With smooth fat needs to understand a few indicators

When demand for the product when choosing a smooth fat, should first understand the role of the smooth fat: anti-friction, sound attenuation, protection, sealing, etc. Anti-friction smooth fat, should consider the scope of the upper and lower temperature resistant load and rotating speed, etc. ; Sound smooth and fat, should think about adhesion, temperature range, load and speed, etc. Smooth protective grease, should consider to metal, non-metallic protective and compatibility; Smooth sealing grease, should be thinking about the compatibility with packing material. Should also be based on the structure of smooth parts of the products and environmental conditions of different to choose smooth fat, combined basically has the following several indicators: 1. Working temperature: smooth parts of the minimum operating temperature shall be higher than that of smooth fat line at low temperature, otherwise it will increase the resistance; The highest temperature should be lower than smooth fat high temperature line, otherwise will lose smooth due to smooth away the fat and ability; The highest applicable temperature should be lower than its normal smooth fat drop point 20 ~ 30 ℃. 2. Speed: smooth parts of the higher speed, smooth fat by the greater the shear stress, and part of the high speed regulated temperature rise is fast and easy to make smooth lost fat is thinning, and therefore should choose smooth consistency larger fat. 3. Bearing load: based on load selection smooth fat is one of the keys to ensure the smooth, smooth points should be chosen based on heavy load high oil viscosity, high content of thickener smooth fat; If both accept heavy load and impact load, should choose high extreme pressure and antiwear smooth fat, such as smooth fat containing molybdenum disulfide. 4. Use condition: environmental conditions refers to the working environment and smooth points around medium, such as air humidity, dust, and can have a corrosive medium, etc. In humid environment or under the condition of water contact, smooth fat can choose water resistance is good. Such as calcium base, lithium base; Tough conditions, should choose smooth with antirust added fat, and sodium based fat unfavorable choose poor water resistance; In a smooth point in the intense environment of chemical substances, should choose the fluorine element of resistance to chemical medium smooth grease, etc. ; More dust in the environment, can choose thick smooth fat containing graphite; To seal you have special request, should choose smooth sodium based grease. 5. Capital elements: when choosing smooth fat, but also thinking to use economy, comprehensive analysis using this smooth smooth after fat can prolong the cycle, charging times, fat consumption, bearing failure rate and maintenance cost, etc.
