不锈钢化工离心泵『13775024666常州市武研热油泵有限公司』不锈钢化工离心泵根据介质特性进行机械密封选型：腐蚀性较弱的介质，通常选用内置式机械密封，它的端面受力状态和介质泄漏方向都比外置式合理。对于强腐蚀性介质，由于弹簧选材较困难，可选用外置式或聚四氟乙烯波纹管式机械密封，但一般只适用p≤0.2～0.3MPa的范围内。Stainless steel chemical centrifugal pump according to the characteristics of the medium mechanical seal selection: corrosive weak medium, usually choose a built-in mechanical seal, it is the end of the force state and media leakage direction are more reasonable than external. For strong corrosive medium, due to spring material is difficult, selection of external or polytetrafluoroethylene corrugated tube mechanical seal, but generally only applicable P is less than or equal to 0.2 ~ 0.3MPa, the range.
