Abstract

The invention discloses a Roots blower impeller clearance adjusting tool and an adjusting method. The tool comprises a limiting piece capable of stretching into an air hole of a Roots blower shell, and the length of the limiting piece is larger than the diameter of the air hole; and a limiting part for limiting rotation of a first impeller is arranged at the lower end of the limiting piece, an adjusting screw rod used for abutting against a second impeller and limiting rotation of the second impeller is arranged on the limiting piece, and the limited rotation direction of the second impeller is the same as the limited rotation direction of the first impeller. By the adoption of the tool, the state of the optimal fit clearance between the two impellers can be fixed, then the positions of a gear, an impeller shaft and a bearing are fixed, and the problem that in the prior art, a clearance between two impellers can be changed is solved.

Description

technical field [0001] The invention relates to the technical field of Roots blower, in particular to a tool for adjusting the impeller gap of a Roots blower and an adjusting method. Background technique [0002] The Roots blower is a volumetric blower. The principle of the Roots blower is a rotary compressor that uses two leaf-shaped rotors to move relative to each other in the cylinder to compress and transport 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] At present, after the impellers, bearings and gears are installed in commonly used Roots fans, it is necessary to check the gap between the two impellers with a feeler gauge, and then make fine adjustments to maintain the best fit gap between the impell...
