Abstract
The invention discloses a kind of input pipe for fluid pump or fan, the cross section of the interlude at the centrally located position of described input pipe be non-circular (such as, rectangle, square etc.), the cross section of the linkage section being positioned at two ends is rounded, so that the linkage section of its one end is connected with original input system, the relatively short linkage section of other end length is for connecting the input port of fluid pump or fan. Input pipe in the present invention because being provided with the interlude of one section of noncircular cross section in the position of the input port near fluid pump or fan, just can significantly eliminate and reduce the intensity of fluid media (medium) vortex, and the final stage at immediately impeller is the linkage section that cross section is rounded, can conveniently connect equipment, but owing to it is apart from short, again form the distance of vortex not, it is possible to be effectively improved the problem forming vortex in input pipe.
Description
Technical field
The present invention is about a kind of input pipe, more specifically, about a kind of input pipe that can be effectively improved fluid pump or fan efficiency.
Background technology
Traditional fluid pump or fan is that the impeller that application rotates sucks fluid (such as water or other fluid media (medium)s), and is ejected in one or more diffusion admittance from the blade edge of impeller at high speed by fluid media (medium). Vortex is often formed when fluid media (medium) enters the entrance of fluid pump by input pipe. The formation of this vortex is a natural phenomena in natural world, for instance: the circulation of each ocean or air is a vortex; The motion of each atom or electronics, is also a vortex, and this natural phenomena is difficult to avoid. And the generation of this vortex will consumed energy, reduce fluid pump apparatus service efficiency.
When the pressure of fluid pump or fan porch declines, fluid media (medium) can be formed when entering the entrance of fluid pump or fan by input pipe and be similar to when earth surface produces certain atmospheric condition so that the tornado that produces when air pressure drops to a certain degree and the hurricane formed across the sea or water spout. Namely when the pressure in fluid pump drops to certain value, the fluid media (medium) in input pipe initially forms very big vortex, and this vortex has higher kinetic energy, thus can consume substantial amounts of energy. Additionally, because fluid media (medium) is rotate with a high rotating speed in fluid pump, be equivalent to a gyro rotated. This kind of gyroscopic effect will resist any effort requiring fluid media (medium) to turn to, further consumed energy again.
Summary of the invention
It is an object of the invention to provide a kind of input pipe that can effectively reduce energy expenditure.
In the present invention, the input pipe for fluid pump or fan is L-shaped, the first connection dish in the input port of the pump housing shell being respectively arranged at two ends with for connecting fluid pump or fan and for connecting the second connection dish of external device, L-type connecting tube between the first connection dish and the second connection dish is formed as the first linkage section, interlude and the second linkage section, the cross section of the interlude at centrally located position is non-circular, the cross section being positioned at first linkage section at two ends and the second linkage section is rounded, and described second linkage section length is not limit; Length ratio between described second linkage section, interlude and the first linkage section is 2 to 1 to 0.5.
The non-circular cross section of described interlude is rectangle, square or polygon.
The length-width ratio of described rectangular cross-sectional is 4 to 3,6 to 5 or 5 to 4.
Arc transition between length and the width of described noncircular cross section, the radius of this circular arc is between 1 to 10 centimetre.
Arc transition between described interlude and the linkage section at two ends.
Input pipe in the present invention is owing to arranging the pipeline section of one section of noncircular cross section in the position of impeller in the pump housing or blower housing of fluid pump, it is possible to significantly eliminates and reduces the intensity of fluid media (medium) formation vortex, reduce the consumption of energy. The another final stage at immediately impeller arranges the linkage section that cross section is rounded, owing to the distance of this linkage section is short, not again forms the distance of vortex.

Detailed description of the invention
Below in conjunction with accompanying drawing in the present invention likely among a specific embodiment be described in further detail.
As it is shown in figure 1, the fluid pump 1 of input pipe includes a pump housing shell 10 in the use present invention, the upper cover 11 of pump housing shell 10 is provided with an entrance 12, for connecting the input pipe 2 in the present invention.
It is provided with impeller (not shown) in the inside of pump housing shell 10, is provided with delivery outlet at sidewall simultaneously, is connected to output channel 13 at equipped at outlet port. The pump housing shell 10 that fluid media (medium) enters fluid pump through input pipe 2 is internal, then through the high speed rotating of pump housing shell 10 internal impeller, exports from the output channel 13 of delivery outlet.
As depicted in figs. 1 and 2, input pipe 2 is L-shaped, the first connection dish 20 in pump housing shell 10 input port 12 being respectively arranged at two ends with for connecting fluid pump 1 and for connecting the second connection dish 23 of external device, it it is the connecting tube of L-type between the first connection dish 20 and the second connection dish 23, this connecting tube is the rounded linkage section 21 in cross section for the two sections of input pipes connecting the first connection dish 20 and the second connection dish 23, 24, middle for being used for connecting two linkage sections 21, 24 be the non-circular interlude 22 in cross section, the cross section of interlude is preferably rectangle, and rectangular length-width ratio is 4 to 3, can certainly be other ratios, such as 5 to 4 and 6 to 5, as shown in Figure 3 and Figure 4, arc transition between length and the width of rectangular cross-sectional, the radius of this circular arc is between 1 to 10 centimetre. the cross section of interlude can also be square or polygon, but is not limited to this, as shown in Figure 5.
As shown in Figure 2, length ratio between input pipe linkage section 24, interlude 22 and linkage section 21 is 2 to 1 to 0.5, can also appropriately adjust on this basis, input pipe 2 arranges the interlude 22 of square-section one section relatively short in the position of the pump intake 12 near fluid pump 1, just can significantly eliminate and reduce fluid media (medium) and form the intensity of vortex, reduce the consumption of energy. Separately owing to the final stage linkage section 21 at immediately impeller arranges the connecting tube that cross section is rounded, owing to the distance of this linkage section 21 is short, not again form the distance of vortex. Arc transition between interlude and linkage section.
