Which component helps prevent foreign materials from contaminating the turret nozzles?

The selection of caps or other suitable devices is key to preventing foreign materials from contaminating the turret nozzles. These caps act as a protective barrier, safeguarding the nozzles from dust, debris, and other contaminants that may compromise their functionality. By keeping the nozzles covered when not in use, these protective measures ensure that the system remains operational and reliable when activated.

Other components mentioned, such as suction filters, serve a different purpose, which is to remove impurities from the extinguishing agent before it is discharged. Anti-vibration mounts are intended to reduce movement and vibrations that may affect system reliability but do not directly prevent contamination. Pressure gauges provide critical information about the system’s operational pressure but do not play a role in protecting the nozzles from foreign materials. Thus, using caps or suitable devices is the most effective way to maintain the integrity and performance of turret nozzles in dry chemical extinguishing systems.
