What is the name of the plate at the bottom of a tank that stabilizes the stream when a pump is receiving suction supply?

The term for the plate located at the bottom of a tank that plays a crucial role in stabilizing the stream when a pump is drawing in suction supply is known as the anti-vortex plate. This component is designed specifically to mitigate the formation of vortices that can occur in open liquids, especially when there are changes in flow or when the liquid level in the tank is low. By preventing these vortices, the anti-vortex plate helps maintain a consistent flow of liquid into the suction line, which is essential for the efficient operation of the pump. A stable stream ensures that the pump does not experience cavitation or air entrainment, both of which can significantly impair its performance and longevity.

In contrast, the other options do not serve this specific purpose:

• An eccentric plate relates to flow adjustment and is not primarily for stabilizing streams.

• A throttling plate is used to regulate flow but does not prevent vortex formation.

• A strainer plate is intended to filter out debris from the liquid, which does not relate to preventing vortex issues.

Thus, understanding the unique role of an anti-vortex plate is important for maintaining effective pump operation in sprinkler systems.
