b.双吸泵叶轮的两侧同时吸入液体，如图1-12所示。按导叶机构的形式a.蜗壳式泵具有像蜗牛壳形状的离心泵，单级泵大多是这种形式。b.导叶式泵在叶轮外围安有几个固定导叶片的泵即为导叶式泵(图1-13)。在早期，这种泵叫透平泵。多级泵大多是这种形式。按泵体接缝形式a.具有水平接缝的泵(中开式)通过泵轴中心线的水平面上开有泵体接缝的泵(图1-12)。具有垂直接缝的泵垂直于泵轴中心线的面上安装泵盖的泵。

一些大型事故的发生就在于系统对出现小事故后根本无法在短时间内排除险情而导致的。鉴于污泥干化系统的投资规模，还必须考虑出现极端性事件（如整厂停电、自动安全系统失灵等）时的安全应变能力。干燥工艺操作问题干泥返混进料泥饼的含固率变化范围较大，一般均在2%~25%之间。这给大多数污泥干化设备带来了难题，这些系统无法直接处理含固率低于6%的污泥。解决办法就是采用干返混，将大量已经干燥到9%以上的细颗粒返回到系统中进行混合。

使用不锈钢反应釜怕出现的就是粘壁。在使用反应釜设备时一旦出现粘壁，将严重影响反应釜的工作。所以要求大家在使用不锈钢反应釜时一定要正确操作，避免粘壁情况出现。不过还有一些工艺因素导致的粘壁是很难避免的。通常有四个工艺因素会导致不锈钢反应釜粘壁：原料因素因尿素中硫酸盐含量过高，当在树脂缩聚反应的后期加入尿素时，就相当于加入了固化剂，促使树脂快速交联成网状结构，若处理不及时，则会使树脂固化在反应釜内，在生产中应选用标准的工业用尿素原料，使尿素中的硫酸盐含量限制在.1%以下。

仪器设备：粗蛋白测定仪、样品粉碎机或研钵、分样筛、分析天平、消煮炉或电炉、滴定管、凯氏烧瓶、凯氏蒸馏装置、锥形瓶、容量瓶、消煮管。试样的选取和制备：选取具有代表性的试样用四分法缩减至2g，粉碎后全部通过4目筛，装于密封容器中，防止试样成分的变化。分析步骤试样的消煮：称取试样.5～1g（含氮量5～8mg）准确至.2g，放入凯氏烧瓶中，加入6.4g混合催化剂，与试样混合均匀，再加入12mL硫酸和2粒玻璃珠，将凯氏烧瓶置于电炉上加热，开始小火，待样品焦化，泡沫消失后，再加强火力（36～41℃）直至呈透明的蓝绿色，然后再继续加热，至少2h。
