Location of the thrust bearing
Thread Content
This post was last edited by yxmqh on 2010-7-2 at 17:48. I have a question for everyone: on which side of the compressor are the thrust bearings typically located, and on which side is the turbine?
The turbine is on the high-pressure side, and the centrifuge is on the low-pressure side
Generally, it is on the non-driving side [or the coupling side]; the case of double-output shafts is different, haha.
The turbines are all on the steam inlet side, that is, the high-pressure side, while the compressors are also on the steam inlet side, that is, the low-pressure side.
Reply to 4# ningshandong: Could you explain in more detail why the turbine is on the high-pressure side and the compressor on the low-pressure side?
Because the outlet pressure on the high-pressure side is high, a force acts on the rotor in the direction of the low-pressure side; therefore, to counteract this force, a thrust bearing is installed on the low-pressure side: loveliness:
Reply to 3# Man Tianyun: The thrust bearing of New Bileron’s ammonia compressor 2MCL456 is located at the far end of the coupling; I only saw it yesterday
Reply to 7# yangrou250: Yes, that’s exactly what I meant. There was a typo above; it should be “Under normal circumstances, it is always on the non-driving side [the side of the remote coupling]”. Thanks for the correction!
It’s not certain which side it will be; it depends on the design chosen by the manufacturer
Generally, it is on the opposite side of the dead center of the machine’s casing. The dead center of the turbine casing’s sliding pins is usually on the exhaust side; therefore, the thrust disc is located on the high-pressure side. The same is true for compressors, allowing the thermal expansion of the casing and the rotor to offset each other.
Thank you. I’ve learned from it. Many thanks for your guidance
