IN THE COMMERCIAL BUSINESS ELECTROMOTIVE CAR FOR A SUBWAY TUNNEL AIR QUALITATIVE IMPROVEMENT LOADING A SPRINKLER SYSTEM

摘要

PURPOSE: A spraying apparatus loaded at an electromotive vehicle is provided to cool the temperature of rails by concentratedly spraying water on the surfaces of the rails if the surrounding temperatures of the rails are higher than a pre-set temperature. CONSTITUTION: A spraying apparatus loaded at an electromotive vehicle includes a water supplying hole, a water supplying tank, a pressurizing motor, a pump, a pressure adjusting valve, a controlling panel, a distributing pipe(330), and spraying nozzles(270, 280). The pressurizing motor and the pump supply pressurized water to the spraying apparatus. The pressure adjusting valve adjusts the pressure of the pressurized water. The distributing pipe induces the pressurized water. The pressurized water is sprayed through automatic valves(250, 260), the distributing pipe, and the spraying nozzles.
