The design of the ball blast house and the choice of impellerhead is the key introduced.
着重介绍了抛丸室的设计、抛丸器的选型和布置。
2
Theoretical numeral value tallies with fact, which presents the theoretical basis for determining parameters of impellerhead.
理论计算值与实际应用值相符，为抛丸器的参数设计提供了理论依据。
3
To ensure the impellerhead and flow ratings, shaft power should be reduced, to reduce energy consumption, and improve impeller efficiency so as to save energy.
