Whole life cycle of paper machine lubrication management

Paper machine lubrication 2020 - total life cycle management 06 - Shi jie 04 ( University of science and technology of China) 1 lubrication now the trend of papermaking equipment, papermaking industry is more do more sophisticated, run faster and faster speed, but the oil box more do more small, which means to reduce oil consumption. On the paper machine, lubricating oil in addition to the function of lubrication, cooling, antirust effect also, so the less oil, means that the greater the pressure. From the paper production process as well as the paper factory equipment selection, is basically the same, but demand for oil is more and more high. In different link, the demand for oil is not the same. Such as in the cadre is resistant to high temperature and oxidation. In oil use, there is a 'law of 60 degrees, the temperature from the beginning of the 60 degrees, up every 10 degrees, increasing the service life of oil will be halved, so the effect of high temperature of lubricating oil is very obvious. 1. 1 paper machine lubricant performance requirements paper mills and rolling mills are similar, so the first characteristic is water and chemical pollution is larger, the pulp to invade the lubrication system. This requires a lubricating oil must have good water performance and anti-rust and anti-corrosion performance. The second is the working temperature is high, the cadres and calender drying cylinder bearing temperature can reach 100 degrees of above. This requires a product with antioxidant and high temperature resistant performance. The third is the heavy work load, to apply to boots and all kinds of roller, gear box, etc. , need oil with anti-wear and extreme pressure performance, but the performance of the job may cause the loss of oxidation resistance, should be adjusted constantly break-in, equilibrium. Fourth equipment precision is high, the work speed is quick, it's the oil bubble resistance and put forward the requirement that the faster the speed, the residence time of oil in the tank more short, the higher demand for oil products. 1. The standardization of the 2 machine industry equipment manufacturers specification papermaking equipment to choose lubricating oil is very important to list the paper machine lubricant shall comply with the relevant specification in detail, such as how many minutes water performance requirements; Crushing performance requirements what level. 2 TCO2 papermaking industry. 1 mill lubrication cost includes the following several categories of lubrication, the following table: most companies buy or now consider the cost of oil, while ignoring the maintenance, repair and energy costs, that is why we put forward the concept of TCO reasons, can help our customers to establish a set of cost plan, you can see the cost of buying oil proportion is very small. 2. Figure 1 2 tco how to bring value for the customer is an implementation of the logic of value chain. The first is the quality of the product; Second, the stand or fall of oil reflects on the device, there will be less wear and accident rate, fuel tank temperature control more and more strong ability of water, etc. ; In the end, from the point of interest, high equipment utilization, lower than planned downtime, lower cost can bring more value for customers. This is a set of complete value chain. 4 in the industry. 0 in the new period, there were new requirements, environmental protection and equipment of Europe and the United States and Japan have the update of lubricating oil. And in the Chinese market, shell also launched a different product. In the hydraulic oil, for example, there are four products are respectively: ( 1) Sea shell strength S1M this is special products for Chinese market, low sulphur phosphorous extreme pressure antiwear formula, good air release properties, 2 kinds of base oil, economic aggressive hydraulic oil. （ 2) Shell lux S2MX mainstream products, well pump protection ability, to adapt to the new high pressure pump, good thermal stability, long service life and suitable for industrial all kinds of hydraulic system. （ 3) Shell to guinness S3M ash-free high-end hydraulic oil products, excellent wear resistance properties at low load and extreme high load can also provide good pump protection, used for overloading, require the use of the long life and special working conditions. （ 4) Shell to guinness S4ME fully synthetic hydraulic oil, TOST over 10000 hours, five times that of ordinary hydraulic oil/hydraulic equipment efficiency of energy saving 4%, suitable for high strength hydraulic application and working condition which requires high temperature or long service life. 3 technical service in order to better serve the industrial customers, shell dealers are formed around the service team, equipped with a filter oil machine, oil filter for paper factory, can prolong the service life of product.
