1.對(duì)于吸沙泵來(lái)說(shuō)，流量超載會(huì)導(dǎo)致電機(jī)負(fù)載扭矩過(guò)大，接著就是電機(jī)電流變大。
2.高揚(yáng)程的吸沙泵用于低揚(yáng)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(yīng)該額定轉(zhuǎn)速不快，扇葉更大的泵。
3.對(duì)于一臺(tái)高揚(yáng)程的吸沙泵，若是實(shí)際情況不需要那么高的壓力，那么沙泵就會(huì)在低揚(yáng)程下運(yùn)行，此時(shí)吸沙泵的流量會(huì)比額定的高揚(yáng)程下的流量大，這時(shí)的功率也會(huì)比額定的高揚(yáng)程時(shí)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. |
