During pump factory acceptance, which key parameters should be checked in performance tests and to what standard?
• Perform performance test per ISO 9906 or GB/T 3216, confirming flow, head, and efficiency.
• Check flow-head curve deviation from datasheet, typically within ±5%.
• Measure shaft power and efficiency; efficiency not below 95% of guaranteed value.
• Conduct NPSHr test and check vibration per ISO 10816.
• Record mechanical seal leakage and bearing temperature rise for acceptance.
• Check flow-head curve deviation from datasheet, typically within ±5%.
• Measure shaft power and efficiency; efficiency not below 95% of guaranteed value.
• Conduct NPSHr test and check vibration per ISO 10816.
• Record mechanical seal leakage and bearing temperature rise for acceptance.
