Compared to other products, EHV electric pump What are the advantages?

Why do we choose ultra-high pressure electric pump, rather than other similar products, because the high-pressure electric pump itself has obvious advantages. Today, Xiaobian for everyone to interpret what are the advantages of high pressure electric pump? Compared with other products, the advantages of high pressure electric pump? 1, the appropriate viscosity, good viscosity-temperature properties Viscosity is the choice of hydraulic oil First of all considerations, under the same working pressure, the viscosity is too high, hydraulic components increased resistance to movement, heating to speed up the self-priming pump capacity decreased, the pipeline pressure drop and power loss increases; if the viscosity is too low, will increase the hydraulic pump Of the volume loss, leakage within the component increases, and the sliding member thinning of the oil film, bearing capacity decreased. 2, good lubricity, anti-oxidation Hydraulic system has a large number of moving parts need lubrication to prevent the relative movement of the surface wear, high pressure electric pump, especially high pressure system, the wear resistance of hydraulic oil to be high many. The hydraulic oil will also be oxidized during use. The acidic substances produced by the oxidation of the hydraulic oil will increase the corrosiveness to the metal. The generated sludge will clog the filter and the small gap so that the hydraulic system will not work normally. Therefore, it is required to have Good oxidation resistance. 3, good anti-shear stability and corrosion resistance As the hydraulic oil through the pump, Valve orifice and cracks, to undergo severe shear effect, leading to some of the oil in the macromolecular polymer such as tackifier molecular rupture , Become small molecules, so that the viscosity decreases, when the viscosity decreases to a certain extent the oil can not be used, so requires good shear resistance. Hydraulic oil in the course of the inevitable to contact with water and air and oxidation of the acidic substances will rust and corrosion of metals, affecting the normal operation of the hydraulic system. 4, good anti-emulsification and sealing material adaptability Hydraulic oil in the course of work from different ways of mixing water and condensate in the hydraulic pump and other components. Due to the poor adaptability of the hydraulic oil and the sealing material, the sealing material will expand, soften or harden and lose the sealing performance, so the hydraulic oil and the sealing material are required to be mutually compatible. 5, good anti-foam and air release In the hydraulic tank, due to mixed with oil bubbles in the oil circulation, will not only reduce the system pressure, lubrication conditions deteriorate, but also have abnormal noise, vibration, in addition to bubbles It also increases the area of ​​oil in contact with air and accelerates the oxidation of the oil, thus requiring a good anti-foam and air release properties of the hydraulic oil.
