Self-adapting booster pump for low water pressure increase of high-rise building

The invention discloses a self-adapting booster pump for low water pressure increase of a high-rise building. The self-adapting booster pump comprises a drive device and a pressurization cavity with a water inlet and a water outlet. A pressurization pump is arranged in the pressurization cavity. A drive shaft of the drive device is fixedly connected with a transmission shaft of the pressurization pump. The water inlet is provided with a one-way valve. A controller, a flow sensor arranged at the water inlet and a pressure sensor arranged at the water outlet are further included. The drive device is connected with the controller, the controller is connected with the flow sensor, and the controller is connected with the pressure sensor. The controller detects and controls operation of the drive device according to transmission signals of the flow sensor and transmission signals of the pressure sensor. The controller detects and controls operation of the drive device according to water flow in the water use process of a user and the water pressure of a water inlet pipeline, and water of a tap water pipe can be directly conveyed to high floors without placing a water storage tower on a top floor.
