Abstract
The utility model relates to a centrifugal pipeline fan which comprises a machine casing, a volute casing, an air inlet and an air outlet. The utility model is characterized in that the upper end of the machine casing is provided with an outer rotary motor with a single surface support; the outer rotary motor is provided with a forward impeller with multiple wings, and the forward impeller with multiple wings matches the volute casing; an inner cavity plate is arranged in the centrifugal pipeline fan and is provided with an impeller air inlet. The utility model has the advantages of simple structure, small size and big pressure coefficient.
Description
The utility model relates to a kind of pipeline fan, particularly a kind of centrifugal pipeline fan.
At present general pipeline fan has axial-flow blower, flow-mixing blower fan etc., though but above-mentioned blower fan or pressure coefficient is low or boundary dimension big and the bellows machine has a centrifugal fan, but the quite complicated casing of a structure is arranged, be very restricted in the use.
The purpose of this utility model provides a kind of simple in structure, centrifugal pipeline fan that volume is little.
The technical solution of the utility model is a kind of centrifugal pipeline fan of design, comprise casing, volute, intake grill, exhaust outlet, it is characterized in that: there is the inner rotary motor of a single face supporting upper end of casing, multiple wing forward direction impeller is arranged on the inner rotary motor, multiple wing forward direction impeller cooperates with volute, one inner cavity plate is arranged in the machine, an impeller intake grill is arranged on the inner cavity plate.
The utility model has the advantages that simple in structure, volume is little, pressure coefficient is big.
Below in conjunction with accompanying drawing the utility model is elaborated,
Accompanying drawing is a schematic representation of the present utility model, comprise casing 1, volute 2, intake grill 3, exhaust outlet 4 among the figure, it is characterized in that: there is the inner rotary motor 5 of a single face supporting upper end of casing 1, multiple wing forward direction impeller 6 is arranged on the inner rotary motor 5, multiple wing forward direction impeller 6 cooperates with volute 2, one inner cavity plate 7 is arranged in the machine, an impeller intake grill 8 is arranged on the inner cavity plate 7.Inner rotary motor 5 drives 6 rotations of multiple wing forward direction impeller during use, and air is sucked by intake grill 3, inner cavity plate 7, is entered in the volute 2 by impeller intake grill 8, is discharged from exhaust outlet 4 by the 6 rotation pressurizations of multiple wing forward direction impeller.
