通过用户调查,发现很多工厂水泵的吸入装置不符合要求,吸入高度过大,吸入管道过长,直径偏小,吸入管路上弯头、闸阀等阻力件过多等原因,导致吸入管道阻力过大,造成水泵在汽蚀工况下运行。这样既使水泵运行效率降低,电力浪费,也使水泵转子很快损坏。 Through the user survey found that many factory pumps inhalation device does not meet the requirements of inhalation height is too large, suction pipe is too long, the diameter is small, the suction pipe elbow, gate valve and other excessive resistance and other reasons, leading to suction pipe resistance is too large , Causing the pump to operate under cavitation conditions. This will not only reduce the efficiency of the pump operation, power waste, but also to pump rotor damaged quickly.
