What can cause hydraulic fluid to become contaminated?

Hydraulic fluid contamination occurs primarily when foreign substances are introduced into the hydraulic system. The presence of dirt, water, or air can significantly degrade the quality of the hydraulic fluid, which is essential for the system's proper operation.

Dirt can originate from various sources, such as unclean environments or improper handling during maintenance. Water can enter the system through condensation or leaks, leading to corrosion and reduced lubrication effectiveness. Air can create issues such as aeration, which can compromise the hydraulic fluid's ability to transmit power efficiently.

Thus, the introduction of these contaminants is a critical concern because they can lead to performance issues, increased wear on internal components, and ultimately failure of the hydraulic system. Regular monitoring and taking preventive measures against contamination are crucial for maintaining the integrity and functionality of hydraulic equipment.
