Your high speed paper machine of thin oil lubrication system or a square? 2020 - 11 - 08 author: ou chi yong source: pulp technology: the new high-speed paper machine lubricating oil system of tank structure, characteristics and working principle, analysis the advantages and disadvantages. High speed paper machine of thin oil lubrication system is divided into three separate normally closed drainage system: drying cylinder thin oil lubrication system, network department, press section thin oil lubrication system, transmission gear lubricating oil system. Each set of the thin oil lubrication system by the concentrated tank, oil cooler, oil filter, oil pump, inlet pipe, tubing, With mesh) , back to the fuel tank and piping, etc. Currently used for high speed paper machine on the thin oil lubrication system are mainly traditional square tank of lube oil system and the new improved circular tank of lube oil system. Improved circular tank of lube oil system, is by the Finnish Safematic company ( SKF subsidiary) Design of a kind of lubricating oil system, has been applied to more than domestic mill of high speed paper machine. Than the traditional square lubricating oil station greatly reduces the area. The diagram below: cylindrical tank internal structure and working principle of the principle of circular tank containing water, gas, oil from the return pipe after filtering into the tank at the top of the funnel, tangent into the plate at a certain velocity. Because the proportion of water, oil, gas, under the action of centrifugal, tiny air bubbles to the outer limits of the partition cluster, through the diaphragm lateral exhaust duct into the tank at the top of the back row. The diversion of water droplets to partition inside tube agglomeration form large droplets, sink to the bottom of the tank after discharge on a regular basis. After partition clean lubricating oil floating on the top of the tank bottom water impurities, from the side of the lubricating oil tank outlet. Advantages of this kind of tank volume is only 1/3 of the traditional rectangular tank volume, cover an area of an area small, facilitate the maintenance; Inside the fuel tank of lube oil circulation rate is high, more than 90% of the lubricating oil in the loop, and only about 30% of oil in tank in traditional system cycle. For lubrication of papermaking equipment, able to quickly will be key to remove impurities of the water in the lubricating oil and gas, removing impurity rate is high. Prolonging the life of the lubricating oil, fuel tank in addition to its own rapid water function, reduced the water on the emulsification of oil, unlike square tank need additional filter oil machine to remove oil in water. Compared with the traditional oil tank, the tank each little new lubricating oil transshipment, tons of paper low fuel consumption, low operating cost. Disadvantages the round tank of the lubricating oil system in case of large temperature difference is difficult to adjust. As a result of the tank volume is small, equipped with heater heating capacity is low, unable to heat the oil in a short time to the required minimum oil temperature. High degree of automation, the system pressure, pipe flow and oil temperature indicators such as alarm is more, for maintenance personnel to have more cross professional knowledge.
