In the long-term radiator manufacturing experience, we have accumulated a large number of product technology experiments, from which we found that the core technology of good radiator has a very important impact on the use of product functions, efficiency, life, etc. Especially the pressure level of radiator, temperature level, heat dissipation structure, heat pipe wall thickness and other factors. It plays a decisive role in the overall performance of the radiator.

We have summarized some experience of retrofitting the high-pressure radiator in normal operation, which can be used for reference by colleagues or users.

1. Forming machine was basically heated by heat conducting oil. Due to environmental protection and other reasons, enterprises in the park need to shut down the original boiler equipment and use high-pressure steam to run. That is, the original low-pressure heat transfer oil radiator to medium high pressure steam radiator.

Two. Radiator pressure rating:

Steam pressure can be roughly divided into: low pressure 2.5 MPA, medium pressure 3.5 MPA, high pressure 5.0 MPA, most of the park is based on medium pressure 3.5 MPA, through the steam pipeline to reach the finalizer is basically 3.0 MPA ~ 3.3 MPA

Three, temperature grade:

The oven can be divided into 170, 190 and 210 degrees according to different types of steam. Different steam pressure needs to be achieved through different process design and heat dissipation area to achieve oven temperature.

Four, radiator structure: roughly divided into 3 rows, 4 rows, 5 rows.

Five, core technologies:

(1) the heat dissipation effect of the radiator is different because of the different spacing of the radiator tubes.

(two) the radiator process determines the oven temperature, steam consumption and radiator service life.

(3) The throttling device at the outlet of the radiator can greatly increase the service life of the radiator and the drainage equipment.

(4) The heat dissipation effect of steel pipe with excessive wall thickness is not good, and the service life of steel pipe with thin wall thickness is too short, so the selection of wall thickness should be reasonable.

(five) the thickness of elbow should be changed from 1 to 2MM thick than steel tube wall. The way of elbow manufacture affects the service life of radiator.

(six) the welding of radiator is divided into two types: primer welding, surface welding and filler welding.

These six core technologies, so that the radiator function efficient, long-term use, has been recognized by the majority of customers; its heat dissipation effect is very significant, in the field of large heat industrial applications, play a significant role in the function of great significance; green, environmental protection governance is also of great value; erect radiator functionality, structure Design, product research and development technology, has been a leap forward; I believe that in the future, will make greater breakthroughs in growth.
