Specific embodiments

[0020] The present utility model will be further described below in conjunction with the embodiments shown in the drawings:

[0021] As Figures 1 to 5As shown in the figure, there is a special horizontal and vertical high-rise partition pump. The type of this pump is a horizontal pump. When placed horizontally, it is installed on the ground through the fixed seat of the housing of the driving motor 23, the first water outlet housing 1 and the fixed seat on the right side of the water inlet valve seat 8. The water inlet is in the middle of the flange at the bottom of the water inlet valve seat 8. When it is a horizontal pump, it includes a first water outlet housing 1 with a circular cross-section. One end of the first water outlet housing 1 is provided with a number of second water outlet housings 3 and a first diversion housing 4. An outlet interface 5 is connected to the outside of each of the first water outlet housing 1 and the second water outlet housing 3. A threaded groove 51 is provided at the end of the outlet interface 5. After such a setting, the external water pipe can be detachably connected to the outlet interface 5 through the threaded groove 51, which increases the convenience of the user's connection pipeline and brings convenience during use. A diversion impeller 7 is rotatably arranged inside each of the first diversion housings 4. The external driving assembly 2 is connected to the inside of the diversion impeller 7, and the driving assembly 2 can drive the diversion impeller 7 to rotate. A number of first inclined diversion plates 41 are provided inside each of the first diversion housings 4. A number of second inclined diversion plates 71 are provided inside each of the diversion impellers 7. A water inlet valve seat 8 is provided at the top of the first diversion housing 4 at the top. Fixed flanges 81 are provided on the outside of the water inlet valve seat 8 and the outside of the first water outlet housing 1. A fixed pull rod 82 is provided inside between the adjacent upper and lower fixed flanges 81. After such a setting, water first enters from the inlet of the water inlet valve seat 8 and gradually flows towards the inside of the first diversion housing 4. Then the diversion impeller 7 starts to rotate. The water will pass through the second inclined diversion plates 71 and be thrown upwards under the action of centrifugal force into the inside of the first inclined diversion plates 41. Then it will flow from the inside of the first inclined diversion plates 41 into the inside of the second water outlet housing 3 or the first water outlet housing 1. If pipelines are connected to the outside of the first water outlet housing 1 and the second water outlet housing 3, then the water will flow out from the inside of the outlet interface 5.

[0022] In this embodiment, a sealed mounting groove 11 is provided inside the first water outlet housing 1, a mechanical seal assembly 6 is provided inside the sealed mounting groove 11, and the drive assembly 2 is connected to the inside of the mechanical seal assembly 6. Specifically, the mechanical seal assembly 6 includes a dynamic ring boss 61, a static ring boss 62, a metal spring, and a silica gel sealing ring 63. A dynamic ring boss 61 is provided inside the sealed mounting groove 11. One end of the dynamic ring boss 61 is provided with a static ring boss 62 that fits against the bottom of the sealed mounting groove 11. A metal spring in a compressed state is provided between the dynamic ring boss 61 and the static ring boss 62. A silica gel sealing ring 63 is provided in the contact area between the dynamic ring boss 61 and the sealed mounting groove 11, and a silica gel sealing ring 63 is also provided at the junction between the dynamic ring boss 61 and the static ring boss 62. The drive assembly 2 includes a support housing 21, a coupling 22, a drive motor 23, and a drive rotating shaft 24. A support housing 21 is provided on one side of the first water outlet housing 1. A coupling 22 is provided inside the support housing 21. A drive motor 23 is provided on one side of the support housing 21. The rotating shaft of the drive motor 23 is connected to one end of the coupling 22. The other end of the coupling 22 is provided with a drive rotating shaft 24. The drive rotating shaft 24 is connected to the dynamic ring boss 61 and each flow guide impeller 7. After such a setting, the rotating shaft of the drive motor 23 can drive the coupling 22, the coupling 22 can drive the drive rotating shaft 24 to rotate. During the rotation of the drive rotating shaft 24, each flow guide impeller 7 will be driven. And during the rotation of the drive rotating shaft 24, due to being squeezed by the metal spring, the static ring boss 62 tightly fits against the bottom of the sealed mounting groove 11 and is in a relatively stationary state, preventing water from flowing out through the gap between the static ring boss 62 and the bottom of the sealed mounting groove 11. The relative dynamic ring boss 61 will rotate. During the rotation of the dynamic ring boss 61, it uses the silica gel sealing ring 63 to prevent water from leaking out from the side wall between the dynamic ring boss 61 and the sealed mounting groove 11, or water from leaking out from the junction between the dynamic ring boss 61 and the static ring boss 62, thereby achieving the sealing effect.

[0023] As Figure 6 shown, the type of this pump is a vertical pump. Different from a horizontal pump, the flange at the bottom of the water inlet valve seat 8 cannot intake water. This is because the flange mainly plays a fixing role, and its water intake is through the pipeline on the right side. The fixing seat of the outer shell of the drive motor 23 is also cancelled, and other structures are the same as those of a horizontal pump.

[0024] Working principle and usage method of the present utility model:

[0025] For a horizontal pump, first, external water is connected to the inside of the water inlet valve seat 8. That is to say, water enters from the inlet of the water inlet valve seat 8 and gradually flows towards the inside of the first guide housing 4. Then, the rotating shaft of the driving motor 23 can drive the coupling 22, and the coupling 22 can drive the driving rotating shaft 24 to rotate. During the rotation of the driving rotating shaft 24, each guide impeller 7 will be driven. And during the rotation of the driving rotating shaft 24, the stationary ring boss 62 is tightly pressed against the bottom of the sealing installation groove 11 due to the extrusion of the metal spring, and is in a relatively static state to prevent water from flowing out through the gap between the stationary ring boss 62 and the bottom of the sealing installation groove 11. The relative moving ring boss 61 will rotate. During the rotation of the moving ring boss 61, the silicone rubber sealing ring 63 is used to prevent water from seeping out from the side wall between the moving ring boss 61 and the sealing installation groove 11, or from the connection between the moving ring boss 61 and the stationary ring boss 62. At this time, the moving ring boss 61 and the guide impeller 7 rotate together. Water will pass through the second inclined guide plate 71 and be thrown upwards into the first inclined guide plate 41 under the action of centrifugal force, and then flow from the inside of the first inclined guide plate 41 into the inside of the second water outlet housing 3 or the first water outlet housing 1. If pipelines are connected to the outside of the first water outlet housing 1 and the second water outlet housing 3, then water will flow out from the inside of the water outlet interface 5. For a vertical pump, only the water inlet end is on the right pipeline of the water inlet valve seat 8.

[0026] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
