The influence of hard particles
Larger particles can cause sudden failure due to severe indentation, scratches and clogging
The deposition of smaller particles can cause valves to get stuck
, Smaller particles cause performance degradation due to abrasion

Influence of soft particles
, wrapped on the surface of the heat exchanger, causing high temperature
Influence of water< br/> , corrosion, reducing the surface performance of components, and allowing rust particles to enter the system
, reacting with certain additives to produce harmful substances, accelerating oil deterioration
, synthesizing acidic products with oxides, changing the fluid Properties
, Emulsify oil and reduce lubrication performance
, Water droplets freeze under low temperature conditions, causing system failure
Influence of air
Oil in hydraulic lubrication systems often contains a certain amount of Air, they are either dissolved or suspended, and their solubility is directly proportional to the pressure and inversely proportional to the temperature
, causing cavitation, aggravating the erosion and damage of the component material surface
, slow and unstable operation response, and increasing power Consumption
, oil oxidation, reduced lubrication performance, increased acid value
, reduced oil volume elastic modulus and stiffness
, increased noise
Impact of pollutants on components It will cause oil pump wear, high temperature, reduced efficiency, slow movement, oil leakage, valve stuck and other faults.
Impact on oil pump
The oil pump is one of the most sensitive components to contaminants. Hard contaminants will cause wear on the relatively moving parts. Particles with the same size as the gap will aggravate the wear of the pump, leading to increased leakage. Large, the temperature increases and the efficiency decreases.
Impact on hydraulic valves
Hydraulic valves are very sensitive to particles, which can easily cause wear and adhesion of the sliding surface and control port, causing the valve to react slowly, become unstable or get stuck.
Effects on oil cylinders
Contaminants will accelerate the wear of seals, causing oil leakage, failure and other failures.
