Abstract
The utility model discloses an efficient balance regulation impeller, which comprises an impeller body and blades arranged on the impeller body, and is characterized in that the number of the blades is 47; the cross section of the blades is arc-shaped; and the arc length of the blades is 1-1.5 times of the length difference between the internal radius and the external radius of the ring-shaped impeller body. The efficient balance regulation impeller has the advantages of reasonable structure, energy saving, low noise and small occupied space, and has benefits of remarkably improving the production efficiency and lowering the maintenance cost of a module.
Description
Technical field
The utility model relates to a kind of impeller, and especially a kind of plastic impeller of the centrifugal blower for vehicle heating and aircondition specifically is a kind of efficient balance adjustment impeller.
Background technique
The multiple wing type centrifugal ventilator is the universal machine that has a large capacity and a wide range, in national economy, occupy certain status, the social demand amount is big, thereby its performance is good and bad extremely important, be applied in more on automobile warm-air air-conditioning and the centrifugal blower at present, general common blower fan adopt the back to impeller or its pressure coefficient of straight line type impeller below 0.5, the pressure under the condition of equating adopts rotating speed high or increase impeller diameter and just can meet the demands, and the profile space is big and shortcoming such as noise height.Multiple wing impeller in the market is made up of 40 circular arc type blades, its pressure coefficient about 1.1, problem such as noise is higher.
The present molding and forming impeller that adopts, it is bigger to raise leveling weighing apparatus difficulty at mould mould is finished after, if mould service time long after, the residual unbalance, of its generation increases, and need carry out very big workload and do and carry out the mould adjustment, increase cost, and difficulty of processing height.
The model utility content
The purpose of this utility model is the technical problem that exists at prior art, a kind of simple in structure, low noise, high efficiency is provided and is convenient to the centrifugal blower fan blade wheel that aequum is regulated.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of efficient balance adjustment impeller comprises impeller body and is arranged on blade on the impeller body that it is characterized in that described blade quantity is 47, the cross section of blade is arc, the arc length of blade be the annular impeller body inside and outside radius length difference 1-1.5 doubly.
Blade is provided with the balance adjustment post.
This impeller is the forward multiple wing type impeller that adopts arc curve blade profile to form.
This impeller blade root portion extends to the center hole direction with level and smooth arc transition.
The beneficial effects of the utility model: the utlity model has rational in infrastructure, energy-saving and low-noise, the little advantage that takes up room, can significantly improve manufacturing efficiency, reduce beneficial effects such as mould maintenance cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, impeller body, 2, blade, 3, the balance adjustment post.
Embodiment
Below in conjunction with specific embodiment the utility model is further described.
As shown in Figure 1.A kind of efficient balance adjustment impeller comprises impeller body 1 and is arranged on blade 2 on the impeller body 1 that described blade 2 quantity are 47, and the cross section of blade 2 is arc, the arc length of blade 2 be annular impeller body 1 inside and outside radius length difference 1-1.5 doubly.
The utility model impeller is the forward multiple wing type impeller that adopts arc curve blade profile to form, the profile space is little, the 1.3-1.5 that pressure coefficient can reach common forward multiple wing impeller doubly, the elongation arc transition design of its low side, effectively avoid the suction port backflow phenomenon, play water conservancy diversion suction port air, reduce the loss of runner mouth pressure, reduce the impeller internal vortex and come off, play very good energy-conservation noise reduction.The utility model impeller blade root portion extends to the center hole direction with level and smooth arc transition.
As solid of rotation, aequum is a very crucial technical order, control amount of unbalance, can reduce vibration, reduce noise, prolong life of product, when mould designs, be provided with balance adjustment post 3 at blade 2, when product the aequum shift phenomenon occurs owing to long-time production, conveniently adjusted.
