    1. Product Details
    2. Applicable Scene

    Cavitation in hydraulic systems can be a serious issue, especially in high-flow applications. It occurs when the pressure of a fluid drops below its vapor pressure, leading to the formation of vapor bubbles that can collapse and cause damage to hydraulic pumps and other components. Understanding and addressing cavitation is essential for ensuring the reliability and efficiency of hydraulic systems. Here, we will explore the causes of cavitation and provide practical solutions to mitigate its effects.

    Understanding Cavitation

    Cavitation typically occurs in areas where there is a significant drop in pressure, such as at pump inlet or within narrow passages and fittings. When the pressure falls below the vapor pressure of the fluid, vapor bubbles form. As these bubbles move to regions of higher pressure, they collapse violently, generating shock waves that can cause erosion, increased wear, and even catastrophic failure of the pump. In high-flow applications, the risks associated with cavitation are amplified due to the increased velocity of the fluid flow, which can lead to greater pressure fluctuations.
    Causes of Cavitation
    Several factors contribute to the occurrence of cavitation in hydraulic systems, including:
    Low Inlet Pressure: Insufficient pressure at the pump inlet can result from improper system design, elevation differences, or blockages in the suction line.
    High Fluid Temperature: Higher temperatures can reduce the fluid’s density and increase its vapor pressure, making it easier for cavitation to occur.
    Pump Misalignment: Misaligned pumps can cause significant pressure drops, leading to localized cavitation.
    Viscosity Changes: Variations in fluid viscosity can affect the flow characteristics, potentially causing pressure drops in certain areas of the circuit.
    Excessive Flow Velocity: High flow rates can lead to turbulence and increased pressure drops, increasing the likelihood of cavitation.
