What details should be paid attention to when maintaining the plate heat exchanger unit?

Plate heat exchange unit is a heat exchange equipment that uses plate heat exchanger as the core component.It has the characteristics of high heat transfer efficiency, compact structure, small footprint, high degree of intelligence, easy operation and maintenance.However, in the process of applying plate heat exchanger units, in order to reduce the failure rate and extend the service life,In addition to mastering the correct operation methods of the plate heat exchanger unit, it is also necessary to regularly maintain and service the plate heat exchanger unit.

Clean plates and pipes regularly to remove dirt and particles to prevent blockage and poor heat conduction.When washing, you should choose appropriate cleaning agents to avoid damaging the plates.Also, be careful to avoid using cleaning agents containing chloric acid (such as hydrochloric acid). You can choose a descaling pickling method such as nitric acid.The cleaning procedure usually includes steps such as cleaning agent selection, disassembly, cleaning, drying, assembly and commissioning.

Inspection and replacement:The sealing gasket is a very important component of the plate heat exchanger unit. If the sealing gasket is aged or damaged, it will easily lead to leakage and affect the performance of the unit.Therefore, the sealing gasket needs to be replaced regularly, and it is generally recommended to replace it once a year.The pipe connections in the plate heat exchanger unit are prone to loosening and leakage. At this time, it is necessary to check in time and retighten the pipe connections to ensure the normal operation of the unit.When using a plate heat exchanger unit, the filter needs to be replaced regularly to ensure the cleanliness of the medium and avoid contamination and blockage.

Maintenance precautions for plate heat exchanger units cover cleaning, inspection and replacement, corrosion prevention and inspection, casing and radiator, etc.By strictly implementing these maintenance measures, the normal operation of the plate heat exchanger can be ensured. During operation, it is necessary to pay close attention to the operating status of the equipment. Once an abnormality is found, it is necessary to stop the equipment in time for processing.
