In order to extend the service life of brazed plate heat exchangers, in addition to mastering the correct installation method, it is also very important to learn how to use and maintain equipment correctly. Next, Shanghai Yuewei editor will share with you the installation and maintenance methods of brazed plate heat exchangers, in order to provide reference for users in need.
Installation and maintenance methods for brazed plate heat exchangers: Plate heat exchangers are divided into two installation methods based on the presence or absence of saddle brackets. For plate heat exchangers without saddle brackets, the heat exchanger should be installed on a brick saddle foundation. The installed plate heat exchanger does not need to be fixed to the foundation at this time, and the entire plate heat exchanger can move freely with the expansion change. The second method is for plate exchanges with saddle bearings. The concrete should be laid flat on the foundation first, and after it is completely dry, the saddle bearings should be completely fixed to the ground concrete with anchor bolts.
During the installation of brazed plate heat exchangers, we should leave sufficient space at both ends of the heat exchanger for maintenance and cleaning. The heat exchanger shall not operate beyond the conditions specified on the nameplate. The temperature and pressure of the medium in the heat exchanger shall be checked and analyzed to prevent abnormal operation of the heat exchanger. The heat transfer effect of brazed plate heat exchangers is closely related to scale, and the more scale there is, the less ideal the heat transfer effect. Therefore, it is necessary to clean the scale on the heat exchanger in a timely manner. To prevent excessive scaling from affecting the heat exchange efficiency.
Brazed plate heat exchanger is an efficient and practical heat exchange equipment that has been widely used in many industries. In order to improve its work efficiency and extend its service life, we need to pay attention to some issues when using this equipment in daily life. In addition, we also need to regularly carry out relevant inspections and maintenance work. Below, the plate heat exchanger manufacturer Shanghai Yuewei will explain the key points for the use and maintenance of brazed plate heat exchangers to everyone.

Although brazed plate heat exchangers are widely used and can handle over 200 types of fluids, there are specific usage conditions for each type of plate heat exchanger. Once the brazed plate heat exchanger is selected, it cannot be used casually, otherwise it will cause serious consequences. Plate heat exchangers have certain limitations on operating pressure and temperature. If they exceed this range, it will inevitably cause consequences such as leakage, corrosion, and even explosion.
Brazed plate heat exchangers belong to pressure vessels and must be regularly inspected for corrosion. If any corrosion is found, it must be repaired; When the corrosion is severe and cannot be repaired, new parts must be replaced. Don't get the order wrong when disassembling and assembling the panels. In addition, plate heat exchangers should be cleaned regularly.
Maintenance work is an indispensable measure to maintain the performance of brazed plate heat exchangers and extend their service life. Therefore, users must not ignore this work. In addition, the issues that need to be noted during the use of brazed plate heat exchangers have also been briefly introduced in the previous text,

The company has a professional foreign trade team and has trade cooperation with various regions. Some global partners conducted on-site inspections of the production plants and were very satisfied with the inspection results and established long-term strategic cooperative relationships with our company.
Comparing to other other types of heat exchanger, plate heat exchangers have larger surface area. They are composed of a number of thin metal plates compressed together. Gasket is attached to the heat transfer plate with forms flow channel and acts seal up the fluid. Different materials have different channels and in their respective flow path alternately. They won't leak to the outside. The number of the heat transfer plate is determined according to the amount of fluid, physical properties of fluid,the pressure drop and thermal condition. Each plate is corrugated to increase the maximum heat transfer area.
