The heat exchanger is a high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. The material of the plate heat exchanger gasket mainly includes nitrile butadiene rubber (NBR), ethylene propylene diene monomer (EPDM), high temperature nitrile butadiene rubber (HNBR), and fluoro rubber. It is an important part of the plate heat exchanger. Its quality affects the overall performance and working conditions of the plate heat exchanger. What is the reason for the gasket aging in the plate heat exchanger in use?
(1) The aging of the elastic gasket is related to excessive pressure. When the gasket loses its elasticity, the heat exchanger water will leak out.
(2) When the bolts of the plate group of the new plate heat exchanger are loosened, the bolts of the combined plate heat exchanger can be tightened again. The pressing force of the elastic gasket is increased, temporarily solving the leakage problem. The specific strength used depends on the number of heat exchanger fins in each group. It can be adjusted once or multiple times.
(3) Please pay attention to moisture-proof and moisture-proof in the normal use of the plate heat exchanger, and make timely adjustments to avoid some failures and unnecessary losses.
(4) We recommend to reserve a set of spare heat exchanger gaskets. The heat exchanger rubber gasket is sealed and stored, and it can be up to 3 years under normal temperature conditions.
