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

    升降机使用残次液压油压回油哪些影响?

    液压油是升降机的“血液”,也是传递能量的介质,通过液压传动然后使得上升或下降,液压油是重要的作业介质,在升降机中起着体系光滑、能量传递、防腐、防锈、冷却等作用,液压油的质量直接影响升降机的运用寿命和能否正常作业。其功能好坏直接决定了升降机作业效率和运用寿命,为什么说选择残次液压油不可取呢?下面就为大家讲解一下。

    残次液压油的缺点和体现:现在,市场上出现很多残次山寨液压油,他们大多是小作坊产品,是无良商人经过简略的工艺从废弃机油或废弃液压油中提炼出来的。

1、残次液压油中,水分含量较高,含有较多水分的液压油长期运行会加快油品的老化,发生锈蚀或腐蚀金属,油中带水后会使油品乳化,光滑性明显下降,加快液压体系老化,下降升降机运用寿命;黏度是液压油的一个重要目标,而残次液压油黏度一般都达不到国家标准。

2、残次液压油与正规厂家生产的液压油相比,色泽浑浊,粘度高,杂质多,水分含量高、缺少必要的化学添加剂,而好的液压油,无色无味,像纯净水一样通明,他们里面都添加了抗磨剂,能够削减液压体系特别是液压泵的磨损,延长升降机运用寿命,而残次液压油中,则不含抗磨剂,运用残次液压油,能加快液压体系部件磨损,下降液压升降机液压体系运用寿命。

3、有些黏度过低,黏度过低时,容易形成液压体系走漏,液压体系无法正常作业。黏度过高时,力传递效率下降,液压油活动速度下降,油泵排油量削减,液压升降机升降速度下降,黏度过高时,液压升降机不下降,好的液压油,适当的温度差对液压油的黏度影响较小,残次液压油,对温度比较敏感。因此我们能够看出,残次液压油对升降机的影响非常大。

    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.
