-
Installation Guidelines for Precision Fit and Safety
1. Ensure alignment with the pump cylinder bore before securing the piston.
Misalignment can lead to lateral stress and edge chipping during reciprocation.
2. Avoid direct impact or force during installation.
Use soft-jaw tools and avoid hammering or press-fitting to prevent microcrack formation.
3. Inspect sealing interfaces and sleeves before assembly.
Damaged seals or debris may compromise tightness and affect dosing accuracy.
-
Pre-Operation Checks Before System Start-Up
1. Conduct visual inspection of the ceramic surface.
Look for cracks, scratches, or coating residue before engaging the piston in any cycle.
2. Verify correct fluid compatibility with zirconia ceramics.
Avoid unverified chemical blends that may contain fluorides or reactive halogens.
3. Calibrate stroke displacement and monitor stroke smoothness.
Inconsistent motion or abnormal noise may indicate improper alignment or seal deformation.
-
Routine Maintenance and Monitoring Practices
1. Clean the piston regularly with neutral pH solutions.
Acidic or alkaline cleaners may cause seal degradation and reduce system lifespan.
2. Monitor stroke frequency and operating load trends.
Excessive vibration or friction may indicate misalignment or contamination inside the pump.
3. Inspect and replace seals and sleeves as needed.
Seal fatigue or swelling can lead to piston scoring or dosage instability.
-
Storage and Handling Recommendations
1. Store pistons in their original foam-protected packaging.
This helps maintain cleanliness and protects against accidental impact.
2. Avoid high-humidity or chemically active environments during storage.
Condensation or vapor exposure may affect surface polish and dimension.
3. Label and track pistons by batch for quality traceability.
Proper inventory records improve reordering, batch analysis, and performance validation.
