Abstract
The invention relates to a calibration method for a pump valve specialist performance curve. Based on a chip, the determination work whether the operating point of a pump at work is in an efficient region is realized through a built-in pump valve mathematical model; and the operating point of the pump can be raised to the efficient region to operate through a built-in curve calibration function. The chip tracks the performance curve of the actual operating point of the operating pump in real time and monitors whether the operating point is in the preset efficient region; once the operating point of a water pump deviating from the efficient region is monitored, the chip adopts a calibration function and improves the efficiency of the operating point of the pump through changing the frequency of the water pump; if the curve calibration occurs three times (default value) for regulating, the chip performs monitoring and comparion of energy consumption; and when the chip finds that the pump does not save energy obviously after being regulated and operating for 1h, the chip stops the curve calibration function and gives an alarm to remind related workers of maintaining.
Description
Technical field
Application of the present invention be a kind of pump valve expert performance curve calibration steps; 10 data points that this method can be dispatched from the factory and detect according to water pump; It simulates the performance curve of water pump through the Lagrange's interpolation theorem; Thereby can detect the operating point of water pump in real time; And judge through Sigma's standard whether this pump is operated in efficient region, and work that can be through adjusting this pump frequently the operating point of this pump move efficient region work to, thereby for solving the very big energy waste problem that water pump causes in non-efficient region work.
Background technique
At present, the pump series products has consumed 20% electric energy in the world, and this wherein about 50% is wasted, and usually works long hours at non-efficient region for some reason and wasting main cause is a pump.If utilize advanced mathematical model, in conjunction with the technological speciality of industry specialists, the energy of these wastes just can be saved easily; These energy that are wasted have produced serious consequence to pump and pump group system, and pump has to consume these energy through the mode of heating, noise, vibration.
Summary of the invention
The technological method of a kind of special use of main invention, this method is support with the chip, merges three big power function storehouses such as pump valve mathematical model, pump performance curve fitting, calibration curve; As long as the configuring chip parameter can guarantee that pump rationally moves at efficient region simply; Except whether monitoring pump operating point meets the efficient region of performance curve, also be furnished with Sigma's examination criteria, when pump during, start the calibration curve function in non-efficient region operation, the operating point of pump is promoted to efficient region work.
Description of drawings
Below in conjunction with accompanying drawing and implementation methods the present invention is further specified.
Fig. 1 is made up of the chip of (1) variable frequency drives, (2) built-in pump valve expert performance curve calibration steps.Embodiment: in Fig. 1, variable frequency drives (1) is mainly used in the frequency of okperation that changes water pump; The chip (2) of built-in pump valve expert performance curve calibration steps is then mainly accomplished pump valve expert performance curve correction function.
Embodiment
The technical solution adopted for the present invention to solve the technical problems is: propose a kind of pump valve expert performance curve collimation technique method; It is support with the chip; When accomplishing pump work through built-in pump valve mathematical model to its operating point whether in the affirmation work of efficient region; And, can the operating point of pump be risen to the efficient region operation through built-in calibration curve function.The concrete configuration process is following:
1, before pumping factory, the operating point of pump is sampled, generally take 10 points; And with these data points through the configuration tool burning in pump valve expert performance curve collimation technique chip.
2, the monitoring range of performance curve efficient region is given definition, be defaulted as between-5%～+ 5%, can revise.
3, the calibration curve number of attempt is provided with, and is defaulted as 3 times; Can revise.
4, launch pump valve mathematical model, pump performance curve fitting, the calibration curve function of this chip internal.
Through above configuration, chip moves real-time tracking the performance curve of water pump actual conditions point; And whether monitor this operating point in preset efficient region scope; Departed from efficient region in case monitor the operating point of water pump, chip will be taked correction function, improve the operating point efficient of pump through the frequency that changes water pump; In when adjustment, if behind the calibration curve 3 times (default value), chip is found adjustment back operation 1 hour through the energy consumption monitoring contrast, pump does not have obvious when energy-conservation yet, will stop the calibration curve function, and give to report to the police, and reminds the related personnel to safeguard.
The function of this chip mainly comprises: several parts such as CPU element, data storage area, pump valve mathematical model storehouse, pump performance curve fitting storehouse, calibration curve storehouse.CPU element is mainly coordinated the overall work of each functional zone; The data storage area is used for the long-term or ephemeral data of storage; Pump valve mathematical model storehouse mainly realize with advanced person's mathematical algorithm with the form access of function library in model base, can conveniently call at any time so first, moreover can further expand additional novel algorithm; Pump performance curve fitting storehouse mainly is that the detection data fitting with pump is the curvilinear equation that meets pump characteristics, informs CPU in real time, and whether current pump operating point meets the efficient curve of pump; The function of efficient point mainly is responsible for through the operation frequency that changes pump the operating point of pump being drawn in the calibration curve storehouse.
The invention has the beneficial effects as follows, utilize pump valve expert performance curve collimation technique chip, can simulate the performance curve that meets water pump apace automatically, and whether the operating point that can monitor water pump is in the efficient scope of its performance curve; Especially estimable is, it can be through the frequency of okperation of adjustment pump, the working efficiency of elevator pump moderately, thus guarantee that the water pump real-time working is at high efficiency range.For the water pump that is provided with the calibration curve number of attempt; This function will be monitored operation energy consumption; Hour situation of change of energy consumption before and after the contrast adjustment; Variation is not obvious promptly not to be had under predetermined ratio in the front and back energy consumption through the adjustment operating point when monitoring, and it will be safeguarded through the related personnel with the form of warning message; And meet the requirements through energy-conservation ratio, then can in the data area, store information such as the time of adjustment, adjusted amount of energy saving synchronously, so that the technician checks analysis.Its bright spot is through meeting actual mathematical model, be equipped with physical principle, farthest practicing thrift the energy waste of water pump when transformation of energy, in the hope of reaching the purpose of utilizing water pump more efficiently.
