How to judge industrial gear oil deterioration and oil change intervals? <Seven>

Author: Industrial gear oil manufacturers - together Xuan Chemical 2015-02-07 10:11:16

在使用一段时间后,如何判断其是否变质,如何确定换油周期,确保齿轮正常有效工作,降低故障和维修次数? After using industrial gear oil, extreme pressure gear oil, heavy load gear oil, and reducer gear oil for a period of time, how to determine whether it has deteriorated, how to determine the oil change cycle, ensure that the gear works normally and effectively, and reduce the number of failures and maintenance? Hexuan provides you with references from the following aspects:

工业齿轮油-高温减速机齿轮油

1. Judgment of deterioration of industrial gear oil

1. Appearance change: The color becomes darker and more mixed, resulting in emulsification, obvious abrasive particles, mechanical impurities and sludge.

2. Viscosity change: The viscosity of oil containing viscosity index improver decreases due to mechanical shear, while the oxidation of oil and emulsified sludge will increase the viscosity;

3. Change in acid value: In oil products containing high acid value additives, the initial decrease in acid value indicates the consumption of additives, and the increase in acid value in the later period is the result of oxidation to produce acid products.

4. Moisture increase: Anti-emulsification performance becomes worse. Extreme pressure hydrolysis affects lubrication and may cause pitting and cementation of the tooth surface.

5, benzene, pentane (petroleum ether) insoluble matter increase: This is the long-term use of oil products, high temperature oxidation products and metal shavings, dust and other pollution results, is also commonly known as carbon deposits, sludge precipitation phenomenon .


Determination of gear oil oil change cycle

The determination of the oil change interval and the oil change index is a very complex issue, and it is related to the running-in of gears, the load of gears, the type and quality of gear oil, and the importance of lubricating parts in mechanical equipment.

1. Generally speaking, a gearbox with a small amount of oil can be regularly changed according to actual experience.

2. The oil replacement cycle of the gearbox without contact with water can reach 4000 ~ 5000 hours.

3. Large gears often use centralized lubrication systems. Due to regular oil replenishment, oil is often changed according to the quality of the oil.
