1. Determination of oil supply and fuel supply cycle: To achieve high-speed operation of electric spindle, it is very important to provide suitable oil quantity for bearings. The fuel consumption of bearing oil and gas lubrication needs to be calculated according to bearing size parameters. The reasonable lubrication cycle of high-speed bearings is 3-10min/time. For details, please refer to the recommended values ​​of the bearing supplier. The main purpose of developing a good oil supply process is to ensure that the bearings are not under-lubricated or lubricated.
2. Compressed air quality: In addition to the above-mentioned oil supply and fuel 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 power to transport the lubricant, but also affects the operating life of the bearing. Dust impurities, moisture, etc. in compressed air are factors that seriously threaten bearing life. Therefore, it is essential to equip the electric spindle oil and gas lubrication device with high-precision air source filtration and drying system.
3. Routine maintenance management: When applying oil and gas lubrication system, it is forbidden to leak oil and gas transmission pipelines. If there is leakage, the transportation of lubricating oil will be faulty. Therefore, in the operation and management of oil and gas lubrication systems, it is necessary to check the pipeline condition and the oil flow condition frequently. We also need to pay attention to the back lubrication of the main shaft lubrication passage and the cavity. When the back pressure is too high, it will affect the speed of oil and gas transmission. When the back pressure is equal to the oil pressure, the oil will not flow, which will cause the lubricant to reach the bearing position. . Therefore, in the daily inspection management, it is necessary to pay attention to whether the oil flow is good. The selected oil and gas lubrication device should have the oil and gas pressure detection and alarm function, which can issue a fault alarm when the back pressure of the bearing cavity rises, the pipeline leaks and is blocked, and ensure the good operation of the electric spindle.
At this time of Chair Hardware should be flat or flip open, chair hardwares include shaft to open chairs or hinge and the chairs shut device such as pin.In order to improve the chairs the wind strength, it is widely used outside the chairs. But hinge must be exposed outside the chairs, the wind and rain erosion resistance of hinge became a problem. Now some of the more than one hundred old buildings in Europe, you can also see 10 times larger than present ordinary hinge of metal hinge, the hinge on the style and ancient European construction is harmonious.Outside the chair hardware of the another question is to prevent the casement of open type in free violently movement under the action of wind, so have the so-called limiter, the limiter in many ways are prone to failure parts.
