辰龙泵业优质DA型多级泵 卧式多级泵4DA-8X9整机及配件

产 品： da型多级离心泵产品概述：da型泵系单吸多级分段式离心泵，供吸送清水及物理化学性质类似于水的液体之用。本型泵扬程在 50 至 600 米时，流量为 10 .8 米 3 时至 720 米 3 / 时，液体，Zui高温度不得超过 40 ℃，适合于矿山排水，工厂及城市给水之用。结构说明：da型泵为多级分段式，其吸入口位于进水段上成水平方向，吐出口在出水段上垂直向上，其扬程可根据使用需要而增减水泵级数，本型泵之装配良好与否性能之影响特别显著，万其是各个叶轮的出口与导翼进口之相对位置，每级叶轮的吐出口中心必须对准导翼的进口中心，其中稍有偏差即将使整个性能受到影响，效率降低，故在检修后装配时务必注意，若有偏差必须调整，从转动方向看去，水泵均为顺时针方向旋转。泵型号级数流量q扬程h(m)转数n(r/min)功率n(kw)效率η（%）必需汽蚀余量（nph）r(m)叶轮直径d(mm)泵重量（kg）m3/hl/s辅功率ps电机功率2da-8210.814.421.634562018.616.61414501.181.331.481.652.2505555502.3182140310.814.421.634563027.924.92114501.771.992.222.483505555502.3182160410.814.421.634564037.233.22814502.362.652.963.304505555502.3182180510.814.421.634565046.541.53514502.953.313.704.135.5505555502.3182200610.814.421.634566055.849.84214503.543.984.444.957.5505555502.3182220710.814.421.634567065.158.14914504.134.645.185.777.5505555502.3182240810.814.421.634568074.466.45614504.725.305.926.6011505555502.3182200910.814.421.634569083.774.76314505.315.966.667.4211505555502.31822803da-8225.232.439.679112522.61914502.823.123.4246164602.75204164325.232.439.6791137.533.928.514504.2134.685.127.56164602.75204208425.232.439.679115045.23814505.636.246.83116164602.75204252525.232.439.6791162.556.547.514507.047.88.55116164602.75204296625.232.439.679117567.85714508.459.3610.25156164602.75204342725.232.439.6791187.579.166.514509.8510.912156164602.75204386825.232.439.6791110090.476145011.2512.513.718.56164602.75204430925.232.439.67911112.5101.785.5145012.671415.418.56164602.752044744da-8236547210152034.43228.414506.487.48.2115263.5683.3232263336547210152051.64842.614509.7211.112.3155263.5683.3232321436547210152068.86456.8145012.9614.816.4225263.5683.32323795365472101520868071145016.218.520.5305263.5683.32324376365472101520103.29685.2145019.522.224.6305263.5683.32326987365472101520120.411299.4145022.725.928.7375263.5683.32325568365472101520137.6128113.6145025.929.632.8455263.5683.32326149365472101520154.8144127.8145029.233.436.9455263.5683.3232672本产品的品牌是辰龙，型号是4DA-8X9，材质是铸铁，性能是无泄露，流量是54（m3/h），叶轮数目是9，扬程是144（m），规格是4DA-8X9,4DA-8X8,4DA-8X7
