Under what circumstances would a direct cooling block ice machine cause freon leakage?
Direct cooling block ice machines leaking refrigerant is usually caused by damage to the refrigeration system's sealing, with common reasons including welding defects, material aging, mechanical damage, and corrosion, among which poor welding and component aging due to long-term operation are the main contributing factors.
Analysis of common causes of fluorine leakage
Welding point issues
If refrigeration pipes are not properly welded during manufacturing or maintenance, they may develop sand holes, cracks, or cold welds, and after a period of use, leakage is likely to occur. This is one of the main causes of fluoride leakage in new or repaired equipment.
Material defects and corrosion
The evaporator or the metal materials connecting the pipelines may have original defects such as sand holes or cracks; During long-term operation, the metal surface is eroded by moisture, salt, or impurities, gradually forming micropores and causing slow Freon leakage. Especially in high-humidity or salty environments, the risk of corrosion increases significantly.
Mechanical damage and vibration
During transportation, installation, or operation, equipment is subjected to impact or vibration, which may cause pipeline deformation, loose joints, or weld cracks, thereby causing fluorine leakage.
Sealing aging
Rubber sealing rings and O-shaped gaskets in the system harden and lose elasticity over time, especially in high-temperature environments, where sealing performance declines and leakage is likely at the joints.
Improper installation
Failure to follow proper procedures during installation—such as not vacuuming and allowing moisture to enter the system, loose connections, or stress assembly—can all pose risks of fluorine leakage.
Impurities within the system and high temperatures
Impurities such as metal shavings, dust, or sealing blocks mixed into the refrigeration system can accelerate wear of the sealing ring; At the same time, continuous high-temperature operation (such as compressor overheating) accelerates the aging of rubber parts, forming a vicious cycle of "high-temperature → seal failure→ fluoroscourge leakage→ hotter."
