泵打量不好？ 泵抽空 ＝ pump cavitation 泵打量不好 ＝ loss of pump capacity/unstable pumping/drops in pump's efficiency cavitation means that cavities or bubbles are forming in the liquid that we're pumping. these cavities form at the low pressure or suction side of the pump, causing several things to happen all at once: 1. the cavities or bubbles will collapse when they pass into the higher regions of pressure, 2. causing noise, vibration, and damage to many of the components. 3. we experience a loss in capacity. 4. the pump can no longer build the same head (pressure) 5. the pump's efficiency drops.查看更多
