Factors of Hydraulic Cylinder Cavitation

Hydraulic pump station system in the hydraulic cylinder cylinder barrel wall, piston or piston rod surface some honeycomb-shaped holes, which are caused by cavitation. Cavitation will cause the cylinder barrel and piston rod mating surface becomes rough, the hydraulic cylinder produce internal leakage, the working speed is reduced. When cavitation and other forms of corrosion together, will accelerate the corrosion rate of the main parts of the hydraulic pumping station system, thus seriously affecting the normal use of construction machinery.

Factors affecting cavitation.

In the hydraulic cylinder parts surface and hydraulic oil relative movement, dissolved in the hydraulic oil gas is easy to precipitate and form bubbles. These bubbles flow to the high-pressure area after the rupture, the instantaneous generation of high-temperature and high-pressure micro-jet and impact repeatedly act on the surface of the hydraulic cylinder parts, the surface of the parts to produce cavitation. Hydraulic cylinder cavitation conditions with the hydraulic pump station system structure, hydraulic cylinder parts materials, hydraulic oil quality, manufacturing and maintenance aspects have a certain relationship.
