Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pumps, in particular to a high-efficiency and stable centrifugal pump. Background Art

[0002] A centrifugal pump is a pump that transports liquids by the centrifugal force generated by the rotation of the impeller. A centrifugal pump works by using the centrifugal motion of water caused by the rotation of the impeller. Before starting the water pump, the pump casing and the suction pipe must be filled with water, and then the motor is started so that the pump shaft drives the impeller and water to rotate at high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows into the water pressure pipeline of the water pump through the flow channel of the volute pump casing.

[0003] Traditional centrifugal pumps generally directly connect the external pipe to its water inlet and outlet to achieve the purpose of extracting liquid. However, the centrifugal pump will vibrate during use. The external pipe is directly connected to the water inlet and outlet of the centrifugal pump. During the vibration of the centrifugal pump, the connection between the external pipe and the centrifugal pump will also vibrate, which will cause water seepage at the connection between the external pipe and the centrifugal pump, affecting the stability of the centrifugal pump.

The ports of the external pipe 10 and the hose 8 are placed on the mounting frame 9, and then the screw 12 is rotated. The screw 12 drives the movable frame 11 to move, and the flange of the port of the external pipe 10 and the flange of the port of the hose 8 are squeezed together by the movable frame 11 to achieve communication. At this time, since the mounting frame 9 is directly fixed on the base 2, the vibration of the centrifugal pump is offset by the first spring 6 and the shock absorber, and the base 2 will not vibrate, thereby keeping the mounting frame 9 stable. Although the vibration of the centrifugal pump can be transmitted to the hose 8, the hose 8 can be deformed and bent, so the vibration will not be transmitted to the mounting frame 9 and the interface between the external pipe 10 and the hose 8, thereby enhancing the stability of the centrifugal pump during use and reducing the water seepage at the connection due to vibration.

[0027] Furthermore, the top of the movable frame 11 and the tops of both ends of the mounting frame 9 are both configured as a "U"-shaped structure so that the external pipe 10 and the hose 8 can be prevented from being on the surface of the movable frame 11 and the mounting frame 9.

When it is necessary to When the screw 12 rotates, pressure can be applied to the connecting rod 16 while holding the handle, so that the connecting rod 16 compresses the second spring 15, and the connecting rod 16 will drive the limiting frame to move, so that the limiting teeth on the limiting frame are disengaged from the limiting tooth grooves on the fixed frame 13, so that the screw 12 can be directly rotated, which is convenient for operation. By setting the rubber pad 3, the friction force can be increased after the base 2 is placed, and the stability of the centrifugal pump body 1 during use is further enhanced. By setting the pull rod 4, when it is necessary to move the whole, the pull rod 4 can be pulled out, and then the entire base 2 can be tilted, and the roller 7 can be used to move it.
