Engineering and Maintenance Executive Interview Questions and Answers

There are mainly two types of mechanical seals used in processes: balanced seals and unbalanced seals.

• Balanced seals are designed to reduce the amount of heat generated and are commonly used in high-pressure applications.

• Unbalanced seals are simpler in design but are more prone to heat generation and are typically used in low-pressure applications.

Single mechanical seals have one seal face while double mechanical seals have two seal faces for better sealing performance.

• Single mechanical seals have one set of faces to prevent leakage, while double mechanical seals have two sets of faces for added protection.

• Double mechanical seals are more effective in preventing leakage compared to single mechanical seals.

• Single mechanical seals are simpler in design and easier to install, while double mechanical seals are more complex...read more
