At this time, is full of water pumps, if the long run, would lead to rising temperature in the pump, pump shell, the bearings will be fever, severe heat may make the body deformation, known as the "stuffy head," at this time Head to the maximum value, when the valve to gradually open, traffic will gradually increase, shaft power also slow the increase.

此时水泵里是充满水的，如果长时间的运行，会导致泵内温度不断升高，泵壳，轴承会发热，严重时可能使泵体热力变形，我们称为&闷水头&，此时扬程为最大值，当出水阀逐渐打开时，流量就会逐渐增加，轴功率亦缓慢的增加。

An improvement on the die casting technology of aluminium hub includes drilling hole at the position of die, where the function of die is not affected, for preventing gas from coming into molten aluminium, mounting safety valve to the exhaust opening of die casting case for keeping proper pressure to save electricity and shorten die casting time, and increasing the water-flowing area of cooling disk or ring for higher cooling effect.

一在不影响模具本身功能部位钻孔增加排气通道，解决了压铸过程中产生的气体进入铝水问题。可使铝轮减少气孔。在压铸机箱体排气口部位，安装安全阀，能使压铸机箱体内保持适当的压力，工作时少进气、少排气，起到节电不堵浇口，缩短压铸时间，提高产量。冷却盘、冷却环改进后，增加了过水面积，提高了冷却效果。
