Pressurised barrier fluid circulation in outboard seal of dual seal configuration through a seal support system. Circulation is maintained by using pumping ring in running condition and with thermosyphon effect in stand still condition.

Plan 53A是通过外部的储罐来给密封腔提供清洁流体，储罐内的流体的压力高于被密封介质的压力，然后通过泵来循环。 Plan 53A外接压力源、内置盘管冷却、并设有压力、液位等报警指示装置；储液罐是由惰性气体 (一般为氮气)加压的，隔离液的压力是由一个外部的气体调节器控制的，对隔离液压力有明确的规定，外部密封腔的压力应高于被密封介质的压力0.14~0.17MPa，如果压力太大会导致内密封流向变化，使外密封过早失效。 Plan 53C隔离液由介质通过增压罐升压后 …

Provision of cooling coil inside the reservoir or an external water or air cooler takes care of the heat removal. Uses an internal circulating device to ensure barrier liquid circulation. Barrier …

2024年8月29日 · This blog explores the evolution of mechanical seal support systems, the specifics of API 53A, its integration with double mechanical seals, and a comparison with other seal support plans, including API Plan 62. We will also discuss design and maintenance considerations, real-world examples, and future trends in mechanical seal support systems.

Pressurized external barrier liquid reservoir supplying clean fluid to the inboard and outboard seal faces. This plan is used in Arrangement 3 seals and requires the use of a pressurized barrier …

Discover API Plan 53A: a mechanical seal pot with a reservoir circulating pressurized barrier fluid between inboard and outboard seals, powered by nitrogen.

2023年7月14日 · 在API682标准 机械密封冲洗方案53A 中，采用外部气体加压隔离液储罐为隔离流体密封腔提供清洁的隔离液，利用内循环装置将隔离液从储罐输出，之后再返回到储罐。

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: Self-contained process fluid Zero emissions Applications: Hazardous fluids Toxic fluids Heat transfer fluids

API Plan 53A uses an external reservoir to provide external pressurized liquid (barrier liquid) for arrangement 3 Seals. The reservoir pressure is maintained by a gas, usually nitrogen at a pressure 2Kg/Cm2 above stuffing box pressure.

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。
