Working Principle of the 53B System 2026-02-05

The 53B system uses an accumulator to keep barrier fluid pressure higher, prevents leakage, alarms on major leaks, supports manual replenishment, and cools fluid via a heat exchanger or finned tube.

Plan 53A Seal Support System: Applicable Conditions & Working Principle 2026-02-04

This paper introduces the application scope of the Plan 53A system for hazardous and special process media, explains its working mechanism to prevent medium leakage to the atmosphere, and describes that seal leakage can be judged by the liquid level indicator of the liquid accumulator.

Plan 21 and Plan 23 Heat Exchanger Introduction 2025-12-01

The heat exchanger in the sealing auxiliary system is a key heat dissipation component that conforms to the API 682 standard. It is often used in conjunction with different flush plans, and its core function is to cool the sealing medium and stabilize the sealing end face. Its structure, type, and applicable scenarios are highly matched with the operating requirements of the sealing system.

Introduction of Non-Cartridge Mechanical Seal 2025-08-06

Non-cartridge mechanical seals are a traditional structural form of mechanical seals. Compared with cartridge mechanical seals, their core feature is that each component needs to be installed and debugged separately. In the sealing systems of rotating equipment such as industrial pumps, compressors, and agitators, non-cartridge mechanical seals are still widely used due to their flexible structure and low cost.

What kinds of pumps will use mechanical seals a lot? 2025-06-19

The application of mechanical seals is closely related to the working conditions of the pump (pressure, temperature, medium characteristics). Centrifugal pumps, reciprocating pumps, rotor pumps, etc. widely use mechanical seals due to the need for medium transportation, while special working condition pumps (such as high temperature, low temperature, slurry pumps) require targeted seal designs. When selecting mechanical seals, it is necessary to match the material (such as silicon carbide, fluororubber), structure (single end face, double end face) and auxiliary system (flushing, cooling) according to the type of pump and medium characteristics to ensure the sealing effect and equipment reliability.

Mechanical Seal for the Reactor 2025-05-24

The mechanical seal for the reactor is the core component of the reactor shaft sealing system. It is mainly used to prevent the medium in the reactor (such as flammable, explosive, toxic, harmful or high-purity materials) from leaking to the outside, and to prevent foreign impurities from entering the reactor to ensure the safety, sealing and stability of the reaction process.

Single Mechanical Seals and Double Mechanical seals 2025-05-17

Mechanical seals are key components used to prevent fluid leakage in rotating machinery (such as pumps and compressors). They can be divided into single mechanical seals and double mechanical seals according to their structure. The design principles, application scenarios and performance characteristics of the two are significantly different.

How to choose the right flushing plan for a specific mechanical seal? 2025-05-12

To select a flushing plan suitable for a specific mechanical seal, you need to consider a variety of factors such as medium characteristics, operating parameters, equipment type, etc.

Function of seal flushing plan in mechanical seals and seal support systems 2025-05-10

API 682 standard specifies a variety of mechanical seal flushing plans, suitable for different working conditions and requirements. The specific flushing plan should be selected based on the medium characteristics, working parameters, equipment type, cost and maintenance and other factors. The mechanical seal flushing plan is designed to effectively remove heat, flush impurities, prevent seal surface wear and scaling, and extend the service life of the mechanical seal by introducing clean fluids, controlling temperature and pressure, etc.
