​Plate heat exchangers have been widely used in central heating, food, machinery, metallurgy, the petrochemical industry, and ships, and have become the leading heat exchange equipment in urban central heating projects. In order to ensure the normal operation of the plate heat exchanger and prolong the service life of key components, it is especially important to understand the failures of the plate heat exchanger, their causes, and treatment methods. The following is a description of how to deal with the heat exchanger when the pressure drop is too large.

Plate heat exchangers were first put into commercial production in the 1930s and are now being used more and more widely in water supply, heating, and air conditioning projects in industrial and civil buildings. The correct selection of plate heat exchangers can ensure the smooth implementation and use of the project. Here we introduce how to select the heat exchanger.

With increasing use, the heat exchanger's heat transfer efficiency will inevitably be affected, thus affecting normal operation. There are many reasons for the low heat transfer efficiency of plate heat exchangers. Because we all know that the plate heat exchanger heat transfer efficiency is very high, and this is one of the reasons why people often choose it. Today we will discuss this issue.

Even a plate heat exchanger can have problems during the course of a year and require maintenance, especially its seals, to see if it has loosened.

Heat exchangers are devices used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements and are an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. Its operation process can be divided into three main categories: inter-wall, hybrid, and heat storage. According to its surface compactness can be divided into two categories: compact and non-compact. Next, let's learn about the history of heat exchanger development.

The heat exchanger is a process equipment that transfers the heat between different temperature media by heat conduction from high-temperature objects to low-temperature objects when the objects reach the required temperature for production. At present, heat exchangers are not only used in large chemical raw material manufacturers but also have entered the daily use of thousands of households. Below we introduce two common heat exchanger failures.

The plate heat exchanger is a new type of high-efficiency heat exchanger made of metal plates stacked with certain corrugated shapes. The structure includes gaskets, compression plates, and frames, the plates are sealed and guided by sealing gaskets, separating the cold and hot two fluid channels. Different media flow through the respective channels and exchange heat with the separated plates to achieve the required temperature. Next, we will introduce the advantages of the plate heat exchanger.

​In actual use, fouling will gradually increase on the circulating water side of the heat exchanger, so the heat exchanger should be treated for fouling after a period of use. The formation of fouling has a lot to do with water quality. Water quality varies greatly from place to place, welded plate heat exchanger applications are different in the water quality requirements are not the same, so it is difficult to determine the minimum requirements of water quality.

Heat exchangers are widely used in various fields of industry and agriculture, and heat transfer equipment can be found everywhere in daily life, and is one of the indispensable process equipment.

Heat exchangers, as common chemical equipment, also have many problems in the process of use. Take the shell and tube heat exchanger as an example, the leakage of the tube itself is a very serious problem. In the following, we will talk about the reasons why leaks occur and hopefully help with solutions later on.
