As people's requirements for the efficiency and accuracy of cnc router continue to increase, more and more cnc router manufacturers are now using vacuum table. The vacuum table is mainly used to draw the air between the plate and the workbench surface through a vacuum pump to form a negative pressure, so that the material is tightly adsorbed on the table.
The vacuum adsorption technology is applied to the woodworking cnc router to greatly improve the work efficiency. Like our company's ATC CNC Router series, they all use a vacuum table and are equipped with two 5.5KW vacuum pumps. For cnc router that use vacuum table, vacuum pumps are required. Today, let's take a look at the maintenance methods of vacuum pumps for cnc router.
1. After the vacuum pump is used for a period of time, the adsorption force will drop. The reason is that the dust particles of the sheet enter the pump cavity with the gas and working liquid, or the impeller is stuck. At this time, the dust particles should be washed away through the washing port at the bottom of the pump cover.
2. In winter, if the cnc router is not used for a long time, the liquid in the vacuum pump should be discharged in time, otherwise the vacuum pump will be damaged in cold weather. The solution is to discharge the gas in the vacuum pump first, and then let the liquid flow out after opening the water outlet of the water tank. However, there will still be residual liquid at this time. At this time, the vacuum pump should be rotated by rotating the fan until no liquid flows out, at this time the vacuum pump can be basically emptied.
3. When the vacuum pump is not running for three weeks or more, the vacuum pump may be corroded. At this time, the liquid in the vacuum pump should be drained according to the first article, and then the anti-corrosion treatment should be carried out. The method is to first anti-corrosion 0.5 liters. The oil is poured into the vacuum pump, and then the vacuum pump is turned on for a short time. If the impeller is stuck after the pump is stopped for a long time due to the use of hard water, the pump cavity should be filled with 10% oxalic acid for about 30 minutes.
4. There are many choices of working fluid in the vacuum pump. If hard water is used as the working fluid of the vacuum pump, the hard water should be softened first, or the vacuum pump should be washed with solvent regularly.
5. The vacuum pump should be regularly lubricated under normal operation. After continuous operation for more than 20,000 hours or more than three years, the waste grease should be removed and new grease should be filled.
Each accessory in the cnc machine has many details that need to be maintained. Only by doing every detail can the cnc machine give full play to its maximum value.
If you encounter other problems in the process of using the cnc router, you can also leave us a message, our staff will reply to you in time, hope it will be helpful to you.
