What is the reason for the error in the concentration display of the nitrogen gas alarm?

Over the years, nitrogen accidents in enterprises have repeatedly occurred, and can generally be summarized as nitrogen suffocation, nitrogen compressor explosion, ultra-high nitrogen oxygen content, low-pressure gas cutoff caused by users, and nitrogen pipeline low-temperature overpressure explosion accidents.

Nitrogen is a colorless, odorless, and odorless inert gas. It is not harmful to the human body, but increasing the nitrogen content in the air will reduce the oxygen content, making it difficult for people to breathe. If you inhale pure nitrogen, you will suffocate due to severe hypoxia. Installing a nitrogen gas alarm can effectively prevent and prevent accidents such as explosion and poisoning caused by nitrogen leakage.

Many companies will encounter problems such as errors in the display concentration of the nitrogen gas alarm during use. Based on the years of experience in the technical department, a summary is made.

Cause Analysis:

1.The nitrogen concentration does not meet the requirements during calibration;

2.The sensor range is set incorrectly;

3. Sensor aging

Solution:

1.Recalibrate with qualified sample gas;

2.Reset the sensor range;

3.Replace new sensors;

Hydraulic Tongs Use Die

Die is the core part of hydraulic tongs, and also a vulnerable part. Hydraulic tongs are wellhead tools used in the oil field. They are used to fix drill pipe when exploring for oil. The die is directly in contact with the drill pipe and produces friction, thus fixing the drill pipe.
