离心泵用的吸水胶管,用久了会自动脱胶,使水泵不能正常工作。但怎样辩认呢?只要细心观察就会发现,如果是异物堵塞了吸水管,多次起动水泵,其表现形式都是一个样子,不出水或少出水。若是吸水管脱胶了,第二天再起动水泵,刚开始出水正常,但一会儿出水就会减少,甚至不出水了。如果这时停泵后再立即起动,泵刚一出水,水量就会变小,停泵的时间延长则水泵能出水的时间也随之延长,但结果一样,少出水或不出水。发现这种现象后,立刻拆下吸水管,用手电筒往里照或对着太阳看,就会发现脱胶处呈鼓起的形状。吸水胶管内层脱胶后可用弹簧撑起来,弹簧两端用细铁丝牵着,铁丝固定在法兰盘上,安装时需用厚胶垫;也可用铲
Centrifugal pump suction hose, with a long time will automatically degumming, so that the pump can not work properly. But how to identify it? As long as careful observation will find that if it is a foreign body clogged suction pipe, pump several times, its performance is a form of appearance, no water or less water. If the pipe degumming, and then start the pump the next day, just started normal water, but for a while the water will be reduced, or even out of the water. If you stop the pump immediately after this start, the pump just a water, the water will be smaller, stop the pump longer the water pump can also extend the time, but the same result, less water or no water. Found this phenomenon, immediately remove the suction pipe, flashlight inwards or against the sun to see, you will find a degumming was a bulging shape. After the inner layer of absorbent hose degumming can be used to hold up the spring, both ends of the spring with a thin wire holding wire fixed to the flange, the installation requires thick rubber pad; also shovel
