Before starting the Shandong plate heat exchanger, first check if the pipeline of the plate heat exchanger is unidirectional. This is to prevent leakage. Check the inside of the Shandong plate heat exchanger for impurities or dirt, and clean it in time to prevent blockage. Open the outlet valve and close the inlet valve. You also need to check whether the inside of the heat exchanger and all accessories are corroded, rusted, and damaged. Or, during use, you need to check the overall equipment usage and sealing gaskets first. If a malfunction occurs during use, stop the machine immediately, record it, and maintain the equipment. Of course, it is also necessary to ensure that there are no impurities in the medium and control the concentration. High average pressure during the use of the Shandong plate heat exchanger means that penetration has occurred inside the equipment. It should also be noted that the pressure gauge and various accessories should be carefully observed. After discovering the problem, the machine can be stopped for maintenance according to the specific situation. Due to the relatively large size of most equipment, the possibility of problems is low, and the instrument will automatically stop.

After the process is completed, the valves of the Shandong plate heat exchanger should be closed slowly. Do not directly cut off the power to avoid damaging the equipment and shortening its service life. After the equipment is used, turn off the pump, disconnect the power, and empty all the media in the equipment. The medium remaining in the device for a long time will undergo a chemical reaction. If the pipeline and equipment have an air reaction, the outlet valve needs to be opened, and the equipment needs to be powered off for inspection and repair. Or, when the Shandong plate heat exchanger is running, in order to prevent overpressure on the other side of the heat exchanger, the inlet valves of the hot and cold media should be opened simultaneously, or a low-pressure test liquid should be slowly injected first, and then a high-pressure test liquid. The pressure fluid should be injected slowly. According to the readings of the thermometers at the inlet and outlet of the heat exchanger, the flow rate of the hot and cold liquid is controlled by the valve to achieve the required process parameters and stable operation. It should also be noted that the pipeline needs to have a vent valve. After the Shandong plate heat exchanger is running, the air in the device needs to be removed to prevent air from remaining in the device, which will reduce the heat transfer effect.

In the above article, we have told you about the precautions for using the Shandong plate heat exchanger. If you don't understand, take a look. That's all about this knowledge point, and I hope it can help you. As our factory's main product, we thank our new and old customers for their strong support.
