一、自动排液装置是否节电一般过滤系统的设计,出于减少建设投资的原因,过滤机的安装位置较低。进入气水分离器的滤液,必须用离心泵强制抽出(图la)。由于专门设置了离心泵,消耗动力。如果安装自动排液装置,取消离心泵(图lb)是否能达到节电的目的呢?先看一下自动排液装置的原理。以浮选筒式自动排液装置为例(图2),当杠杆2和浮筒5处于图中所示位置时,左滤液罐内喉管被封闭,空气阀3被顶起,空气进 First, the automatic drainage device is power-saving General filter system design, out of reasons for reducing construction investment, filter installation location is low. The filtrate entering the gas-water separator must be forcibly withdrawn by a centrifugal pump (Figure 1a). Due to set up a centrifugal pump, consume power. If the installation of automatic draining device, cancel the centrifugal pump (Figure lb) can achieve the purpose of saving it? First look at the principle of automatic draining device. Taking the flotation tank automatic drain device as an example (Figure 2), when the lever 2 and the float 5 are in the position shown in the figure, the throat of the left filtrate tank is closed, the air valve 3 is jacked up, air enters
