Description
Technical field
The utility model belongs to the fields of measurement of metering pump, particularly relates to a kind of flow measuring device of accurate measuring pump.
Background technique
Along with the development of instrument and meter industry, current flow measuring device is of a great variety, but the fluid flow that the equipment such as Electromagnetic diaphragm metering pump, mechanically actuated diaphragm metering pump exports is little, and liquid exports with pulsed.Now the most frequently used at present flow measuring device is electromagnetic flowmeter and ultrasonic flowmeter, the fluid requirements that they all exist measuring is high, error can not carry out the problem such as measuring more greatly accurately, so for the flow measurement of metering pump and flow check and correction, then can only the pipe of metering pump liquid outlet be placed in graduated cylinder, throughput socket joint liquid, then according to the volume of measurement and the time of record, flow can be measured and draw the average external volume of liquid within the unit time, described method carries out the measurement of flow and check and correction is wasted time and energy, and unsafe factor is existed for the measurement of etchant solution.
Model utility content
The purpose of this utility model is: be solve the deficiencies in the prior art, provides a kind of flow measuring device of safe and reliable, measuring accuracy is high, structure is simple, easy to operate, time saving and energy saving metering pump.
For achieving the above object, the technical solution of the utility model is:
A kind of flow measuring device of metering pump, one end of first pipeline is connected with the liquid outlet of metering pump, the other end of the first pipeline is connected with container and the 3rd pipeline respectively, container is connected with second pipe, second pipe is connected with drain pipe with after the 3rd ducts converge, and described container upper end is provided with liquid level detection device two, and timer is connected with liquid level detection device two, timer is connected with metering pump, and the 3rd pipeline is provided with corrosion resistant valve.
Further, the lower end of described container is provided with liquid level detection device one.
Further, described liquid level detection device two is photoelectric liquid-levle detection device or float-type liquid level tester.
Further, described liquid level detection device one photoelectric liquid-levle detection device or float-type liquid level tester.
Further, described corrosion resistant valve is stainless valve or Plastic valve.
Further, described container is glass material or plastic material.
Owing to have employed such scheme, the beneficial effects of the utility model are: overcome the deficiencies in the prior art, and the utility model structure is simple, easy to operate, can the flow of Measurement accuracy metering, and can also ranging pulse flow; Adopt positive displacement measuring flow, measuring accuracy is high; This structure is time saving and energy saving simultaneously, safe and reliable, and range of applicability is wide, can be used for the measurement of etchant solution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the fundamental diagram of timer.
Reference character: 1-metering pump, 2-first pipeline, 3-liquid level detection device one, 4-container, 5-liquid level detection device two, 6-second pipe, 7-corrosion resistant valve, 8-the 3rd pipeline, 9-drain pipe, 10-timer.
Embodiment
Embodiment 1: composition graphs 1, Fig. 2, the flow measuring device of described a kind of metering pump, one end of first pipeline 2 is connected with the liquid outlet of metering pump 1, the other end of the first pipeline 2 is connected with container 4 and the 3rd pipeline 8 respectively, container 4 is connected with second pipe 6, be connected with drain pipe 9 after second pipe 6 and the 3rd pipeline 8 converge, the volume of described container 4 is quantitatively known, the lower end of container 4 is provided with photoelectric liquid-levle detection device, the upper end of container 4 is provided with photoelectric liquid-levle detection device, timer 10 is connected with the photoelectric liquid-levle detection device of container 4 upper end, timer 10 is connected with metering pump 1, 3rd pipeline 8 is provided with stainless valve.
Because the capacity of container 4 is known before measuring, but it is unknown from the fluid to be measured volume in metering pump output pipeline, so the total volume of fluid to be measured first need be measured, fluid to be measured is full of container 4 by metering pump 1 with pulsed output, then graduated cylinder is placed on liquid outlet 9 and connects liquid, open electric control valve 7, fluid to be measured flows into graduated cylinder by self gravitation by the 3rd pipeline 8 and drain pipe 9, and can record total volume according to graduated cylinder is V;
After liquid during measurement in confirmation container 4 all flows out, then fluid to be measured is exported with pulsed by metering pump 1, after sending pulse signal, timer 10 starts timing, when the photoelectric liquid-levle detection device that fluid to be measured is made up of light emitting diode and reception diode through container 4 upper end, fluid to be measured blocks light path, reception diode sends pulse signal after experiencing the change of light intensity, by timer 10 T writing time;
Can draw the flow of metering pump according to V/T, the umber of pulse according to metering pump in T time can obtain pulse flow, is more than measured as one-period and measures, first time measure before to measure after definite value volume V then next cycle without the need to again measuring.After metering pump work a period of time, repeat the check and correction that aforesaid operations carries out metering pump.The measuring accuracy of described flow measuring device is high, convenient and simple for operation, time saving and energy saving, safe and reliable.
