Description

Technical Field

[0001] The utility model relates to the technical field of secondary water supply, in particular to an energy-saving secondary water supply device. Background Art

[0002] Secondary water supply refers to the form in which units or individuals store and pressurize urban public water supply or water supplied by self-built facilities, and then supply it to users or for their own use through pipelines. Secondary water supply is mainly established to compensate for the lack of pressure in municipal water supply pipelines and to ensure water supply for people living in high-rise buildings.

[0003] When performing secondary water supply, water pumps are generally used to work. The imbalance of rotating parts such as the impeller of the water pump causes the water pump to vibrate during operation, causing structural vibration noise. These sounds are directly transmitted through walls or pipes to affect the lives of nearby residents and cause noise pollution. When resting at night, the impact of noise will be more obvious, seriously endangering the health of residents. In addition, abnormal vibration will reduce the service life of devices such as water pumps, thereby increasing maintenance costs. Therefore, an energy-saving secondary water supply device is proposed. Utility Model Content
