Embodiment
Embodiment mono-,
The present embodiment proposes a kind of washing facility, by electric quantity acquisition module and water yield acquisition module being installed at washing facility, Real-time Collection is also added up power consumption and water yield loss, embodies at any time power consumption situation on each equipment, and side easy to use grasps the cost power consumption accurately of different washing articles.
Particularly, the present embodiment is with the washing facility of energy consumption writing function, comprises primary processor, enters goddess of lightning's line, the female pipe of water inlet, also comprises electric quantity acquisition module and water yield acquisition module;
Electric quantity acquisition module comprises the current sampling circuit and the voltage sampling circuit that are connected on goddess of lightning's line, the output terminal of current sampling circuit and voltage sampling circuit connects respectively two input ends of primary processor, processor calculates power consumption output according to the sample rate current of input and sample voltage value, the present embodiment current sampling circuit is a current transformer, and voltage sampling circuit is a potential-divider network.Certainly, electric quantity acquisition module also can be selected existing DAM-3503/T electric quantity acquisition module, it comprises that external current transformer, built-in house dog and plate carry Temperature Humidity Sensor, voltage range is that 400V, current range are 5A, precision for ± 0.2%, isolation voltage is 3000 V, and the terminal of DAM-3503/T electric quantity acquisition module is socketed on goddess of lightning's line.
Water yield acquisition module is vortex shedding flow meter, this vortex shedding flow meter is arranged on the female pipe of water by a straight length, the output terminal of vortex shedding flow meter connects the 3rd input end of described primary processor, and primary processor calculates flow loss output according to the umber of pulse of vortex shedding flow meter input.The present embodiment straight length 1 inwall is clean, smooth, obviously convex-concave of nothing.In order to ensure to measure accurately, the internal diameter of vortex shedding flow meter 2 is identical with the internal diameter of straight length 1.The opening part of vortex shedding flow meter upstream and downstream straight length 1 is welded with respectively flange 3, and the sensor 2 of vortex shedding flow meter is clipped between two flanges 3 also fastening by bolt 4, and 1 three is coaxial for flange 3, sensor 2, straight length.The length of vortex shedding flow meter upstream and downstream straight length 1 is respectively 17 times and 7 times of straight length 1 internal diameter.
Vortex shedding flow meter is for measuring the current real-time flow rate of water inlet bus and being uploaded to primary processor, and the present embodiment primary processor adopts Programmable Logic Controller.The Karman vortex street principle of the measuring method of vortex shedding flow meter based in fluid mechanics.A swirl generating body (as the blunt form such as right cylinder, triangulo column symmetric objects) is vertically inserted in pipeline, in the time that walking around swirl generating body, fluid can alternately produce vortex at its rear, left and right sides, form vortex row, and the sense of rotation of left and right sides vortex is contrary.This vortex row are just called Karman vortex street.Owing to influencing each other between vortex, vortex row are generally unsettled, and in the time that the distance h between two vortexs row and the distance L between two vortexs of same column meet formula h/L=0.281, asymmetrical vortex row just can keep stablizing.Now the mean flow rate υ of the frequency f of vortex and fluid and the width d of swirl generating body have following relation: f=St υ/d.In formula, St is Si Telaohaer coefficient, relevant with fluid reynolds number Re with swirl generating body width d.In the scope that is 2*104 ~ 7*106 at reynolds number Re, St is a constant, and swirl generating body width d is also definite value, and the frequency f that therefore vortex produces is directly proportional to the mean flow rate υ of fluid.According to the relation of volumetric flow rate and flow velocity, can derive the relational expression of volumetric flow rate qv and vortex frequency f: qv=f/K again.In formula, K is flowmeter coefficient of flow, and its physical significance is the umber of pulse of every up-flow body.In the time that flowmeter pipeline inner diameter D and swirl generating body width d are determined value, K value is also determined thereupon.Programmable Logic Controller is by its specialized high-speed counter passage, gather the K value of flowmeter---be umber of pulse, in Programmable Logic Controller inside by calculating the pulse accumulative total in the unit interval, can converse flow, and transferring to intelligent flow-integrating instrument, intelligent flow-integrating instrument shows flow with the form of pulse digital signal.
