The function of oil
The oil circulating in the lubrication system has the following functions:
The oil forms a continuous film of oil between all the friction surfaces of the moving parts to reduce friction between the parts.
The oil flows through the part working surface during the cycle, which can reduce the temperature of the part.
The oil can carry away the metal particles from the friction surface and wash away the deposits deposited on the cylinders, pistons, piston rings and other parts.
The oil film attached to the cylinder wall, piston and piston ring can seal and prevent leakage.
5) Rust prevention
The oil has the effect of preventing rust on the parts.
