Dynamic balance noise reducing shock-proof structure of swing piston type vacuum pump

Abstract

The invention discloses a dynamic balance noise reducing shock-proof structure of a swing piston type vacuum pump, comprising a vacuum pump mounting surface rubber gasket, a spring, a vacuum pump mounting bottom rubber gasket and bolts provided with screw rods and blot heads. The dynamic balance noise reducing shock-proof structure of the swing piston type vacuum pump in the invention is provided with the vacuum pump mounting surface rubber gasket, the spring and the vacuum pump mounting bottom rubber gasket and is matched with the bolts, so that the swing piston type vacuum pump is flexibly mounted in a mounting plate on a rack in a matching way, and the shock of the swing piston type vacuum pump is thoroughly stopped from being conducted to the mounting plate when the swing piston type vacuum pump runs to avoid the resonance of the rack.

Description

[0001] technical field [0002] The invention relates to the technical field of noise-absorbing and shock-absorbing structures, in particular to a dynamic balance sound-absorbing and shock-absorbing structure of a rocking piston type vacuum pump. [0003] Background technique [0004] Swing piston vacuum pump has the characteristics of high efficiency and energy saving, safety and environmental protection, stable operation, high reliability, simple structure, completely oil-free, easy maintenance, etc., and is widely used in medical equipment, beauty equipment and small oxygen generating equipment based on the principle of pressure swing adsorption middle. However, the vibration of the swinging piston vacuum pump during work will bring a lot of noise to the whole machine. Therefore, the manufacturers and users of the swinging piston vacuum pump have adopted different noise reduction and shock absorption structures to alleviate the vibration and the vibration caused by the v...

AI Technical Summary

Problems solved by technology

In the installation of this noise-absorbing and shock-absorbing structure, the rocking piston vacuum pump and the mounting plate 13 are in a rigid fit. Although the rubber pad 11 provides a certain buffering effect, the vibration generated by the rocking piston vacuum pump can still pass through the bolts. The screw rod of 15 is transmitted to the mounting plate 13, thereby causing the frame resonance, the noise generated by the frame resonance is amplified in the chassis of the whole machine, and the noise energy is further expanded, and due to the resonance of the frame, the swing piston vacuum pump runs for a long time There is a risk of causing other parts of the whole machine to loosen
