Guonuo's after-sales team addresses the installation issues of underground explosion-proof electronic belt scales. These scales, designed for use in hazardous and explosive environments in coal mines, provide continuous dynamic weighing while ensuring excellent explosion-proof performance. They offer accurate real-time and cumulative production data for coal enterprises, serving as a vital source of data for production monitoring.
However, installing these scales in underground mines is more challenging than in regular environments due to factors such as mine conditions, production constraints, and conveyor specifications.
Recently, Guonuo's after-sales engineers successfully installed four underground explosion-proof electronic belt scales despite encountering various challenges. After multiple calibrations, all four scales performed within the acceptable error range, meeting user accuracy requirements. The service included installation guidance, sensor wiring and calibration, software installation and debugging on the host computer, instrument installation, software debugging, and user training to ensure stable and reliable operation and independent user management.
Challenges in on-site installation coordination were overcome. Typically, belt scale installation involves selecting the installation site, modifying idler rollers, assembling the scale frame, and then conducting debugging.
However, upon arrival, the engineers found the mine in full operation, making it difficult to coordinate both personnel and time. To expedite the process, they prioritized the installation of the host computer software.
Through effective communication, they resolved wiring issues and completed the layout of power lines and 485 signal lines. With meticulous coordination, they utilized the daily two-hour maintenance window to modify and install the larger and more difficult-to-install belt scale idler rollers and mechanical components, along with preparing the round pipe modifications.
Issues with sensor-instrument connectivity were also resolved. Within the limited daily maintenance hours, it took four days to complete the belt scale transmission lines, construct outdoor enclosures to protect against weather, connect the sensors to the instruments, power up the instruments, and conduct zero-point calibrations.
During the debugging process, a problem was identified with a 500KG sensor's connection to the instrument, showing zero millivolt reading. After adjusting the screws and ruling out installation or connection issues, the sensor was replaced with a new one of the same capacity and address 04.
Ultimately, all belt scales were installed, calibrated, and successfully communicated with the host computer. Calibration tests confirmed seamless communication between the scale instruments, sensors, and the host computer.
Following the completion of debugging, the scales were put into operation, demonstrating consistent communication and measurement accuracy within the acceptable range.
Installing electronic belt scales, especially underground explosion-proof ones, often presents uncontrollable challenges that require highly skilled and experienced after-sales personnel. Guonuo's after-sales engineers, with their professional training and extensive project experience, are adept at resolving on-site installation and debugging issues, ensuring proper installation and long-term value of the scales.
