1.對于吸沙泵來說，流量超載會導致電機負載扭矩過大，接著就是電機電流變大。
2.高揚程的吸沙泵用于低揚程環(huán)境中，即用額定轉(zhuǎn)速更快，扇葉更小的沙泵替代原本應該額定轉(zhuǎn)速不快，扇葉更大的泵。
3.對于一臺高揚程的吸沙泵，若是實際情況不需要那么高的壓力，那么沙泵就會在低揚程下運行，此時吸沙泵的流量會比額定的高揚程下的流量大，這時的功率也會比額定的高揚程時高，所以容易超載。
1 for suction sand pump, flow overload will lead to motor load torque is too large, then the motor is large.

2. High lift sand suction pump for low lift environment, namely by the rated speed faster, fan leaves smaller sand pump instead of originally should rated speed is not fast, the fan leaves more of the pump.

. for a high lift the sand suction pump, if the actual situation don't need such a high pressure, then sand pump will be in low head run, when the suction sand pump flow will larger than the rated high lift flow, when the power will also is higher than the rated high on the head, it is easy to overload. |
