拆卸前，应标出压缩机机壳、中间机壳和无叶蜗壳的相互位置，以便在安装时能装回原来的位置。拆卸过程中也有很多事项要多注意，下面来看看吧。

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.

松开压缩机壳体、无叶涡壳和中间壳体上的密封件，取下两个壳体。如果这两个物体与中间的壳紧密地排列在一起，可以用橡胶或木槌轻轻拍打外壳。拆卸外壳时，必须注意不要将外壳向轴的方向倾斜。避免与压缩机和涡轮叶片顶部或羊毛外壳相应的内表面发生碰撞。

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.

将涡轮转子轴和叶轮出口六角形凸台固定在工作台副上，识别或制作自锁螺母、涡轮转子轴和压缩机叶轮的动平衡标志。否则，可将带转子的中间壳体从副槽中拆下，压缩机的叶轮部分用沸水浸入锅中，片刻后，叶轮可从转子轴上平稳地脱去。

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.

焦化发电机组压缩机叶轮去除后，握住该涡轮机叶轮，与中间壳体的涡轮机转子轴从在台钳表中删除。在螺纹孔压缩机端的端面光压涡轮机的转子轴，用手除去涡轮转子轴。应谨慎取出转子轴的，螺杆的转子轴不能接触轴承孔和浮子的表面。

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.

用圆嘴钳拆下中缸压缩机端孔卡簧，用两把螺丝拆下压缩机端气封板，从中缸中取出压缩机端挡油板、止推板和隔环。然后从压缩机端的气封板上压出轴封，然后在手指上放两个细铁丝圈，取出轴封上的两个弹性密封圈。

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.

在推力轴承上按下锁板的边缘，用扁螺丝螺丝拧开四个六角形螺栓，然后拆下推力轴承和另一个推力板。

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.

焦化发电机组厂家提醒，需用末端卡箍将弹簧卡环从压缩机端部的轴承孔中拆下，从轴承孔中拆下止推环和浮动轴承，然后从轴承孔在压缩机端的方向上拆下浮动轴承另一端的弹簧卡环。但是，必须小心不要使弹簧卡环磨损轴承孔的表面。

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.

用钳除去中间壳在涡轮端轴承孔卡环，然后取出浮动轴承推力环。重新定向在用尖头钳子在可动轴承卡环的另一端设置在所述涡轮机端，但特别注意不要刮伤轴承孔的表面和所述弹性密封环的除去上述当孔两个卡环。

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.
