Abstract
The utility model discloses a miniwatt synchronous-generator fan including fan-supporting disk faces, a shaft hole, fan negative-pressure-resistance disk faces and blades. The blades are vertically and evenly arranged on the outer circumferential surface of one of the fan-supporting disk face. The fan negative-pressure-resistance disk faces are circular-ring shaped and are arranged at the other side of the blades relative to the fan-supporting disk faces. The central axles of the fan negative-pressure-resistance disk faces and the fan-supporting disk faces coincide. The shaft hole is arranged at the center of the fan-supporting disk faces. The miniwatt synchronous-generator fan increases air circulation amount per time unit in the miniwatt synchronous generator and improves a heat-radiation capability of the generator and reduces effects of drop of generating voltage and output power brought by heating.
Description
Technical field
The utility model belongs to technical field of generators, relates in particular to small-power synchronous generator fan part.
Background technology
The small-power synchronous generator is a kind of small power generation equipment that gasoline engine or diesel engine be power of take.It is lightweight, volume is little, conveniently moving, can long time continuous working, be widely used in communicating by letter, dig up mine, build the road, the field such as forest zone, farmland, irrigation and drainage, field construction and defence engineering, be specially adapted to the environment that utility grid can not be transported to.In addition, the small-power synchronous generator can be used as emergency standby power, once have a power failure, can provide rapidly stable AC power.
At present, general small-power synchronous generator generally adopts the motor radiating structure based on centrifugal fan.This structure fan blade is concentrated and is fixed on a card, by axis hole, with rotating shaft, is connected.During generator work, fan rotates to form air-flow with motor shaft, and the heat produced in the generator course of work is discharged.The advantages such as that this traditional fan has is simple in structure, easy making.But, along with the growth of generator operating time, it is limited in one's ability that this fan structure is controlled the motor internal temperature rise.The rising of temperature will affect the generating output voltage stability, and destroy the electrical machine insulation performance.Therefore, existing small-power synchronous generator fan structure has seriously limited the maximum power that generator can be exported.
Summary of the invention
Goal of the invention: for problem and the defect of above-mentioned existence, the utility model provides the Power generator fan that can produce more rate of air circulation in a kind of unit interval structure.
Technical scheme: to achieve the above object of the invention, the utility model is by the following technical solutions: a kind of small-power synchronous generator fan, comprise that fan supports card, axis hole, the anti-negative pressure card of fan and blade, described blade Vertical Uniform is located on the outer circumference surface of fan support card; The anti-negative pressure card of described fan is circular, with respect to fan, supports the opposite side that card is located at blade, and the central axes of the anti-negative pressure card of fan and fan support card; Described axis hole is located at the center that fan supports card.
As preferably, the internal diameter of the anti-negative pressure card of described fan is identical with the external diameter of fan support card.
As preferably, described blade is pressed the radial direction that fan supports card and is arranged.
As preferably, be provided with the aluminum metal insert in described axis hole.
Beneficial effect: compared with prior art, the utlity model has following advantage: strengthened the rate of air circulation in the small-power synchronous generator internal unit time, improve the motor radiating ability, reduced the generating voltage and the power output decline impact that are brought by heating.
The accompanying drawing explanation
The structural representation that Fig. 1 is fan described in the utility model;
The Facad structure schematic diagram that Fig. 2 is fan described in the utility model;
The cross section structure schematic diagram that Fig. 3 is fan described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
The small-power synchronous generator fan that the utility model provides as shown in Figure 1, 2, 3.Fan mainly comprises following components: 1. fan supports card 1,2. axis hole 2, the 3. anti-negative pressure card 3 of fan, 4. fan blade 4.
Wherein, it is 150mm that fan supports card 1 diameter, and central authorities are provided with axis hole 2.Generator shaft through fan, drives the fan rotation by axis hole 2 during work.3. the anti-negative pressure card of fan is the annulus of external diameter 165mm, internal diameter 150mm, and it is concentric circles with supporting card, and in the time of can effectively suppressing the fan rotation, blade 4 produces and hinders the negative pressure that inner air is discharged.Between anti-negative pressure card and support card, by 12 vertically arranged fan blade 4 of evenly arranging, connect.All blades 4 are arranged according to the card radial direction.
Generator shaft through fan, drives the fan rotation by axis hole 2 during work.During fan work, the generator hot-air forms along the axial quick flow of motor under the fan effect, and generators are discharged in blade 4 spaces through between anti-negative pressure card and support card, and the air-flow running as shown in Figure 1.
The said fans each several part all adopts the high-temperature resistance plastice material.For ensureing that fan can stable operation under generator works long hours state, add the aluminum metal insert in fan axis hole 2, reduce the fan expanded by heating impact caused due to temperature rise, avoid the loosening risk of fan caused because of expansion.
