3. ZDR Series Electric and Steam Heating Water Tank Principle Description
    This series heating water tank can be combined to use with fresh water pressure tank on board, that is to use fresh water in fresh water pressure tank to replenish this tank, and then heated by electric or steam heating elements   for usage of entire vessel.
    Temperature controller:  The water temperature in tank is controlled by two WTZK-50-C pressure type temperature controllers; If the water temperature in tank is lower than 50℃, the power will be on automatically and the electric heater will begin to heat; If the water temperature in tank is higher than 65℃, the power will be off automatically and the electric heater will stop heating.
    Temperature regulating valve:  open and close it according to the set temperature control range.
    Float level Switch:  to protect the electric heater, if the liquid level in tank is lower than float level switch, the electric heater will cut off automatically.
    Pressure gauge:  to show the pressure in tank.
    Thermometer: to show the water temperature in tank.
    Safety valve:  If the pressure in tank is more than 0.42MPa, the safety valve will open to release the pressure in tank.
    Note:  Never wind the raw material belts into the inlet of safety valve when installing the safety valve.
    Electric control box:  There two kinds of hot water controlling: manual control and auto control. When the change-over switch SA2 is turned to “Manual”, the electric heater will start to heat until the water in tank reaching  65℃. Then the electric heater stops heating. When the change-over switch is turned to “Auto”, at this moment, if the water temperature in tank is lower than 50℃, the electric heater will start to heat automatically until the water in tank reaching 65℃. Then the electric heater stops heating. If the float level switch finds that there is no water in hot water tank, the electric heater controlled by electric control box will not work. For the hot water tank which has two or three groups of electric heater, the device will adopt segmentation heating method to realize due to the large power of electric heater. 1min later, another group electric heater will start to work. By that analogy, all of the electric heater will stop heating after the water in tank reaching 65℃.
4. ZDR Series Electric and Steam Heating Water Tank Operation method
(1) Adjust the temperature control range.
     Set the low temperature and high temperature of temperature regulating valve to 50℃ and 60℃ separately.
Set the low temperature controller and high temperature controller to 50℃ and 65℃ separately.
(2) Set the open pressure of safety valve
     Set the open pressure of safety valve. When the pressure in tank is over 0.42MPa, the safety valve will take off to release the pressure in tank.
(3) Normal operation
     Open the water inlet and outlet valve. Start the electric heater. When the temperature in tank is lower than 50℃, it will start automatically until the temperature reaching 65℃.
     If using the steam heater, start the temperature regulating valve. When the temperature in tank is lower than 50℃, it will open automatically until the temperature reaching 60℃. Then close.
     If using the electric heater, start the electric heater. When the temperature in tank is lower than 50℃, it will open automatically until the temperature reaching 60℃. Then close.
