1.对于吸沙泵来说，流量超载会导致电机负载扭矩过大，接着就是电机电流变大。

2.高扬程的吸沙泵用于低扬程环境中，即用额定转速更快，扇叶更小的沙泵替代原本应该额定转速不快，扇叶更大的泵。

3.对于一台高扬程的吸沙泵，若是实际情况不需要那么高的压力，那么沙泵就会在低扬程下运行，此时吸沙泵的流量会比额定的高扬程下的流量大，这时的功率也会比额定的高扬程时高，所以容易超载。

1 for suction sand pump, flow overload will lead to motor load torque is too large, then the motor is large.

2.高扬程的吸沙泵用于低扬程环境中，即用额定转速更快，扇叶更小的沙泵替代原本应该额定转速不快，扇叶更大的泵。

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.
