Cavitation Phenomenon Of Hydraulic Pump

Cavitation phenomenon of hydraulic pump refers to the pump into the air, oil can not fully fill the pump space, resulting in bubbles in the oil, the work of the hydraulic pump has serious harm. If the inlet pipe of the hydraulic pump is very narrow, the pressure of the oil will be reduced. Thus creating the popping effect! Pressure can be up to 1000kgf/cm square. Enough to peel off metal particles from parts and make a loud noise. If the cavitation occurs on the pump, the hydraulic pump will cause serious damage. At the same time, the pressure drop separates the air dissolved in the hydraulic fluid and creates cavitation. When these bubbles are pushed to high pressure, they compress and cause them to collapse. It was accompanied by loud noises and vibrations. So how to reduce this phenomenon? First, the hydraulic station should be used correctly to reduce the pressure difference before and after the valve hole. The second is to connect all parts, so that close and reliable, strictly prohibit air intrusion. It is crucial to use a good bubble working medium. So as to reduce the harm of cavitation and chemical corrosion, cavitation, etc.
