Hydraulic oil is the working medium of the elevator and plays the role of system lubrication, anti-corrosion, rust prevention, cooling, etc. The quality of hydraulic oil will greatly affect the working reliability and service life of the hydraulic system of the lifting platform. Here I will elaborate the influence of inferior hydraulic oil on elevators from several aspects.

1.黏度是液壓油的一個(gè)重要指標(biāo)，適宜的粘度及良好的粘溫性能，以確保在工作溫度發(fā)生變化的條件下能準(zhǔn)確、靈敏地傳遞動(dòng)力，并能保證液壓元件的正常潤滑。黏度過低時(shí)，容易造成液壓系統(tǒng)泄漏，液壓系統(tǒng)無法正常工作。黏度過高時(shí)，力

1. Viscosity is an important indicator of hydraulic oil. Proper viscosity and good viscosity temperature performance can ensure accurate and sensitive transmission of power under the condition of changing working temperature, and ensure normal lubrication of hydraulic components. When the viscosity is too low, it is easy to cause the hydraulic system to leak and the hydraulic system cannot work normally. When the viscosity is too high, the force

傳遞效率降低，液壓油流動(dòng)速度降低，油泵排油量減少，升降機(jī)升降速度降低。

The transmission efficiency is reduced, the flow speed of hydraulic oil is reduced, the oil discharge of the oil pump is reduced, and the lifting speed of the elevator is reduced.

2.劣質(zhì)液壓油顏色渾濁、粘度高、雜質(zhì)多、水分含量高、缺少必要的化學(xué)添加劑；而好的液壓油，無色無味，里面都添加了抗磨劑，能減少液壓系統(tǒng)特別是液壓泵的磨損，延長液壓升降平臺(tái)使用壽命。

2. Poor quality hydraulic oil has turbid color, high viscosity, many impurities, high moisture content and lack of necessary chemical additives; Good hydraulic oil is colorless and tasteless, and anti-wear agent is added in it, which can reduce the wear of hydraulic system, especially hydraulic pump, and prolong the service life of hydraulic lifting platform.

3.劣質(zhì)液壓油中，水分含量較高，容易產(chǎn)生銹蝕或腐蝕金屬，會(huì)使油品乳化，潤滑性明顯下降，加速液壓系統(tǒng)系統(tǒng)老化，降低液壓升降平臺(tái)使用壽命；好的液壓油具有良好的防銹性，在高溫高壓條件下不易氧化變質(zhì)，使用壽命長。

3. In low-quality hydraulic oil, the water content is high, which is easy to rust or corrode metal, which will make the oil emulsion, significantly reduce the lubricity, accelerate the aging of the hydraulic system, and reduce the service life of the hydraulic lifting platform; Good hydraulic oil has good rust resistance, is not easy to be oxidized and deteriorated under high temperature and pressure, and has a long service life.
