Abstract
The present invention relates to a kind of Miniature water-pumping to pump the special pump housing, including a body, one is provided with the body can hold the passage that transmission shaft passes through, and the outside of the passage is equipped with annular flange A and annular flange B successively from the inside to the outside, and leaves certain gap between annular flange A and annular flange B；On the passage heat dissipation channel is additionally provided with along its major axis extending direction.The advantage of the invention is that：Miniature water-pumping of the present invention pumps the special pump housing, the heat dissipation channel along its major axis extending direction is added on the passage passed through for transmission shaft, and then amount of heat caused by transmission process can be made to be distributed along heat dissipation channel, ensure transmission effect, and then improve the service life of suction pump.
Description
Technical field
The invention belongs to water suction pump device, more particularly to a kind of Miniature water-pumping pumps the special pump housing.
Background technology
Suction pump is the effect using atmospheric pressure, and water is promoted to the hydraulic of eminence from lower.It is by water pump, power
Machinery is formed with transmission device.It is widely used in the feedwater of field irrigation, draining and industrial and mining enterprises and cities and towns, draining.
Now widely used suction pump, including pump cover, the pump housing, connecting seat, transition connecting seat, bearing block, bearing, transmission
Axis, transmission device, impeller, water seal, wherein, one is provided with the pump housing can hold the passage that transmission shaft passes through, efficient due to transmission shaft
Rotate, substantial amounts of heat can be caused to be retained among passage, can affect to transmission effect, and then can influence to draw water
The service life of pump.
Therefore, it is to be necessary very much to research and develop a kind of Miniature water-pumping that can improve suction pump service life and pump the special pump housing
's.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of Miniature water-pumping pump that can improve suction pump service life is special
Use the pump housing.
In order to solve the above technical problems, the technical scheme is that：A kind of Miniature water-pumping pumps the special pump housing, its innovative point
It is：Including a body, one is provided with the body can hold the passage that transmission shaft passes through, the outside of the passage from the inside to the outside according to
It is secondary to be equipped with annular flange A and annular flange B, and leave certain gap between annular flange A and annular flange B；Described logical
On road a heat dissipation channel is additionally provided with along its major axis extending direction.
Further, the inner side edge of the annular flange B is evenly distributed with several grooves along its circumferencial direction.
The advantage of the invention is that：
(1) Miniature water-pumping of the present invention pumps the special pump housing, adds on the passage passed through for transmission shaft and extends along its major axis
The heat dissipation channel in direction, and then amount of heat caused by transmission process can be made to be distributed along heat dissipation channel, ensure transmission effect
Fruit, and then improve the service life of suction pump；
(2) Miniature water-pumping of the present invention pumps the special pump housing, wherein, the inner side edge of annular flange B is uniform along its circumferencial direction
Several grooves are distributed with, it is ensured that the smooth clamping of pump cover and the pump housing.
Brief description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the structure diagram that Miniature water-pumping of the present invention pumps the special pump housing.
Embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described scope.
Embodiment
The present embodiment Miniature water-pumping pumps the special pump housing, as shown in Figure 1, being provided with one including a body 1, on the body can hold
The passage 2 that transmission shaft passes through, the outside of the passage 2 are equipped with annular flange 3 and annular flange 4, and annular successively from the inside to the outside
Certain gap is left between flange 3 and annular flange 4；One is additionally provided with the passage 2 along its major axis extending direction to dissipate
The passage of heat 5.
The present embodiment Miniature water-pumping pumps the special pump housing, adds on the passage 2 passed through for transmission shaft and extends along its major axis
The heat dissipation channel 5 in direction, and then amount of heat caused by transmission process can be made to be distributed along heat dissipation channel 5, ensure transmission
Effect, and then improve the service life of suction pump.
In embodiment, in order to ensure the smooth clamping of pump cover and the pump housing, annular flange 4 inner side edge along its circumferencial direction
On be evenly distributed with several grooves.
The basic principle and main feature and advantages of the present invention of the present invention has been shown and described above.The skill of the industry
Art personnel it should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
