Precautions for using gearbox lubricating oil
For the gearbox system with concentrated lubrication of thin oil, due to the strict temperature requirements of the lubricating oil or oil tank, a cooler (steam cooling) or cooling coil (water cooling) is usually used to cool it. Although gear oil is required to have good anti emulsification performance, the infiltration of a considerable amount of water into the oil can easily cause the oil to emulsify. When gear oil with extreme pressure anti-wear agents is emulsified, the additives are hydrolyzed or precipitated and separated, losing their original performance and producing harmful substances, causing the gear oil to rapidly deteriorate and lose its usability. Iron Ba lubricant engineers remind everyone that emulsified oil products cannot be continued to be used. For lubrication systems cooled by water (or steam), attention must be paid to preventing water (steam) leakage to avoid unnecessary damage to the gearbox.

2. For gearbox systems that use pumps for circulating lubrication, attention should be paid to the pressure difference of the pump and the filter screen should be cleaned in a timely manner. If the pressure difference of the pump is large in a short period of time, or the frequency of cleaning the filter screen increases significantly, and the amount of oil sludge and metal debris on the filter screen increases significantly, it indicates that the use of lubricating oil is not very good in a certain sense. In addition to material and design issues, it can be said that the selection of lubricating oil is not reasonable enough: firstly, the viscosity is not suitable enough, and secondly, heavy load can be used instead of medium load, that is, using a higher grade of gear oil will significantly improve the effect.
3. It is necessary to avoid mixing new oil with old oil (rather than replenishing oil according to regulations), or adding high viscosity oil to achieve a certain viscosity due to a decrease in viscosity. This approach may have some short-term effects, but the performance of the oil product will significantly decrease, and at the same time, the lubrication conditions of the equipment will deteriorate, leading to increased wear and tear, which in a sense will shorten the service life of the equipment. In addition, due to different main ingredients, there may be incidents of additive "fighting" when mixed, causing the intended effects of additives to cancel each other out, resulting in unimaginable consequences for the equipment.
Regarding the issue of oil change intervals, theoretically speaking, a short oil change period can better reduce friction pair wear and extend the service life of equipment, while providing a necessary condition for ensuring its normal operation. But from the perspective of economic benefits, oil products should be used more accurately and effectively. Whether to change the oil and when to change it, in addition to following the oil change period regulations, should also be considered based on factors such as the equipment's operating time and operating rate, in order to maximize the use of the oil product.
5. Regularly monitor the oil temperature, vibration, noise, and other issues of the oil equipment. When the lubrication conditions deteriorate and cause damage to the tooth surface, it can directly lead to a significant increase in vibration and noise.
