Contact type damping device for Roots blower

Abstract

The invention discloses a contact type damping device for a Roots blower, belongs to the field of blower damping devices. According to the contact type damping device for the Roots blower in the scheme, a dual damping system is formed by structures at a damping chamber and an exchange port; when the Roots blower works, vibration generated by working of the Roots blower is firstly transmitted to the damping chamber through an elastic shell and transmitted to damping balls filled into the damping chamber, the vibration is weakened through impact among the multiple damping balls, meanwhile, the damping chamber is pressed to discharge part of hydraulic oil in the damping chamber into a transition chamber through a liquid outlet, and the hydraulic oil enters the damping chamber after breaking through a buffer fiber cluster; and in the process, the hydraulic oil needs to do work on the buffer fiber cluster again, the vibration generated when the Roots blower works is further reduced, the duel damping system is formed, the Roots blower can be suitable for the humid working environment, and normal work of the Roots blower is not prone to being affected.

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.

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
