Fully Automatic Initial Velocity of Gas Emission Measuring InstrumentWFC-III

Product Introduction

The Initial Velocity of Gas Emission Measuring Instrument (hereinafter referred to as the instrument) is a fully automatic experimental device primarily used for measuring the key indicator in coal and gas outburst risk prediction—the initial velocity of gas emission ΔP. It is designed to investigate and study the gas emission characteristics of coal, continuously measuring the initial velocity of gas emission within 0-60 seconds after adsorbing high-concentration methane under one atmospheric pressure.

The core components of the Initial Velocity of Gas Emission Measuring Instrument utilize imported sensors, fully achieving computer detection and control. The entire testing process can be completed simply by pressing corresponding keys as prompted by the computer interface, eliminating human-induced errors in experimental results. Test results are printed in the form of curve reports.

Product Performance

This equipment is designed in accordance with the AQ1080-2009 standard "Method for Determination of Initial Velocity of Gas Emission (ΔP) of Coal." The experimental process is fully intelligent and automated, with smart calculation of data results, simple operation, and improved work efficiency.

The equipment's sensors and electromagnetic valves use imported components, ensuring excellent system airtightness and scientifically accurate test results.

The main unit design complies with safety ergonomic principles, featuring an integrated design that reduces manual operations and ensures a highly safe and reliable experimental process.
