Steam car wash is a sensitive device that requires constant care and maintenance for excellent performance. In order to make the most of your steam car wash machine and it will be useful for you for a long time, you must be careful in maintaining it and follow the manufacturer’s instructions. One of the things you need to be careful about is the necessary recommendations when turning off the steam car wash. Here are the most important things to do before removing the steam car wash from the circuit and turning it off:
Gradually reduce the amount of steam produced by the steam car wash machine
Sudden shutdown of the device may damage it. Gradually reduce the amount of steam generated by the appliance to a minimum. If your car wash has several burners, first reduce the number of burners and reduce the inlet air to the combustion tank, this will gradually reduce the amount of evaporation. If we close the inlet fuel first, it will turn off all the burners at once, so we have to turn off several burners gradually without reducing the fuel pressure.
Manual adjustment of controllers
The main boiler controllers, such as the steam, air and fuel pressure controllers, must be switched from automatic to manual mode. This is done for two reasons: 1- These controllers are designed to operate in the standard condition of the boiler and are not reliable in the event of a shutdown when the condition of the steam generator gradually changes. 2- Eliminate the interference of the controllers in the condition of the device
Turn off all burners
All boiler burners are turned off at this stage. When the burners are completely turned off, the drain valves that direct steam out of the appliance must be open.
Close the fuel valve
Your steam car wash machine uses any type of fuel when it is off, it is better to close the fuel inlet completely. Especially if diesel fuel is used, leaving the diesel valve may cause fuel to enter the furnace.
Evacuate the steam car wash machine
When the steam pressure is reduced, the drain valve of the device should be opened to drain if there is dirt or sludge in the container. The furnace temperature at this stage should be less than 100 degrees Fahrenheit.
According to the manufacturer’s recommendation, the operation of turning off the steam car wash may be somewhat different from the items mentioned, but obviously, if you want to use your steam car wash machine well for a long time, it will be especially important to follow the tips and items stated by the manufacturer. .
