Description
Technical field
The utility model relates to the blower fan field, particularly centrifugal blower and use the refuse cleaning vehicle of this centrifugal blower.
Background technique
Centrifugal blower is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Centrifugal blower is widely used in ventilation, the dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building; The ventilation of boiler and industrial furnace and air inducing; Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.Centrifugal blower is to be converted to the principle of potential energy according to kinetic energy, utilizes the impeller of High Rotation Speed that gas is accelerated, and then slows down, changes the flow direction, makes kinetic energy convert potential energy (pressure) to.In the one-stage centrifugal blower fan, gas is from axially entering impeller, and gas flow changes over radially when impeller, then enters Diffuser.In Diffuser, gas and changing flow direction cause deceleration, this decelerating effect converts kinetic energy to pressure energy.Increased pressure mainly occurs in impeller, and next occurs in the diffusion process.In Multi-stage centrifugal fan, make air-flow enter next impeller with return channel, produce more high pressure.Working principle and the turbocompressor of centrifugal blower are basic identical, are all because gas flow rate is lower, and pressure changes little, generally do not need to consider the variation of gas specific volume, namely gas are processed as incompressible fluid.centrifugal blower can be made into dextrorotation and left-handed two kinds of patterns. faces from motor one side, impeller turns clockwise, be called the right rotation blower fan, impeller is rotated counterclockwise, being called the anticlockwise blower fan. centrifugal blower essence is a kind of variable-flow constant-voltage equipment. when rotating speed one timing, the pressure-flow theoretical curve of centrifugal blower should be straight line. due to internal losses, the actual characteristic curve is crooked. the pressure that produces in centrifugal blower is subject to the considerable influence of intake temperature or variable density. to a given air inflow, the pressure that produces during the highest intake temperature (air density is minimum) is minimum. for a given pressure versus flow characteristic curve, a power and rating curve are just arranged. when blower during with constant-speed operation, for a given flow, required power raises with the reduction of intake temperature.
Centrifugal blower is the equipment of a complex structure, mainly contains intake grill, air-valve, impeller, casing, motor, exhaust outlet composition.Impeller is arranged in casing, the bottom of casing is provided with the stent support casing, motor is connected with impeller by coupling, the two ends of casing are provided with intake grill and exhaust outlet, because the impeller that is arranged in casing can produce powerful air-flow when rotated, air-flow and casing bump against can produce very large noise.
The problem that exists is, the wind of one side from intake grill inspiration casing, High Rotation Speed in the casing that is sealing under the drive of impeller, the air-flow that produces forms stream swirl in the impeller High Rotation Speed, shock between stream swirl and casing, and the friction between gas and clash into and to produce very large noise in air-flow.When wind was discharged blower fan, wind was discharged from from the exhaust outlet of blower fan on the other hand, produced friction at the edge of the meeting of air-out one's intention as revealed in what one says and casing, produced simultaneously a large amount of noises.
