Pressure influence The detachable plate heat exchanger leaks when used within the rated working pressure. Brazed Plate Heat Transfer FHC022 Because the heat transfer components of this type of equipment are made of stainless steel sheets (thickness 0. New gasket. Time affects the equipment used or idle for several years. When the temperature changes too fast, the linear expansion coefficient of the rubber gasket does not match the elastic deformation and the seal pre-tightening force, which will reduce the sealing pre-tightening force and cause the pressure capacity of the equipment to be lower than the rated design pressure. 2, temperature influence abrupt changes in temperature can also cause seal failure.5-0.5 to 2 times when selecting the equipment; 2) Try to avoid the impact of the system during use, such as adding in the pipeline Water-proof hammer, air hammer device and strict operating procedures are formulated to prevent operator misoperation from causing pipeline impact; 3) In applications where such accidents have occurred, measures can also be taken to increase the thickness of the plate according to the situation, and its effect Obviously, but it will reduce heat transfer efficiency. The self-aging of the sealing material may affect the reliability of the seal, so it should be replaced in time by the opportunity of maintenance.8mm), its sealing rigidity is relatively poor and the sealing periphery is very long, so the impact resistance ability is far lower than other types of heat exchangers..The main reasons for the failure of the seal of the plate heat exchanger in industrial production are as follows: 1. Preventive measures: 1) In view of the structural characteristics of the plate heat exchanger, according to the operating pressure, the design pressure can be increased by 1. The instantaneous pressure peak caused by the impact is often 1 to 3 times higher than the normal working pressure, which causes the rubber gasket installed in the plate heat exchanger to shift and cause the seal to fail.
