Abstract

The invention discloses a vacuum pump with vibration damping and noise reduction functions. The vacuum pump comprises a frame; a rubber layer is disposed at the bottom of the frame; a tempered layer is arranged at the bottom of the rubber layer; springs are fixedly connected to the bottom of an inner cavity of the frame; a base is fixedly connected to the tops of the springs; the bottom of the base extends out of the frame; rolling grooves are formed in the tops of the two sides of the inner cavity of the frame correspondingly; rolling balls are put in inner chambers of the rolling grooves; the ends, far away from the inner chambers of the rolling grooves, of the rolling balls extend to the inner cavity of the frame; a pump body is disposed in the base; the top of the pump body extends out of the base; and an air inlet pipe communicates with the left side of the bottom of the pump body. A noise reduction chamber, a first partition board, a second partition board, a first noise transmission pipe, a second noise transmission pipe and a third noise transmission pipe are adopted for cooperation, and noise enters an inner space of the noise reduction chamber to be transmitted and is weakened constantly in the transmission process till reaching the normal state.

Description

technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to a vacuum pump with functions of shock absorption and noise reduction. Background technique [0002] A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physical and chemical methods to pump air from a pumped container to obtain a vacuum. The existing water circulation vacuum pump relies on a water ring to form a water seal ring to achieve the purpose of vacuum. The vacuum pump The water inlet needs to be connected to the water outlet of the circulating water tank to replenish water, and the equipment connection needs to find a matching interface, which brings trouble to the manufacturer and prolongs the production cycle. For example, the Chinese patent discloses "vacuum pump with water circulation device". The patent number is: CN103939315A, which includes vacuum pump, air inlet, air outlet, water inlet, fixed seat, filter device, liquefact...
