Precautions for using reducer lubricant
1. For the thin oil centralized lubrication reducer system, due to the strict requirements of the lubricating oil or oil tank temperature, it is usually cooled by a cooler (steam cooling) or a cooling coil (water cooling). Although gear oil is required to have good anti-emulsification properties, after a considerable amount of water has penetrated into the oil, it is easy to emulsify the oil. After emulsification of gear oil with extreme pressure anti-wear agent, the additives are hydrolyzed or precipitated and separated to lose The original performance, and produce harmful substances, make the gear oil quickly deteriorate and lose its performance. Tieba Lubrication Engineer reminds everyone that emulsified oils should never be used. For water (or steam) cooling lubrication system, we must pay attention to prevent water (steam) leakage, so as to avoid unnecessary damage to the reducer.

2. For the reducer system that uses the pump for circulating lubrication, pay attention to the pressure difference of the pump and clean the filter in time. If the pressure difference of the pump is large in a short time, or the frequency of cleaning the filter screen is significantly increased, and the sludge and metal wear debris on the filter screen are significantly increased, it means that the use of the lubricant is not very good in a certain sense. In addition to material and design issues, it can be said that the selection of lubricants is not reasonable enough: first, the viscosity is not suitable enough, and second, heavy loads can be used instead of medium loads.
3. It is necessary to avoid mixing the new oil with the old oil (instead of replenishing the oil as required), or adding high viscosity oil to achieve a certain viscosity due to the decrease in viscosity. This may have some short-term effects, but the performance of the oil will be significantly reduced. At the same time, the lubrication conditions of the equipment will be worsened, which will cause increased wear and shorten the service life of the equipment. In addition, because of the different main agents, the additive “fighting” may occur when mixed, so that the additives should play a role in offsetting each other, and the consequences to the equipment are unthinkable.
4. Regarding the problem of oil replacement cycle, theoretically, the oil replacement period is short, which can better reduce the friction pair wear and prolong the service life of the equipment, while providing a necessary condition for ensuring its normal operation. However, from the perspective of economic benefits, oil products should be used more accurately and effectively. Whether to change oil and when to change it, in addition to following the oil change period, you should also consider the operating time and operating rate of the equipment to maximize the use of the oil.
5. Regularly monitor the oil temperature, vibration and noise of the oil equipment. When the tooth surface is damaged due to poor lubrication conditions, both vibration and noise can be directly strengthened.
