[0002] Energy-saving vacuum pumps use a pair of gears that mesh with each other to achieve relatively synchronous operation. The driving shaft is connected to the output end of the motor through a coupling. When driving, the gears mesh with each other to form a negative pressure, thereby generating suction to evacuate the container to obtain a vacuum device or equipment.

[0003] When using an energy-saving vacuum pump for vacuuming, the energy-saving vacuum pump itself will inevitably vibrate, and because the base of the energy-saving vacuum pump mostly needs to be installed on a bracket, the vibration generated by the energy-saving vacuum pump will collide with the bracket, causing it to generate noise at the same time, which will affect people's normal rest, study and work.
