Hydraulic pump cavitation is a common problem in fluid handling systems, particularly in construction vehicles where hydraulic systems play a crucial role in various operations. Cavitation can result in reduced efficiency, increased wear and tear on components, and even catastrophic failure if not addressed promptly. Here’s how to troubleshoot this issue effectively.

Understanding Cavitation
11095066
Cavitation occurs when the pressure in the hydraulic fluid drops below the vapor pressure, leading to the formation of vapor bubbles. These bubbles can collapse violently, causing shock waves that damage the pump and other components. Indicators of cavitation include unusual noise from the pump, decreased performance, and fluctuating pressure readings.
Identify Symptoms
Begin by observing the symptoms associated with cavitation. Common signs include:
Increased noise or a “gravel” sound from the pump.
Significant loss of pressure or power.
Visible leaks or fluid discharge.
Overheating of the hydraulic fluid.
Document these symptoms for a more comprehensive understanding of the problem and how it affects the handling system.
Inspect the Hydraulic Fluid
The type and condition of hydraulic fluid can significantly impact the performance of the system. Check the following:
Fluid viscosity: Ensure that the fluid used meets the vehicle manufacturer’s specifications. Using the incorrect viscosity can lead to inadequate lubrication and increased cavitation.
Contamination: Inspect the fluid for contamination, such as dirt or water. Contaminated fluid can cause pump wear and cavitation issues.
Temperature: Monitor the fluid temperature. High temperatures can lower fluid density, leading to cavitation.
Check Pump Sizing and Configuration
An incorrectly sized or configured hydraulic pump can cause cavitation. Ensure the following:
Proper sizing: Use hydraulic pumps that meet the system parameters. Oversized or undersized pumps can lead to pressure drops and cavitation.
