1. Adjust the pressure of different continuous pipeline flow according to different products to replace the consistent high-pressure steam heating method;
Whether it is a trigger machine or an automatic machine, when the steam valve is opened for heating, the continuous flow pressure of the pipeline is the most important, and it also needs to be changed. It needs to be changed according to the products of different densities, and the continuous pressure needs to be changed. 1.2-2 BAR, the automatic machine will be 1.2-2 BAR. The higher the density of the product, the lower the continuous pressure of the pipeline. In this way, not only the internal adhesion of the product is guaranteed, but also, the steam consumption is saved by 10-20% .
2, please try to use vacuum cooling;
Vacuum cooling and cooling water cooling have always been controversial topics for many foam factories. Many people may think that the cooling speed of water cooling is no slower than that of vacuum cooling. Therefore, many factories have not solved the low vacuum degree caused by the leakage of the mold, and It uses extremely low cooling water and a large amount of water cooling, but please pay attention: the mold is water-cooled, and the temperature when the product is ejected is about 40 degrees. Then, if vacuum cooling is used, the temperature when the product is ejected is about 80 degrees, please Just imagine, in the heating of the next mold, the 40-degree mold is heated to 110 degrees and the 80-degree mold is heated to 110 degrees. The steam consumption is very different. According to our test, a pair of 1400X1200X380 molds are water-cooled The difference in consumption with vacuum cooling is 1.5-2.5 kg/mold. This is quite a large number. Running 24 hours a day, a piece of equipment is the difference of 1500-2400 kg of steam.
