Fixing device for maintaining centrifugal compressor

Abstract

The invention relates to the field of maintaining fixing, in particular to a fixing device for maintaining a centrifugal compressor. The fixing device comprises a moving base, a rotary driving mechanism, a fixing clamp, a clamp rotating mechanism, an anti-moving mechanism, a secondary hydraulic cylinder and a supporting arm, wherein the rotary driving mechanism is fixedly mounted at the upper end of the moving base; the secondary hydraulic cylinder is fixedly mounted at the top of the rotary driving mechanism; a secondary hydraulic rod is fixedly mounted at an output end of the secondary hydraulic cylinder; the supporting arm is fixedly mounted at the top of the secondary hydraulic rod; an L-shaped structure is formed between the supporting arm and the secondary hydraulic rod; and the fixing clamp is fixedly mounted to the bottom of one end, far away from the secondary hydraulic rod, of the supporting arm through the clamp rotating mechanism. The compressor is clamped and fixed through a primary clamping ring and a secondary clamping ring, thus maintaining is more stable, convenient and rapid, the clamp rotating mechanism makes the clamp suitable for clamping and fixing at different angles, the anti-moving mechanism prevents the base from moving and deviating during clamping and fixing so as to avoid fixing errors, and thus the reliability of the fixing device is improved.

Description

technical field [0001] The invention relates to the field of maintenance and fixing, in particular to a fixing device for maintenance of a centrifugal compressor. Background technique [0002] Centrifugal compressors, also known as turbo compressors, are mainly used to compress gas. The increase of air pressure in centrifugal compressors is achieved by the rotation of the impeller and the expansion of the diffuser. According to the level of the exhaust pressure, the It is divided into three categories: centrifugal fan, whose wind pressure is in the range of 10-15kPa or less; centrifugal blower, whose wind pressure is in the range of 15-350kPa; The pressure and speed of the gas are increased to complete the transportation of the gas. The gas flows radially through the compressor of the impeller. The centrifugal compressor is mainly composed of two parts: the rotor and the stator. The rotor includes the impeller and the shaft. The impeller has blades, balance discs and A part...

AI Technical Summary

Problems solved by technology

[0003] At present, the centrifugal compressor needs to disassemble the equipment and replace some parts during maintenance. During the disassembly process, the force of the disassembly acts on the equipment, which may easily cause the equipment to shake, increase the difficulty of maintenance, and disassemble the centrifugal compressor. Parts that lead to lack of support for the parts connected to it, there are maintenance safety issues
