Description

Technical Field

[0002] In building ceramic enterprises, pressing is an essential process in production. The faster the pressing speed of the press, the higher the production line capacity will be, but the oil temperature of the press will also become higher and higher, so the oil temperature of the press needs to be cooled down during the production process. At present, plate heat exchangers are mainly used to cool down the oil temperature of the press. In order to achieve the ideal cooling effect, some even install 2 or even 3 sets in series. However, after the plate heat exchanger has been running for a long time, it will be contaminated by impurities in tap water and oil. The impurities are adsorbed on the plate heat exchanger, resulting in a decrease in heat exchange efficiency. Therefore, the plate heat exchanger needs to be cleaned regularly.
