Remarks to ambient conditions
The specified permissible ambient temperatures apply to operation of the turbopump at
maximum permissible fore-vacuum pressure or at maximum gas throughput depending
on the cooling method. The turbopump is intrinsically safe by a redundant temperature
monitoring.
●
By reducing the fore-vacuum pressure or gas throughput, the turbopump can be op-
erated at higher ambient temperatures.
●
If the maximum permissible operating temperature of the turbopump is exceeded, the
electronic drive unit reduces drive power first and switches off then, if necessary.
