Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a double-suction silent water pump. Background Art

[0002] As an important form of centrifugal pump, double suction pump is widely used in engineering because of its high head and large flow rate. The impeller of this pump type is actually composed of two back-to-back impellers. The water flowing out of the impellers merges into a volute. The double suction pump has the following characteristics: it is equivalent to two single suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same impeller outer diameter; the pump casing is horizontally opened, which is convenient for inspection and maintenance. At the same time, the inlet and outlet of the double suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of the pump and the inlet and outlet pipes; the impeller structure of the double suction pump is symmetrical, there is no axial force, and the operation is relatively stable. The double suction pump runs relatively smoothly, so the noise generated by the pump body is small and relatively quiet. However, the double suction water pump in the prior art generates a large suction force during use, and the inhaled debris is easy to impact the impeller inside the pump body, causing damage to the pump body. In addition, in the process of daily use, the pump body needs to be stopped by a switch when encountering an emergency, which is inefficient. Therefore, it is necessary to improve the prior art.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model adds a filter tube, a filter cover, a cleaning strip and other structures to the water suction pipe of the pump body. When the pump body absorbs water, the debris in the water can be filtered through the filter cover. At the same time, the water flow drives the blades to rotate. During the rotation of the blades, the debris on the outside of the filter cover can be cleaned through the cleaning strip, thereby ensuring the flow area of ​​the filter cover, thereby effectively protecting the impeller inside the pump body.

[0012] 2. The utility model adds structures such as a fixing frame, a square hole tube and a square rod to the base.

The right end of the outer side of the output shaft of the motor 4 is fixedly connected with a rectangular rod 52, and the left end of the input shaft of the pump body 2 is fixedly connected with a short square rod 53. The interior of the fixed frame 51 is slidably connected with a mobile frame 54, and a square hole tube 55 is installed inside the mobile frame 54 through a bearing.

[0022] The specific implementation process of the utility model is as follows: when in use, the motor 4 is started, and the motor 4 drives the rectangular rod 52 to rotate.

During the operation of the pump body 2, suction is generated, and the suction is transmitted to the inside of the filter tube 6 through the water suction pipe 3. The filter tube 6 sucks water into the inside of the filter tube 6 through the extension tube connected to the pipe mouth. After the water passes through the filter cover 10 inside the filter tube 6, it enters the inside of the pump body 2 and is discharged through the drain pipe. When the water flows through the paddle 13, the water flows and drives the paddle 13 to rotate.

When the square hole tube 55 is separated from the short square rod 53, the input shaft of the pump body 2 lacks power and can stop rotating, thereby making the water pump easier to operate.
