What are the four ways of hydraulic cleaning and filtering?

• A. Flushing, Purging, Purifying, Recirculation
• B. Flushing, Purging, Purifying, Filtering
• C. Flushing, Purging, Filtration, Recirculation
• D. Flushing, Purging, Purifying, Circulation

Answer: (A)

Hydraulic cleaning and filtering use four distinct actions to remove contaminants and air from the system. Flushing pushes a large amount of fluid through the circuit to carry debris out of passages and toward the waste path, effectively sweeping contaminants out. Purging focuses on removing trapped air and any residual contaminants by directing flow or applying pressure so the lines fill with clean fluid and there are no air pockets that could cause cavitation or uneven pressure. Purifying is the actual removal of impurities from the fluid, typically accomplished with filtration media that capture solid particles as the fluid passes through. Recirculation involves looping the hydraulic fluid back through the system and especially through the filtration loop so contaminants are continually drawn out and filtered until the fluid meets cleanliness standards. When these four actions are combined, the system is cleaned both of physical debris and of dissolved or entrained contaminants, ensuring reliable hydraulic performance.
