Learn from the advanced practices of the *Brothers section; there are prizes for correct answers – every response earns a reward, allowing us to grow and mature through these Q&A sessions. Fill in the blanks: When the absolute pressure at the pump inlet is ( ) than the saturated vapor pressure of the liquid, the liquid will ( ) at the pump inlet, resulting in a large number of bubbles that strike the impeller, pump casing, and pump body, causing vibration and abnormal noise. Meanwhile, the pump’s flow rate, head, and efficiency all decline sharply; this phenomenon is known as the pump’s ( ) phenomenon.
When the absolute pressure at the pump inlet is (lower than) the saturated vapor pressure of the liquid, the liquid boils at the pump inlet, generating numerous bubbles that strike the impeller, pump casing, and pump body, causing vibration and abnormal noise. Along with this, the pump’s flow rate, head, and efficiency all decline sharply; this phenomenon is known as pump cavitation.
