The plate heat exchanger is a kind of high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape.When the plate heat exchanger is put into use for the first time, in order to avoid the instantaneous pressure fluctuations that cause the plate heat exchanger to leak.Be sure to open the hot and cold medium water inlet valve at the same time. After exhausting the gas in the heat exchanger, slowly increase the pressure before fully opening the inlet valve, and then slowly open the hot and cold medium water outlet valve at the same time.Do not blindly switch the pressure of the medium caused by the inlet and outlet water valves to avoid leakage of the stainless steel plate heat exchanger.
Stainless steel plate heat exchangers need to be repaired and cleaned. Generally, a coarse filter is installed on the hot and cold inlet pipelines to prevent 3-5mm particles from blocking the plate channel. When the pressure difference between the front and back of the filter is large, the filter can be disassembled for cleaning. If the filter is cleaned too often, the stainless steel plate heat exchanger will fail due to blocked plate passages.
