2023年7月24日 · Plan 53A、B和C是机械密封冲洗系统的不同方案。 - Plan 53A：该方案通过外设加压隔离液储罐提供清洁液体给密封腔，循环由内部输液环完成。 隔离液储罐的压力大于被密封工艺液体压力。

API 方案 53A 利用储液罐并在内侧与外侧密封之间循环加压的隔离液。 典型的增压源为植物氮。

This guide outlines the installation, operation, and maintenance of Flexaseal Plan 52 & Plan 53A Seal Support Systems for dual mechanical seals. This guide, in addition to the manuals provided by the pump manufacturer and the manufacturer of any auxiliary equipment, should be read in their entirety prior to installation.

用于双端面机械密封的辅助系统PLAN 53A 为机械密封提供隔离液，有效改善机械密封的工作环境，高效提高机械密封的可靠性以及使用寿命，提高机械密封的工况使用范围。

In Plan 53A there is a pressurized external barrier fluid reservoir supplying clean fluid to the barrier fluid seal chamber. The barrier liquid is maintained at a pressure greater than seal chamber pressure. Advantages: Applications: Note.
