计量泵阐明 计量泵也称定量泵或份额泵。计量泵是一种能够满足各种严肃的工艺流程需求,流量能够在0-100%规模内无级调理,用来运送液体(特别是侵蚀性液体)一种特别容积泵。计量泵的控制计量泵每一次的流体泵出量决议了其计量容量。 计量泵是单向容积泵,泵腔内的压力大于外界压力时计量泵才干打出液体。当外界压力高于标牌上的压力时,计量泵功课在超负荷状态。假如是电磁隔阂计量泵,其流量会下降很多,甚至打不出液体;假如是电机驱动的计量泵,电机有或许过热损坏。 FKM系列液压隔阂计量泵的特色:极具特色的液压隔阂计量泵集中帆布包女...
1)计量泵稳态精度: ±2%的额定流量。假如计量泵实测100%冲程流量是1000L/h,则稳态精度答应偏差是±2%*1000=±20 L/h。稳态精度是指加量泵和相关系统在不做任何调整与改变的条件下,在不同时间点对加量泵流量进行标定,所得到的流量偏差。 2)线性精度:±3%的额定流量,假如计量泵实测100%冲程流量是1000L/h,则线性精度答应偏差是±3%*1000=±30L/h。线性精度是指在计量泵10%~100%行程范围内,平均选取不同行程点进行流量标定,所得到的实测流量与最佳拟合值之间的偏差 3)重复精度:±...
有些用户在使用计量泵的过程中会遇到一些问题,不知道如何处理,今天爱力浦给大家总结了几点计量泵应用过程中常见问题的处理方法,希望对大家能有所帮助。 一、当运行加药系统时应注意哪些重要事项? 当运行加药系统时重点注意以下事项: A. 投加点压力 B. 冲程频率 C. 吸升高度 D. 海拔高度 E. 化学品的腐蚀性 二、当计量泵出口为大气压时,有什么办法可以提高泵的重复计量精度? 在计量泵排出阀安装阀弹簧可以改善重复计量精度,但是最有效...
