Plate heat exchanger as beyond the traditional heat exchanger advantages are still relatively obvious, its structure is simple, easy to install, high heat transfer efficiency. Its small footprint is gradually making it the equipment of choice for heat transfer systems. The plate heat exchanger has a single component, but there are a lot of items in it that are durable, do you know which ones?
To understand this question, it is necessary to first understand, plate heat exchanger are composed of what parts, its components are:the upper guide rod, the Lower guide rod, fixed clamping plate, movable clamping plate, heat exchanger plate set, sealant gasket, clamping bolt, post, connection. One of the most loss-prone is the heat exchanger plate set and the sealant gasket.
The reason is that, heat transfer plate group and sealing gasketcomposed of media flow channel in direct contact with the medium, a long time will produce wear and tear or even corrosion, so that the performance of the plate and gasketto reduce, the need for timely maintenance and replacement.
Some people will certainly ask, in the choice of plate heat exchanger is certainly based on the specific conditions to choose the plate, gasket, yes, for each different conditions and different media can choose the plate material 304, 304L, 316, 316L stainless steel, as well as special materials such as titanium, Hastelloy, etc.; sealing gasketmaterial are mainly NBR, EPDM, and FPM, etc., their respective temperature and corrosion resistance properties of the medium are different.
Plate and seal gaskets with the combination is indeed for the actual conditions to set, but the actual plate heat exchanger in the operation process, there will be impurities, corrosive media adulteration, there may not be any problem in a short period of time, but the accumulation of years of corrosion will occur, so regular maintenance.
Can not be ruled out is that some people do not understand their own working conditions and media, haphazard with the material, plate heat exchanger will not be long out of the problem, so it is necessary to listen to the advice of the factory professional engineers.
Consumables in the plate heat exchanger parts are plates and rubber gaskets, but through regular testing, maintenance, you can make them into "wear resistance", to extend the service life.
