Description
Technical field
The present invention relates to water pump control technique, particularly a kind of for distributing system improve transmission & distribution efficiency without sensing constant current pump valve integrate device.
Background technique
Water pump and valve are widely used in the device of the distributing systems such as air-conditioner water system, district heating water system, industrial circulating water system, but the operation energy consumption of traditional distributing system is very large, and water pump operation continuously at full capacity often, and automaticity is low.For the obtain manner of flux signal, traditional method is to obtain by flowmeter, and in this process, also wants the participation of pressure transducer, and this process of obtaining signal exists the regular hour to postpone.After obtaining flux signal, then by regulating the valve in water pump or the frequency of blower fan and pipe network, make adjustment process veryer long, accuracy is not good enough.
Also there is no at present water pump and valve integrated device, and in the process of obtaining at flux signal, there is no again the participation of pressure transducer.Integrated and the technological means of saving pressure transducer of pump valve is problem to be solved by this invention just.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the deficiency in present technology, provide a kind of pump valve integrated and without pressure transducer just can obtain flux signal without sensing constant current pump valve integrate device.
For solving the problems of the technologies described above, the present invention is implemented by the following technical programs:
Provide a kind of without sensing constant current pump valve integrate device, comprise water pump; The motor of water pump is connected with information monitoring and analytical equipment, on the suction line of water pump and outlet line, valve body adjusting part is set respectively; Information monitoring and analytical equipment, two valve body adjusting parts are connected to tenminal block by cable respectively, and tenminal block connects programmable controller, process control machine successively through cable; Built-in flow computing module in described information monitoring and analytical equipment, wherein stores water pump characteristics operation curve, and this in when operation device current and voltage signals and the corresponding relation data of flow.
In the present invention, described valve body adjusting part is manual modulation valve or electric control valve.
In the present invention, described tenminal block connects the input end of programmable controller through cable, and the digital quantity of programmable controller is directly connected with information monitoring and analytical equipment with analog output end.
Beneficial effect of the present invention is:
The present invention and traditional flux signal obtain manner are different, without sensor, obtain flux signal, in this device, be built-in with flow computing module, wherein store water pump characteristics operation curve, and have accordingly the flow of enough data volumes and the corresponding relation of current/voltage with this characteristic operation curve.According to current and voltage signals in this device running, this device just can find now corresponding flow parameter by flow computing module.Process control machine is using the aperture of this device as optimization target values, its result is directly transferred to programmable logic controller (PLC), by control valve aperture, guarantee the constant flow of whole transmission and distribution network, this is for the distributing system of a lot of water systems, there is very large benefit, because it has guaranteed user's demand, there will not be undercurrent or over-current phenomenon avoidance.This device can just can obtain flux signal by obstructed excess pressure sensor, makes to be input to last control output time from signal short, and reaction is fast, more accurate.

Fig. 2 water pump operation curve.
In figure: 1 water pump, 2 information monitorings and analytical equipment, 3 valve body adjusting parts, 4 tenminal blocks, 5 programmable controllers, 6 process control machines.
Embodiment
First it should be noted that, the present invention relates to computer technology in a kind of application in control technique field.In implementation procedure of the present invention, can relate to the application of software function module.Claimant thinks, as reading over application documents, accurate understanding is of the present invention realize principle and goal of the invention after, in conjunction with existing known technology in the situation that, those skilled in the art can use the software programming technical ability of its grasp to realize the present invention completely.Aforementioned software function module comprises but is not limited to: flow computing module etc., and this category of all genus that all the present patent application files are mentioned, claimant will not enumerate.
Below by embodiment, by reference to the accompanying drawings, technological scheme of the present invention is described in further detail:
In Fig. 1, provided the schematic flow sheet of this device.
Without sensing constant current pump valve integrate device, comprise water pump 1, the motor of water pump 1 is connected with information monitoring and analytical equipment 2, on the suction line of water pump 1 and outlet line, valve body adjusting part 3 is set respectively, and valve body adjusting part 3 is manual modulation valve or electric control valve.Information monitoring and analytical equipment 2, two valve body adjusting parts 3 are connected to tenminal block 4 by cable respectively, and tenminal block 4 connects programmable controller 5, process control machine 6 successively through cable.
In the present invention, information monitoring and analytical equipment 2 are mature technologies, can select the Smart1000IE6AV66480BE113AXO of SIEMENS, are mainly used in the present invention information monitoring and the analysing and processing of motor operating parameter.At this device run duration, information monitoring and analytical equipment 2 are monitored the voltage and current signal of water pump 1 motor in real time.When load changes, voltage and current signal also changes thereupon, and the power of water pump 1 motor is the product of electric current and voltage and power factor, and power of motor is relevant to the power of water pump, and the power of water pump 1 is again the function of flow and lift,
N=QHρ/102η=9.8QH/η
Flow operation module in information monitoring and analytical equipment 2 stores water pump feature operation curve (as Fig. 2), and this operation curve can be demarcated acquisition when water pump dispatches from the factory; Flow operation module has also stored and this characteristic operation curve corresponding abundant flow and current/voltage corresponding relation data simultaneously, according to the current and voltage signals monitoring, just can obtain corresponding pump capacity parameter.These signals are transferred to process control machine 6, through the analysis of efficiency optimizer, two valve regulated assemblies 3 are controlled, by the aperture of control valve assembly 3, make the flow of system keep constant.In whole process, all there is no the participation of pressure transducer, realized sensorless technology.Therefore, this pump valve integrate device and traditional water pump and valve independently technology are compared, and the air horsepower of motor greatly declines, and the speed that information is transmitted is faster accurately.
