Masterflex 泵管使用寿命要点

概要

NORPRENE® 管和 PHARMED® 管在各种应用场合下都具有最长的使用寿命。实际应用结果表明，当转速为50转/分钟时，某些尺寸的MASTERFLEX L/S® 泵管使用寿命可超过5000小时。

高性能精密型泵管比常规精密型泵管使用寿命提高20%至30%。

NORPRENE/PHARMED泵管在压力应用场合下使用寿命最长。

过氧处理硅胶泵管将使用寿命延长40%。铂金硅胶泵管具有较好的化学相容性。新近推出的耐久型铂金硅胶泵管比一般铂金硅胶泵管寿命延长5倍之多。

选择泵管时须注意:

先取一段样品在您的使用场合中试用。

欲监控泵管使用寿命，须在工作周期结束后，检查泵管是否出现疲劳现象（微孔渗漏、磨蚀等等）。

制定一份维护及更换时间表，以避免泵管失效

测试参数:

本公司的泵管使用寿命图表描述了在21摄氏度（70华氏度）温度及0巴（0磅/平方英寸）压力下以不同电机转速连续泵水使泵管的使用寿命（以小时计）。此数据是对MASTERFLEX 蠕动泵的多年测试结果。MASTERFLEX泵管寿命的确定是基于泵管失效时间，或泵送量减少到50%的时间，两者取其先。
