To reduce the failure rate of the fully automatic heat exchange unit, extend the service life, and create more tangible benefits for users, many details should be paid attention to during operation, and daily inspection and maintenance work should also be done well. The operation details of the fully automatic heat exchange unit involve many details, and now let's explain one by one.
Preparations before starting the fully automatic heat exchange unit:
To ensure that the fully automatic heat exchanger unit can be started and operated normally, it is necessary to inspect and test the equipment before operation, such as checking whether the equipment support structure is solid, whether there are obstacles and flammable materials around, and ensuring that the operating environment is safe. Check whether the connections of each part of the equipment are tight and whether there is any looseness; whether the pipelines and valves are firmly installed. Check whether the connections of each part of the equipment are tight and whether there is any looseness; whether the pipelines and valves are firmly installed. Confirm that the power supply, water supply, heat source, etc. are normal. Connect the main power supply and ensure that all switches are in the off state. Check whether the equipment is in a normal working state and confirm whether there are any abnormal sounds or odors. Check whether the instruments such as the pressure gauge and thermometer are working normally. Carry out pressure test, cleaning and purging work according to the process to ensure that the equipment is clean and free of impurities inside.
Power-on Operation Procedure: Follow the instructions on the control panel to start the circulating pump. Check the current, noise, and vibration of the pump to ensure it runs smoothly. Slowly open the inlet valve on the primary side of the heat exchanger and adjust the opening of the outlet valve. Pay attention to the changes in system temperature and pressure to avoid excessive temperature and pressure. Determine the heating temperature according to the requirements and adjust the heating power. Set the value of the temperature control instrument, for example, if the set temperature is 100°C, the power supply will be automatically cut off or the heating power will be adjusted when the water temperature reaches the preset value. Start related equipment (such as a gas boiler, electric heater, etc.) for heating. During operation, monitor the temperature and pressure of the heat exchanger unit at any time. Check whether the readings of the pressure gauge, thermometer, and other instruments are normal. If there is any abnormality, stop the machine for inspection and handling in time.
Shut-down operation procedure: Close the primary medium inlet valve or cut off the heat source supply. After cutting off the heat source, wait for a period of time to allow the water temperature in the system to gradually decrease. Close the circulating pump and its outlet valve. Cut off the main power supply and other related equipment. After the machine has cooled, open the box lid to take out the heat exchanger components and store them properly for future use. Regularly clean and maintain the equipment, such as cleaning the internal pipeline of the heat exchanger, replacing filters, etc.
