A Contact Type Shock Absorbing Device for Roots Blower

Abstract

The invention discloses a contact damping device for a Roots blower, which belongs to the field of blower damping devices, and a contact damping device for a Roots blower. The structure forms a double shock-absorbing system. The vibration generated by the Roots blower will first be transmitted to the shock-absorbing chamber through the elastic shell, and then to the shock-absorbing balls filled in the shock-absorbing chamber. Weaken the above-mentioned vibration, and at the same time, the damping chamber will discharge part of the hydraulic oil in itself through the liquid outlet to the transition chamber when it is compressed, and then break through the buffer fiber clusters to enter the buffer chamber. In the above process, the hydraulic oil needs to be treated again. The buffer fiber clusters perform work to further reduce the vibration generated by the Roots blower when it is working, forming a double shock-absorbing system, which can be applied to a humid working environment and is not easy to affect the normal operation of the Roots blower.

Description

technical field [0001] The invention relates to the field of damping devices for blowers, in particular to a contact damping device for Roots blowers. Background technique [0002] The Roots blower is a volumetric fan, with the end face of the impeller and the front and rear end covers of the fan. The principle is a rotary compressor that uses two leaf-shaped rotors to move relative to each other in the cylinder to compress and deliver gas. This type of blower has a simple structure and is easy to manufacture. It is widely used in aquaculture aeration, sewage treatment aeration, and cement transportation. It is more suitable for gas transportation and pressurization systems in low-pressure situations, and can also be used as a vacuum pump. [0003] Due to the structure and working problems of the Roots blower itself, there will be severe vibrations during the process of the blower compressing the air and discharging it, which makes the Roots blower very easy to generate noi...

AI Technical Summary

Problems solved by technology

[0003] Due to the structure and working problems of the Roots blower itself, there will be severe vibrations during the process of the blower compressing the air and discharging it, which makes the Roots blower very easy to generate noise during the working process. On the other hand, improper shock absorption and noise reduction measures can easily affect the working status of the Roots blower itself, which can easily cause excessive wear and even direct damage, affecting the service life of the Roots blower.

[0004] Most of the existing Roots blower damping devices rely on traditional springs and hydraulic shock absorbers and other damping devices. These shock absorbing devices can effectively relieve the vibration generated during the working process of Roots blowers to a certain extent and reduce the work force. The noise generated can also reduce the excessive wear of the Roots blower during the working process to a certain extent. However, the environment in which the Roots blower is used is usually relatively humid. It is easy to rust in a relatively humid environment, affecting its own shock absorption effect and affecting the normal work of the Roots blower
