What can cause operational difficulties in a hydraulic system?

Operational difficulties in a hydraulic system can stem from several factors, with the quality and type of hydraulic fluid being a critical element. Using an improper fluid can lead to various issues, such as inadequate lubrication, poor heat transfer, and diminished system performance. If the fluid does not meet the required specifications—such as viscosity or chemical compatibility—it can result in increased wear on components, overheating, and even failure of the hydraulic system.

In addition, a faulty pressure control valve (PCV) can disrupt the fluid flow and pressure regulation necessary for efficient operation, while incorrect cracking pressures can lead to unintended system activation or failure to maintain required pressure levels. However, while these factors are significant, the specific mention of the improper fluid highlights its foundational role in ensuring the smooth functioning of the hydraulic system, making it a key concern for maintaining operational integrity.
