After lubricating the three blade roots blower with lubricating oil for a period of time, the performance decreases and the leakage increases. It needs to be supplemented or replaced in time. The fan has high oil content, so it is usually replaced every 3 months. Replacement depends on the quality of the lubricant.
No matter which method is used to change the oil, it is to ensure that the lubricating oil has proper performance. Therefore, the following simple methods can be used to identify the quality of lubricating oil. The lubricating oil will be oxidized and deteriorated due to the influence of air and other media during use. In order to judge the degree of desensitization and deterioration, the sludge deposited at the bottom of the oil tank can be put between the index finger and the thumb to rub against each other. If there is only more sludge and the adhesion is not strong, it is said that the oxidation of oil is not too serious, but it is not pure. Filtering is necessary. If you feel that there are many gums and strong adhesion, it means that the lubricating oil has deteriorated seriously and can no longer be used.
Mechanical impurities in the lubricating oil, including foreign suspended or insoluble substances, such as dust, sand and metal particles deposited in the oil, will damage the oil film and increase wear. When the sandfly containing impurities reaches a certain concentration, the lubricating oil cannot be used any more. According to experience, after the oil turns black, if the color of the filtered oil does not improve, it should be replaced.
Water will increase the corrosiveness of oil and make the oil aging; It is easy to form bubbles and make the oil lose its lubricity. Therefore, sand flies containing water 186 should be controlled. High quality lubricating oil shall not contain water. In practical application, under the condition of water cooling, the lubricating oil will deteriorate and become invalid due to the penetration of cooling water. To check whether there is water, clean and dry cotton yarn can be dipped into lubricating oil and ignited with fire. If there is water in the oil, it will explode or flash.
In case of serious oil leakage during the operation of the machine, pay attention to the residual lubricating oil in time to prevent insufficient and timely replacement, so as to ensure that the normal use of the three leaf roots blower is affected. The common method is to stop the sealing gasket and processing joint surface for a long time, remove and replace them, and achieve effective treatment during the operation of the equipment. It is very important to focus on the impact of such machines from multiple perspectives.
1. Check whether the lubricating oil of three blade roots blower contains other impurities. During inspection, a small amount of lubricating oil can be dipped with fingers. If there is obvious graininess, it needs to be replaced.
2. Check whether the lubricating oil has oxidized and deteriorated. If it has oxidized and deteriorated, identify it by appearance. At this time, the color of the lubricating fluid becomes darker or darker, and a hard glue film will form on the surface.
Various lubricating oils shall not be mixed, and new and old lubricating oils shall not be mixed. Therefore, when replacing lubricating oil, remove all waste lubricating oil first, and then add new lubricating oil. Many people think it is wasteful to pour out the old lubricating oil and use it together. This is how the normal use of the machine is affected.
3. Lubricants shall be supplemented properly. Too little fuel injection will cause insufficient lubrication.
To save time, do not add too much oil at a time, because too much oil will cause excessive agitation and rapid temperature rise, resulting in oil separation, decomposition and leakage.
I believe that after reading the above contents, you should also have a better understanding of the replacement cycle of Roots blower lubricating oil. I hope it will be helpful to you.
