Description
Technical field
The utility model relates to the level gauge device in a kind of dynamo-electric field, especially a kind of multi-level accurate measuring device.
Background technology
Liquid meter mode commonly used at present has two kinds, and a kind of is that peristaltic pump measures, and the method is simple and convenient, and cost is moderate, and failure rate is low; But owing to the limitation of itself structure causes that metering is inaccurate; Like gapped meeting between the peristaltic pump roller fluid produce to be paused, in addition peristaltic pump tube used of a specified duration can distortion, and receive Changes in weather and expand with heat and contract with cold; The long-time use, peristaltic pump tube abrasion deformation can cause that metering is inaccurate.Another kind of be the syringe pump metering, the method accuracy of measuring height uses also more conveniently, but cost an arm and a leg, and syringe pump directly contacts with liquid, influences device serviceable life.
The utility model content
The fundamental purpose of the utility model is, overcomes the defective that existing peristaltic pump pump line exists, and a kind of multi-level accurate measuring device of new structure is provided; Technical matters to be solved provides a kind of accurate measurement; Simple in structure, with low cost, failure rate is low; Thereby be more conducive to practicality, and have the value on the industry.
The purpose of the utility model and solve its technical matters and adopt following technical scheme to realize.A kind of multi-level accurate measuring device according to the utility model proposition; Comprise metering pedestal, gauge line and peristaltic pump; Said metering pedestal internal fixation is provided with gauge line, and an end of the top of said gauge line and top connection is connected, and an end of the other end of said top connection and pump line is connected; One end of the bottom of said gauge line and lower sub is connected; The other end of said lower sub links to each other with inlet, it is characterized in that, on said metering pedestal, is fixed with the induction installation that communicates connection with gauge line.
Aforesaid multi-level accurate measuring device; Wherein, Said induction installation comprises high-order photoelectric sensor and low level photoelectric sensor, on said metering pedestal, is respectively arranged with the high-order photoelectric sensor and the low level photoelectric sensor that communicate connection with gauge line from top to bottom.
By technique scheme, the utility model multi-level accurate measuring device has advantage at least:
The multi-level accurate measuring device of the utility model uses the peristaltic pump negative pressure to suck, and between liquid and pump line, always has an air cushioning district, has avoided the corrosion of pump line; Measure through high-order, low level photoelectric sensor, accurate measurement, simple in structure, with low cost, failure rate is low.
In sum, the multi-level accurate measuring device of the utility model special construction, it has above-mentioned many advantages and practical value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of instructions, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
Description of drawings
Fig. 1 is the structural representation of the described multi-level accurate measuring device of the utility model.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to the embodiment of the utility model specify as after.
As shown in Figure 1; A kind of multi-level accurate measuring device; Comprise metering pedestal 3, gauge line 4 and peristaltic pump 1, metering pedestal 3 internal fixation are provided with gauge line 4, and the top of gauge line 4 is connected with the end of top connection 9; One end of the top of top connection 9 and pump line 2 is connected; The bottom of gauge line 4 is connected with the top of lower sub 7, and the end of lower sub 7 links to each other with inlet 6, on metering pedestal 3, is fixed with the induction installation that communicates connection with gauge line 4; Induction installation comprises high-order photoelectric sensor 8 and low level photoelectric sensor 5, on the both sides of metering pedestal 3, is respectively arranged with the high-order photoelectric sensor 8 and low level photoelectric sensor 5 that communicate connection with gauge line 4 from top to bottom.
When the needs low level measured, control peristaltic pump motor made peristaltic pump 1 running, produces negative pressure, and liquid enters into gauge line 4 through inlet 6; When liquid height rises to low level photoelectric sensor 5 present positions, low level photoelectric sensor 5 output high level, peristaltic pump 1 shuts down, thus realize liquid the low level metering; High-order metering in like manner.
When the high-order metering of needs, control peristaltic pump motor makes peristaltic pump 1 running, produces negative pressure, and liquid enters into gauge line 4 through inlet 6; When liquid height rises to high-order photoelectric sensor 8 present positions, low level photoelectric sensor 5 output high level, peristaltic pump 1 shuts down, thus realize liquid high position metering.
The multi-level accurate measuring device of the utility model uses peristaltic pump 1 negative pressure to suck, and between liquid and pump line 2, always has an air cushioning district, has avoided the corrosion of pump line 2; Measure through high-order photoelectric sensor 8, low level photoelectric sensor 5, accurate measurement, simple in structure, with low cost, failure rate is low.
The above; It only is the preferred embodiment of the utility model; Not being that the utility model is done any pro forma restriction, though the utility model with the preferred embodiment exposure as above, yet is not in order to limit the utility model; Anyly be familiar with the professional and technical personnel; In not breaking away from the utility model technical scheme scope, make a little change or be modified to the equivalent embodiment of equivalent variations when the technology contents of above-mentioned announcement capable of using, be the content that does not break away from the utility model technical scheme in every case;, all still belong in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
