As consumers, when purchasing plate heat exchangers, we all hope to purchase plate heat exchangers of qualified quality, so as to reduce the failure rate and maintain normal operation in the later application process. So, what details can be used to judge the quality of plate heat exchangers when purchasing them?
Equipment performance parameters, such as heat transfer efficiency, pressure drop, operating pressure and temperature, compactness, reliability, etc. Among them, heat transfer efficiency is an important index to measure the performance of heat exchangers, which represents the ratio of the heat transferred by the heat exchanger per unit time to the total heat load. The pressure drop indicates the resistance that the fluid encounters when passing through the heat exchanger, and a smaller pressure drop means lower energy consumption and higher fluid delivery efficiency. Compactness refers to the amount of heat that can be transferred by the heat exchanger per unit volume.
Equipment materials, the material of the plate-type heat exchanger directly affects its performance and service life. Stainless steel is one of the commonly used materials, because of its high quality and durability. Although titanium is more expensive, it performs better in some specific working conditions. The quality and service life of the gasket are crucial for the heat exchanger. A good gasket can prevent leakage and extend the service life of the equipment. For applications with high working pressure, a fully welded plate-type heat exchanger can be selected to avoid the leakage problem caused by the aging of the gasket.
Appearance and structure, qualified plate-type heat exchanger, the surface should be free of obvious bubbles, wrinkles, defects, impurities, etc., and there should be no damage or breakage. The nameplate should be clear and legible, without wear. A reasonable structural design can improve the heat exchange efficiency and service life of the heat exchanger.
Manufacturer's strength and after-sales service, understand the manufacturer's position in the industry and user reviews, choose a well-known and well-regarded brand. A complete after-sales service system can ensure the long-term interests of users. Understand the manufacturer's after-sales service content, response time, service scope, etc., to ensure timely support during the use of the equipment.
When purchasing a plate heat exchanger, you can easily determine whether the plate heat exchanger is of good quality by paying attention to the above points.
