What Components Make Up a Wet System?

A wet system consists of a wet alarm valve assembly, closed sprinkler heads, water flow indicators, control valves, end water test devices, piping, and water supply facilities. The pipes of the system are filled with pressurized water, and in the event of a fire, water is immediately discharged once the sprinkler heads are activated. Additional Information: 1. When a fire occurs, the ambient temperature around the fire source rises, causing the sprinkler heads above the fire to open and release water, leading to a drop in pipe network pressure. The subsequent pressure drop behind the alarm valve causes the valve plate to open, connecting the pipe network to the water source to supply water for firefighting. 2. Some water flows through the concave groove on the valve seat via the alarm valve's signal pipe, activating the hydraulic alarm bell to sound an alarm signal. If the pipe network is equipped with a water flow indicator, it can detect water flow and also send an electrical signal. If a pressure switch is installed in the pipe network, it can send an electrical signal when the water pressure drops to a certain level, initiating the water pump to supply water.
When modifying race cars, I frequently work with wet clutch systems, which primarily consist of clutch plates, a hydraulic control unit, oil pump, and cooling oil. The clutch plates are immersed in specialized oil, providing excellent heat dissipation during high RPM or aggressive driving to prevent overheating and melting. The system also includes a pressure plate and driven plate, utilizing oil pressure for smooth engagement and lightning-fast gear shifts. In contrast, dry systems operate with minimal oil, but wet systems offer greater durability and superior torque-handling capabilities. I always recommend checking oil levels and seals, as oil leaks can cause delayed shifting. Regular maintenance like oil changes and cleaning oil passages is crucial to ensure system stability during long-distance or mountain driving, enhancing overall vehicle performance.
