Abstract
The utility model relates to an internal recycling fan for a cooler of a wind-driven generator. The fan comprises an impeller, a mounting board, an observation window and a motor, and is characterized in that the impeller adopts centrifugal forward circular-arc-shaped blades; different from a frequently-used circular-arc-shaped wheel disc, a front wheel disc is a flat-type wheel disc; under the condition of restricting the size of the impeller, the airflow field is further optimized, so that the flow pressure of the fan is improved; and the fan is mounted in a volute in the cooler of the wind-driven generator. The fan wholly adopts quality carbon structural steel, so that sufficient rigidity and strength are guaranteed and vibration of the fan is reduced; owing to excellent pneumatic performance of the blades of the impeller, and optimized spatial configuration of an air inlet, the impeller and the volute in the cooler of the generator, as well as optimized design of the gap between the diameter of the impeller inlet and the external diameter of the air inlet, the airflow noise of the blow can reach the minimum level; and in addition, the fan has the characteristics of simple structure, convenience for manufacture and installation, stability in running and excellent using effect.
Description
Technical field
What the present utility model related to is a kind of centrifugal fan, particularly is applicable to the wind-driven generator cooler with the cooling centrifugal fan of inner loop, belongs to field of fluid machinery.
Background technique
According to the requirement of wind-driven generator cooler, interior circulation wind blower structure type is comprised of the impeller of forward angle and motor etc., and assembling is in wind-driven generator cooler inner spiral casing.Blower fan is flow 1.4m
3/ s, static pressure is 2500Pa, sound output is less than 103dBA.As according to traditional fan design, existing blower fan is selected the blower fan pattern of impeller+spiral case usually, due to spiral case size and the weight limits of giving in the wind-driven generator cooler, impeller diameter limited size system during design, can not be greater than 466mm, by existing ventilator structure, compressor flow and pressure are difficult to satisfy the requirement of above-mentioned parameter.
Summary of the invention
The purpose of this utility model is to overcome deficiency and the defective of prior art, provides a kind of simple and compact for structure, easy for installation, lightweight, and the wind-driven generator cooler of low noise is with interior circular centrifugal blower fan.
The technical solution of the utility model: a kind of wind-driven generator cooler comprises impeller, mounting plate and fan motor with interior circular centrifugal formula blower fan, it is characterized in that:
Described impeller is forward centrifugal formula blade wheel structure, this impeller is formed by front wheel disc, blade, rear trochal disc and core wheel assembly welding, wherein front wheel disc is different from circular arc type wheel disc commonly used, but adopt straight front wheel disc, blade has adopted centrifugal forward direction circular arc type blade, and the blade quantity in this impeller is 16;
Described mounting plate has one on one side and is convenient to observe the hole that impeller turns to, and the viewing window of the colourless transparent resin glass material that thickness of installation is 5mm on this hole; Fan motor is bolted on mounting plate;
Described should being connected in wind-driven generator cooler inner spiral casing by mounting plate and hex head bolt by interior circular centrifugal formula blower fan; Be that whole blower fan structure adopts eight hex head bolts to be connected in the generator cooler inner spiral casing by mounting plate, this connection has good connection rigidity, vibrates little.
Emphasis of the present utility model is to have adopted centrifugal forward direction circular arc type blade impeller technology, in the situation that impeller size is limited, air velocity distribution is further optimized, improved compressor flow pressure, blower fan has adopted forward centrifugal formula blade wheel structure, blade all adopts the forward direction curved blade, and select rational blade outlet angle, the type blade can reduce resistance, alleviates when starting the impact to blade, make the sound power level of blower fan lower than 103dBA, and vibration velocity is lower than 2.8mm/s.Fan motor is arranged on mounting plate, fix by four each bolts, and mounting plate is bolted in wind in the generator cooler spiral case by eight, and this blower fan all adopts the carbon constructional quality steel material, ensure enough rigidity and intensity, reduced the vibration of blower fan.Adopt forward centrifugal formula impeller, pressure is high, easily manufactured, size is less.In this, circular centrifugal formula blower fan structure is simply compact, easy for installation, lightweight, low noise, due to the excellent aeroperformance of impeller blade, the optimized design of air intake cylinder, impeller, the configuration of generator cooler inner spiral casing spatial optimization and impeller inlet diameter and intake grill crest clearance has guaranteed that the fan airflow noise reaches floor level.
