CWH20 Coal Seam Gas Content All-in-One Measuring Instrument Features and Technical Parameters
I. Functional Features
1. Fully Integrated Downhole Testing Process
? Enables complete downhole operations including coal sample sealing and crushing, natural gas desorption, crushing desorption, and loss/residual gas content measurement without the need for sample transfer
? Eliminates traditional drainage method for gas measurement, avoiding tank opening and transfer operations, and mitigating gas leakage risks
2. Intelligent Data Management System
? Equipped with a 7-inch industrial-grade touch screen, supports real-time generation of structured reports downhole, automatic data storage, and visual presentation
? Wireless connectivity via mining-intrinsic safety mobile APP, automatic collection of desorption volume/time data, built-in mathematical model for intelligent estimation of gas loss
3. High-Safety Power System
? Features overcurrent-protected intrinsic safety power supply, supports one intrinsic safety power output, adaptable to complex downhole conditions
? Utilizes quick-connect pneumatic crushing device, with air-driven mechanical sealed crushing efficiency increased by 40%, single crushing time ≤5 minutes
