Precautions before operation of plate heat exchanger
1. A certain inspection place should be reserved around the position of the plate heat exchanger of the equipment.
2. Prevent sand, oil, welding slag and other debris from entering the plate heat exchanger, and clean the pipes connected to it before the equipment, which will block the flow channel or damage the plates. In addition to the volume of the equipment itself, there is no need to reserve space for rated inspection and equipment. The plate heat exchanger has a small footprint and light weight. The thickness of the plate used for heat exchange is 0.6-0.8mm.
3. Close the medium solenoid valve on the high pressure side first, and then close the medium solenoid valve on the low pressure side when the plate heat exchanger is shut down in sequence. Today, with exaggerated high efficiency, environmental protection and energy saving, the advantages of plate heat exchangers in the field of heat exchange have become increasingly significant. They can be used in various processes for heating, cooling and food disinfection, and they also have significant economic benefits. , In terms of low-level heat recovery.
