离心式热油泵┏ 常州市高温导热油泵有限公司┓在从头拼装聚四氟乙烯O形圈轴封时,假如忘了装销钉套,就会发作碳石墨环开裂事端。缘由是聚四氟乙烯O形圈的冲突因数低,会随之旋转,当靠销钉槽一侧的碳石墨一旦与销钉俄然触摸时,碳石墨环就会开裂。离心式热油泵橡胶0形圈用于高黏度轴封时也会发作这种状况,在销钉槽处的碳石墨环有开裂或打断一块的表象。销钉槽和销钉使碳石墨环裂开而不能恢复。配以聚四氟乙烯制造的销钉套,它可在离心式热油泵密封箱压盖上起缓冲效果,安装时应使套筒高出销钉。此外,因商品精度高,对碳石墨环旋转时的这有些密封区,还需求在密封箱周围设夹套给予预热或用带预热室的压盖n the re assembly of PTFE O ring seal, if forgot to load the dowel sleeve, carbon graphite ring fracture accidents will happen.
