Description

Technical Field

[0001] The utility model belongs to the technical field of booster pumps and relates to a high-corrosion-resistant and low-noise booster pump. Background Art

[0002] As the name implies, a booster pump is a pump used for boosting. The booster pump mainly includes a housing, a motor connected to the housing, and a suction chamber. The main working principle of the booster pump is to open the screw plug first, pour water into the suction chamber through the water filling port, and then start the centrifugal pump. The impeller rotates rapidly, and the blades of the impeller drive the liquid to rotate. When the liquid rotates, it relies on inertia to flow to the outer edge of the impeller. At the same time, the impeller sucks liquid from the suction chamber. In this process, the liquid in the impeller flows around the blades. During the circumferential movement, the liquid acts on the blades with a lift. In turn, the blades act on the liquid with a force equal to the lift and opposite to the direction. This force does work on the liquid, so that the liquid gains energy and flows out of the impeller. At this time, the kinetic energy and pressure energy of the liquid are increased. The single-sided clearance of the existing booster pump impeller cavity force is only 0.1mm, which is very easy to rub, and the six-shaped head of the insert is prone to warping during use, which will also cause friction with the impeller. These situations all lead to noise. Therefore, a high corrosion resistance and low noise booster pump is proposed to address the above problems. Utility Model Content
