Pump Quality Test
The quality testing of water pumps in pet water dispensers typically includes the following key projects:
-
Performance Testing
-
Flow Rate & Lift Capacity: Measures water output volume per unit time and vertical pumping height to ensure proper circulation.
-
Energy Efficiency: Evaluates power consumption (e.g., 1.5W ultra-low energy) and check the deviation from the rated power.
-
-
Safety & Reliability Testing
-
Electrical Safety: Insulation resistance (>100MΩ), grounding continuity, and leakage current tests to prevent electric shocks.
-
Seal Integrity: Submersion and pressure tests to prevent leaks.
-
Material Safety: Verifies BPA-free certifications and NSF-approved components to ensure non-toxic water contact.
-
-
Noise & Vibration Testing
-
Acoustic Performance: Measures noise levels below 25dB (ultra-quiet models achieve ≤20dB) using calibrated equipment.
-
Vibration Analysis: Monitors vibration amplitude (typically <4.5mm/s) to assess mechanical stability and wear risks.
-
-
Durability Testing
-
Continuous Operation: Simulates 24/7 operation for ≥30 days to validate pump lifespan.
-
Environmental Stress: Tests performance under extreme temperatures(0-40℃) and humidity to ensure reliability.
-
-
Smart Functionality Testing
-
Filtration Efficiency: Assesses multi-layer filter systems (activated carbon, ion-exchange resin) for removing impurities, odors, and pathogens.
-
Dry-Run Prevention: Run the pump without water to simulate dry operation. A properly functioning pump should automatically shut down within 3-10 seconds. Gradually reduce water levels using a controlled drainage system to observe if the pump activates protection before complete dryness. Perform 50-100 consecutive dry-run shutdowns to assess mechanical and electrical durability
-
-
Compliance Testing
-
Certification Standards: Verifies compliance with CE, UL1018, GB/T 23105, and other regional safety/performance certifications.
-
Obtaining at least a one-year warranty commitment from the supplier for the water pump is crucial. It is particularly important to note that the dry-run protection feature is almost indispensable.
