WP-1 Rapid Measurement Instrument for Coal Seam Gas Content

Product Introduction of WP-1 Rapid Measurement Instrument for Coal Seam Gas Content

The WP-1 rapid measurement instrument for coal seam gas content is designed based on the principle that the desorption rate of coal sample gas follows a power function relationship with time, and the gas desorption characteristic index V1 value is used to calculate the coal seam gas content and pressure. In the design, microcontroller control technology and advanced gas flow sensing technology are adopted, and the principle of resistance free trace gas flow measurement is used to make the coal sample desorption process closer to the natural desorption state of coal. To ensure the accuracy of the measurement results, numerical averaging is applied to the collected data in the software, making the instrument have the characteristics of simple circuit, small size, light weight, easy portability, and simple operation.

Instrument characteristics of WP-1 rapid gas content analyzer

The coalbed methane content analyzer is suitable for underground mining or excavation work faces in coal mines, quickly measuring the amount of gas desorption in the coal body. It can timely grasp the distribution of gas content (W) and gas pressure (P) in front of the work face, as well as the changes in important gas parameters such as anti outburst prediction indicators K1 and K2, forming a relatively complete and reliable set of prediction and forecasting techniques. Its features include short measurement time (the entire process takes 7 minutes, with 2 minutes of exposure and 5 minutes of desorption), no impact on normal working face, automatic completion of measurement, collection, calculation, storage, display, printing and other tasks, easy operation, time-saving and labor-saving, accurate and reliable, and the ability to predict multiple important gas parameters in one measurement. This provides a fast and concise measurement method and reliable scientific basis for predicting gas emission in production mines and for the rational development and utilization of gas resources. Similarly, the coalbed methane content analyzer is also suitable for laboratory research and testing work.
