Ships:

The steam turbine system is the power source of the ship. In this system, the function of the trap is to remove steam condensate, avoid the corrosion and impact of moisture on the system equipment, and prevent the system from clogging or even malfunctioning. Using the "self-powered" working principle of the trap, the system can automatically open and close the valve according to the water level or pressure, so as to achieve efficient and safe water removal and ensure the continuous and stable operation of the system.
