Description
Technical field
The utility model belongs to the measurement calculation element, especially relates to a kind of integrated control unit of directly calculating the water pump real-time traffic with water pump.
Background technology
At present, water pump is exactly the equipment that is used to provide liquid flow required drive in the pipeline, the flow measurement of liquid need be finished with the flow rate test equipment of special use in the pipeline, traditional flow measurement has ultrasonic flow meter, electromagnetic flowmeter, orifice flowmeter etc., these testing apparatus expense height, on-the-spot mounting condition requires than higher (requiring certain straight length etc.), and under the different situation in the position of measuring, measured value and the certain deviation of actual value ubiquity.Under the situation of a plurality of parallel connection of pumps operations, the actual situation of exerting oneself that can't the independent analysis single pump, (for example: parameters such as pump shaft power, pump efficiency) read more water pump operation parameter as needs, also need to increase testing apparatus, and can not in time accomplish to read in real time parameter, instruct production safety, energy-saving run difficult.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, and can direct modeling goes out the parameter such as real-time traffic, lift, effect of water pump, makes pumping plant device overall operation efficiency higher.
In order to achieve the above object, the technical solution adopted in the utility model is: have on the import and export flange of water pump in threaded hole and the water pump and communicate, at threaded hole place setting pressure sensor, the pumping hole that corresponding caliber is installed on the import and export flange of water pump prolongs straight tube, setting pressure sensor on it, motor links to each other with water pump by screw, and transmission gear for electric motor links to each other by cable with motor, and pressure transducer, transmission gear for electric motor, operation display interface link to each other with controller by signal wire.
The utility model has the advantages that:
Compact conformation, reasonable in design, use this control device, the parameter such as real-time traffic, lift, efficient that can direct modeling goes out water pump instructs production run, reduced the unnecessary power consumption that rich flow of water pump and margin head cause, adopt the method for software and hardware combining, make pumping plant device overall operation efficiency higher, thereby keep the pumping plant device not only satisfying operating condition simultaneously but also carry economical operation under the state of water power unit consumption minimum, therefore, this measurement mechanism has efficient energy-saving, make the flow measurement of water pump simple more, practical, convenient, integrated cost is low.

Fig. 2 is the utility model block diagram;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model has on the import and export flange of water pump 1 in threaded hole and the water pump 1 and communicates, at threaded hole place setting pressure sensor 2, the pumping hole that corresponding caliber is installed on the import and export flange of water pump 1 prolongs straight tube 7, setting pressure sensor 2 on it, motor 3 links to each other with water pump 1 by screw, and transmission gear for electric motor 4 and motor 3 link to each other by cable, and pressure transducer 2, transmission gear for electric motor 4, operation display interface 6 link to each other with controller 5 by signal wire.
The utility model water pump integrated control unit is by gathering the pressure signal of water pump suction inlet, discharge opening in real time, and the correction factor that adds when adding field adjustable, calculate the actual lift of pump operation, simultaneously in controller, go out the power frequency family curve of pump, real time execution curve, dynamic characteristic, the water pump operation working point under the frequency conversion, the efficient of water pump operation working point by senior algorithm simulations such as PLC programming languages; Simultaneously also can the function that realtime power the shows teletransmission function of watt-hour meter (or with) be arranged by frequency converter, with the realtime power of pump operation, day parameter such as power consumption show.Just finished the Presentation Function of water pump operation parameters like this by simple mode.According to the energy-saving potential of the pumping station system of calculating, remove to control the original equipment of operation pumping station system and the equipment of design by satisfying the low again mode of technological requirement specific yield power consumption simultaneously.Use this integrated control unit, the parameter such as real-time traffic, lift, efficient that can direct modeling goes out water pump instructs production run, therefore not only reduced the unnecessary power consumption that rich flow of water pump and margin head cause, adopt the method for software and hardware combining, make the pumping station system overall operation efficiency the highest, thereby keep pumping station system not only satisfying operating condition simultaneously but also carry economical operation under the state of water power unit consumption minimum.So, the energy-saving effect that uses it to obtain is bigger than the energy-saving effect that uses variable-frequence governor to obtain separately, realizing again on the existing speed regulator basis that energy-saving effect is different and different with running status because of the characterisitic parameter of each transporting water system about economize on electricity 7%-33%.
Have on the import and export flange of water pump described in the utility model in threaded hole and the water pump and communicate, be used for measuring the pressure in pump entrance and exit at threaded hole place setting pressure sensor, motor links to each other with water pump body by screw, the pumping hole that corresponding caliber is installed on the import and export flange of water pump prolongs straight tube, the setting pressure sensor is used for measuring the pressure in pump entrance and exit on pumping hole prolongation straight tube, and motor links to each other with water pump by screw.Transmission gear for electric motor links to each other by cable with motor, pressure transducer, transmission gear for electric motor, operation display interface link to each other with controller by signal wire, can see every operational factor (comprising parameters such as pump capacity, efficient) of water pump by operation display interface, and, make water pump operation near energy-efficient point by controller control transmission gear for electric motor control water pump operation.
