  • Symptoms of Common Hydraulic Problems and Their Root Causes

    When fluid moves from an area of high pressure to an area of low pressure without performing useful work (pressure drop), heat is generated. This means that any component that has abnormal internal leakage will increase the heat load on the system. This could be anything from a cylinder that is leaking high-pressure fluid past its piston seal
