[0024] Please refer to Figs. 1-3 A pry-mounted chassis structure for labyrinth oxygen compressor, comprising chassis 1;

[0025] The main engine chassis 2 is installed on one side of the top of the chassis 1 through fastening piece joint, the motor chassis 3 is installed on the ground foundation on one side of the main engine chassis 2 through anchor bolt 9, the static grounding connector 4 and the bottom plate 5 are welded on one side of the upper part of the chassis 1 in parallel, the compressor body 6 is installed on the main engine chassis 2, forming a compressor unit, the chassis 1 at the bottom of the compressor unit, the ground foundation between the motor chassis 3 is fixed by multi-stage grouting, the motor is installed on the motor chassis 3, the output end of the motor is connected with the compressor body, which is used for driving the rotating operation.

[0026] Before installation, check whether the reserved hole of anchor bolt 9 on the ground foundation and its size meet the requirements of the ground foundation drawing, and then clean the ground foundation. The reserved hole of anchor bolt 9 should be clean, and the ground foundation plane where the compressor unit is placed should be rough and flat without grease. The outer surface of the compressor unit connected with the ground foundation should be cleaned with degreasing agent.

[0027] First grouting: before hoisting, put several temporary shims 7 (thickness about 50-70mm) between the ground foundation and the anchor bolt hole. The compressor unit and the anchor bolt 9 should be hoisted and placed on the temporary shim 9 first, and the main engine chassis 2 plane is checked to be horizontal, and then the first grouting can be carried out.

[0028] The space between the anchor bolt 9 and the corresponding hole of the compressor unit is tightly plugged with a piece of hard paper (which can be removed later), and at this time, the concrete is poured into the anchor bolt hole until the concrete plane is reached.

[0029] Specifically, when adjusting the flatness of the plane, adjustment inclined iron 8 is placed on both sides of the upper part of the anchor bolt 9, which is used to keep the level.

[0030] Among them, the vibrator or round steel can be used to trowel the concrete during the pouring process to remove all the air in the reserved hole.

[0031] Secondary grouting: After the anchor bolt 9 concrete is poured and cured, before secondary grouting, a set of adjusting shims 8 is placed on both sides of the upper part of each anchor bolt 9, and several sets of adjusting shims 8 are placed at the positions where the main engine chassis 2 is prone to bending deformation, to adjust the level of the compressor unit through the adjusting shims 8;
