Sterilization is initiated by one-touch control without the need to remove incubator chamber components before the cycle, including the C[O.sub.2] sensor, UV lamp and fan wheel
. An electronic lock prevents entry during the sterilization process.
Fan system power design has been minimized via optimal matching of interdependent transportation path losses, component air pressure drops, and fan wheel
As a matter of fact, according to the fan wheel
theory (McPherson n.d., see Equation 10.13), the gain in velocity pressure of a fan wheel
is the difference between the outlet and inlet pressures:
Dominated by muscular wheel arches, dynamic air intakes and a 'pulpit-like' cockpit the 918 RSR painted in distinctive "liquid metal chrome blue" has a visible fan wheel
between the ram air intake tubes and a rear spoiler with RS Spyder dimensions.
He managed to hang on and to get back to earth with no bones broken, and we watched helplessly as the tower crashed to earth, bending the big fan wheel
like a pretzel.
"The major sources of noise are going to come from the muffler and also from the fan wheel
. That creates a lot of noise, so this silencer hood goes over the fan wheel
and dampens the noise," explained Jiannas.
Steel tried to correct the problem by manually balancing the fan wheel
shafts during maintenance outages, but the fans would continue to vibrate, typically at 3 to 4 mils, although sometimes at as much as 5 mils, recalled James Meinert, maintenance shift manager.
Features of the system include a high-efficiency cyclone and pleated cartridge filter, neutral vane inlet, a 35-gal dust bin and an aluminum fan wheel
, which Oneida says does not spark.
