Description
Technical field
The present invention relates to a kind of automatic bubble counting system based on photoelectric technology.
Background technology
Often relate to equipment in many occasions such as commercial production, aeronautical and space technology, scientific experiments, for example: pipeline, container, heat interchanger, valve and vacuum envelope etc. with impermeability requirement.In order to guarantee the normal operation of this kind equipment, must carry out airtight test to it.At present, Chang Yong qualitative impermeability leak hunting method has: audition method, infusion method, soap water law, helium mass analyzer method etc.Since some application scenario, for example: hard sealed valve, allow to exist certain leakage rate, must take quantitative airtight test method this moment, mainly contains at present: tonometry, flowmeter survey method and bubble mensuration etc.Tonometry is the pressure variation by detected gas in the measuring system, and according to system volume conversion leakage rate, the leak detection process need be got rid of the influence of temperature variation for system gas pressure, when being used to detect the minute leakage of big system, require highly sensitive pressure transducer and long Measuring Time.The flowmeter survey method is mainly used in the bigger occasion of leakage rate, then is difficult to measure for the situation of tiny leakage.The bubble mensuration is the method for coming the quantificational expression tiny leakage by the number of bubbles of record certain hour internal leakage.Traditional bubble mensuration mainly relies on and manually counts bubble, not only consume manpower, and counting work dry as dust causes makeing mistakes easily, particularly surpasses 1Hz when (promptly surpassing 1 bubbles per second) when the bubble occurrence frequency, relies on naked eyes to be difficult to realize accurate counting.
Summary of the invention
The purpose of this invention is to provide a kind of automatic bubble counting system based on photoelectric technology.
It comprises draft tube, bubbler tube, glass measuring tube, measures agent, light emitting diode, dc constant voltage power supply, silicon photocell, amplifying circuit, data collecting card and computing machine, draft tube is through bubbler tube and glass measuring tube bottom connection, both sides, glass measuring tube middle part are respectively equipped with light emitting diode and silicon photocell, light emitting diode and dc constant voltage power supply join, and silicon photocell joins with amplifying circuit, data collecting card and computing machine successively.
The present invention can realize the automatic gauge number of bubbles, has simple in structure, the accurate and effective measurement range broad (0-10Hz of counting, be that 10 following bubbles of per second all can be measured), advantage such as reliable and stable, can be widely used in the quantitative measurment of tiny leakage and other need carry out the occasion of bubble counting.
Description of drawings
Accompanying drawing is based on the automatic bubble counting system structural representation of photoelectric technology.
Embodiment
As shown in drawings, the automatic bubble counting system based on photoelectric technology comprises draft tube 1, bubbler tube 2, glass measuring tube 3, measures agent 4, light emitting diode 5, dc constant voltage power supply 6, silicon photocell 7, amplifying circuit 8, data collecting card 9 and computing machine 10.Draft tube is through bubbler tube and glass measuring tube bottom connection, and both sides, glass measuring tube middle part are respectively equipped with light emitting diode and silicon photocell, and light emitting diode and dc constant voltage power supply join, and silicon photocell joins with amplifying circuit, data collecting card and computing machine successively.
Draft tube is used for the gas from source of the gas is caused bubbler tube.Bubbler tube one end links to each other with draft tube, and an end inserts glass measuring tube bottom, is used for bubbling.A certain amount of transparency liquid of splendid attire is as measuring agent in the glass measuring tube, and this measurements agent must not dissolved search gas, and for example: search gas can adopt water as the measurement agent during for helium.Light emitting diode is powered by the dc constant voltage power supply.Light emitting diode and silicon photocell are disposed in the following sustained height position of glass measuring tube liquid level, place the both sides of glass measuring tube respectively, the light-emitting area of light emitting diode is relative with the light-sensitive surface of silicon photocell, so that the light signal that the silicon photocell induction is launched by light emitting diode, and be converted into voltage signal output.Silicon photocell links to each other with amplifying circuit, and amplifying circuit is used to amplify the voltage signal of silicon photocell output, thereby reduces the influence of background interference signal for useful signal.The voltage signal of silicon photocell output enters computing machine by data collecting card after amplifying circuit amplifies.When bubble during by the measurement agent between light emitting diode and the silicon photocell, bubble causes that for the disturbance of the light signal that light emitting diode sends fluctuation appears in the silicon photocell output voltage signal, by computing machine the voltage signal that collects is carried out wave form analysis, the fluctuation that counting causes when measuring agent because of bubble, thus realize the automatic gauge number of bubbles.
During based on the operation of the automatic bubble counting system of photoelectric technology, at first connect source of the gas, and to open the dc constant voltage power supply be the light emitting diode power supply, make it luminous; Then, start computer data acquisition system, gather the voltage signal of also analyzing silicon photocell output, show automatically, write down and preserve total leakage number of bubbles and unit interval internal leakage number of bubbles in the certain hour, finish automatic bubble counting by computing machine.
When the automatic bubble counting system that uses based on photoelectric technology, note the selection of glass measuring tube internal diameter, if glass measuring tube internal diameter is much larger than bubble diameter, with cause bubble by the time to the disturbance deficiency of the light signal that light emitting diode sent, and then the fluctuation that causes the silicon photocell output voltage signal is not obvious, this will increase the difficulty that computing machine is analyzed voltage signal, influence accurate counting; Yet too small glass measuring tube internal diameter may limit the buoyance lift of bubble in measuring agent, even forms gas column in the glass measuring tube, can't carry out bubble counting.The diameter of bubbler tube formation bubble is all multifactor relevant with surface properties, orifice configuration and the size of bubbler tube material, measurement agent liquid level etc., can adjust the bubble of suitable size by test, and then the internal diameter of apolegamy glass measuring tube.
In addition, when carrying out the voltage signal analysis,, particularly reduce the influence of the background interference of 50Hz if at first utilize software that voltage signal is carried out filtering, can improve to bubble by the time voltage fluctuation that the causes correctness analyzed, and then effectively guarantee the accuracy of bubble counting.
