What are the effects of lift using residual hydraulic oil?
Hydraulic oil is the “blood” elevator, also is 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, anticorrosive, antirust, cooling etc, refers to the gallery of hydraulic oil can directly influence the use life of the elevator and normal operation. The quality of its function directly determines the operating efficiency and service life of the lift, why said residual hydraulic oil can not be used?
Disadvantages and embodiment of residual hydraulic oil:
Now, there are a lot of residual copycat hydraulic oil on the market, most of them are small workshop products, unscrupulous businessmen after rough process from the waste oil or waste hydraulic oil extracted.
(1) residual hydraulic oil, water content is higher, containing more hydraulic oil long-term operation will accelerate the aging of oil, corrosion or corrosion of metal, oil with water will make the oil emulsification, smoothness significantly decreased, accelerate the aging of the hydraulic system, reduce the service life of the lift; Viscosity is an important target of hydraulic fluid, and the viscosity of residual hydraulic fluid is generally not up to the national standard.
(2) defect of the hydraulic oil, compared with normal manufacturer production of hydraulic oil color turbidity, high viscosity and impurities, high water content, the lack of the necessary chemical additives, and a good hydraulic oil, colorless, odorless, transparent like water, they are inside, add the anti-wear agent, can reduce hydraulic system especially the wear of hydraulic pump, prolong the service life of the elevator, and defect of hydraulic oil, excluding anti-wear agent, using the defect hydraulic oil, to speed up the hydraulic system parts wear and tear, drop hydraulic lift hydraulic system using life.
(3) some of the viscosity is too low, the difficulty is too low, easy to form the hydraulic system, hydraulic system can’t normal operation, high viscosity, the force transfer efficiency drops, the hydraulic oil activity rate drop, the oil pump oil discharge volume reduction, hydraulic hoist lifting speed drop, high viscosity, hydraulic lift is not falling, good hydraulic oil, the appropriate temperature difference on the viscosity of the hydraulic impact is small, defect of the hydraulic oil, is more sensitive to temperature, as a result, we can see that defect hydraulic oil to the influence of the elevator is very big.
