Description
本新型是有關於一種扇葉，特別是指一種水泵之扇葉裝置。The present invention relates to a blade, and more particularly to a blade device for a water pump.
水泵為常見的流體機械，是將機械能轉換為動能，提供流體能量使流體獲得壓力與速度，讓流體持續流通於管路內。水泵通常安裝於鍋爐或是飲水機內之流體管路系統中。參閱圖1與圖2，為現有的水泵1，該水泵1包含一殼體11、一設置於該殼體11內之轉動單元12、一設置於該殼體11內且用以驅動該轉動單元12之驅動單元13，及一設置於該殼體11上之罩蓋14。該轉動單元12包括一設置於該殼體11內之轉軸121，及一設置於該轉軸121上之扇輪122。該扇輪122具有一設置於該轉軸121上之輪轂123，及多個間隔設置於該輪轂123上之扇葉124。該罩蓋14罩覆所述扇葉124且具有一入水口141，及一出水口142。利用該驅動單元13驅動該轉動單元12之轉軸121轉動且帶動該扇輪122之輪轂123轉動並連動所述扇葉124快速旋轉，使得液體(圖未示)可由該罩蓋14之入水口141被吸入該扇輪122，再藉由快速旋轉之扇葉124帶動液體作高速轉動，以產生離心力使液體獲得動能與流動壓 力，最後再由該出水口142排出，達到輸送液體之目的。A water pump is a common fluid machine that converts mechanical energy into kinetic energy, providing fluid energy to obtain pressure and velocity of the fluid, allowing fluid to continue to flow through the pipeline. The pump is usually installed in a fluid piping system in a boiler or water dispenser. Referring to FIG. 1 and FIG. 2 , a conventional water pump 1 includes a housing 11 , a rotating unit 12 disposed in the housing 11 , and a housing 11 disposed therein for driving the rotating unit. The driving unit 13 of 12 and a cover 14 disposed on the casing 11. The rotating unit 12 includes a rotating shaft 121 disposed in the housing 11 and a fan wheel 122 disposed on the rotating shaft 121. The fan wheel 122 has a hub 123 disposed on the rotating shaft 121 and a plurality of blades 124 spaced apart from the hub 123. The cover 14 covers the fan blade 124 and has a water inlet 141 and a water outlet 142. The driving shaft 13 drives the rotating shaft 121 of the rotating unit 12 to rotate and drives the hub 123 of the fan wheel 122 to rotate and rotates the blade 124 to rotate rapidly, so that liquid (not shown) can be inserted into the water inlet 141 of the cover 14. It is sucked into the fan wheel 122, and then the liquid is rotated at a high speed by the rapidly rotating fan blade 124 to generate centrifugal force to obtain kinetic energy and flow pressure of the liquid. The force is finally discharged from the water outlet 142 to achieve the purpose of transporting the liquid.
水泵1產生流量與增壓的過程中往往會受內部結構設計影響，例如：液體輸送過程中與該扇輪122的摩擦損失、渦流損失或是扇葉數目等。一般而言，水泵1要增加流量與壓力，可以增加所述扇葉124之數目。但也因所述扇葉124之數目過多，當該液體由該入水口141流入時，會與所述扇葉124摩擦阻擋而使流量變小，而影響水泵1之流量，無法同時兼具增加水泵1流量與壓力之效能。The process of generating flow and supercharging of the water pump 1 is often affected by the internal structural design, for example, friction loss with the fan wheel 122 during liquid transportation, eddy current loss or the number of blades. In general, the water pump 1 is required to increase the flow rate and pressure to increase the number of the blades 124. However, because the number of the blades 124 is too large, when the liquid flows in from the water inlet 141, it will be frictionally blocked with the blade 124 to reduce the flow rate, thereby affecting the flow rate of the water pump 1, and cannot simultaneously increase. Pump 1 flow and pressure performance.
因此，本新型之目的，即在提供一種兼具提高水泵流量與壓力之效能的扇葉裝置。Therefore, the object of the present invention is to provide a blade device that has the same effect of increasing the flow rate and pressure of the pump.
