拆卸前，應(yīng)標(biāo)出壓縮機(jī)機(jī)殼、中間機(jī)殼和無葉蝸殼的相互位置，以便在安裝時能裝回原來的位置。拆卸過程中也有很多事項(xiàng)要多注意，下面來看看吧。

Before disassembly, the mutual positions of compressor casing, intermediate casing and leafless volute shall be marked so that they can be installed back to their original positions during installation. There are also many things to pay attention to during disassembly. Let's have a look.

松開壓縮機(jī)殼體、無葉渦殼和中間殼體上的密封件，取下兩個殼體。如果這兩個物體與中間的殼緊密地排列在一起，可以用橡膠或木槌輕輕拍打外殼。拆卸外殼時，必須注意不要將外殼向軸的方向傾斜。避免與壓縮機(jī)和渦輪葉片頂部或羊毛外殼相應(yīng)的內(nèi)表面發(fā)生碰撞。

Loosen the seals on the compressor housing, vaneless volute and intermediate housing and remove the two housings. If the two objects are closely aligned with the middle shell, gently tap the shell with a rubber or wooden mallet. When removing the housing, care must be taken not to tilt the housing towards the shaft. Avoid collision with the top of the compressor and turbine blades or the corresponding inner surface of the wool housing.

將渦輪轉(zhuǎn)子軸和葉輪出口六角形凸臺固定在工作臺副上，識別或制作自鎖螺母、渦輪轉(zhuǎn)子軸和壓縮機(jī)葉輪的動平衡標(biāo)志。否則，可將帶轉(zhuǎn)子的中間殼體從副槽中拆下，壓縮機(jī)的葉輪部分用沸水浸入鍋中，片刻后，葉輪可從轉(zhuǎn)子軸上平穩(wěn)地脫去。

Fix the turbine rotor shaft and the hexagonal boss at the impeller outlet on the workbench pair, and identify or make the self-locking nut, the dynamic balance mark of the turbine rotor shaft and the compressor impeller. Otherwise, the intermediate housing with rotor can be removed from the auxiliary groove, and the impeller part of the compressor can be immersed in the pot with boiling water. After a while, the impeller can be smoothly removed from the rotor shaft.

焦化發(fā)電機(jī)組壓縮機(jī)葉輪去除后，握住該渦輪機(jī)葉輪，與中間殼體的渦輪機(jī)轉(zhuǎn)子軸從在臺鉗表中刪除。在螺紋孔壓縮機(jī)端的端面光壓渦輪機(jī)的轉(zhuǎn)子軸，用手除去渦輪轉(zhuǎn)子軸。應(yīng)謹(jǐn)慎取出轉(zhuǎn)子軸的，螺桿的轉(zhuǎn)子軸不能接觸軸承孔和浮子的表面。

After the compressor impeller of the coking generator set is removed, hold the turbine impeller and remove the turbine rotor shaft with the intermediate housing from the table of vises. Press the rotor shaft of the turbine on the end face of the compressor end of the threaded center hole, and remove the turbine rotor shaft by hand. Take out the rotor shaft carefully. The rotor shaft of the screw shall not contact the bearing hole and the surface of the float.

用圓嘴鉗拆下中缸壓縮機(jī)端孔卡簧，用兩把螺絲拆下壓縮機(jī)端氣封板，從中缸中取出壓縮機(jī)端擋油板、止推板和隔環(huán)。然后從壓縮機(jī)端的氣封板上壓出軸封，然后在手指上放兩個細(xì)鐵絲圈，取出軸封上的兩個彈性密封圈。

Remove the circlip at the compressor end of the intermediate cylinder with round nose pliers, remove the air seal plate at the compressor end with two screws, and take out the oil baffle, thrust plate and spacer ring at the compressor end from the intermediate cylinder. Then press out the shaft seal from the air seal plate at the compressor end, put two thin wire rings on your fingers, and take out the two elastic sealing rings on the shaft seal.

在推力軸承上按下鎖板的邊緣，用扁螺絲螺絲擰開四個六角形螺栓，然后拆下推力軸承和另一個推力板。

Press the edge of the locking plate on the thrust bearing, unscrew the four hexagon bolts with flat screws, and then remove the thrust bearing and the other thrust plate.

焦化發(fā)電機(jī)組廠家提醒，需用末端卡箍將彈簧卡環(huán)從壓縮機(jī)端部的軸承孔中拆下，從軸承孔中拆下止推環(huán)和浮動軸承，然后從軸承孔在壓縮機(jī)端的方向上拆下浮動軸承另一端的彈簧卡環(huán)。但是，必須小心不要使彈簧卡環(huán)磨損軸承孔的表面。

The coking generator set manufacturer reminds that it is necessary to remove the spring snap ring from the bearing hole at the end of the compressor with the end clamp, remove the thrust ring and floating bearing from the bearing hole, and then remove the spring snap ring at the other end of the floating bearing from the bearing hole in the direction of the compressor end. However, care must be taken not to allow the snap ring to wear the surface of the bearing bore.

用鉗除去中間殼在渦輪端軸承孔卡環(huán)，然后取出浮動軸承推力環(huán)。重新定向在用尖頭鉗子在可動軸承卡環(huán)的另一端設(shè)置在所述渦輪機(jī)端，但特別注意不要刮傷軸承孔的表面和所述彈性密封環(huán)的除去上述當(dāng)孔兩個卡環(huán)。

Remove the snap ring at the turbine end bearing hole of the intermediate housing with pliers, and then take out the floating bearing thrust ring. The other end of the movable bearing snap ring is set at the turbine end with a pointed pliers, but special attention shall be paid not to scratch the surface of the bearing hole and remove the two snap rings of the elastic sealing ring.
