated high voltage value, the C pump pressure sensor was passed to the C controller with signal, control C pump self-stopping.When water supply volume continued to reduce, when increased pressure arrived B pump rated high voltage value, the B pump pressure sensor was passed to the B pump controller with signal, control B pump self-stopping.When water supply volume continued to reduce again, when increased pressure arrived A pump rated high voltage value, the A pump pressure sensor was passed to the A pump controller with signal, and control A pump is shut down from machine.After system pipe network moves a period of time,, taken away by water because a jar interior part air is dissolved in the water.Air pressure in making jar is than reducing, and the potential energy in jar also reduces thereupon, and at this moment during the equipment downtime minimum pressure, the gas in jar can not be compressed to the water level in the jar low water stage and detect mouthfuls 13 o'clock, proves a jar interior deficency.At this moment low water stage detects mouthfuls 13 signal is passed to controller, signal is memorized, Deng water pump operation when the high pressure spot, controller 29 sends signal, electromagnetic valve 17 is opened (time is to set according to the volume size of air supply tank) in 15 seconds～1 minute, make the water under high pressure of system pipe network enter water-water jet 15 through water filling connecting leg 14, because high velocity jet, make the interior build-up of pressure of water-water jet poor, with the water in the air supply tank 19, bring in the water-water jet 15 through suction connecting leg 16, through electromagnetic valve 17, sluicing connecting leg 18 enters in the pump entrance strainer.At this moment, cause Negative Pressure Difference in the air supply tank 19, atmosphere enters in the air supply tank 19 through silencer-filter 22, air back valve 21, three connecting pipes 20.Behind the air supply tank gassy, simultaneously also be water in the air supply tank when being blotted, electromagnetic valve 17 cuts out in setting-up time automatically.At this moment the gas in the air supply tank 19 is subjected to the effect of pump head and system pipe network hydrostatic pressure; water under high pressure is through water filling connecting leg 14; through water-water jet 15, suction connecting leg 16; enter in the air supply tank 19; gas is from bottom to top passed through threeway 20, blowdown pipe movable joint 23, tonifying Qi flap valve 24, blowdown pipe seated connection head 25 in jar; be expressed to middle and upper part in the hydraulic pressure energy storage jar 26, gas is added in the jar at any time, guarantee to shut down the effect of pressurize.When the water source interrupts, detect interface 4 by the water source, signal is passed to electronic controller 29, control of pump 6 is shut down.This equipment water-supply voltage-stabilizing energy storage and startup and shutdown and automatic gas compensation function ensure fully automatic working by detection system interface and electronic controller coordination.

Embodiment 2 (Fig. 4): on the basis of embodiment 1, with draining connecting leg 18, electromagnetic valve or motor operated valve 17, water-water jet 15 (prior art), water filling connecting leg 14 usefulness pumps suck connecting leg 32, tonifying Qi motor and water pump 33, air supplying pump outlet connecting leg 34 replaces, its structure design: air supply tank (19) adopts air supply tank pony sill (31) to be installed on the plant bottom case (30), the lower end outlet of air supply tank (19) adopts pump suction connecting leg (32) to be communicated with the water inlet of tonifying Qi motor and water pump (33), and the delivery port of tonifying Qi motor and water pump exports connecting leg (34) and total water outlet connecting leg (11) and hydraulic pressure energy storage jar (26) through air supplying pump and is communicated with.Operating principle.The agent structure of this equipment complete machine is identical with the voltage regulation type structure.This equipment is after system moves a period of time, soluble in water for part air in the jar, taken away by water, a jar interior gas compression ratio is reduced, at this moment jar interior potential energy reduces, water level in the energy storage jar rises to high water level and detects mouth 9 o'clock, proof jar interior deficency, at this moment detect mouthfuls 9 signal passed to electronic controller 29, control tonifying Qi motor and water pump 33 starts, water in the air supply tank 19 is sucked connecting leg 32 through pump, be extracted into air supplying pump outlet connecting leg 1 by tonifying Qi motor and water pump 33, in the total water outlet connecting leg 11 of access arrangement.At this moment the water in the air supply tank is taken away, and build-up of pressure is poor in jar, and air enters through air back valve 21 from strainer 22, enters in the air supply tank 19.The tonifying Qi motor and water pump is shut down in setting-up time.Water in the air supply tank 19 is also drained simultaneously.At this moment intrasystem water under high pressure, through pump discharge connecting leg 1, tonifying Qi motor and water pump 33, pump sucks connecting leg 32, from bottom to top enters in the air supply tank 19.Gas in the jar through flap valve 8, is expressed in the middle and upper part of hydraulic pressure energy storage jar 26.Gas can be added in the hydraulic pressure energy storage jar 26 at any time, guarantee the effect of energy storage constant voltage.This tonifying Qi mode is more reliable than any tonifying Qi mode.But because its cost height, in being mainly used in, in the large-scale complete pumping plant supply equipment structure.

Embodiment 3: on the basis of embodiment 2, be provided with pump interface more than a jar (12) on total water outlet connecting leg (11), purpose is to realize one jar of two pump or one jar of three pump or one jar of four pump ...
