ESP acceptance test FAIL at +54% vs the curve

Post by shingis10 »

Good evening.

We ran acceptance tests on an ESP. We put an 80-size unit on the stand. The performance curve looks ideal, but the final result says *REJECTED*.

The deviation from rated capacity is +54%. Please explain why the curve looks fine while the test report says the unit is not acceptable.

Добрый вечер! Приёмо сдаточные испытания ЭЦН. Установили 80-ку. По графику лежит идеально, но показывает итог НЕГОДЕН. Отклонение от номинальной производительности +54%. Объясните почему по графику все в идеале а протокол не годен
