Detailed description of the invention
Fig. 1,2,3 and 4 show full automatic control unit able to programme, and it is arranged on base 1, including first-level pipeline network blood circulation, secondary network blood circulation, water charging system and switch board 9.First-level pipeline network blood circulation uses first-level pipeline network feed water inlet H1 through the first y-type filter 4, electric control valve 3, first-level pipeline network water supply arm 11 is connected to the first heat-exchangers of the plate type 2 by the first first-level pipeline network water supply water inlet pipe 11a the most respectively, second first-level pipeline network water supply water inlet pipe 11b is connected to the second heat-exchangers of the plate type 2a, it is communicated to be arranged on the first-level pipeline network water return outlet HR1 of first-level pipeline network return branch 12 end again by the first first-level pipeline network backwater exit branch 12a being arranged on the first heat-exchangers of the plate type 2 and the second first-level pipeline network backwater exit branch 12b being arranged on the second heat-exchangers of the plate type 2a；Secondary network blood circulation uses secondary network water return outlet HR2 through circulating pump arm 6a, circulating pump 6, secondary network return branch 13, it is connected to the first heat-exchangers of the plate type 2 the most respectively by the first secondary network backwater water inlet pipe 13a, second secondary network backwater water inlet pipe 13b is connected to the second heat-exchangers of the plate type 2a, it is connected to be arranged on the secondary network feed water inlet H2 of secondary network water supply arm 14 end again by the first secondary network water supply exit branch 14a being arranged on the first heat-exchangers of the plate type 2 and the second secondary network water supply exit branch 14b being arranged on the second heat-exchangers of the plate type 2a；Water charging system uses water tank 10 to be connected to circulating pump arm 6a through water supplement port 5a, small pump 5；The relief valve 8 of relief valve port 8a it is provided with on circulating pump arm 6a；Switch board 9 is electrically connected with circulating pump 6 through converter, and switch board 9 is electrically connected with small pump 5 through converter.
When using technique scheme work, water is entered by first-level pipeline network feed water inlet H1, through the first y-type filter 4, electric control valve 3, first-level pipeline network water supply arm 11 enters the first heat-exchangers of the plate type 2 by the first first-level pipeline network water supply water inlet pipe 11a the most respectively, second first-level pipeline network water supply water inlet pipe 11b enters the second heat-exchangers of the plate type 2a, the first first-level pipeline network backwater exit branch 12a and the second first-level pipeline network backwater exit branch 12b being arranged on the second heat-exchangers of the plate type 2a by being arranged on the first heat-exchangers of the plate type 2 are pooled to be arranged in first-level pipeline network return branch 12 again, discharged by first-level pipeline network water return outlet HR1 again；Water is entered by secondary network water return outlet HR2, through circulating pump arm 6a, circulating pump 6, secondary network return branch 13, enter first heat-exchangers of the plate type the 2, second secondary network backwater water inlet pipe 13b by the first secondary network backwater water inlet pipe 13a the most respectively and enter the second heat-exchangers of the plate type 2a, it is pooled to secondary network water supply arm 14 by the first secondary network water supply exit branch 14a being arranged on the first heat-exchangers of the plate type 2 and the second secondary network water supply exit branch 14b being arranged on the second heat-exchangers of the plate type 2a again, then is discharged by secondary network feed water inlet H2.Water in water tank 10 entered water supplement port 5a and is pumped in circulating pump arm 6a by small pump 5 and carries out moisturizing.The switch board 9 flow by Frequency Converter Control small pump 5, the switch board 9 flow by Frequency Converter Control circulating pump 6.
According to outdoor temperature and secondary water-supply temperature relation setting curve, it is automatically adjusted primary side flow, it is ensured that the temperature required for user.One-level water supply network arranges electric hydaulic regulation valve, change according to secondary water-supply temperature, outdoor temperature makes comparisons (temperature curve can require to arrange according to user) with being set in advance in director demon local heating demand curve, then make PID arithmetic output 0-10V signal and regulate valve actuator to electric hydaulic, executor drives the aperture of valve core regulation electric control valve, change once pipe net flow, secondary side supply water temperature changes the most therewith, it is achieved once the amount regulation of pipe net flow and the matter of secondary side supply water temperature regulate.
Frequency conversion automatic constant-pressure moisturizing, supplementing water pressure can set, and can report to the police when breaking down；Unit, according to setting pressure reduction, is supplied water by converter and circulating pump automatic constant pressure reduction.In secondary pipe network, circulating pump 6, small pump 5 all use VFC.Unit is after putting into operation, and because many reasons not necessarily can run under rated load, after particularly realizing household-based heat metering, load variations fluctuation is very big, and the resistance of secondary pipe webmaster also changes, and heat exchanger supply head changes the most therewith.Control circulating pump converting operation by the backwater pressure reduction that supplies of secondary network, reach to save electric energy, the purpose of heat energy.Secondary records pressure signal for the pressure transducer on water return pipeline, via controller calculates actual pressure differential value and contrasts with controller pressure differential resetting value, after PID arithmetic, regulate cycloconvertor frequency, change circulating pump 6 rotating speed, thus realize secondary circulation system constant-pressure drop and run.When a frequency variable circulating pump full-speed operation does not still reach setting pressure reduction, controller starts power frequency circulating pump, the simultaneously regulation of variable frequency pump reduction of speed automatically, prevents the unexpected supercharging of system pipe network, the safety of protection pipe network.Secondary heat supply network moisturizing is frequency-changing pressure stabilizing moisturizing, records signal according to the pressure transducer being contained in secondary returning water lines and compares with setting value in controller, then exports to converter through PID arithmetic, reaches the purpose of stabilisation systems pressure regulating small pump motor speed.
Manually operated step computer is carried out working out control program, makes plant equipment be controlled step by step performing according to the program that computer controls, produce corresponding action.Converter is used to combine with programmable controller, utilize PID proportional integral link that the digital signals such as an on-the-spot secondary network supply and return water temperature, pressure are converted into analogue signal and carry out proportional integral calculating, give PC process afterwards, result after process is converted into switching value and gives converter and catalyst realization output control, again output is sent into input and input signal compares superposition, it is re-fed into input, forms closed loop control.
