自来水金沙js5官网在线加压前要排气的原因你知道吗?

  为什么自来水金沙js5官网在线每次压前都要排气?
  Why does the water gas booster pump exhaust before each pressure?
  自来水增压泵一般采用离心泵。
  The water booster pump generally adopts centrifugal pump.
  离心泵的工作原理:由于叶轮不断旋转的泵壳体装满水,在叶轮叶片之间的水做离心运动在离心力的作用下,并冲到住房以一定的速度和压力,和流入水出口管道泵通过流道的住房;同时,叶轮的部分形成真空。在常压作用下,水从吸入口管流入叶轮部位,填满真空区域。水流经叶轮部分与离心力作用,并通过壳体进入泵的出口管道。这样,只要吸入管路能坚持水的补偿和叶轮的连续转动,就完成了水泵的输送过程。

  Working principle of centrifugal pump: because the pump shell with continuous rotation of impeller is full of water, the water between the impeller blades makes centrifugal movement under the action of centrifugal force, and rushes to the housing with a certain speed and pressure, and flows into the housing where the water outlet pipeline pump passes through the flow channel; at the same time, the center part of the impeller forms a vacuum. Under the action of atmospheric pressure, water flows into the center of impeller from the suction pipe and fills the vacuum area. The water flows through the center part of the impeller and the centrifugal force, and enters the outlet pipe of the pump through the shell. In this way, as long as the suction pipeline can adhere to the water compensation and the continuous rotation of the impeller, the transmission process of the pump is completed.
  所以增压泵每次进水前都要加压排出空气,让水进入泵内,使叶轮溢流进水。
  Therefore, the booster pump should be pressurized to discharge air before each water inlet, so that the water can enter the pump and make the impeller overflow.
  方便的解决办法是找到一种泵停后的方法,泵还坚持水,空气不进入,更有用的方法是安装底部的阀门。
  The convenient solution is to find a way to stop the pump. The pump still insists that water and air do not enter. The more useful way is to install the valve at the bottom.
