304 Stainless Steel Boiler Coils, Special-Shaped Coils, Coils Can Be Processed According To The Drawing

Generally speaking, stainless steel coils have different classifications according to their different fields of use. We can divide them into industrial use, mechanical structure use and fluid use. Among them, industrial coils are used in heat exchangers, boilers, petroleum, chemical and other fields; and stainless steel coils for fluids are mostly used in beverages, beer, milk, water supply systems and other fields; as for mechanical structures, coils are used. In fact, it is used more in the fields of printing and dyeing, printing, textile machinery, medical equipment, kitchen equipment and so on. The effects and functions of different types of coils are different.
Coil application range: boiler pressure vessel, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbow food and other industries.

Stainless steel coil processing manufacturer's experience in repairing and processing stainless steel coils and capillary tubes
1. The inlet of the capillary tube should be connected to the top of the evaporator coil. 2. After the freezer coil is not well controlled, the return air pipe outside the box will be frosted if the amount of refrigerant injection is not well controlled. You can put some refrigerant when the return air pipe condenses. 3. It is normal that the upper part of the coil does not form frost and the lower part does not form frost. During the test machine, there is no food to be frozen in the box, and the humid air content in the box is low, so only the upper part is frosted. It is normal for the lower part to feel smooth by hand. You can touch the lower tube with a towel wet with water. If the wet towel can stick to the tube, it proves that the refrigerant is just enough. If it does not stick or the hand feels no smoothness, then only check other Up.
4. The pitch of the coils is generally 5CM, and they are arranged naturally in layers from top to bottom. Choose 8-10MM copper tube. Note: Incorrect copper pipe arrangement will cause oil accumulation in the pipeline, which will cause sequelae such as poor circulation of the refrigeration system over time. 5. The inner diameter of the capillary tube is selected from 0.4mm to 1.78mm. Under normal circumstances, the refrigerator is selected between 0. 4-0. 6mm. The freezer is selected between 0. 6-0. 8mm. The refrigerated cabinet is selected between 0.8-1mm.
6. The length of the capillary tube: The freezer is at 2.8-4. 0m. The length of the capillary tube is not. It is determined according to the ratio of the high and low pressure ends after the refrigeration system is stable. The ratio of the high and low pressure ends is: 1. 5Mpa/0.06Mpa,.
7. The copper tube uses 8MM, and the length is determined according to the actual volume. The simple way is to use small-capacity refrigerators and freezers. The distance between the tubes is 4-6CM. For more than 300 liters, the separation distance is 8-10CM. The cooling can be made uniform, and the length can be calculated in advance. After the pipe is folded in half, the double pipes are coiled at the same time, so that the inlet and the outlet can be handled at the same position. As for the refrigerating room, just buy a finished blown-up type.
8. The cut-off flow rate of the capillary tube is directly related to the displacement of the compressor, and it also determines the working pressure of the condenser. So choose well. The empirical formula is: compressor power W*2=capillary length. After getting on the machine, fine-tune it according to the actual situation. Example 125w*2=capillary length 250.
9. Regardless of the length of the capillary tube outside the original box, keep the original length, and connect the capillary tube of the same specification with a length of 1. 2-1. 5m originally buried in the box body.
