Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
The structure of a kind of small-sized intelligent domestic deep-well constant pressure water supply system of the present utility model as depicted in figs. 1 and 2, comprises for weed buffer 6, air pressure tank 7, filter 5, and well pump water inlet system and control system;
Described well pump water inlet system is used for shaft bottom and draws water and the water be extracted into is delivered to described filter 5; Water after described filter 5 filters is delivered to described for weed buffer 6 and described air pressure tank 7 successively; Described is a container for weed buffer 6, the described weed buffer 6 that supplies is built with water, the upper end of described water is provided with the gas being in air-tight state, and described weed buffer 6 upper end that supplies is provided with pressure sensor 10, and described pressure sensor 10 is for detecting the described pressure for gas in weed buffer 6; The work of well pump water inlet system described in the Numerical Control that described control system detects according to described pressure sensor 10.
Wherein, described well pump water inlet system comprises deep well pump 1, backflow preventer 3 and butterfly valve 4, described backflow preventer 3 and butterfly valve 4 are arranged on the outlet conduit of described deep well pump 1, described deep well pump 1 has two, described two deep well pumps 1 are in parallel to be also connected with frequency converter respectively, and described two deep well pumps 1 connect mode and adopt intercoupling type.
If deep well pump 1 breaks down, transmit deep well pump fault-signal by sensor to control system, after control system receives fault-signal, judge, make fault deep well pump 1 out of service, start another deep well pump 1 simultaneously.These two deep well pumps 1 adopt mutual coupling to be connected with frequency converter, can not use simultaneously, a job, and other one does not work.
In the present embodiment, described water supply surge tank 6, air pressure tank 7 and filter 5 are arranged on a falsework 9.
In the present embodiment, described control system comprises changeable water supply controller and frequency converter, and described changeable water supply controller is programmable logic controller (PLC) 8, and described frequency converter is used for the power supply of described well pump water inlet system; Described programmable logic controller (PLC) 8 receives numerical value that described pressure sensor 10 detects and controls described frequency converter work by following logical course: the numerical value detected when described pressure sensor 10 is less than preset value, then programmable logic controller (PLC) 8 controls described frequency converter and increases electric current output frequency; The numerical value detected when described pressure sensor 20 is greater than preset value, then programmable logic controller (PLC) 8 controls described frequency converter reduction electric current output frequency.
During work, what pressure sensor 10 was in good time passes to programmable logic controller (PLC) 8 by for the pressure of gas in weed buffer, gas pressure and setting value compare by programmable logic controller (PLC) 8, determine the rotating speed of deep well pump 1, to keep stablizing for gas pressure in weed buffer 6, if be less than set-point, programmable logic controller (PLC) 8 sends signal to frequency converter, after frequency converter receives the signal of programmable logic controller (PLC) 8, frequency converter makes the frequency of output current increase, thus the rotating speed of deep well pump 1 is increased, the water yield of deep well pump 1 increases.Now, setting pressure is reached for weed buffer 6 pressure; If be greater than set-point, described programmable logic controller (PLC) 8 sends signal to frequency converter, and after frequency converter receives the signal of programmable logic controller (PLC) 9, frequency converter makes the frequency decrease of output current, thus the rotating speed of deep well pump 1 is declined, the water yield of deep well pump 1 reduces; If equal set-point, described programmable logic controller (PLC) 8 sends signal to frequency converter, and after frequency converter receives the signal of described programmable logic controller (PLC) 8, frequency converter makes the frequency of output current constant, thus making deep well pump 1 running speed constant, the water yield of deep well pump 1 is constant.When gas pressure in confession weed buffer 6 is very unstable or gas pressure still can not be made to be stabilized to setting value after unlatching deep well pump 1, beating for weed buffer 6 pressure sensor may well be that well liquid level is too low in water pipe network, then programmable logic controller (PLC) 8 can make deep well pump 1 out of service.
During water usage at night reduces, water supply end pressure sensor 14 is greater than setting pressure, water supply end pressure 14 setup pressure value is 1.5 times of the setting value of pressure sensor 10, deep well pump 1 enters resting state automatically, supplied water directly to user by pipe network, during insufficient water, deep well pump 1 automatically resumes operation under the regulation and control of programmable logic controller (PLC) 8.When user without water or water supply volume very little time; equipment enters shutdown resting state automatically; the electromagnetic valve 11 opening air pressure tank maintains number of users water and pipe network water leakage by the low discharge air pressure tank 7 being located at the parallel connection of equipment water outlet side; when user can not maintain pressure needed for water supply network with water pressure tank, water supply surge tank pressure sensor 10 arrives lower limit, and equipment wakes up automatically; recover normal to run; air pressure tank 7 carries out moisturizing, and air pressure tank pressure sensor 12 arrives setup pressure value, and electromagnetic valve 11 cuts out.Make full use of the surplus pressure of tap water pipe network in equipment running process, neither cause adverse effect to meet consumers' demand to greatest extent again to tap water pipe network all the time, reduce water supply consumption, realize water system optimized operation.
As optimization, described is skewed for weed buffer 6 tank body bottom surface, and the lower end of described skewed bottom surface is provided with blow-off pipe 13, and the upper end of described skewed bottom surface is provided with outlet pipe.
In the present embodiment, described air pressure tank 7 is capsule type air-pressure tank, and the inside of described capsule type air-pressure tank is provided with an overall air bag, and during work, water enters described air bag, and not with the body contact of capsule type air-pressure tank.General, described air pressure tank 7 has multiple, and described multiple air pressure tank 7 is connected in the mode being connected in parallel water supply, and the parallel connected end water inlet of described air pressure tank 7 is provided with and prevents refluence device.
In the present embodiment, also comprise control panel, described control panel, programmable logic controller (PLC) 8 and frequency converter and be arranged on a small controller cabinet 2, described small controller cabinet 2 is arranged on described falsework 9, described small controller cabinet 2 is also equiped with junction block and touch-screen, described junction block is for connecting power supply, and described touch-screen is used for peripheral operation and display.
This external water supply end is provided with water supply end pressure sensor 14, and at air pressure tank 7, place is provided with remote transmission sensor.
The beneficial effects of the utility model:
1, automaticity is high, reliable, convenient operating maintenance, does not need special messenger to nurse.
2, energy-efficient, make full use of the pressure of well pump, effective, play the energy-saving effect of frequency control to greatest extent.
3, the clean health of supply equipment, adopts way of supplying water airtight continuously and filter, decreases pollution of waterhead problem.
4, domestic intelligent constant pressure water supply system operation noise is low, and most of the time, particularly night are in low noise running status.
5, this water system has buffering and dynamic compensation effect concurrently, and floor space is little, and structure is simple, has more market value.
