Electric Hydraulic Pump What Good Performance

May 13, 2023

Performance 1, appropriate viscosity, good viscosion-temperature characteristics, viscosity is the first factor to consider when choosing hydraulic oil, under the same working pressure, viscosity is too high, the hydraulic component movement resistance increases, the temperature increase the self-priming capacity of the hydraulic pump decreases, the pipeline pressure drop and power loss increases; If the viscosity is too low, it will increase the volume loss of the hydraulic pump, increase the leakage in the components, and make the oil film of the sliding parts thinner, and reduce the supporting capacity.
Performance 2, good lubrication (wear resistance), hydraulic electric pump has a large number of moving parts need lubrication to prevent wear on the relative moving surface, especially the high pressure system, the wear resistance of hydraulic oil is much higher requirements.
Performance 3, good oxidation resistance, hydraulic electric pump in the process of use will also occur oxidation, the acid produced by the oxidation of hydraulic oil will increase the corrosion of metal, the sludge precipitate will plug the filter and small gaps, so that the hydraulic system is not working properly, so it requires good oxidation resistance.
Performance 4, good shear stability, due to the hydraulic oil through the pump, valve orifice and gap, to undergo severe shear action, resulting in some large molecular polymers in the oil such as viscosifier molecular fracture, into small molecules, so that the viscosity is reduced, when the viscosity is reduced to a certain degree of oil can not be used, so the requirements have good shear resistance.
