To ensure every Bangwei rotary lobe pump delivered to customers achieves exceptional reliability and performance consistency, Bonve enforces a stringent quality control system covering design verification, material management, precision machining, and full-process testing. Prior to shipment, all products must pass the following core validation procedures:
I. Comprehensive Testing
Flow Test: Operate pump at rated conditions; record output via calibrated flow meters; verify compliance with design parameters.
Pressure Capability: Gradually increase pressure to specified multiples; inspect sealing integrity under high pressure.
Power & Current Monitoring: Track motor input power and three-phase current; assess energy efficiency alignment.
Noise Assessment: Measure operational noise in standardized environment; evaluate against acoustic norms.
Vibration Analysis: Monitor vibration signals at key bearings; determine mechanical stability via spectrum analysis.
Mechanical Seal Leakage: Visually inspect seal interface; confirm leakage meets "moist but not dripping" industry criteria.
NPSHr Verification: Induce cavitation by adjusting inlet pressure; record critical cavitation thresholds.
Volumetric Efficiency: Calculate efficiency via theoretical displacement vs. measured flow; validate against design targets.
II. Visual Inspection
• Surface Integrity: Examine castings/machined surfaces for defects.
• Assembly Compliance: Verify fastener torque markings and protective installations.
• Identification: Check nameplate parameters for accuracy and legibility.

III. Hydrostatic Test
• Pressure Loading: Inject test liquid into sealed cavity; apply specified pressure multiples.
• 60-Minute Sustained Pressure: Maintain target pressure for structural integrity verification.
• Acceptance Criteria: Zero leakage or permanent deformation.
IV. Full-Machine Performance Test
• 120-Minute Continuous Operation: Run at rated conditions with water medium.

• Parameter Monitoring: Periodically record flow, pressure, and temperature data.
• Stability Evaluation: Confirm absence of abnormal fluctuations.
• Post-Test Inspection: Disassemble to examine wear on critical friction pairs.
V. Quality Certification
• Data Documentation: Generate time-parameter correlation curves and checklists.
• Dual-Signature Approval: Joint validation by QC engineers and client representatives.
• Non-Conformance Handling: Implement corrective actions until compliance is achieved.
