Abstract
The utility model discloses a glass reinforced plastic blower for a cooling tower, which comprises blades and a hub; and the blades are fixed in the hub through a fixing bolt. The glass reinforced plastic blower is characterized in that each blade adopts a glass reinforced plastic blade, in which a cavity is formed; and each blade adopts a three-dimensional flow pneumatic computation module structure. The glass reinforced plastic blower has the advantages of light weight, convenient assembly, high efficiency, large air flow, low power consumption, low noise, and small vibration and corrosion resistance, can be extensively applied to cooling towers in various forms, and also can effectively solve the problems of poor machining precision, low balancing precision, less possibility of controlling vibration, higher noise and lower efficiency ratio in the traditional internal common aluminium alloy cast blower.
Description
Technical field:
The utility model relates to a kind of blower fan, is specifically related to a kind of big air quantity high efficiency of low noise glass fibre reinforced plastics material cooling tower special fan of optimizing behind the molded lines.
Background technique:
Blower fan 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.
Blower fan is the custom abbreviation of China to gas compression and gas conveying machinery, and usually said blower fan comprises ventilator, blower, and compressor and Roots blower, but do not comprise piston compressor isometric(al) formula blower and compressor.Gas compression and gas conveying machinery are to be the mechanical switch of rotation gas pressure energy and kinetic energy, and the machinery that gas delivery is gone out.
Blower fan is widely used in ventilation, dust discharge and the cooling of factory, mine, tunnel, vehicle, boats and ships and building; The ventilation of boiler and industrial furnace and air inducing; Cooling in the apparatus of air conditioning and the domestic electric appliance and ventilation; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.
Blower fan, in particular for the quality of the blower fan on the cooling tower, for the work of cooling tower, so that the efficient of whole plant produced, very big influence is all arranged.The blower fan that present small-sized cooling tower is extensive use of usefulness is sand-cast aluminium alloy material or aluminium sheet material, also having some is aluminum alloy formed by extrusion and tension, often there is following shortcoming in these blower fans: aluminium alloy casting blower fan machining accuracy is poor, balance quality is low, vibration is not easy control, and noise is higher, efficient is lower.The efficient that aluminum alloy squeezes pull-shaped formula is lower, Heavy Weight, blade profile conversion are not easy, and petiole etc. are located anticorrosion being difficult to and handled.
For this reason, we need a kind of novel used for cooling tower blower fan, solve the problems referred to above.
The model utility content:
The utility model is sand-cast aluminium alloy material or aluminium sheet material at the widely used blower fan of present small-sized cooling tower, also having some is aluminum alloy formed by extrusion and tension, often there is following shortcoming in these blower fans: aluminium alloy casting blower fan machining accuracy is poor, balance quality is low, vibration is not easy control, and noise is higher, efficient is lower.Thereby carried out rational improvement and design, reached the purpose that reduces cost with environmental protection.
In order to achieve the above object, the utility model adopts following technological scheme to realize:
A kind of used for cooling tower fiberglass blower fan comprises blade and wheel hub, and described blade pass is crossed fixing bolt and is fixed among the wheel hub, it is characterized in that, described blade is a fiberglass blade, and inside is provided with cavity.
Described blade adopts three-dimensional flow pneumatic computer airfoil structure.
This model utility, in light weight easy to assembly, the efficient height, air quantity is big, wasted work is few, noise is low, vibrates for a short time, corrosion-resistant, can be widely used in the various forms cooling tower.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the wheel hub of used for cooling tower fiberglass blower fan and the structural representation of U type fixing bolt.
Fig. 2 is the structural representation of the blade of used for cooling tower fiberglass blower fan.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
According to shown in Figure 1, wheel hub 1 on the cooling tower fiberglass blower fan and fixing bolt 3.Because blade adopts embedded Placement, wheel hub 1 effect is each blade of location, and blade 2 is embedded in its groove 4 one by one, makes blade tightly around the rotation of deceleration arbor; Make blower fan form pressure difference up and down during fiberglass blade 2 rotations, thereby make air flow to the air side.The fixing bolt 3 that is used for fixing fiberglass blade 2 adopts the design of U type, and the petiole structure of the fiberglass blade 2 of very fitting is easy for installation, and difficult drop-off is reliable.
According to shown in Figure 2, the blade on the cooling tower fiberglass blower fan adopts glass fibre reinforced plastics material, centre that cavity, in light weight is arranged, and special process is made, and guarantees that each blade center of gravity difference is minimum, and balance is extremely easy, and the intensity height is corrosion-resistant; And application characteristic according to cooling tower, blade adopts three-dimensional flow Pneumatic Calculation model structure, and the cambered surface in each cross section has all obtained optimization, makes that each cross section is the needs that satisfy the real work situation, a difference is more or less all arranged, can guarantee best efficient, make that air quantity is big and noise is low, so compare with traditional aluminium alloy vane, more corrosion-resistant, also dexterousr light, the rotating speed adjustable of blower fan is applicable to the cooling tower that variable working condition is different.
During use, this fiberglass blower fan is in light weight easy to assembly, and the efficient height, air quantity is big, wasted work is few, noise is low, vibrates little, corrosion-resistant.Also, make vane curvature reliable and stable because blade pass is crossed precision die and made; The blower fan higher efficiency to guarantee, according to the molded lines that the characteristic analysis in flow field is made, make that air noise through blade the time is extremely low; Special preparation process is improved the blade balance precision.Glass fibre reinforced plastic material is made more corrosion-resistant, is more suitable for the cooling tower coupling.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
