1. Check whether the pump parts are damaged: such as impeller, bearing, pump body, etc. Check the damaged parts and replace them in time to ensure the normal operation of the pump.
2. Check whether the lubricating oil is sufficient: keep the pump lubricating oil sufficient to avoid the phenomenon of rattling caused by insufficient lubrication, should be based on the use of the pump time to regularly replace the lubricating oil, in order to ensure that the pump's normal operation.
3. Clean the inside of the pump: If the air inlet of the pump is not closed or the valve is not working, it will lead to the mixing and accumulation of air, which should be cleaned from time to time.
4. Check whether the pump bolts are loose: after a long time of use, the parts inside the pump (such as intake valve, pressure edge) will be loose, should be disassembled as soon as possible to check the timely compression.
5. Regular maintenance and repair: regular inspection and maintenance of the vacuum pump, regular replacement of lubricating oil, cleaning of the pump debris, timely replacement of damaged parts are important measures to ensure the normal operation of the pump.
In summary, the vacuum pump rattling may be caused by the damage of pump parts, insufficient lubrication, gas into the pump, loose bolts and other reasons. In daily operation, we should regularly check and maintain the vacuum pump, find and solve problems in time to ensure the smooth progress of the experiment.
