Sample interview questions: Can you explain your knowledge of different types of strainers and filters used in hydronic systems and their maintenance requirements?
Sample answer:
Types of Strainers and Filters in Hydronic Systems:
-
Y-Strainers: Used to remove large particles from fluid flow. They have a Y-shaped body with a removable basket or screen that traps debris.
-
Basket Strainers: Consist of a cylindrical housing containing a perforated basket. They collect larger particles than Y-strainers.
-
Inline Strainers: Compact devices that fit directly into piping. They have a mesh or screen to remove smaller particles.
-
Automatic Self-Cleaning Strainers: Feature a rotating mechanism that continuously cleans the strainer screen, preventing debris buildup.
-
Magnetic Filters: Use strong magnets to trap magnetic particles, such as magnetite, from the hydronic system.
-
Dirt Separators: Remove suspended solids and dirt from fluid flow. They use centrifugal force or gravity to separate solids from the fluid.
