What is the effect of using inferior hydraulic oil for lift–升降机使用劣质液压油有什么影响
What are the effects of the use of defective hydraulic oil in the lift?
Hydraulic lift “blood”, is also the transfer medium of energy, by hydraulic drive and then make up or down, the hydraulic oil is an important work medium, plays a very smooth, energy transfer system in the elevator, anti-corrosion, rust and cooling effect, such as hydraulic oil quality can directly affect the use life of the elevator and normal operation. Its function directly determines the lift efficiency and service life, why choose residual hydraulic oil is not desirable? Here’s how.
The disadvantages and embodiment of defective hydraulic oil: now, there are many defective shanzhai hydraulic oil on the market, they are mostly small workshop products, unscrupulous businessmen through a brief process from the waste oil or waste hydraulic oil extracted.
1、In residual hydraulic oil, the water content is higher, the hydraulic oil with more water will speed up the aging of the oil, corrosion or corrosion of metal, oil with water will make the oil emulsification, smoothness significantly decreased, accelerate the aging of the hydraulic system, decline lift service life; Viscosity is an important target of hydraulic oil, and the viscosity of residual hydraulic oil is generally not up to the national standard.
2、Defect of the hydraulic oil compared with normal manufacturer production of hydraulic oil, turbidity of colour and lustre, high viscosity, impurities, high water content, the lack of the necessary chemical additives, and a good hydraulic oil, colorless, tasteless, lit as pure water, them have added anti-wear agent, can cut a hydraulic system especially the wear of hydraulic pump, extend the life of the elevator use, and the defect of hydraulic oil, excluding anti-wear agent, using defect hydraulic oil, to speed up the hydraulic system parts wear, falling hydraulic lift hydraulic system using life.
3、Some viscosity is too low, viscosity is too low, easy to form a hydraulic system leakage, hydraulic system can not work properly. When the viscosity is too high, the force transfer efficiency drops, the hydraulic oil activity speed drops, the oil pump discharge decreases, the hydraulic elevator lifting speed drops, when the viscosity is too high, the hydraulic elevator does not drop, the good hydraulic oil, the appropriate temperature difference has little impact on the viscosity of the hydraulic oil, residual hydraulic oil, more sensitive to temperature. Therefore, we can see that the residual hydraulic oil on the lift is very large.
