General knowledge of the performance of electric hydraulic pump

We all know that the hydraulic oil is one of the main structures of the electric hydraulic pump and can guarantee the normal use of the machine. So how do you know about the performance of the hydraulic oil? Let's take a look at it together:
(1) Good abrasion resistance: The anti-wear property is not related to the viscosity, but by adding additives to the oil to form an oil film on the paired surface of the friction pair to achieve the property of reducing wear. High viscosity does not necessarily have good lubricating properties. , Such as silicone oil, but if the viscosity is low, the liquid film is too thin to cover the surface roughness, bad abrasion resistance, such as water.
(2) Appropriate viscosity and good viscosity-temperature characteristics: Excessive viscosity will cause increase of viscous resistance loss, large temperature rise, poor suction performance of the pump, difficulty in starting, and even cavitation. Control sensitivity will drop. Viscosity will be too low. Increased leakage, reduced volumetric efficiency, reduced control accuracy, thinning of the liquid lubricating film, and even the inability to form liquid lubricants to aggravate wear.
(3) Good anti-emulsification and hydrolysis stability: The ability of oil to resist the formation of emulsion by mixing with water is called anti-emulsification. The ability of oil to react with water to decompose is called hydrolytic stability. Water is a hydraulic jack. A contaminant in the system is brought into the system by the humid air from the breather hole of the tank or the cylinder rod retraction.
(4) Good oxidation stability and thermal stability: Oxidation stability refers to the ability of the oil to resist oxidation. The oil is oxidized by heat, oxygen in the air, water and metal substances and generates organic acids and polymers. , The color of the hydraulic oil becomes darker, the acid value increases, the viscosity changes, and the precipitation material is generated, so the corrosiveness of the hydraulic oil increases, the pores of the hydraulic element are clogged, and the abrasion is aggravated.
