The chain is easy to rust, wear and corrosion when there is corrosive medium and water leakage. The V-belt drive will slip due to reduced friction coefficient. However, the synchronous belt drive is mesh drive, does not slip, and water plays a lubricating role on the rubber, but reduces the friction loss of the synchronous belt.
