2、必须满足介质特性的要求。

对输送易燃、易爆有毒或贵重介质的泵，要求轴封可靠或采用无泄漏泵，如磁力驱动泵、隔膜泵、屏蔽泵对输送腐蚀性介质的泵，要求对流部件采用耐腐蚀性材料，如AFB不锈钢耐腐蚀泵，CQF工程塑料磁力驱动泵。

闸阀,截止阀,球阀,蝶阀,止回阀,安全阀,减压阀,疏水阀,电动蝶阀,气动蝶阀,电动球阀,气动球阀,电动截止阀,电动闸阀,电动调节阀,气动调节阀,水利控制阀,水泵,管道离心泵,消防泵,磁力泵,不锈钢化工泵,化工泵,衬氟离心泵,潜水排污泵,管道排污泵,液下泵,液下排污泵,螺杆泵,自吸无堵塞排污泵,氟塑料离心泵,气动隔膜泵,电动隔膜泵,多级管道泵,多级离心泵,耐腐蚀泵,单级单吸化工离心泵,隔膜气压罐,控制柜,自动搅匀潜水排污泵,变频无负压供水设备.变频全自动消防稳压供水设备对输送含固体颗粒介质的泵，要求对流部件采用耐磨材料，必要时轴封用采用清洁液体冲洗。

3、机械方面可靠性高、噪声低、振动小。

4、经济上要综合考虑到设备费、运转费、维修费和管理费的总成本最低。

5、离心泵具有转速高、体积小、重量轻、效率高、流量大、结构简单、输液无脉动、性能平稳、容易操作和维修方便等特点。

因此除以下情况外，应尽可能选用离心泵：有计量要求时，选用计量泵扬程要求很高，流量很小且无合适小流量高扬程离心泵可选用时，可选用往复泵，如汽蚀要求不高时也可选用旋涡泵.扬程很低,流量很大时,可选用轴流泵和混流泵。

介质粘度较大（大于650~1000mm2/s）时，可考虑选用转子泵或往复泵（齿轮泵、螺杆泵）介质含气量75%，流量较小且粘度小于37.4mm2/s时，可选用旋涡泵。

对启动频繁或灌泵不便的场合，应选用具有自吸性能的泵，如自吸式离心泵、自吸式旋涡泵、气动（电动）隔膜泵。

一、 喷嘴选型根据要求查雾的池内样本，选10个除磷喷嘴3/8 TDSS 40027kv-lcv(15°R)。

参数：喷角区分40°，额定压力5MPa ，喷量27.7L/min ，喷嘴右倾15°。

二、水泵选型计算1、水泵必须的排水能力 Q B =2016.2242024max ⨯=Q = 19.44 m 3/h 其中，系统需要最大流量16.2）601027.7（10-3max =⨯⨯⨯=Q m 3/h2、水泵扬程估算 H=K （H P +H X ）= 1.3 ⨯（178+2）=234 m其中：H P ：排水高度，160+18=178m ；（16mPa ，扬程取160m ）H X ：吸水高度，2m ；K ：管路损失系数，竖井K=1.1—1.5，斜井∂＜20°时K=1.3～1.35，∂=20°～30°时6K=1.25～1.3，∂＞30°时K=1.2～1.25，这里取1.3。

查南方泵业样本，故选轻型立式多级离心泵CDL42-120-2，扬程238m ，流量42m 3/h ，功率45kW ，转速2900r/min 。

“吸程”也叫“最大自吸高度”(也可以理解为“自吸的程度”)。

即微型泵在不加引水的情况下，能自动将水吸上来的最大高度(泵抽水口距离待抽液面的垂直距离)。

一般水源低于等于泵的摆放位置时，就需要泵有自吸能力。

例如户外旅游时，需要抽取河中的水，最好用带自吸能力的微型水泵（不可能人跑到河里先往进水管加点引水吧）。

又或者抽的液体有腐蚀、不方便加引水等等场合。

例如：有种水泵，型号叫某某BSP系列，体积并不大，但标称的吸程可以到4米，确实可以不加引水到4米，算微型水泵里比较高的。

微型水泵里，不是所有的泵都有自吸能力(“吸程”)的。

有些离心式的水泵就没有自吸能力，第一次使用必须加引水才行。

有的微型水泵虽然也有自吸能力，但标的“吸程”往往与“进水管里全部是空气”下，能抽起水的垂直高度有差距，甚至可能只有一半不到。

所以水泵选型时，吸程是个比较重要的参数。

水泵的扬程是指水泵能把水扬高的能力。

通常扬程用英文字母H表示，常用单位为米。

通俗的讲扬程就是能把水泵到多高，从水面到泵体为吸程，从泵体至抽水高度为扬程，吸程和扬程之和为总扬程，如果吸程不够扬程再高也是无法泵上水耒.潜水泵除外根据液体压强公式p=ρgh，估算大气压可压起的水柱高为h=p/ρg=10m。

各类泵的扬程计算是通过流体力学中的伯努方程式来计算的，公式可在流体力学书中查到。

一般来说可用简单的方法计算，扬程等于该泵的功率乘102倍的效率再除以流量和该液体的密度计算步骤如下：1、计算管道的比阻S，如果是旧铸铁管或旧钢管，可用舍维列夫公式计算管道比阻s=0.001736/d^5.3 其它管用s=10.3n^2/d^5.33,n为管道壁糙率；2、计算管道两端的水头差，即管道的沿程水头损失hf=sLQ^23、计算泵的扬程：H=hf+kh=sLQ^2+kh式中： Q——喷射流量，以m^3/s为单位；d——管道径；h——喷射高度，以m计； hf ——管道的沿程水头损失，以m为单位；L——管道起端至末端的长度，以 m为单位；k——大于1的系数，可取k=1.1（射流在空中因有空气阻力）。

10.4.7 冷却水水泵的选型计算（1）压缩机冷却水系统的设计冷却水的流量 ，按下式10-20进行计算：()0123.6=-w w kQ G c t t（10-20）式中：Q 0——制冷机冷负荷，kW ；k ——制冷机制冷时耗功的热量系数：本设计取1.2； C ——水的比热容，J/kg •℃；t w1 、t w2——冷却塔的进、出水温度，℃。

由于压缩机选型中已经确定冷却水流量范围，本设计取最大值进行计算。

考虑到给水泵附加10%的水量余量，冷却水系统总的流量为：1.1222=244.2m3/h =⨯G参照冷却水供回水系统水力计算表计算可知，最不利环路为：1-6-7-8-9-10-11-22-23-24-25-26-29-30~1’-2’-3’-4’-5’-6’-7’-8’-19’-20’-21’-22’-23’-24’-25’，总阻力为：82kPa（2）水泵的扬程计算冷却水泵的压力（扬程）可按下式10-21进行计算：1.1()=++f d m H h h h （10-21）式中：h f ——冷却水系统管路沿程阻力和局部阻力损失，mH20；h m ——压缩机组油冷却器水阻力，mH20； h d ——冷却塔塔程。

代入数据，由式10-21计算可得冷却水泵的压力为：()21.1()=1.18.2+10+5.4=25.96f d m H h h h mH O =++⨯根据计算参数，选取本设计的冷却水水泵，冷却水水泵型号及参数如下表10-23所示：表10-23 冷却水水泵选型型号及参数表型号 流量 m ³/h 扬程 m 转速 rpn 配电机 kw 泵效率 (%) 汽蚀余量m 重量 kg 台数 KTB150-125-315A18728148022792.55653进行水泵的配管布置时，应注意以下几点：1）安装软性接管：为了降低和减弱水泵的噪声和振动的传递，在连接水泵的吸入管和压出管上安装软性接管。

2）出口装止回阀：目的是为了防止突然断电时水逆流而时水泵受损；3）水泵的吸入管和压出管上应分别设进口阀和出口阀；目的是便于水泵不运行能不排空系统内的存水而进行检修；4）水泵的出水管上应装有温度计和压力表，以利检测。
