Abstract
The utility model relates to a quick restoration device of an infrared tail gas analyzer for an automobile, belonging to the technical field of environment protecting detection equipment. The utility model relates to the quick restoration device of an analyzer used for detecting CO and HC compounds in the tail gas of the automobile. The utility model is formed by connecting a probe, a gas storing chamber, a CO detecting unit, an HC detecting unit, an amplifying unit, an analogdigital converter, a microprocessor and a meter display screen. The utility model is characterized in that an exhaust pump is arranged on a gas outlet of the gas storing chamber. The utility model has the advantages of simple structure and high work efficiency, and the concentration of the CO and the HC of the tail gas of the automobile can be rapidly detected.
Description
The quick resetting means of a kind of infrared ray automobile exhaust analyzer belongs to the environmental protection tests equipment technical field, is a kind of quick resetting means of analyser that is used for detecting vehicle exhaust CO, HC compound test.
Existing infrared ray automobile exhaust analyzer, form by CO and two detecting units of HC, when tail gas is detected, make the analyser probe that vehicle exhaust is imported air storage chamber by auto exhaust pressure, by two detecting units of CO, HC infrared energy is converted to electric signal, enter amplifying unit and amplify, become electrical signal conversion digital form to enter microprocessor by analog to digital converter again.As not containing two kinds of gases of CO, HC in the gas container, then meter reading is zero, as contains this two kinds of gases, and then instrument demonstrates the concentration readings of CO and HC.After exhaust analyzer is finished trace routine comprehensively, still there is certain density waste gas in the air storage chamber, the instrument zero resetting device need be waited for five minutes or the longer time, waits the waste gas in the air storage chamber all just to return zero after the outflow, detection efficiency reduces greatly like this.
The purpose of this utility model provides a kind of quick resetting means of infrared ray automobile exhaust analyzer that waste gas in the air storage chamber is discharged fast, to overcome the deficiencies in the prior art.
The purpose of this utility model is finished like this: it is formed by connecting by probe, air storage chamber, CO detecting unit, HC detecting unit, amplifying unit, analog to digital converter, microprocessor, instrument display screen, one natural gas outlet is arranged on the air storage chamber, on the gas outlet of air storage chamber, be connected with off-gas pump, by driven by motor, this motor power-supply wire through electromagnetism adsorb switch, the electric pulse device is connected with the tail end line of analog to digital converter.
Accompanying drawing is a structural representation of the present utility model
Describe in detail below in conjunction with accompanying drawing
1 is probe of the present utility model among the figure, probe 1 is communicated with air storage chamber 2 through conduit, one natural gas outlet 11 is arranged on the air storage chamber 2, air storage chamber 2 is communicated to CO detecting unit 3, HC detecting unit 4 by conduit, converts electric signal to, after amplifying unit 5 amplifies, output to analog to digital converter 6, convert digital signal to, enter microprocessor 8, output to display screen 9 after the processing; The gas outlet 11 of air storage chamber 2 is communicated with off-gas pump 12, and off-gas pump 12 is by driven by motor, and motor power-supply wire adsorbs the tail end line that switch, electric pulse device are connected to analog to digital converter through electromagnetism.When detecting CO, HC, analyser finishes, after instrument display screen demonstrates the concentration readings of two indexes, this moment, microprocessor 8 was transmitted back to signal the tail end line of analog to digital converter, again by terminal induction electrical pulse device 7, make 10 absorption of electromagnetism absorption switch, make power connection, machine operation drives the off-gas pump exhaust.After the waste gas in the air storage chamber disappeared, the index of instrument display screen returned zero, the induction of electric pulse device non-transformer, and the power supply of electromagnetism absorption switch is cut off, and stops exhaust.
This pass on the basis of existing infrared ray automobile exhaust analyzer, has increased by an off-gas pump with novel on air storage chamber, detection speed is improved greatly, thereby has improved detection efficiency.
