High-speed bearings choose oil and gas lubrication to help upgrade equipment

       With the rapid development of the machinery industry and the increase in environmental requirements. The use of high-speed spindle bearings with oil, gas and oil lubrication not only improves the environment and improves the overall performance of the equipment, but also facilitates the upgrading of the equipment. Oil-air lubrication can adapt to the high-speed operation of the electric spindle, which not only ensures reliable lubrication of the bearing, but also suppresses the temperature rise of the bearing. We need to pay attention to the following issues when applying oil and gas lubrication:

      1. Determination of the oil supply amount and oil supply cycle: To achieve high-speed operation of the electric spindle, it is very important to provide the appropriate oil amount to the bearing. The oil consumption of the bearing oil and gas lubrication needs to be calculated according to the bearing size parameters. The high-speed bearing's reasonable lubrication cycle is 3-10min / time. For details, please refer to the recommended value of the bearing supplier. The main purpose of a good oil supply process is to ensure that the bearings are not underlubricated nor overlubricated.

      2. Compressed air quality: In addition to the above-mentioned oil supply quantity and oil supply cycle, the quality of compressed air is a key factor for the good operation of the electric spindle. Compressed air is not only the driving force for transmitting lubricating oil, but also affects the operating life of the bearings. Dust, impurities, and moisture in compressed air are factors that seriously threaten bearing life. Therefore, it is indispensable to provide high-precision air source filtering and drying systems for electric spindle oil and gas lubrication devices.

      3. Routine maintenance management: When the oil and gas lubrication system is applied, leakage of oil and gas transmission pipelines is strictly prohibited. If the leakage occurs, the transportation of lubricants will fail. Therefore, in the operation management of the oil and gas lubrication system, it is necessary to constantly check the pipeline condition and whether the oil flow condition is good. We also need to pay attention to the back pressure of the spindle lubrication channel and cavity. When the back pressure is too high, it will affect the speed of oil and gas transportation. When the back pressure is equal to the oil and gas pressure, oil and gas will not flow, which will cause the lubricant to fail to reach the bearing position. . Therefore, it is important to pay attention to whether the oil flow is good or not in daily inspection management. The selected oil and gas lubricating device should have the function of oil and gas pressure detection and alarm, so that it can issue a fault alarm when the back pressure of the bearing cavity rises, the pipeline leaks and blocks, and ensure the good operation of the electric spindle.
