What is the purpose of turning the turbine compressor tiles? Why should we turn the tiles?

The shaft diameter is measured with a table, and the crane or operator works closely with it. The accident rate of slipping when turning over tiles is not low. 2. Tile turning is a method of rotating the bearing seat to a visible angle to check alignment and wear. A senior craftsman from our company was severely cut on his hand during the process of turning tiles.

Hahahaha, local dialect, don’t take it too seriously. Just watch him struggle, and the most important thing is to observe his intentions. These people often create some secret words in the circle, such as "a few meters", a few threads, a few threads, etc., which are actually the unit of measurement, mm. If strictly speaking, there is something wrong with the fulcrum he set. This is all for convenience, eliminating the need to remove the upper cover. If a driving sling is used, it is best to select the lifting point close to the volute. Use the guide chain to move the rotor upward slightly, and use a special tool to remove the lower tile. Always pay attention when inspecting and repairing this thing, and no man-made damage can occur. For reference.

one: Turning over tiles has nothing to do with correcting them. 2: The tiles are divided into radial tiles (also called thrust bearings) and axial tiles, also called thrust bearings (Kingsbury, Michel bearings). The tiles are all in a half-section structure.: The upper tiles can be removed directly, but what about the lower tiles? It is pressed by the weight of the rotor and cannot be removed directly, so it can only be removed by turning it up along the shaft. This step is called turning over the tile. Since the surface where the tile and the shaft fit is very smooth, and it is heavy, it is likely to fall down when it is turned up. At this moment, you can easily cut off your fingers, and many people have been injured here. Four: After the lower tile is turned up and removed, the rotor has no support and will fall freely. Turning is strictly prohibited at this time, and it is impossible to straighten it, which will damage the shaft seal.: In the picture on the 3rd floor, a special jig (black) is used to lock the tile base to facilitate turning and alignment. This step is for turning and alignment, not for turning over the tiles.

To turn over the tile, you need to take off the tile under the shaft and check it.

To turn over the bearing bush, you need to remove the lower bush of the bearing bush (the bearing bush is divided into upper bush and lower bush, and the upper bush can be removed directly). However, the main removal action is "turning over". You need to use a "shaft lifter" or driving to lift the rotor by 15 to 30 wires, and then use a small copper hammer to pad it. Use a wooden stick to gently tap the middle surface of the lower tile, so that the lower tile "turns over" in the lower tile pillow with the axis as the center and extends the circular motion of the lower tile pillow. Be careful to remove the probe before turning the tile to prevent the probe wire from being "cut" during the turning process. At the same time, be careful not to "cut your hand". The purpose of turning the tiles is to check whether there are any problems with the lower tiles after turning them out, or to adjust the gap on both sides of the oil seal and air seal of the lower tiles, or even adjust the concentricity through the adjustment gaskets on the lower tiles, which all require turning over the tiles.
