Maintenance of Plastic Rasching Ring

- Jun 24, 2020-

Pre-production maintenance before operation: There is a temperature difference between the rainwater and the shutdown temperature, and there will be thermal expansion and contraction. Therefore, the pressure spring of the graphite heat exchanger should be pressurized before the production operation and reach the size of each pressure spring on the top of the heat exchanger. 140mm, to avoid leakage inside and outside the heat exchanger seal, to ensure the success rate of driving operations.

Planned parking maintenance: First release the calcium chloride solution in the system from the lowest point of the system, then add hot water to the system, and circulate and flush the graphite heat exchanger through the circulation pump. The operation is carried out at least twice until the heat exchanger releases clean water.
