Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal water pumps, in particular to a multifunctional centrifugal water pump. Background Art

[0002] A centrifugal water pump is a pumping machine that uses the centrifugal motion of water. It consists of a pump casing, an impeller, a pump shaft, a pump frame, etc. After the centrifugal water pump is started, the rotating impeller drives the water in the pump to rotate at high speed. The water performs centrifugal motion, is thrown outward and is pressed into the outlet pipe. After the water is thrown out, the pressure near the impeller decreases, and a low-pressure area is formed near the shaft. The pressure in this area is much lower than the atmospheric pressure. Under the action of atmospheric pressure, the external water enters the pump through the water inlet pipe. The continuously injected water is thrown out again with the high-speed rotation of the impeller, and is continuously pressed into the outlet pipe. In this way, the impeller is driven by the power machine to rotate continuously at high speed, and the water is continuously pumped into the required place. However, when the water pump is working, the body will vibrate due to the rotation of the impeller and the operation of the motor, which can easily cause the body and the water pipe interface to fall off and loosen, resulting in abnormal water supply. For this reason, we propose a multifunctional centrifugal water pump. Utility Model Content

[0013] The pump body and the motor are fixed to the top of the shock-absorbing assembly at the bottom through a vibration isolation bracket. When the motor runs and drives the pump body to run, the vibration generated by the body is transmitted to the support plate through the vibration isolation bracket. At this time, the support plate vibrates, thereby driving the first spring to vibrate, and then the vibration is transmitted to the first spring for absorption. At this time, the first spring releases the absorbed pressure outward, and further absorbs it through the contraction of the fixed tube and the telescopic column. In addition, a rubber pad is provided on the outer top of the telescopic column to further increase the friction force, ensuring that the absorbed pressure will not act on the body again, thereby ensuring the stability of the body operation. At the same time, after the pump body draws water from the source, it is filtered through the filter element inside the conduit to reduce the sediment in the water body and ensure the quality of the water body.
