Problems solved by technology

Because the water flow continuously beats the volute, it not only brings vibration but also noise. The vibrating volute also causes the pump shaft to vibrate, causing the pump shaft to rotate in a vibrating state, which reduces the service life and further brings rotational vibration. noise

Abstract

The invention discloses a noise-reducing and shock-absorbing centrifugal pump, which comprises a pump body, a motor, a pump shaft, an impeller and a guide vane assembly. Located on the pump shaft and in the pump chamber of the pump body, the guide vane assembly surrounds the periphery of the impeller and is fixed on the pump body; there is a column pipe in the pump chamber, and the guide vane assembly is fixed between the inner wall of the pump body and the upper end of the column pipe A buffer cavity is formed between the column tube and the inner wall of the pump chamber; the impeller has a plurality of impeller outlets extending radially along the impeller and a water inlet extending axially along the impeller, and the water inlet communicates with the column tube; the guide The vane assembly has a plurality of guide vane outlets extending radially along the guide vane assembly, one end of the guide vane outlet communicates with the impeller outlet, the other end of the guide vane outlet communicates with the buffer chamber, and the wall of the buffer chamber is provided with a pump Export. The invention can reduce the vibration of the pump shaft and reduce the noise.

Description

technical field [0001] The invention relates to a pump, in particular to a noise reduction and shock absorption centrifugal pump. Background technique [0002] Centrifugal pumps generally include a pump body, a pump shaft pivotally mounted on the pump body, an impeller is installed on the pump shaft, and a volute is provided on the outer cover of the impeller. The water flow sucked in by the impeller will be collected by the volute and then boosted and then ejected from the outlet of the volute. As the water flow continuously beats the volute, it not only brings vibration but also noise. The vibrating volute also makes the pump shaft vibrate, which makes the pump shaft rotate in the state of vibration, which reduces the service life and further brings rotational vibration. noise. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a centrifugal pump with noise reduction and shock abs...
