1.硫酸作为强腐蚀介质之一,硫酸是用途非常广泛的重要工业原料。不同浓度和温度的硫酸对材料的腐蚀差别较大,对于浓度在80%以上、温度小于80℃的浓硫酸,碳钢和铸铁有较好的耐蚀性,但它不适合高速流动的硫酸,不适用作泵阀的材料;普通不锈钢如304(0Cr18Ni9)、316(0Cr18Ni12Mo2Ti)对硫酸介质也用途有限。因此输送硫酸的泵阀通常采用高硅铸铁(铸造及加工难度大)、高合金不锈钢(20号合金)制造,但其加工难度大和价格昂贵,因此不被人们看好。氟塑料合金具有很好好的耐硫酸性能,它是中国科学院上海有机化学研究所的专利材料,我公司于1985年引进的专利技术,最早用其开发并生产耐腐蚀化工泵,经中科院实验证明,目前尚未有哪种化学介质与其能产生反应,因此采用衬氟泵(F46)是一种更为经济的选择。公司适用产品有:IHF衬氟泵、FSB强耐腐蚀离心泵、IMD氟塑料磁力泵等。

2.盐酸决大多数金属材料都不耐盐酸腐蚀(包括各种不锈钢材料),含钼高硅铁也仅可用于50℃、30%以下盐酸。和金属材料相反,绝大多数非金属材料对盐酸都有良好的耐腐蚀性,所以内衬橡胶泵和塑料泵(如工程塑料、氟塑料等)是输送盐酸的最好选择。公司适用产品有:CQB型氟塑料无泄漏耐酸泵、CQF工程塑料磁力泵(或氟塑料磁力泵)等。

4.醋酸它是有机酸中腐蚀性最强的物质之一,普通钢铁在一切浓度和温度的醋酸中都会严重腐蚀,不锈钢是优良的耐醋酸材料,含钼的316不锈钢还能适用于高温和稀醋酸蒸汽。对于高温高浓醋酸或含有其它腐蚀介质等苛刻要求时,可选用高合金不锈钢或氟塑料泵。如CQB高温磁力泵、CQ不锈钢磁力泵

7.盐水(海水)普通钢铁在氯化钠溶液和海水、咸水中腐蚀率不太高,一般须采用涂料保护;各类不锈钢也有很低的均匀腐蚀率,但可能因氯离子而引起局部性腐蚀,通常采用316不锈钢较好。公司各类化工泵都有316材料配置,如IH化工离心泵

介质的粘度对泵的性能影响是很大的,当粘度增加时,泵的扬程曲线下降,最佳工况的扬程和流量均随之下降,而功率则随之上升,因而效率降低。一般样本上的参数均为输送清水时的性能,当输送粘性介质时应进行换算(不同粘度的修正系数可查阅相关换算图表)。对于粘度较高的浆类、膏类及粘稠液的输送,建议选用砂浆泵皇冠即时比分,我公司的UHB-ZK耐腐耐磨砂浆泵即可适用于带粘度或带颗粒的介质。
