Filter cleaning of plate heat exchangers

“In order to reduce” stainless steel plate heat exchanger inspection and maintenance cleaning times, generally in the hot and cold media with a filter on the inlet line to prevent 3-5mm particles of debris blocking the plate channel. When the pressure difference between the front and rear of the filter is large, you can disassemble the filter cleaning. Too frequent cleaning of the filter will also cause the plate heat exchanger due to plate blockage and failure of the channel. Plate heat exchanger in the initial commissioning, in order to avoid instantaneous pressure fluctuations caused by plate heat exchanger leakage, shall be slightly open at the same time hot and cold media into the water valve, exhaust the gas in the heat exchanger after a slow increase in pressure until the full opening of the import valve, and then slowly and slightly open the hot and cold media out of the water valve. Blindly switch in and out of the water valve or other reasons caused by fluctuations in media pressure, are likely to cause plate heat exchanger leakage.
