Problems solved by technology

[0002] At present, the detectors used in oil and gas detection in the market generally cannot achieve long-term detection. First, because PID sensors are generally used for oil and gas detection, the sensitivity will decrease with long-term detection, and the detection response time will become longer. After the detection, when the content of interstitial molecules in the air increases, it may cause false alarms
Second, because some manufacturers adopt the pump-suction online detection method, the suction pump blocks the water inlet, etc., resulting in slow detection response speed and low detection accuracy.

Embodiment 2

[0029] Working principle of the present invention: the present invention adopts 12V-24VDC DC power supply for power supply, and adopts bright LED digital tube display. And the infrared sensor is used as the detection original. It is well known that the infrared sensor has the characteristics of long service life, fast response speed, and small drift. The present invention formally takes these advantages into account and expands and extends the service life of the detection device on this basis. The present invention is equipped with two air pumps, one for normal suction and one for reverse blowing. It is also equipped with a high-speed, high-precision pressure sensing device to detect changes in the internal pressure of the air circuit in real time. If the pressure is abnormal, it will stop the forward air pump urgently to stop the air pumping action, and start the reverse air blowing pump to realize the reverse air blowing operation. The foreign matter inside the gas path is...

Embodiment 3

[0031] In the present invention, the power conversion unit has three power conversions, respectively converting the main power to 9V, 6V and 5V. The main system is powered by 5VDC power supply, and the air pump is powered by 6VDC power supply controlled by the main control part. The infrared sensor part is powered by 9VDC power supply.

Description

technical field [0001] The invention relates to an oil gas detection device with intermittent back blowing and pumping function. Background technique [0002] At present, the detectors used in oil and gas detection in the market generally cannot achieve long-term detection. First, because PID sensors are generally used for oil and gas detection, the sensitivity will decrease with long-term detection, and the detection response time will become longer. After the detection, when the content of intervening molecules in the air increases, it may cause false alarms. The second is that some manufacturers adopt the pump-suction online detection method, which causes the suction pump to block the water inlet and other phenomena, resulting in slow detection response speed and low detection accuracy. [0003] It can be seen that it is particularly important to introduce that the present invention relates to an oil and gas detection device with intermittent blowback pumping function. ...
