Description
Technical field
The utility model relates to flow automatic control technology field, is particularly a kind ofly suitable for the living pump energy-saving control device that highrise building is used.
Background technology
At present generally adopt variable frequency pump constant pressure water supply mode for the living pump on highrise building, this way of supplying water is compared with traditional main frequency water pump way of supplying water, because having environmental protection, the advantage that energy-conservation and quality of water supply is high is generally admitted.
Constant pressure water supply system adopts potentiometer setting pressure, with the pressure in a pressure sensor detection water supply network, and pass the signal to frequency convertor PID loop, after pid loop is processed, frequency converter is automatically adjusted output frequency, is sent the signal that the water yield should increase or reduce according to condition, and control the rotating speed of pump motor, actual ductwork pressure and setting pressure are reached unanimity.In addition, in the time that water supply volume reduces, frequency converter reduces output frequency automatically, reduces pump motor rotating speed, realizes energy-saving effect.
But in concrete enforcement, because the core control part of existing living pump is PID controller, when the work of PID controller, exist hyperharmonic to have the defect of residual error, in the time that pressure sensor is sent signal into frequency convertor PID control loop, the situation that it overshoot likely occurs or adjust time delay the speed governing of pump motor, and because the working curve of pid loop control pump rotary speed is non-linear, cause water pump that violent shake easily occurs in running, even produce the situation of stall, thereby job stability and reliability all poor, though there is energy-saving effect, but effect is not remarkable, therefore consider from economy and point of view of practicability, still owe desirable.
Summary of the invention
The purpose of this utility model is existing overshoot will overcome existing living pump control device taking PID controller as core work time, has residual error, the non-linear and inapparent defect of energy-saving effect, provide a kind of be convenient to living pump carry out in real time, accurately, the energy-saving control device of level and smooth control.
Living pump energy-saving control device of the present utility model, include switch board, electrical communications wire and water pump component, be characterised in that: in described switch board, be provided with by PLC programmable controller and fill the post of core control part, described electrical communications wire includes working power line and data information transfer wire, described water pump component includes water inlet manifold, outfall sewer, intake pressure sensor, discharge pressure sensor, water flow sensor and on electrical ball valve with go out the water pump of water regulating valve, wherein: described water inlet manifold with described on the water inlet end water route of water pump with electrical ball valve be connected, be provided with described intake pressure sensor above, described outfall sewer with described on take the water pump of water regulating valve out of water route, water side be connected, be provided with described discharge pressure sensor and water flow sensor above, described electrical communications wire is arranged between described switch board and water pump component.
When work, living pump energy-saving control device of the present utility model gathers the pressure of water supply network and water outlet pipe network by pressure sensor and flow transmitter, the operational factors such as flow, and these non-electrical parameters are converted to the electrical parameter of standard, then be sent to PLC programmable controller, PLC programmable controller is analyzed judgement by the historical data that is stored in internal memory to it according to above-mentioned parameter, and prediction and infer the water system load in following moment, and the required output of this load, again according to the real-time lag time of system, water system is controlled in advance, regulate the output frequency of living pump frequency converter, control the rotating speed of water pump, change its flow, the water supply flow that system is provided, pressure and workload demand match.
The utility model living pump energy-saving control device based on above-mentioned design, owing to having adopted the core component of PLC programmable logic controller as control device, and on water inlet manifold, be provided with to have and gather the in real time intake pressure sensor of water inlet data function, on outfall sewer, be provided with discharge pressure sensor and the water flow sensor with Real-time Collection water outlet data function, the water supply of real-time tracking monitoring living pump, the pressure of water outlet and flow, and regulate and control in time the rotating speed of pump motor according to operating mode, make living pump work in all the time with workload demand match for water state, have and control in real time, accurate and level and smooth, water saving outstanding feature, existing overregulation or not enough overshoot while effectively having overcome traditional control device work that to adopt PID controller be core component, there is the nonlinear defect of residual sum, reliable operation, stable and energy-conservation, there is very strong practicality and valuable market application foreground.
