Abstract
The utility model relates to a pump, in particular to a diaphragm pump low in noise and small in flow delay. The diaphragm pump comprises a base and a motor fixedly installed on the lower portion of the base. The shaft end of the motor stretches into the base and provided with an eccentric wheel, a connecting shaft is arranged on the eccentric wheel, and the included angle of alpha degrees is formed between the axis of the connecting shaft and the horizontal plane. A connector is connected with the connecting shaft in an inserted mode, and a bearing connected with the connecting shaft in a matching and inserted mode is arranged in the connector. The appearance of the diaphragm pump is changed to a triangle from an original square, so the diaphragm pump is smaller, more exquisite and compacter in structure, cost is greatly saved, the angle between the connecting shaft and the horizontal plane is adjusted, the working condition of the connector is more reasonable, the amplitude of swinging is increased, the bearing is increased to enable the connector to operate more stably, and noise is reduced. Inner cavities of the diaphragm pump are changed into three in number, but flow cannot change. The service life of products is substantially prolonged, the noise is low, and the flow decay is small.
Description
Technical field
The utility model relates to a kind of pump, refers in particular to a kind of noise little, the diaphragm pump that flux depression is little.
Background technique
existing diaphragm pump is in the process of using, the eccentric wheel and the connector that are arranged in diaphragm pump can produce larger noise in the process of work, because directly pegging graft with the coupling shaft on being arranged on eccentric wheel, existing connector coordinates, in eccentric rotation process, coupling shaft and eccentric wheel produce friction on the one hand, thereby reduced the working life of connector, if connector damages, just will directly cause scrapping of diaphragm pump, on the other hand, owing to being dry friction between coupling shaft and diaphragm pump, therefore, can produce larger noise in the course of the work, surrounding environment is caused noise pollution.
In addition, existing diaphragm pump generally has four inner chambers, thereby has caused the volume of diaphragm pump larger, from simple reduction size, perhaps reduce the quantity of inner chamber, will cause diaphragm pump in use water flow change, and then be not suitable for original working environment.
The model utility content
The technical problem that one, will solve
The purpose of this utility model is for the existing the problems referred to above of prior art, and the spy provides a kind of structure small and exquisite, compact, has the diaphragm pump in higher working life.
Two, technological scheme
For solving the problems of the technologies described above, the utility model diaphragm pump, wherein, include base and be fixedly mounted on the motor of base bottom, the axle head of said motor extend in base, and the axle head of said motor arranges an eccentric wheel, is provided with axis on above-mentioned eccentric wheel and becomes the coupling shaft of α ° with horizontal plane angle, the a connector of pegging graft on this coupling shaft arranges one and coordinates the bearing of pegging graft with above-mentioned coupling shaft in this connector.
As optimization, the span of above-mentioned α ° is 78 °～83 °.
As optimization, the inner chamber of above-mentioned diaphragm pump is three.
Three, the beneficial effects of the utility model
Change the profile of diaphragm pump into triangle from original square, make structure smaller and more exquisite, compactness has also been saved cost greatly, has adjusted the angle between coupling shaft and horizontal plane, thereby make the working state of connector more reasonable, increase the amplitude that swings, increase bearing and make the connector motion more stable, thereby reduce noise, change the inner chamber of diaphragm pump into three, flow can not change; Significantly the life-span of improving product, noise is low, flux depression is little.
Description of drawings
Fig. 1 is the sectional drawing of the utility model diaphragm pump.
In figure, 1 is base, and 2 is motor, and 3 is eccentric wheel, and 4 is coupling shaft, and 5 is connector, and 6 is bearing.
Embodiment
Below in conjunction with accompanying drawing, the utility model diaphragm pump is described further:
Mode of execution one: as shown in Figure 1, the utility model diaphragm pump, wherein, include base 1 and be fixedly mounted on the motor 2 of base 1 bottom, the axle head of said motor 2 extend in base 1, the axle head of said motor 2 arranges an eccentric wheel 3, be provided with axis becomes α ° with horizontal plane angle coupling shaft 4 on above-mentioned eccentric wheel 3, above-mentioned α °=80 °, adjust the angle between coupling shaft 4 and horizontal plane, thereby made the working state of connector 5 more reasonable, increased the amplitude that swings, increase bearing 6 and make connector 5 motions more stable, thereby reduce noise; Grafting a connector 5 on this coupling shaft 4, this connector 5 is interior to be arranged one and coordinates the bearing 6 of pegging graft with above-mentioned coupling shaft 4; The inner chamber of above-mentioned diaphragm pump is three, changes the inner chamber of diaphragm pump into three, and flow can not change; Significantly the life-span of improving product, noise is low, flux depression is little.The profile of above-mentioned diaphragm pump is triangle, makes structure smaller and more exquisite, and compactness has also been saved cost greatly.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
