The piston sealing ring of an automatic coffee machine is a "key defense line" forpreventing leakage and maintaining pressure.
However,many users and manufacturers have found that the sealing ring gets stuck during use, causing coffee liquid to leak everywhere. When cleaning. the machine has to be disassembled.
In fact, this is mostly due to incorrect oil selection, especially neglecting the core point of "material compatibility".
The seal gets stuck and leaks?
Piston seals are usually made of materials such as nitrile rubber and silicone. If the oil is not compatible with the material, trouble will follow! Poor-quality oil will corrode the rubber, causing the sealing ring to swell, deform harden and crack, creating gaps in the originally tight sealing surface, and the coffee liquid will leak out naturally:
If the grease is poorly lubricated or clumps after reacting with the material. it will cause the piston to get stuck when moving up and down, the coffee machine to dispense liquid intermittently, and even trigger a fault alarm;
If non-food-grade oils seep in, they can contaminate coffee, violate food safety requirements, and pose a "fatal hazard" for commercial coffee machines.To address these issues, Baoxing multi-purpose food-grade waterproof grease can solve them!
Compatible with various sealing ring materials such as nitrile rubber and silicone, it does not corrode or swell, preventing sealing ring failure due to oil from the root;High adhesion grease forms a dense protective film on the sealing surface, which does not leak even when in contact with coffee liquid,effectively blocking leakage.
