What are the hazards of cavitation in hydraulic systems? How to prevent it?

2025-04-28

Cavitation can cause serious damage to the hydraulic system: it can produce knocking noise in the axial piston pump, damage the valve plate and cylinder surface. It can reduce the volumetric efficiency of the pump, resulting in flow and pressure fluctuations. It can accelerate the oxidation of the oil and produce acidic substances that corrode metal parts. Measures to prevent cavitation include: ensuring that the suction pipeline is unobstructed, the pipe diameter is large enough, and reducing elbows and valves. Keep the oil level in the oil tank high enough, and the suction port immersion depth is not less than 200mm. Control the oil temperature within an appropriate range to avoid gas precipitation in the oil. Select oil with good anti-cavitation performance and add anti-foaming agent when necessary. For high-speed pumps, consider using a booster tank or an auxiliary oil supply pump. Check the condition of the suction filter regularly to avoid blockage and increase resistance. When designing the system, ensure that the pump suction port pressure is not less than 0.8bar (absolute pressure).
