Tips: Hydraulic electric pump function

The hydraulic electric pump has excellent anti-foaming and air release properties. In the hydraulic oil tank of the electric hydraulic pump, because the air bubbles mixed into the oil circulate with the oil, not only the pressure of the system will drop, the lubrication condition will deteriorate, but also abnormality will occur. In addition, the air bubbles increase the contact area between oil and air, and accelerate the oxidation of oil, so hydraulic oil is required to have excellent anti-foaming and air release properties.

Strong shear resistance: When hydraulic oil passes through the electric hydraulic pump, valve saving openings and gaps, it must experience severe shearing action, causing some macromolecular polymers in the oil, such as the molecules of the tackifier, to crack and become small molecules , to reduce the viscosity. When the viscosity drops to a certain level, the oil cannot be used, so it is required to have excellent shear resistance.

Excellent oxidation resistance. Hydraulic oil will also oxidize during use. Acidic substances generated after the oxidation of hydraulic oil will increase the corrosiveness to metals. The generated sludge deposits will block filters and small gaps, making the hydraulic system work. It is not normal, so the electric hydraulic pump is required to have good oxidation resistance.
