Some precautions when using the vacuum pump in the engraving machine

Some of the engraving machines of the original force machine are equipped with vacuum pumps, such as woodworking engraving machines and plate production lines that can often be seen. The following engraving machine manufacturers Guangzhou Sanwei Electromechanical Xiaobian share

    1. Disposal method for long-term pump stop. If the vacuum pump is finished for 4 weeks, you should exhaust the pump according to item 3 afterwards, and then finish the anti-corrosion treatment, that is, use 1/2 liter of anti-corrosion oil from the suction port or exhaust. Pour the vacuum pump into the mouth and end the short-term operation. If the impeller is stuck after long-term pump stop due to the application of hard water, the pump chamber should be filled with 10% oxalic acid for about 30 minutes.
    2. If hard water is used as the liquid, the hard water must be hardened, or the solvent should be flushed with the solvent.
    3. Smooth, under the premise of abnormal events, when applying 50Hz motor: After running for 20,000 hours or up to three years, the waste grease and its contents in the bearing and accessory space should be eliminated and filled with new grease. The grease that protrudes should account for 50% of the bearing's free space and 65% of the bearing cap space.
If the premise is unusually inferior, the response of the smoothing fat exchange cycle is prolonged.
    4. When the exhaust air is emptied, close the water outlet of the water tank to allow the liquid to flow out. The transition vacuum pump is migrated by hand transfer of the transition fan until no liquid flows out.
    The inclined pump is 45 degrees and the vacuum pump can be drained at all. Even if the vacuum pump is stopped for a long time or in a cold weather, the pump will not be destroyed.
    5. In order to avoid the impeller, the pump body is worn or the impeller is stuck, the dust particles entering the pump chamber with the gas and the liquid should be washed away through the flushing port at the bottom of the pump cover.
    I hope that our customers will pay attention to the application process.
