Abstract
The utility model discloses an automatic pressure regulating and controlling device for a secondary water supply system, wherein the controlling device is composed of a controller, an electromagnetic flowmeter, a remote transmission pressure gauge and a frequency converter. The controller is respectively connected with the electromagnetic flowmeter, the remote transmission pressure gauge and the frequency converter. The controller consists of a single-chip microcomputer, a flow detection circuit, a pressure detection circuit, a frequency converter control circuit, a display circuit, a key circuit, a clock circuit and a storage circuit, wherein the single-chip microcomputer is respectively connected with the above circuits. The controlling device is capable of automatically regulating the water supply pressure according to the flow of the water supply system. When the flow of the water supply system is increased, the controlling device automatically increases the water supply pressure. Therefore, the pressure and the flow at the extreme pressure point of the pipeline network of the water supply system can be ensured. When the flow of the water supply system is decreased, the controlling device automatically decreases the water supply pressure. Therefore, both the working capacity of a water pump and the water energy consumption of the pipeline network of the water supply system can be reduced.

Above-mentioned controller also comprises display circuit, key circuit, clock circuit, the memory circuit be connected respectively with single-chip microcomputer.
The beneficial effects of the utility model: (1) can regulate pressure of supply water automatically according to water supply pump house water flow size, can effectively reduce the water pump acting, saves electric energy; (2) automatically regulate pressure of supply water, water supply network is under low pressure of supply water for a long time and works, can reduce the pipe network leak rate.
The accompanying drawing explanation
The connection block diagram that Fig. 1 is water system Automatic Regulation Control device;
The hardware that Fig. 2 is controller connects block diagram;
Fig. 3 is water system Automatic Regulation Control device operational flow diagram.
The specific embodiment
In conjunction with Fig. 1 to Fig. 3, the utility model is explained in further detail: water system Automatic Regulation Control device, comprise controller, electromagnetic flowmeter, distance-transmission pressure gauge and frequency converter, controller is connected with electromagnetic flowmeter, distance-transmission pressure gauge and frequency converter respectively.Controller comprises single-chip microcomputer, flow collection circuit, pressure acquisition circuit, transducer control circuit, and single-chip microcomputer is connected with flow collection circuit, pressure acquisition circuit, transducer control circuit respectively.Described controller also comprises display circuit, key circuit 1, clock circuit, the memory circuit be connected respectively with single-chip microcomputer.
Above-mentioned key circuit is mainly used in arranging " water supply flow---the pressure of supply water table of comparisons ".
Above-mentioned display circuit mainly shows the parameters such as current water supply flow, current pressure of supply water, and coordinates key circuit to complete each setting parameter.
This control device is regulated pressure of supply water according to the size of water supply flow automatically by regulating pump rotary speed, when water supply flow increases, control device improves pressure of supply water automatically, with assure feed water pipe network least favorable point discharge pressure and flow, when water supply flow reduces, control device reduces pressure of supply water automatically, to reduce water pump acting and the leakage of the pipe network water yield.
During use, single-chip microcomputer read flow meter present flow rate value No. one time at interval of 1 minute, and the corresponding pressure of supply water setting value a that tables look-up to obtain reads current pressure of supply water value b simultaneously, calculates a and b difference; When pressure difference value is more than or equal to 0.02MPa, single-chip microcomputer is pressed the IP algorithm according to force value a and is calculated PWM pulsewidth increment and PWM pulsewidth, and is defeated by frequency converter, and frequency converter is regulated pump rotary speed by new input parameter value; When pressure difference value is less than 0.02MPa, just turn back to the upper end flow process and again read the flow meter flow value, corresponding pressure of supply water setting value a tables look-up to obtain, again read current pressure of supply water value b, calculate pressure of supply water setting value a and currency b difference, again carry out difference and relatively wait, through reciprocation cycle, thereby realize the control of variable-flow pressure changeable.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art makes in essential scope of the present utility model, modification, interpolation or replacement, also should belong to protection domain of the present utility model.
