The winter climate in the Northeast is cold and the temperature is low, which puts forward special requirements for the lubricating oil of machinery and equipment. In such extreme environments, lubricants need to have higher cold resistance to ensure that equipment can operate properly in severe cold conditions. Today, Uni-President Engine Oil has made a collection of some content and communicated with you little by little.
1.Lubricating oils need to maintain good flow properties at low temperatures.
In the winter in the Tohoku region, temperatures can drop below zero or even lower, and general lubricants can easily become viscous at this extreme low temperature, causing equipment to not function properly. Therefore, according to the characteristics of the winter climate in Northeast China, it is recommended to use engine oil starting with 0w or 5w, which can still maintain good fluidity under extremely cold conditions. Lubricants need to have good low-temperature fluidity to ensure effective lubrication of equipment in extremely cold environments. While considering low-temperature performance, it is also necessary to pay attention to the viscosity grade of the oil at operating temperature. For example, common viscosity grades include 5ww-40, etc. Make sure that the viscosity of the oil you choose meets the manufacturer's recommended standards. Ensuring that the oil you choose meets API (American Petroleum Institute) or ACE (European Automobile Manufacturers Association) standards can help guarantee its quality and performance.
2.Lubricants need to have good oxidation resistance at low temperatures.
In an extremely cold environment, the equipment will produce large frictional heat when running, which will easily lead to the oxidation of the lubricating oil, thereby reducing the lubrication effect. Therefore, in order to ensure that the equipment can be effectively lubricated and protected in extremely cold environments, the lubricating oil needs to have good oxidation resistance to prolong the service life of the lubricating oil and maintain its good lubrication effect.
3.Lubricants also need to have good sealing properties at low temperatures.
In the winter of Northeast China, the air is dry, which can easily lead to the hardening and aging of the seals of the equipment, which will affect the sealing effect of the equipment. Therefore, the lubricating oil needs to have good sealing performance to ensure that the equipment can maintain a good sealing state in the extremely cold environment, and avoid the leakage of lubricating oil due to the aging of the seals, which will affect the normal operation of the equipment.
Tongyi Oil is deeply aware that the winter climate in Northeast China has put forward special requirements for lubricating oil, and lubricating oil needs to have good low-temperature fluidity, oxidation resistance and sealing performance to ensure that the equipment can be effectively lubricated and protected in an extremely cold environment to ensure the normal operation of the equipment. Therefore, when using lubricating oil in winter in Northeast China, it is necessary to select a lubricating oil with good low-temperature performance according to the local climate characteristics to ensure that the equipment can be effectively lubricated and protected in an extremely cold environment.
