Abstract
The utility model relates to a ventilating plant for air-conditioning ventilation system, in particular to a closed inclined flow vane cylinder fan, mainly comprising a closed inclined vane, a motor, a current collector, an internal cylinder, a casing, a guide blade and a diffuser. Because the closed inclined vane is adopted, the utility model has the advantages of improving fan efficiency, generating higher pressure and flow quantity and lowering noise; and because the casing does not need to be made into the shape of a cylinder or a conical cylinder like that of an open inclined vane fan and an axial wheel fan, the casing can be made into the shape of a square cylinder, thereby the utility model has the advantages of convenience in connecting with an air pipe and simpler assembly.
Description
The utility model relates to a kind of ventilation equipment that are used for air conditioner ventilating system, particularly enclosed diagonal impeller tubular blower fan.
The impeller of the blower fan that is used for air conditioner ventilation pipeline system in the past all adopts open type diagonal impeller or axial-flow blower, because open type diagonal impeller and axial-flow blower are not with shroud, its efficient generally is lower than the impeller of band shroud, therefore adopts the blower fan of open type diagonal impeller and axial-flow blower often to produce higher aerodynamic noise and lower efficient.
The purpose of this utility model is to adopt the enclosed diagonal impeller, carry out the blower fan global design according to aerodynamic principle, to provide a kind of flow coefficient, pressure coefficient and efficient higher, noise is lower, compact structure and be convenient to the novel fan that air conditioner ventilating system is installed.
The purpose of this utility model realizes by following technological scheme.Enclosed diagonal impeller tubular blower fan mainly is made up of parts such as enclosed diagonal impeller, motor, inner core, casing, import slip ring, exducer, stator and Diffusers.Impeller is installed on the motor reel, by the direct drives impeller rotation of motor.Motor is fixed on the inner core by support or passes inner core and is fixed on the casing.The axial direction of motor is consistent with the axial direction of casing.Casing is cylindrical shape or square tube shape.The import slip ring is installed on the impeller inlet place, and exducer is installed on the impeller outlet place, and stator is installed between inner core and the casing, and Diffuser is installed on the inner core afterbody.So just constituted enclosed diagonal impeller tubular blower fan.When blower fan turns round, air-flow at first enters impeller by the import slip ring, after the impeller acting, guide to the blower fan air-out direction by the impeller outlet fluid director again, after air-flow enters between the blower fan inner/outer tube, under the effect of stator, reduce rotating in a circumferential direction, to raise the efficiency, under the effect of the Diffuser at inner core rear portion, the further boost pressure of air-flow.
The utility model has produced higher pressure and flow owing to adopted the enclosed diagonal impeller, has also improved efficient, has reduced noise.Simultaneously, owing to needn't casing must be made cylindrical shape or taper barrel, therefore fan casing can be made square tube shape as open type diagonal impeller and axial-flow blower blower fan.Ventilation duct is generally square tubular, and the blower fan of square tube shape casing is convenient to be connected with ventilation duct, makes installation easier, also makes ventiduct system compacter, has saved installing space and installation material.
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a stator section configuration schematic representation.
Impeller [4] is fixed on the axle of motor [8], and motor [8] is fixed on the inner core [6] with support, and inner core [6] is fixed on the casing [5] with stator [7], and the section configuration of stator [7] is a circular arc, has both play a part to connect inner core and casing, also plays guide functions.The inlet of impeller [4] is equipped with import slip ring [1], and the outlet port is equipped with exducer [3], and exducer [3] steering flow moves to the blower fan air-out direction.The rear portion of inner core [6] is equipped with Diffuser [9], and making works off one's feeling vent one's spleen flows to a step boost pressure.
