automatic air intake-exhaust valve 11 exhaust airs by tap water, closes automatically water must not outwards be flowed out.Normal as hydraulic pressure, equipment need not start, but normal water supply.
Have only 2 kilograms as actual tap water pressure, (0.2MPa) user is 4.5 kilograms of the required hydraulic pressure of 10 floors, and (0.45MPa) at this moment hydraulic pressure is obviously not enough.In order to solve these water requirements, closed fully-automatic constant pressure of the present invention, voltage stabilizing variable energy-saving water supply equipment is only better environment-friendly type automatic water supply device.
Use the present device operating principle, see schematic diagram 1 for details, example of the present invention is described.
During as tap water actual pressure (0.2MPa), the actual required hydraulic pressure 0.45MPa of user could satisfy, and uses the operating principle of present device to be: according to the actual required hydraulic pressure of user, set pressure of supply water.According to the maximum hourly consumption of user peak period, select the equipment output.The user selects your needed supply equipment according to the output and the pressure of supply water of equipment, just can satisfy your best result of use.Example: certain user is 10 floors, and both life and fire fighting purposes needs total consumption 35m3/n (per hour 35 tons of water) anthology invention equipment three pump assemblys of pressure of supply water 0.5MPa (5 kilograms of pressure) one cover.Water supply flow is 36m3/n.Satisfy greater than 35m3/n.Pressure of supply water 0.55MPa (5.5 kilograms) satisfies greater than 0.5MPa.Choice of equipment is correct.According to schematic diagram 1 explanation, the present device example begins normally to use its operating principle to be: when pressure of supply water is not enough, by the pressure signal that pressure sensor 51 is surveyed, pass to controller 48, electric-motor pump 25 is carried out soft speed governing operation.Prestart should be opened the gate valve of intake gate plate valve 23 and three pump groups.At this moment water is in slide valve 23 enters flexible joint 24 electric-motor pumps 25, after the water pump pressurization, entering flexible joint 24 and damping check valve 29 and exit branch 30 enters total feed pipe 17 and regulates through the water supply gate valve, actual required pressure in the system water supply house steward 19 is guaranteed normal water supply to life water for fire point 20.When system's total water amount increased, pressure sensor 51 recorded pressure signal and passes to the public running frequently of 48 pairs of electric-motor pumps of controller, 25 dos.(frequency is 50HZ) actuating motor pump 26 simultaneously carries out soft speed governing operation.Its pressurization flowchart process is identical with electric-motor pump 25.When system's total water amount in the peak water phase, when the total water amount increased to maximum, pressure sensor 51 recorded pressure signal, passed to controller 48 (early, middle and late and phase festivals or holidays), and electric-motor pump 26 is done public running frequently.Actuating motor pump 27 carries out soft speed governing operation simultaneously.Its pressurization flowchart process and electric-motor pump 25, electric-motor pump 26 are identical.Satisfy system's peak period water supply volume.
When the system water amount reduces, increased pressure, pressure sensor 51 records pressure signal, passes to controller 48 and stops electric-motor pump 25.At this moment damping check valve 29 is closed automatically, has prevented the water under high pressure refluence, and when the system water amount reduced again, pressure increased again, and pressure sensor 51 records signal, passes to controller 48 and stops electric-motor pump 26 its damping check valves 29 and close automatically.When the system water amount is very little, and night not during water, hydraulic pressure increases, and pressure sensor 51 records signal, passes to 48 pairs of electric-motor pumps of controller 27 and carries out reduction of speed, frequency reducing work.When frequency was reduced to minimum setting value, electric-motor pump 27 stopped voluntarily.Its damping check valve 29 is also closed voluntarily.When shutting down; the water hammer power that the downward freely falling body of water in the water system is produced; import total feed pipe 17 into through system water supply house steward 19; because each closure of check ring; water hammer power enters in the energy storage jar body 37 from water inlet pipe and water outlet pipe joint 31; owing in jar air is arranged, inflatable and compression could effectively be eliminated water hammer power and is no longer produced noise.The water hammer power of utilizing the water hammer ripple to be produced is simultaneously carried out automatic tonifying Qi.Strengthen the air compression ratio in the energy storage jar, improved shutdown pressurize energy storage economize on electricity water supply effect.Comparing with other air pressure tank is three to five times.Can change simultaneously the evil of water hammer power, supply water to sharp,, not produce pollution, eliminate water noise again because of this air supply tank adopts steel structure material production entirely for tonifying Qi pressurize economize on electricity, from and prolonged application life of water system facility.It is existing all kinds of air pressure tanks incomparable effect far away.
Energy-conservation energy storage water-hammer arrester of the present invention and automatic tonifying Qi operating principle constant voltage type are: set constant pressure value is detected by pressure sensor 47 in energy storage jar body 37.Deficency whether in the energy storage jar body 37 needs to replenish, and is detected by constant voltage sensor 52, need not tonifying Qi in the jar when constant voltage sensor 52 detection heads are in gas.The intrinsic constant pressure value of energy storage jar is to decide according to the user's request force value, is set and is controlled by automatic tonifying Qi controller 50.When constant voltage sensor 52 during by water logging, a deficency needs make-up gas in jar, and at this moment constant voltage sensor 52 sends signal, passes to automatic tonifying Qi controller 50, is opened automatically by controller, and electromagnetic valve 44 is started working.Water under high pressure in the energy storage jar body 37 enters connecting leg 40 through water-water jet and enters water-water jet body 42 and be discharged to total feedwater connecting leg 21 and filter in the ballast through tonifying Qi draining connecting leg 45 and drainage check valve 49 through electromagnetic valve 44.At this moment the water in the water-water jet 42 forms torrent and makes place, water-water jet 42 inner nozzle chambeies build-up of pressure poor, and the water in the tonifying Qi chamber 38 flows in the water-water jet body 42 through suction connecting leg 43 and to be pulled away under the effect of earth attraction.Air enters breather check valve 33 in air inlet connecting leg 34 enters tonifying Qi chamber 38 from air filter 32, when the indoor water of tonifying Qi has been pulled away, (test setting-up time), tonifying Qi controller 50 is closed electromagnetic valve 44 automatically.At this moment the water in the energy storage jar body 37 is subjected to enter water-water jet body 42 from water-water jet water inlet connecting leg 40 under the active force of water hammer power in the system and hydrostatic pressure and pump head, enters in the tonifying Qi chamber 38 through suction connecting leg 43.Be subjected to high pressure from bottom to top with the air in the tonifying Qi chamber 38, enter charging check valve 35 through air inlet connecting leg 34, inflation connecting leg 36 with gas pressurized in energy storage jar body 37.One time the tonifying Qi process promptly comes to an end.After constant voltage sensor 52 all surfaces, just can stop inflation.Whole automatic tonifying Qi process is finished by automatic tonifying Qi controller 50 auto-controls.
The energy-conservation energy storage water-hammer arrester of voltage regulation type of the present invention operating principle: its principal character is: when the pressure of pressure sensor 47 detections drops to the low pressure of setting, voltage stabilizing sensor 46 as when all exposing water, send signal and remember for automatic tonifying Qi controller 50, do not need tonifying Qi in the energy storage jar body 37.When not had by water logging, send signal and remember for automatic tonifying Qi controller 50 as voltage stabilizing sensor 46.Deficency in the energy storage jar body 37 needs inflation.Etc. next energy storage jar body 37 internal pressures, measure through pressure sensor 47.When dropping to minimum setup pressure value, tonifying Qi controller 50 sends control signal and opens electromagnetic valve 44 work automatically automatically, carries out tonifying Qi.The tonifying Qi process is identical with the constant voltage type.Its voltage regulation type tonifying Qi feature is: only whether need the memory of tonifying Qi for the first time.By the time for the second time in the energy storage jar body 37 and system pressure when dropping to minimum setup pressure value, by automatic tonifying Qi controller 50 according to the memory decision.As need not tonifying Qi, just do not open electromagnetic valve 44, as the needs tonifying Qi, just open electromagnetic valve 44 and carry out the work tonifying Qi.Its tonifying Qi time is only limited at setting minimum pressure test point carries out tonifying Qi.All the other phenomenon times must not tonifying Qi.Whole tonifying Qi process is controlled voluntarily by automatic tonifying Qi controller 50 and is finished.
The main effect of the energy-conservation energy storage water-hammer arrester of the present invention is: eliminate the pipe network system water hammer, shut down the pressurize energy storage and supply water.After the electric-motor pump of native system all stops, by the gas in the energy storage jar body 37 after step-down and expand, the water in the energy storage jar body 37, be pressed onto total feed pipe 17 and system water supply house steward 19 to life water for fire point 20 maintenances water supply continuously through water inlet pipe and water outlet pipe joint 31.Realized at low discharge and can shut down the effect that pressurize is supplied water and not consumed energy night.When the system water amount increased, the system pipe network internal pressure descended, and records signal by pressure sensor 51, passes to 48 pairs of electric-motor pumps of controller 25 and carries out soft speed governing operation.When water source supply deficiency and tap water cut-off; drawdown in the ballast body 9; air under atmospheric pressure enters drawdown in the ballast body 9 to water source electrode 12 when following from automatic air inlet, outlet valve 11; electrode sends the lack of water signal and stops for controller 48 water pumps automatically, enters guard mode.After having abundant water resources, after the water source electrode 12 in the ballast body 9 is not had by water logging, after 10 minutes, automatically terminate protection, equipment is normal water supply voluntarily.
