1. Online trace oxygen analyzer is a device that can perform online real-time detection of oxygen concentration, which is suitable for many industries and fields, such as petrochemical, electric power, steel, metallurgy, etc. The following will introduce the use of online trace oxygen analyzer in detail.
Preparation
2. Open the chassis of the online trace oxygen analyzer and install it on the corresponding equipment. According to the requirements of different models of online trace oxygen analyzers, connect it to the corresponding instrument system, start the system, and detect whether it is normal.
3. Determine the sampling point location
Select a suitable sampling point location, which should be close to the source of oxygen to be measured and representative. For example, in petrochemical enterprises, the bottom of the reactor can be selected as the sampling point to ensure accurate measurement of oxygen concentration.
4. Install and connect the sampling probe
Online trace oxygen analyzers usually need to install special sampling probes, which can collect samples from the measured gas flow. The sampling probe should be installed at the determined sampling point, and the sample should be transported to the online trace oxygen analyzer through the pipeline for detection.
5. Calibrate the instrument
The online trace oxygen analyzer needs to be calibrated before it is put into use. The calibration process should be operated according to different models. Generally speaking, calibration is to determine its accuracy by testing at a specific oxygen concentration and correcting the instrument.
6. Start the test
Start the online trace oxygen analyzer system, adjust the sensitivity of the detector, and start the test. When the detected gas enters the instrument through the sampling probe, the instrument will measure the oxygen concentration and output the test results in real time.
7. Record data
For each test, the corresponding date, time, detection location, measurement value and other information should be recorded. The data of multiple tests can be used to study and analyze the changing trend of the concentration of the detected gas.
8.Maintenance
The online trace oxygen analyzer needs regular maintenance to ensure its normal operation. Maintenance includes cleaning the internal components of the instrument, replacing damaged parts, calibrating the instrument and upgrading the software. At the same time, according to the maintenance manual provided by the manufacturer, a corresponding maintenance plan should be formulated to better maintain the instrument.
It should be noted that the use of online trace oxygen analyzers needs to comply with the corresponding safety regulations, such as good ventilation and strict prohibition of smoking. During use, personnel should undergo special training and authorization, and receive relevant guidance and operations. If problems are found in the instrument or abnormal test results, it must be repaired and calibrated before the next test. In this way, the reliability and accuracy of the online trace oxygen analyzer can be guaranteed, bringing more benefits to industrial production.
