Lubrication System Maintenance for Double Disc Grinding Machines
As a high-precision machining machine, the normal operation of the lubrication system is critical to the performance, life and machining accuracy of the double disc grinding machine. The main function of the lubrication system is to reduce friction, wear and tear, dissipate heat and prevent corrosion, thus ensuring that the equipment maintains stability and reliability over a long period of time.
The importance of the lubrication system is self-evident. In the high-speed grinding process, the moving parts of the equipment generate a lot of friction and heat. If the lubrication is insufficient or the lubrication system fails, it will lead to increased wear of the parts, higher temperatures, and even cause equipment failure. In addition, poor lubrication will also affect the machining accuracy of the workpiece, resulting in dimensional deviation or substandard surface roughness.
Regularly check the quality of lubricant is the first task of lubrication system maintenance. The quality of the lubricant directly affects the lubrication effect. In the process of use, the lubricant will gradually be contaminated or oxidised, leading to a decline in its performance. If the lubricant is found to be deteriorated or contain impurities, it should be replaced promptly. It is equally important to maintain an adequate supply of lubricant. The oil level of the lubricant is an important indicator of the normal operation of the lubrication system. The operator should regularly check the oil level of the tank to ensure that the lubricant is always within the specified range. If the oil level is too low, the lubricant should be replenished in time to avoid wear and tear of the equipment due to insufficient lubrication.
Cleaning the lubrication lines and nozzles is also an important step in maintaining the lubrication system. Pipes and nozzles in the lubrication system are easily blocked by impurities or sludge, affecting the normal delivery of lubricant. For automatic lubrication systems, check the working condition of the distributor to ensure that it distributes the lubricant evenly. Monitoring the pressure of the lubrication system should not be overlooked. The pressure of the lubrication system is an important parameter in determining its operating condition. If the pressure is too low, it may be due to pump failure or line leakage; if the pressure is too high, it may be due to line blockage or excessive resistance at the lubrication point.
Regular replacement of lubricant and filter element is a key measure to ensure the long-term stable operation of the lubrication system. The lubricant will gradually deteriorate during use, and the filter element will also fail due to adsorption of impurities. Generally speaking, it is recommended to replace the lubricant every six months to one year, and replace the filter cartridge at the same time. In addition, checking the lubrication effect of the lubrication point is also an important part of the maintenance work. The ultimate purpose of the lubrication system is to provide sufficient lubricant for each lubrication point of the equipment. For manual lubrication systems, operators should manually refuel the lubrication points on a regular basis in accordance with the requirements of the equipment manual.
In practice, the lubrication system may appear some common problems, lubricant leakage is usually due to the aging of seals or piping joints loose caused by the seals should be replaced in time or tighten the joints. Lubrication system pressure abnormality may be due to oil pump failure, pipeline blockage or lubrication point resistance caused by excessive, need to check the working condition of the oil pump, clean lubrication pipeline, and check the lubrication point lubrication. Insufficient lubrication at the lubrication point may be caused by clogging of the pipeline or distributor failure, you need to clean the pipeline or replace the distributor.
