无底阀抽水是一项充分挖掘排灌设备潜力的有效措施。去掉底阀后流量可增加10～30%,并可避免突然停机时“水锤”的危害。下面简介我区无底阀抽水的几种简便方法: 1.自制简易抽气设备,代替真空泵。简易抽气设备的工作原理和打气筒相同。此设备有机动和手动两种。机动的转速高,抽气快,一般用在吸程较高的大口径水泵上。如无专用动力,可用排灌设备本身的动力带动,但须注意吸气孔应升在水泵出水管或出水管口拍门上。手动的抽气慢,多用在
Bottomless valve pumping is an effective measure to fully tap the potential of irrigation and drainage equipment. Remove the bottom valve after the flow rate can increase 10 ~ 30%, and to avoid sudden shutdown “water hammer ” of the hazards. Here are some simple ways to pump my bottomless valve: 1. Simple self-made pumping equipment, instead of a vacuum pump. Simple pumping equipment works and pump the same. This device has two kinds of mobile and manual. Motorized high speed, pumping fast, generally used in the suction stroke of the large-caliber pump. If there is no special power, irrigation and drainage equipment can be driven by their own power, but be aware that the suction hole should be lifted in the pump outlet pipe or outlet port pat. Manual pumping slow, used in more
