Causes of perforation of plate heat exchanger

The plate heat exchanger is composed of a group of corrugated metal plates. There are four corner holes on the plate for the passage of two kinds of heat transfer liquids to guide the fluids to flow through their respective channels alternately for heat exchange. Plate heat exchanger is an important part of the refrigeration host. Some users will encounter the situation that the plate heat exchanger is broken down or the plate of the heat exchanger is perforated. Today, let's find out the reasons for this situation.

1. Quality reason: the heat exchange surface of other heat exchangers is relatively thin, about 0.5mm, and the annual corrosion degree is about 0.05mm. In addition to the daily strong acid and alkali corrosion, the corrosion and condition of the equipment can not be avoided after about eight years of use.

2. Protection reason: careful protection is necessary for a device to be more durable. For example, the sealing gasket of plate heat exchanger is a vulnerable component and a part that can age naturally under natural conditions. Its service life has an important impact on the service life of plate heat exchanger. If the sealing gasket loses elasticity and hardens, If it is not replaced or tightened in time, the heat exchanger will leak.

3. Cleaning reason: the plate heat exchanger shall be cleaned in time after long-term operation. The plate heat exchanger can be disassembled for plate cleaning. Some equipment cannot be disassembled and cannot be thoroughly cleaned. With the extension of service time, problems such as blockage and scaling will appear. Once the flow rate of the plate heat exchanger increases, the friction will increase and wear will appear, which has become one of the reasons for the plate breakdown of the plate heat exchanger.
