Carrying on pulsation principle,the impeller upstream and the downstream
static pressure is nearly equal. When fluid through impeller, limestone slab for sale arkansas
mainly refers to for the fluid energy in the impeller downstream the
useful energy which appears by the kinetic energy form. The fluid flows
out from the impeller is a turbulent flow, may by install after the
impeller downstream guide vane direct inflow connection diffuser, causes
the major part kinetic energy to transform as the static pressure
energy which needs. The axialflow ventilator's movement scope is the
stall line limit. If surpass this limit, first causes the leaf blade
place air current on the necessity to present the local separation. When
in the air blower has the ration turbulent flow,limestone for sale arkansas
on the possibility, namely air draft periodic flowing backwards. works
as system's resistance hairs breadth in the performance diagram of
curves stall line place above, as a result of unstable appearance, then
ventilator impossible in corresponding pressure, current capacity scope
operating point movement. If the machine in the non-stability region
movement, will cause the leaf blade to have the excitation, will cause
the endurance failure.
