Description

Online purifying equipment for oil film bearing oil Technical Field The utility model relates to the technical field of oil product purification, in particular to an on-line purification device for oil film bearing oil. Background In the hot rolling production process of a steel mill, a large amount of cooling water is required for cooling a rolling groove, but due to ageing or poor sealing of a sealing element, the cooling water is very easy to infiltrate into a lubricating system box body, so that the moisture content in the oil film bearing oil is greatly increased. At present, under the technological conditions of steel rolling systems at home and abroad, the water inflow problem of an oil film system is difficult to avoid, and on-line dehydration is difficult to carry out, so that the problem is a common problem in the industry. The finishing mill is core equipment of a high-speed line, the cleanliness and the moisture content of lubricating oil directly influence the running stability of the equipment, if the quality of oil products such as moisture and the like does not reach the standard, abnormal abrasion of friction pairs can be caused due to poor lubrication of the equipment, the damage of the rolling mill is accelerated, the maintenance cost of the equipment is increased, the service life of the equipment is prolonged, and even the equipment accident is caused. According to statistics, the service life of equipment bearings can be reduced by about 48% by comparing the lubricating oil containing 0.04% of water with the lubricating oil containing 0.01% of water, and the continuous water pollution of the oil product can cause the emulsification and deterioration of the oil product, so that the hydrolysis of the additive is accelerated, the physicochemical index of the oil product is decayed to be the oil replacement standard, and finally, new oil is required to be purchased continuously, thereby causing huge economic loss. However, the running speed of the rolling mill is high, the difficulty of realizing on-line dehydration is high, and the problem of dehydration is critical. Therefore, on-line dehydration is realized on the premise of ensuring continuous production of equipment, effective control of moisture in oil film bearing oil of a steel rolling production line is ensured, and the method is one of key links of ensuring normal operation of the equipment, prolonging the service life of the equipment and improving the production efficiency. In view of the defects of actual manufacturing and implementation and use of the scheme, the technical problems that the oil film bearing oil is difficult to realize on-line dehydration and difficult to realize on the premise of ensuring continuous production of the equipment are solved by correcting and improving the scheme, and by the assistance of professional knowledge and experience and the on-line purification equipment of the oil film bearing oil after multiparty chocolate and test, so as to break through the pain point of the industry. Disclosure of utility model The utility model aims to provide an online purifying device for oil film bearing oil, which is used for solving the technical problem that online dehydration of the oil film bearing oil is difficult to realize on the premise of ensuring continuous production of the device. The technical scheme of the utility model is realized as follows: The oil film bearing oil online purification equipment comprises a supporting frame, an oil inlet pump, an electromagnetic heater, a coalescing filter group, a separating filter group, a precision filter and a PLC control cabinet are arranged on the supporting frame, the coalescing filter group comprises a plurality of coalescing filters which are regularly arranged, the oil inlet pump is provided with an inlet, the oil inlet pump is communicated with the bottom of the electromagnetic heater, the upper end of the electromagnetic heater is communicated with the upper ends of a plurality of groups of coalescing filter groups, the bottom of the coalescing filter is communicated with the separating filter group (communicated with an upper port pipeline on one side of the two groups of separating filters), an upper port pipeline on the other side of the separating filter group is communicated with an upper end pipeline of the precision filter, and an outlet pipeline is arranged at the bottom of the precision filter.
