Steel rolling altitude oil film bearing lubricating device and system

Abstract

The invention provides a steel rolling altitude oil film bearing lubricating device and system, and relates to the technical field of mechanical equipment. The steel rolling altitude oil film bearinglubricating device comprises an oil tank, a coarse filter and a fine filter. The output end of the oil tank is communicated with an inlet of the coarse filter. An outlet of the coarse filter is communicated with an inlet of the fine filter. After oil liquid output by the oil tank is filtered by the coarse filter, the oil liquid is filtered by the fine filter, so impurity accumulation of the fine filter is reduced, and service life of the finer filter is prolonged. The steel rolling altitude oil film bearing lubricating system comprises the above steel rolling altitude oil film bearing lubricating device, and has the advantage of prolonging the service life of the device.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a lubricating device and system for an oil film bearing of a steel rolling high wire. Background technique [0002] The oil film bearing lubricating device of steel rolling high-speed line is a tie-line oil film bearing, which is in a high-temperature, high-speed, and large water vapor environment. Due to the high-speed rotation of the oil film bearing, the oil film bearing neck will generate negative pressure, which has suction for moisture and impurities in the external environment. If the water seal is damaged or the sealing surface is corroded, it is easy to enter the lubrication system and cause the medium to emulsify. The lubrication system is basically an open system. Unlike the fully closed hydraulic system, the service object is easy to enter water and impurities, and the system medium is generally very viscous. Therefore, the filter equipment configuration ...

AI Technical Summary

Problems solved by technology

[0004] In short, the existing bearing lubricating devices have the following problems: (1) the filter is generally a fine filter, which needs to be replaced frequently due to the deposition of impurities, and the service life is low; (2) the moisture and cleanliness cannot be monitored in time, resulting in The emergence of some follow-up problems; (3) The filter function is relatively single and cannot adapt to different flow rates of oil
