抽沙船工作中造成吸沙泵發(fā)熱的原因
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。
Causes of fever caused by sand suction pump sand pumping work
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, with rated speed faster, sand pump replacement fan should have smaller rated speed faster, more fan pump.
3 for the sand suction pump a high lift, if the actual situation does not require high pressure, then the sand pump will run in low head, sand suction pump flow than high lift under the rated flow at this time, when the power will be higher than the rated head high, so easy overload. |
