The invention discloses an intelligent constant-pressure water supply unit. The intelligent constant-pressure water supply unit comprises a water pump and a frequency converter cooperating with the water pump, the frequency converter is in control connection with the water pump through a wire, a water inlet and a water outlet of the water pump are provided with a water inlet pipe and a water outlet pipe respectively, moreover, the water outlet pipe is connected with a connecting pipe, moreover, a pressure sensor is arranged in the connecting pipe, the pressure sensor is connected with a controller, moreover, the controller is connected with the frequency converter, and the controller and the frequency converter are both arranged on a mounting plate. According to the intelligent constant-pressure water supply unit, the water inlet pipe extends to the inner bottom of a water storage tank, moreover, a liquid level sensor is arranged in the water storage tank, the water inlet pipe is arranged at the top of the water storage tank, an electromagnetic valve is arranged on the water inlet pipe, the electromagnetic valve and the liquid level sensor are both connected with the controller, the water storage tank is used for realizing water supply of the water pump, so that the water supply is more stable, meanwhile, the water level sensor and the electromagnetic valve are used for detecting the water level of the water storage tank and controlling water adding, and in this way, the phenomenon that water storage tank has no water can be avoided.
Description
technical field [0001] The invention relates to a water supply device, in particular to an intelligent constant pressure water supply unit. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. The technical parameters of pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotating blades and water...
