Abstract
The utility model relates to a pipe type oil flow capacity sensor, which is characterized in that the utility model adopts a light emitting diode and a light sensitive transistor which are arranged on a blade support bracket. When the oil in pipelines flows and drives the blades to turn, the light sensitive transistor can convert the rotary speed of the blades into voltage pulse. Owing to adopting the principle that the light emitting diode and the light sensitive transistor form light coupling, the measurement of the utility model eliminate the influence to the measurement from outer electromagnetic fields and ferromagnetism substance. The utility model has the practicability that the pipe type oil flow capacity sensor can be used for measuring the oil flow capacity of transparent or subtransparent mineral oil or vegetable oil in pipelines.
Description
The utility model relates to the sensor of a kind of duct type oil flow, is mainly used in the measurement of oily flow in various transparent or semitransparent mineral or the vegetable oil pipeline.
Existing oily flow sensor has two kinds of methods:
First kind is that the impeller blade with ferromagnetic property is installed in pipeline, and the fluxion strap moving vane of oil rotates.By being loaded on the hall probe on the tube wall, converting the rotation of blade to electric signal and send in measurement instrument.Though this mode can achieve the goal in application, pipeline will be used the nonmagnetic substance manufacturing, and sensor in service will influence measuring accuracy on every side as the random variation of ferromagnetic material or high-intensity magnetic field occurring.
Second kind is that shelves stream plate is installed in pipeline.The mobile drive plate washer of oil tilts, and drives instrument indicating mechanism by magnetic coupling principle.This mode is low because of sensitivity, only can do the observational measurement of oil flow.
Task of the present utility model provide a kind of sensitivity and the linearity higher, be not subjected to the duct type oil flow sensor that external electromagnetic field influences.
Technical solution of the present utility model is, light emitting diode and phototriode are pressed the photoelectricity coupling principle, is installed on the support of impeller both sides.On impeller shaft, impeller shaft is fixed on the axle support with nut impeller blade by Bearing Installation.The contact conductor of light emitting diode and phototriode causes measurement instrument from the base perforation.Fairlead seals admittedly with epoxy resin.Whole sensor is loaded in the oil stream pipeline by pedestal.In pipe, during oil flow, reflect the electric impulse signal of oily flow from phototriode output.
In the utility model, what circuit connected is characterized as, the light emitting diode positive pole is connected with the phototriode positive pole and is connected to the instrument positive supply, the light emitting diode negative pole is connected to the instrument negative supply by current-limiting resistance, the phototriode negative pole is connected to negative supply by pull-up resistor, and the output electric pulse signal of sensor is drawn from the tie point of phototriode and pull-up resistor.
The advantage of sensor described in the utility model is:
(1) impeller is not subjected to the braking action of magnetic force or mechanical spring in oil stream, thereby sensitivity and the linearity are higher.
(2) owing to adopted the photoelectricity coupling principle, got rid of the influence of external electromagnetic field interference to measuring accuracy.
(3) the phototriode output loading capability is strong, can connect with the counting Displaying Meter circuit that TTL or CMOS integrated circuit are formed easily.
The wiring layout that accompanying drawing 1 designs for the utility model, accompanying drawing 2 is sensor circuit figure.
Below in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail.
The label of each parts and title are as follows in the accompanying drawing 1: 1-impeller blade, 2-rivet, 3-impeller shaft, 4-bearing, 5-impeller blade trim ring, 6-LED support, 7-light emitting diode, 8-phototriode and axle bracket, 9-packing ring, 10-impeller shaft hold-down nut, 11-phototriode, 12-support gib screw, the solid seal ring epoxy resins of 13-electrode hole, 14-sensor base.
When in the oil line pipe oil flow being arranged, then blade 1 just rotates, the light that light emitting diode produces to the effect of phototriode with regard to switch-on and-off, like this since phototriode just send the voltage pulse signal that reacts oily flow the pipeline to measurement instrument from pull-up resistor R2.
Accompanying drawing 2 is the circuit diagram of light emitting diode 7 and phototriode 11, among the figure light emitting diode be connected to the instrument power anode after the positive pole of phototriode links to each other, the light emitting diode negative pole is connected with current-limiting resistance R1, the other end of resistance R 1 is connected to the instrument power negative terminal, the negative pole of phototriode is connected with pull-up resistor R2, and the other end of resistance R 2 is connected to the instrument power negative terminal.The potential pulse of reaction oil flow is by phototriode negative pole and the output of pull-up resistor point of contact A point.
