    Oil and Gas Lubrication in Bearing of High Speed Rolling Mill

    Author : hani        Time : 2019/09/24

    Application of Oil and Gas Lubrication in Bearing of High Speed Rolling Mill – Equipment Lubrication

    In the transmission system of wire rod finishing rolling (high speed rolling mill), the motor has high speed and high torque. Motor bearings also work at high speeds and loads. For the lubrication of bearings, there are higher requirements. It is necessary to ensure that the lubrication of bearings is fully covered and the heat generated can be discharged in time. The demand for oil consumption of motor bearings is very low. The traditional thin oil lubrication system needs a huge hydraulic circulation system to complete. It not only occupies space but also makes the utilization ratio of the hydraulic system low, and invisibly increases the production cost.

    At present, many systems have adopted centralized oil-gas lubrication. This kind of oil-gas lubrication can meet the needs of bearing lubrication. It not only reduces the loss of lubricant, but also protects bearings by positive pressure formed by compressed gas, so that no external pollution can enter, bearings remain clean, and heat generated by bearings can be discharged in time. But centralized oil-gas lubrication also has its shortcomings. The supply of oil and gas is output by the main unit of the grease plant and then connected to a lubrication point separately. This requires long-distance piping. Oil and gas supply is dispersed, so real-time monitoring of each point cannot be achieved. Oil and gas are transported over long distances and react slowly. Pipeline connection is prone to air leakage and troubleshooting problems. Independent, compact, portable and short-distance oil and gas supply device can provide a reliable guarantee for the lubrication of motor bearings. It also eliminates the dependence on the external oil and gas supply of lubricating grease additives.

    Focus on the research and development of compact oil-gas lubrication device, suitable for the application of oil-gas lubrication occasions, easy to be compatible with all kinds of equipment. It occupies a small space and is easy to install. It provides an independent lubrication unit for the lubrication point.
