In the daily operation of plate heat exchangers, to prevent damage to the heat exchanger, under what circumstances should their use be avoided? This article briefly introduces these situations.
1 In 250 a usage temperature within the range of ℃ is not suitable for plate heat exchangers. The design temperature of the heat exchanger mainly depends on the temperature that its gasket can withstand. Based on rubber-type elastic gaskets, the maximum usage temperature is less than 200 ℃. Using a tightened asbestos fiber gasket, the high temperature can reach 250 ~ 260 ℃.
2 Fluids that are prone to clogging flow channels are not suitable for heat exchange. Because the gap between the plates of the heat exchanger is small, generally 3 to 5 mm, so if there are relatively large solid particles or other fibrous impurities in the heat transfer fluid, it will easily cause flow channel blockage problems.
3 In 2.5MPa It is not suitable to use a plate heat exchanger under standard pressure. The heat exchanger is sealed by a gasket. The perimeter of the seal is long, and the support condition of the two seals at the corner holes is poor, and the gasket cannot get sufficient clamping force, so the maximum operating pressure of the plate heat exchanger is only 2.5MPa ; when the single plate area is above 1m2 the standard pressure is often lower than 2.5MPa。
4 In daily use, plate heat exchangers need to be regularly cleaned and maintained to ensure long-term use.
Shandong Youkun Energy Equipment Co., Ltd. is a heat exchanger unit enterprise integrating scientific research, production, manufacturing, and installation services. With more than ten years of experience in producing heat exchangers and plate heat exchanger equipment, it has rich technical experience and provides professional pre-sales and after-sales services to new and old customers.
