What are the common problems and solutions for API682?

API 682 is an American Petroleum Institute (API) standard used for mechanical seals and seal expansion systems. In a wide range of applications, problems with API 682 mechanical seals are also common. Below are some common problems and their solutions.

Problem 1: Leakage

Leakage is one of the common issues in the use of API 682. Leakage may cause significant safety hazards and damage to the machine, so it must be resolved as soon as possible. Here are several reasons for leakage:

a. Improper installation: Failure to follow the guidelines and requirements of API 682 during installation, or improper installation of mechanical seals and seal expansion systems on equipment.

b. Sealing surface wear: Sealing surface wear caused leakage. Grinding should be carried out when the sealing components have worn out until the end of their lifespan.

c. Sealing component failure: Failure of sealing components, springs, and other components may also lead to leakage. During the installation process, it should be ensured that all components are in normal condition and not damaged

Treatment: Reinstall the equipment, install it correctly according to API682 standard, and finally grind the parts that need to be ground flat.

Problem 2: The hardness of the sealing surface does not match

Mismatched hardness of the sealing surface can lead to wear and collapse of the insulation material. This may reduce the lifespan of sealing surfaces and insulation materials and lead to leakage.

Solution: The hardness of the sealing surface must be matched to ensure that all implementation measures are within the range of API 682. It is recommended to use reliable hardness comparison instruments.

Question 3: Reduce density

The decrease in tightness is caused by wear or mismatch of the sealing surface. It causes the equipment to overheat, which may lead to equipment failure or other safety issues.

Solution: The wear of the sealing surface needs to be checked early to ensure that the worn area is treated and re ground flat

Question 4: Splashing or evaporating lubricating oil

The volatile and volatile properties of different lubricants may vary, leading to the volatile and volatile behavior of lubricants in mechanical seals and seal expansion systems. This may lead to significant leaks and safety hazards.

Solution: Use the standard API 682 sealing solution and follow the lubricant treatment measures.

Question 5: Recirculation stagnation

The stagnation of the re circulation may be caused by issues such as bubbles, sun handles, or sediment in the sealing components. Recirculation stagnation in sealed expansion systems may lead to lubricant contamination and jeopardize the normal operation of mechanical equipment.

Treatment: Take appropriate measures to ensure that the installation and operation of API 682 series devices are within the scope of the guidelines. For equipment involving recycling, it is recommended to establish maintenance standards and procedures.
