LZD127 Mining Explosion-Proof and Intrinsically Safe Flowmeter Maintenance
The following are the key maintenance points for the LZD127 mining explosion-proof and intrinsically safe flowmeter, summarized based on its technical characteristics and underground working conditions:
I. Periodic Maintenance Items
‌Sensor Cleaning‌
Clean electrode and liner surface deposits (such as coal slurry water/viscous medium residue) quarterly using a soft brush and neutral cleaner (e.g., isopropyl alcohol). Avoid scraping with hard objects to prevent damage.
‌Explosion-Proof Structure Inspection‌
Check the smoothness of explosion-proof joint surfaces monthly (gap standard ≤0.15mm) and replace deformed seals promptly.
Check for loose connections in intrinsically safe circuits to ensure the explosion-proof marking Exd[ib]I meets requirements.

II. Calibration and Function Verification
‌Range Setting Calibration‌
Access the menu with a password to modify range units (e.g., m³/h). Enter the calibration password (default 1234) first.
Press the confirmation key for 1 second to complete parameter modification during remote settings.
‌Alarm Function Test‌
Simulate high and low limit scenarios to verify whether full-bin protection and alarm signals trigger normally.
