With the development of the times, heat exchanger equipment is also more and more closely related to our food, clothing, housing and transportation business production, heat exchanger plate as an important part of the heat exchanger, the role can not be ignored, and the service life of the plate determines the heat exchanger's ability to work and service life of the whole machine, that is to say, the heat exchanger service life is the reason for the long service life is the plate heat exchanger plate service life is long. Then we have to understand the use of long time plate have gone through what kind of production process.
Production process of plate heat exchanger plate sheet
1. Inspection
First of all, the raw material from the plate piece of a flat sheet of material to start, raw material manufacturers are also divided into domestic and foreign, foot thick and standard; wait until the raw material comes to the plate heat exchanger manufacturer, first of all, the surface quality of the flat sheet of material as well as the material into the warehouse to check.
2. Cut the plate
Then according to the size of the target processing plate for cutting plate, cut off excess edges, which in the shearing, for the cut surface inspection, to ensure that there is no burr, curled edges and other issues. At the same time, we should also check the size of the board after cutting to ensure that the size is accurate.
3. lubrication
In the flat plate material after shearing, according to the material of the plate needs to be bagging / oiling and other operations, the purpose is to ensure that in the process of pressure plate, to ensure that the amount of thinning in line with the relevant provisions to ensure that the plate in the process of use will not occur because of excessive deformation and thus lead to leakage and other issues.
4. Pressure plate
Then the pressure plate, the quality of the pressure plate for the mold precision requirements are very high, high precision and high pressure press, the quality of the plate formed by the press is guaranteed, while the plate for the press out, but also need to carry out penetration testing to ensure that there will be no cracks that are not visible to the naked eye, thus causing quality problems. At the same time, the specific size of the pressed plate, slot depth, etc., should be checked, the plate for quality control.
5. Punching
After pressing the good need for the plate corner hole punching operation, at the same time, according to the first version, blind, special version of the different heat exchanger design requirements, punching the location of the hole is also different, some of the plate punching three holes, some of the plate punching a hole in the plate, the number of different angle holes in the plate with each other, in order to form a heat exchanger with a multi-process for a number of special conditions, not only to improve the economic efficiency, but also play a very good Heat exchange effect.
Seems very simple plate production process, in fact, the process is much more than imagined, less which step will have deviation, the regular plate heat exchanger plate manufacturers unique traceability system, to ensure that each piece of plate from the beginning of the raw material can be quality control, in the production process of control, only to be able to quality assurance.
