自吸泵的好处 The benefits of self-priming pumps 1、自吸泵的好处之一是它不需要安装在水池里面而是装在水池上面，避免了潜水泵常年浸泡在水池中容易被锈蚀或者由于密封件损坏而导致潜水泵电机进水而烧坏电机。 1, one of the advantages of self-priming pump is that it does not need to install inside the pool but in the water, avoid the submersible pump perennial soak in the pool are easy to be corroded or due to damage of seal submersible pump motor inlet and burn out. 2、自吸泵的好处还可以采用防爆电机的可以输送易燃易爆的液体，例如汽油（叶轮采用铜叶轮的自吸油泵）、酒精等液体。 2, the benefits of self-priming pump can also adopt the explosion-proof motor can carry inflammable and explosive liquid, such as gasoline (self-priming pump impeller with copper impeller), alcohol and other liquid. 3、自吸泵的好处之一还有可以采用柴油机驱动为动力的用于农田灌溉、应急抢险无电源的场所。 One of the advantages of a self-priming pump is the use of a diesel engine driven for irrigation, emergency rescue, and no power supply. 4、自吸泵还可以装在移动拖车上面或者大型电源泵车上面用于城市防汛抢险之用抽取城市积水之用。 Self-priming pumps can also be used on mobile trailers or in large power supply pumps for urban flood relief. 5、自吸泵第一次灌水后以后就不需要灌水，能把低处或者远处的液体抽吸到泵体里面来再排走，进口不需要安装底阀不像离心泵一样遇到液位比泵低的工况必须在进口管道装底阀，离心泵停机时间长了由于底阀密封性能不好进口管道里面的水回流之后下次启动还需要罐水，而且安装底阀之后还会影响离心泵的流量，而自吸泵就避免了此类现象，这也是使用自吸泵的好处之一。 After 5, self-priming pump water for the first time since there is no need to infuse water, to lower or the distance of the liquid inside the suction to the pump body to come again, don't need to install the bottom valve imports like centrifugal pump with liquid level is lower than pump operating mode must be at the inlet pipe of bottom valve, centrifugal pump long downtime due to bottom valve sealing performance is bad the inside of the inlet piping water back after the next start need water tank, and after the installation of bottom valve will influence the flow of a centrifugal pump, and the self-priming pump avoids this kind of phenomenon, this is also one of the benefits of using self-priming pump.
