Description

Air-cooled household permanent magnet variable frequency self-priming centrifugal pump Technical Field The invention relates to a household booster pump, in particular to an air-cooled household permanent magnet variable frequency self-priming centrifugal pump. Background 1. The traditional household booster pumps are mostly vortex pumps, and have the problems of high noise, low efficiency, incapability of debugging constant pressure, low rotating speed and large volume, and the overflow parts are mostly cast iron materials and often have rust water. 2. Recently, the centrifugal booster pump is changed, and the problem still exists that the noise of the whole machine still does not reach the satisfactory degree of users, and the centrifugal booster pump has large volume, heavy weight and high manufacturing cost and does not have the self-priming function. 3. The traditional water pump has an unsatisfactory visual effect, is especially applied to families, is arranged at home, and is abrupt, so that the indoor overall visual effect is affected. Disclosure of Invention The invention aims to solve the problems in the prior art and provide an air-cooled household permanent magnet variable frequency self-priming centrifugal pump, which adopts a centrifugal pump for boosting a household water pipeline, avoids the situation that water cannot be fed when air exists in a water inlet pipe and the water inlet pipe has no inlet pressure, achieves the aim of quickly and stably boosting, changes the structure of a fan cover, adopts a fan cylinder with two open ends and is matched with a ventilation hole on a housing, ensures that the ventilation hole and the fan cylinder are matched to form the effect of the traditional fan cover, simplifies the structure of the fan cover, reduces raw material consumption, improves the ventilation effect by arranging the ventilation hole on the housing, improves the effect of an air-cooled cooling motor, and is also beneficial to reducing fan noise.
