Safety & Maintenance
Safety Guidelines:
Release Residual Pressure: Always ensure that all pressure in the mud cup is fully released before opening to avoid sudden fluid ejection.
Use Approved Gases Only: Only Nitrogen or CO₂ should be used as the gas source; oxygen or other reactive gases are strictly forbidden.
Gradual Pressure Increase: Slowly ramp up pressure during tests to prevent damage to filter paper, gauges, or the mud cup assembly.
Avoid Overheating: Monitor the heating jacket and electrical controls to maintain proper temperature limits, preventing accidents or equipment damage.
Personal Protective Equipment (PPE): Always wear appropriate gloves, eye protection, and lab coats during operation.
Maintenance Recommendations:
Regular Inspection: Check all “O”-rings, hoses, and connections for wear or leaks before and after each use.
Lubrication: Clean and lubricate moving parts and seals to maintain smooth operation.
Filter Paper Replacement: Use fresh HTHP filter paper for each test to ensure accurate results and prevent contamination.
Electrical System Checks: Periodically inspect wiring, switches, and temperature control systems for any faults or damage.
Storage: Store the instrument in a clean, dry environment to prevent corrosion or degradation of components.
Following these safety and maintenance practices ensures consistent performance, reduces downtime, and enhances the longevity of the PP HTHP Filter Press.
