Plate-type heat exchanger unit is a very popular heat exchanger unit, but in order to reduce the failure rate of the plate heat exchanger unit and extend the service life, many details need to be paid attention to in the daily operation and maintenance process.
Before starting the plate heat exchanger unit, it is necessary to check whether all parts of the plate heat exchanger unit are complete, whether the connecting pipes are correct, and whether the valves and power supply are in the closed state. Open the inlet valve of the water pump, open the exhaust valve to fill the entire pump cavity with liquid, and then close the exhaust valve. Turn the water pump by hand to allow the lubricating liquid to enter the mechanical seal end face. Test the motor to determine whether the rotation is correct.
For the sequence of starting and stopping the plate heat exchanger, it is also necessary to be correct. The correct sequence for starting the plate heat exchanger is to start the circulating pump, then the hot water valve. The sequence for stopping is to close the steam valve first, and then the circulating pump and the circulating pump.
When maintaining and overhauling the plate-type heat exchanger, it is necessary to regularly clean and flush the interior of the pipeline, regularly replace the sealing gaskets and filters, regularly check the connection of the pipeline, check the seals and welds, check the supports and connecting parts, etc.
Due to limited time, I will talk about the key points of operation and maintenance of the plate-type heat exchanger unit here. I hope the above information can provide you with some help. In addition, it should be noted that when actually operating and applying the plate-type heat exchanger unit, it is necessary to combine the operation manual and maintenance guide of the specific unit to ensure the stable operation of the unit. At the same time, regular maintenance and care can extend the service life of the unit and improve its work efficiency.
