How to choose suitable lubricating oil for the ZQ400-20.49-1 reducer in a high humidity environment

In high humidity environments, choose suitable ZQ400-20.49-1 the lubricating oil for the gearbox needs to consider the following aspects:

Has anti rust and anti-corrosion properties: In high humidity environments, lubricating oil easily absorbs moisture, causing rusting and corrosion of metal parts inside the gearbox. Lubricants containing rust and corrosion inhibitors, such as ISO MH grade or higher, should be selected. These additives can form a protective film on the metal surface, preventing moisture and oxygen from coming into contact with the metal and preventing rust and corrosion.

Appropriate viscosity: Viscosity is an important physicochemical indicator of gear oil. ZQ400-20.49-1 reducer is generally used for low-speed and heavy-duty working conditions, and is usually suitable for selecting lubricating oil with high viscosity. You can refer to the equipment manual or based on experience. For example, when the ambient temperature is between 0 ℃ and 30 ℃ and the output shaft speed is below 100 revolutions per minute, 220 gear oil can be used.

Good anti emulsification performance: In high humidity environments, moisture is easily mixed into lubricating oil. If the anti emulsification performance of lubricating oil is poor, it will form emulsion, destroy the formation of oil film, and reduce the lubrication effect. Therefore, it is necessary to choose lubricating oil with good anti emulsification performance, which can quickly separate the water entering the oil and maintain the stability of the lubricating oil performance.

Anti oxidation and anti foam performance: during gear movement, the lubricating oil will be continuously stirred and contacted with oxygen, which is easy to oxidize and produce foam. The selection of lubricating oil added with antioxidant and anti foam agent can improve its oxidation stability and anti foam property, extend the service life of lubricating oil and ensure the lubricating effect.

High quality base oil: The quality of base oil has a significant impact on the performance of lubricating oil. In high humidity environments, it is recommended to choose synthetic oil or high-quality mineral oil as the lubricating oil for the base oil. Synthetic oil has better chemical stability, antioxidant properties, and low-temperature flowability, which can better adapt to harsh environments; High quality mineral oil can also meet certain usage requirements through fine refining and additive blending.

In addition, it is necessary to comprehensively consider factors such as the working temperature and load conditions of the gearbox. At the same time, it is also very important to refer to the recommendations of equipment manufacturers.
