 Friday, January 11, 2019, 13:59, Isaac Earle, Safe Module Parking, Development, , , SMP motor selection decision
|
SMP drivetrain design work is currently underway. Alejandro has selected a suitable 1200:1 reducer which will give a vessel rotation speed of 0.21rpm
with a 1725rpm motor (deemed sufficiently close to the SHC rotation speed of 0.17rpm). The reducer however is only rated for 0.33hp, and Allon's
analysis recommended we use a motor of at least 0.4hp |

|
Target hall crane did not work properly after power outage during Christmas time. The only movement could be operated is crane rotation. Power is supplied
crane. The control board on N-S, E-W and up-down movement showed F51 error code which is tripped limit.. All these clues pointed to a PLC control
problem. Don dale was asked for help. He used the crane control PLC program on an old computer in RH control room reset the PLC system. Everything |

|
ITH:MP1 inlet pressure showed 10torr after power outage during holiday. All ITE/W turbo-pumps were tripped because of it. Removed one shielding block
above the vacuum station. Visually checked oil level and condition in pump. oil level is high. oil color is dark. no oil leak . Installed
a local convectron gauge on pump inlet. After pumping down, It shows pump is good. Tightened all KF 25 and 50 clamps on pump inlet side. Reconnected |
