Plate heat exchanger is a kind of high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, wide application and long service life. Generally, the cause of misalignment of the plate heat exchanger is nothing more than multi-pass combination and long-term use. At the same time, the large change in the flow rate and pressure of the medium makes the plate heat exchanger unable to withstand the pressure, which will cause the plate to deform.
(1) We need to understand the specific cause of the misalignment of the plate heat exchanger and then solve it. The damaged sheet and the leaked sheet can be pulled out in pairs. If the number of plates is not too large, the number of reduced runners is not large. After the heat exchanger is reassembled and continued to be used, it will not have a great impact on production.This means that the equipment cannot be changed on site, and the equipment cannot be stopped. If conditions permit, replace and maintain it.
(2) The gasket of the plate heat exchanger slides away from the gasket groove. The deformed plate and the gasket sliding away from the gasket groove should be replaced in time. After the plates are misaligned, sometimes leakage occurs quickly. Although some leaks do not occur immediately, they are a hidden danger of leakage, so they must be handled in a timely manner. The equipment needs to be maintained and maintained during operation.
