The AESSEAL ® Seal Auxiliary Systems Division has established a pioneering method of developing API Plan 53B Systems. Plan 53B systems have been viewed as an “engineering challenge” around the world, often with long lead times. The innovative modular concept permits 12 modular options to be applied to create an API 53B System for any application.

High reliability as a stand-alone system without need for a permanent nitrogen source and external pressure. Heat removal by water or air cooler. Uses an internal circulating device to ensure barrier liquid circulation. Barrier liquid enters the process medium through the inner seal faces. For services where product dilution is acceptable.

Plan 53B是通过一个气囊加压器来给密封液循环系统加压，然后通过泵来循环，同时通过空冷或水冷来带走热量。 Plan 53B的压力由内置充气的皮囊提供，采用翅片管直接散热或水冷器方式冷却隔离液；外部管道系统为加压双端面密封装置的外侧密封提供隔离液 ...

API 方案 53B 在内侧与外侧密封之间循环加压的隔离液。 增压源为气囊式蓄能器。 方案 53B 具有不允许气体吸收入隔离液中的优点，从而允许在比方案 53A 更高的压力下操作。

2024年4月15日 · An American Petroleum Institute (API) plan 53B system is a pressurized liquid barrier system connected to a dual pressurized mechanical seal that supplies the seal with clean, cooled barrier fluid at a pressure greater than that of pressure in the pump seal chamber, ensuring zero emissions of the process fluid.

2023年7月15日 · 在API682标准 机械密封 冲洗方案53B 中，由囊式蓄能器加压的隔离液系统为抑制液密封腔提供清洁的隔离液，隔离液流体采用内循环装置来进行循环。

Plan 53B requires the use of an extraneous barrier fluid system pressurized by a bladder accumulator delivering clean fluid to the seal faces. View Product. Used with Arrangement 3 …

2021年2月24日 · The main deciding factor in choosing between the two plans is the process fluid pressure that needs to be maintained. Pressures above 10.34 bar (150 psig) favor 53B. Also note that 53B can be configured so that a single system supports multiple pumps, which from an operational perspective may be ideal, even if high-pressure is not a deciding ...

API Plan 53B circulates a pressurized barrier fluid between the inboard and outboard seals. The source of pressurization is a bladder accumulator. Plan 53B has the advantage of not allowing gas absorption into the barrier fluid which may allow for operation at …

PLAN53B是通过一个气囊加压器来给密封液循环系统加压，然后通过泵来循环，同时通过空冷或水冷来带走热量。 Plan53B的压力由内置充气的皮囊提供，采用翅片管直接散热或水冷器方式冷却隔离液；外部管道系统为加压双端面密封装置的外侧密封提供隔离液，预先加了压的气囊储压器提供压力给循环系统．如图2所示。 预加压的胆式蓄压器提供压力给循环系统，流量由一内部泵送环保持。 热量通过一空气冷却或水冷却的换热器在该系统中除去，取代了方案Plan53A中储液罐。 …
