，更換周期可延長至4000小時以上。此外，環(huán)境溫度對油品壽命影響顯著，高溫環(huán)境會加速添加劑消耗，需縮短換油間隔。

　　The working conditions are the determining factor. Under continuous high load operation, the temperature rise of gear oil is faster and the oxidation rate is accelerated. It is usually recommended to replace it every 2000 to 3000 hours. If the equipment is in intermittent operation or light load state, the deterioration rate of the oil will slow down, and the replacement cycle can be extended to more than 4000 hours. In addition, environmental temperature has a significant impact on the lifespan of oil products, and high temperature environments can accelerate the consumption of additives, requiring a shorter oil change interval.

　　油品質(zhì)量與監(jiān)測手段同樣關(guān)鍵

。優(yōu)質(zhì)齒輪油采用深度精制基礎(chǔ)油與復(fù)合添加劑配方，抗磨損、抗氧化性能更優(yōu)，可延長使用周期。定期通過油樣檢測評估油品狀態(tài)，如粘度變化、酸值升高、金屬顆粒含量等指標，能更精準判斷更換時機。若檢測結(jié)果顯示油品性能衰減超過20%，即使未達理論周期，也應(yīng)提前更換。

　　The quality of oil products and monitoring methods are equally crucial. High quality gear oil is formulated with deeply refined base oil and composite additives, which have better anti-wear and anti-oxidation properties and can extend the service life. Regularly evaluating the condition of oil products through oil sample testing, such as changes in viscosity, increased acid value, and metal particle content, can more accurately determine the timing of replacement. If the test results show that the performance of the oil has deteriorated by more than 20%, even if it has not reached the theoretical cycle, it should be replaced in advance.

　　設(shè)備維護水平亦不可忽視。密封系統(tǒng)的完好性直接影響油品污染程度

，若存在漏油或外部雜質(zhì)侵入，需縮短換油周期并排查密封件。同時，定期清理油路濾網(wǎng)
