Seal (mechanical)

A seal (mechanical) is like a tiny superhero who keeps water or other liquids from getting into places they shouldn't. Imagine that you want to stop water from going from one place to another, but there's a gap where the water can sneak through. A seal is a special device that fits right into that gap and stops the water from getting through.

Seals are made up of several parts. The first part is a stationary piece that stays in place, so it doesn't move. The second part is a piece that spins around, like a wheel. The spinning part has a hole in it, and the stationary part goes right into that hole. There's a soft piece of material, like rubber or plastic, that sits between the stationary and spinning parts. This soft piece helps to make a tight seal that keeps water from getting through.

When the spinning part moves, it pushes against the stationary part, which helps to make the seal even tighter. Sometimes, seals have special features that make them work even better. For example, some seals have small grooves that hold a tiny bit of lubrication, like oil, which helps the seal move smoothly and last longer.

Overall, a seal (mechanical) is a small but powerful device that helps to keep liquids from escaping where they're not supposed to go. It's like a little warrior who always has your back, making sure everything stays in place and works smoothly.
