To ensure the normal operation of the plate heat exchanger is very important for the operation of the whole set of machines, we should pay attention to the routine maintenance and maintenance of the machine, the plate heat exchanger in different areas of operation is also to master the key points.
This is the plate heat exchanger manufacturer for our summary of the plate heat exchanger in the different areas of operation points.
1. Hot water heating:
Hot water heating, generally not high temperature, slow heating speed, stable operation, as long as regular discharge of non-condensable gas, can ensure normal operation.
2. Steam heating:
Steam heating requires constant exclusion of condensate, or accumulate in the plate heat exchanger, part or all of it becomes no phase change heat transfer, heat transfer rate decreases. Also need to discharge non-condensable gas in a timely manner. Because the presence of non-condensable gas makes the steam condensation of the heat giving coefficient is greatly reduced.
3. Condensation:
Condensation operations require attention to the regular discharge of non-condensable gases from the steam side, especially under reduced pressure conditions.
4. Water and air cooling:
Operation pay attention to adjust the amount of water and air according to the seasonal changes, with water cooling, but also pay attention to regular cleaning.
5. Heat-conducting oil heating:
Heat-conducting oil heating is characterized by high temperature (up to 400 ℃), viscosity, poor thermal stability, flammability, temperature adjustment difficulties, operation should be strictly controlled import and export temperature, regular inspection of the inlet and outlet and media flow channel whether scale, to do regular drainage, regular emptying, filtering or replacement of heat-conducting oil.
6. Freezing brine cooling:
Its characteristics are low temperature, corrosive, plate heat exchanger in operation should be strictly control the import and export temperature to prevent crystallization blocking the media channel, to regularly empty and drain.
7. Flue gas heating:
Flue gas is generally used to produce steam or heating, vaporizing liquids, flue gas temperature is high, and the temperature is not easy to adjust, in the operation process, to pay attention to the level of the heated material, flow and steam production, but also to do regular drainage.
With the widespread use of plate heat exchanger, plate heat exchanger operation needs to pay attention to more and more matters, after Isiop will continue to share for you to organize, you can also call directly to consult related issues.
