从五个方面去选择英格索兰隔膜泵的泵体

来源: 时间:2020-10-10 16:13:02 次数:

 (1)阀芯形状结构主要根据所选择的流量特性和不平衡力等因素考虑。


(2)耐磨损性当流体介质是含有高浓度磨损性颗粒的悬浮液时,阀芯、阀座接合面每关闭都会受到严重摩擦。因此阀门的流路要光滑,阀的内部材料要坚硬。


(3)耐腐蚀由于介质具有腐蚀性,在能满足调节功能的情况下,尽量选择结构简单阀门。


(4)介质的温度、压力当介质的温度、压力高且变化大时,应选用阀芯和阀座的材料受温度、压力变化小的阀门。


(5) 防止闪蒸和空化闪蒸和空化只产生在液体介质。在实际生产过程中,闪蒸和空化不仅影响流量系数的计算,还会形成振动和噪声,使阀门的使用寿命变短,因此在选择阀门时应防止阀门产生闪蒸和空化。
