Rectifying booster water pump

Abstract

The invention provides a rectifying booster water pump. The rectifying booster water pump comprises a pump shell and an inlet pipe, and an accommodating cavity is formed in the pump shell. The accommodating cavity is internally provided with a pump machine, and a pump motor is connected with the pump machine for providing kinetic energy for the pump machine, wherein the output end of the motor isconnected to a drive shaft. One end of the drive shaft extends out of the pump shell, and an impeller is arranged at the other end of the drive shaft, wherein the impeller rotates along with the rotation of the drive shaft. The inlet pipe is internally provided with an inlet rectification energy-saving device, and a rectifying shell includes a first shell and a second shell, wherein the first shell and the second shell are formed through a rectifying passage. The first shell and the second shell both have a trapezoidal cross section, and an inner cavity of the rectifying passage is a large regular hexagon composed of a plurality of small regular hexagons. After water in the rectifying booster water pump passes through the rectification device, the loss of pressure is not increased, the energy for forming a vortex is saved, and the vibration noise of the water pump is lower.

Description

technical field [0001] The invention relates to the field of water pumps, in particular to a rectifying booster water pump. Background technique [0002] The water pump is composed of a pump chamber, impeller, motor, inlet and outlet pipes, etc. The motor rotates after being energized to drive the impeller in the pump chamber to rotate, and the pipeline liquid enters the pump chamber through the pump inlet, and then the rotating impeller increases power and then flows out from the outlet. flow out. Therefore, the water pump has the function of liquid delivery to meet the flow requirements of the pipeline. [0003] At present, water pumps are widely used in pipelines. However, since the water pumps are made of cast iron or steel, the motor and the impeller will vibrate violently during operation. The vibration of the water pump and the isolation vibration will be transmitted to other surrounding components, resulting in vibration and resonance of the pipeline and noise poll...

Problems solved by technology

However, since the water pumps are made of cast iron or steel, the motor and the impeller will vibrate violently during operation. The vibration of the water pump and the isolation vibration will be transmitted to other surrounding components, resulting in vibration and resonance of the pipeline and noise pollution. environment, affecting the accuracy of measuring instruments and reducing the service life of surrounding facilities

[0004] In the existing technology, water enters the water pump through the water inlet channel, and the energy of the vortex is formed by the impeller, so that the water is thrown out and sent to places or far away. The anti-cavitation performance of the water pump is low, and because the pressure is provided by the impeller, the vibration and noise of the water pump are large, the operation is unstable, the maintenance cost of the water pump is high, and the service life is short
