耐用的自吸管中泵要安装底阀吗？
管中泵是否需要在自吸管中安装底部阀？常用的管中泵根据叶轮的旋转，液体流向蜗壳，使泵体在管道中形成真空。这样，自吸管中泵的单向阀打开，液体从进口吸入，通过叶轮通道排出。这就是自吸管中泵的工作原理？自吸管道中的泵的一个显著特点是使用时不需要注水。但是，当您第一次使用时，一定要记得把水倒进VAREM管中泵的泵腔中，因为管道中的泵体中没有储存液体。如果不第一次向泵体注水，管道中的泵就会空转，不仅吸不到液体，还会因空转而烧坏管中泵体的机械密封等附件，因此必须注意这一点。那么自吸管中泵是否需要安装底阀呢？01如果没有，情况如何？一般来说，无需安装底阀，因为一般情况下，VAREM管中泵的进口在自吸管道上都装有止回阀，也叫单向阀。这样，管中泵停了以后，管中泵里的液体就回不到原来的池里了，它就储存在管中泵里了，所以第二次用的时候就不需要加液体了，如果装了底阀怎么办？如果安装了底阀，效果会更好，因为如果单向阀有时损坏，会用底阀作为保证，避免空转，而且底阀安装后，VAREM管中泵在管道中的有效吸入也会得到有效保证！另一种特殊情况，但如果吸入高差过大，或吸入管直径过大，容积超过自吸管中泵管泵腔内储液量，则无法正常工作。此时，必须安装底阀，以保证自吸的安全和速度。
Do you need to install bottom valve in durable self priming pump?
Is it necessary to install bottom valve in self suction pipe for in pipe pump? According to the rotation of the impeller, the liquid flows to the volute, which makes the pump body form a vacuum in the pipeline. In this way, the one-way valve of the pump in the self suction pipe is opened, and the liquid is inhaled from the inlet and discharged through the impeller channel. This is the working principle of the pump in the self suction pipe? A remarkable feature of the pump in the self-priming pipeline is that it does not need to inject water when it is used. However, when you use it for the first time, be sure to pour water into the cavity of the pump in the varem pipe, because there is no liquid stored in the pump body in the pipe. If the pump body is not filled with water for the first time, the pump in the pipeline will run idle, not only can not absorb the liquid, but also the mechanical seal and other accessories of the pump body in the pipeline will be burned due to the idling, so we must pay attention to this point. So whether the pump in the self-priming pipeline needs to install the bottom valve? 01 if not, what's the situation? Generally speaking, there is no need to install the bottom valve, because in general, the pump inlet in the varem pipe is equipped with check valve, also known as one-way valve, on the self-priming pipe. In this way, after the pipe pump stops, the liquid in the pipe pump will not return to the original pool, and it will be stored in the pipe pump, so there is no need to add liquid when it is used for the second time. What if the bottom valve is installed? If the bottom valve is installed, the effect will be better, because if the check valve is sometimes damaged, the bottom valve will be used as a guarantee to avoid idling, and after the bottom valve is installed, the effective suction of the pump in the varem pipe will also be effectively guaranteed! In another special case, if the suction height difference is too large, or the diameter of the suction pipe is too large, and the volume exceeds the liquid storage in the pump cavity of the pump pipe in the self suction pipe, it will not work normally. At this time, the bottom valve must be installed to ensure the safety and speed of self-priming.
