In fact, once a plate heat exchanger unit is installed and can operate correctly, its subsequent operation.Many details also need to be considered, partly to ensure that the complete heat exchange unit can maintain normal operation for a long time.On the other hand, it can also reduce the failure rate of heating heat exchange equipment and extend the service life of the equipment.So, what details should be paid attention to during the operation of a plate heat exchanger unit?
Preparations before operation: Before operating the heat exchanger unit,First, we need to check the system connected to the heating heat exchanger unit:The heat source system, heating system, outdoor pipe network, and user terminals have been purged, flushed, and pressure tested.And it passed the acceptance test.Check if the secondary system is filled with softened water and if the steam supply is adequate.Ensure all valves are closed before starting.
Start-up preparation:
First, open all the valves on the secondary side circulating water pump and the condensate pipeline of the heat source side.The circulating water pump outlet valve is slightly open. Preparing to start the circulating water pump.And check whether the pump's starting current exceeds the rated value.
Monitoring and adjustments during operation:
Regularly check the operation of the integrated heat exchanger unit, including whether the readings of key components such as pressure gauges, thermometers, and water pumps are normal.Pay attention to whether there are any leaks, drips, or other disturbances in the system, and whether the heat exchanger unit and system are blocked.Slowly open the steam-side steam supply valve, and adjust the steam-side valve and secondary-side valve as needed.Perform various performance adjustments. Record parameters at each point regularly to ensure stable system operation.
Operation and emergency handling:
When operating intelligent heat exchange units, strictly follow the operating procedures.When performing maintenance, be sure to turn off the power to the equipment to avoid the risk of electric shock.If any abnormalities are found in the operation of the heat exchange equipment, such as excessively high temperature or leakage, the system should be stopped immediately for inspection and troubleshooting.Operating the equipment without water is strictly prohibited to avoid damage.
The above are some key points to note when operating plate heat exchanger units.This covers multiple aspects, including pre-operation preparation, monitoring and adjustment during operation, operation and emergency handling.By strictly adhering to operating procedures and performing regular maintenance, the stable operation of the unit can be ensured.
