Problems solved by technology

[0006] The structure of this mechanically driven water pump controller is relatively complicated, and it has poor sensitivity to the water pressure in the water supply pipeline, and cannot well reflect the actual water supply situation, which may cause the water pump to work in an inappropriate state. , which is not conducive to reducing energy consumption and cannot guarantee the service life of the pump
In addition, the elasticity of the diaphragm will change with the passage of time. If the diaphragm is seriously aged, it needs to be replaced in time, otherwise the water pump controller will not work, which also increases the trouble of maintenance during the use of the water pump controller.

Embodiment Construction

[0034] As shown in the figure, the structure of the constant pressure variable frequency water supply system of the present invention includes a controller 3 and a water pump 1, and the controller 3 is electrically connected to the water pump 1 through a frequency converter. The casing of the controller 3 is provided with a computer chip, a pressure detection system, a flow detection system, and a pressure regulation system, and the computer chip is electrically connected to the pressure detection system, the flow detection system, and the pressure regulation system. Both ends of the controller 3 are respectively connected to a water inlet pipeline 2 and a water outlet pipeline 4 , and the channel running through the controller 3 communicates with the water inlet pipeline 2 and the water outlet pipeline 4 . The water pump 1 is connected to the outer end of the water inlet pipeline 2 , and several faucets 6 are arranged on the water outlet pipeline 4 .

Abstract

The invention discloses a small water supply system and a constant-pressure control method thereof. The small water supply system comprises a water pump and a controller. The controller comprises a shell. A computer chip, and a pressure detection system, a flow detection system and a pressure adjustment system which are electrically connected with the computer chip are arranged in the shell. The water pump is electrically connected with a frequency converter. The frequency converter is electrically connected with the computer chip. A through passage is arranged in the shell. The passage is connected with the water pump through a water supply pipeline. The passage penetrates through an installation chamber in the shell. A spool with a valve stem is arranged in the installation chamber. The spool is used as part of the flow detection system and can move in the installation chamber. The pressure detection system stretches into the passage. The pressure adjusting range of the pressure adjustment system is set to be 50-70 percent of the rated lift of the water pump. Since the water pump is controlled through the computer chip, the pressure adjustment system, the pressure detection system and the flow detection system, the water supply system can supply constant-pressure water and the pressure difference of water received by different users can be eliminated.

Description

technical field [0001] The invention relates to a water supply system, in particular to a small water supply system applicable to water supply for small hotels, restaurants, high-rise buildings and household water and a constant pressure control method thereof. Background technique [0002] In the water supply process of small hotels, restaurants, high-rise buildings and domestic water supply, due to the water source or the water supply system itself, the water pressure is often unstable, which will bring inconvenience to these places. The usual way to alleviate this phenomenon is to use a water storage tank, but the water storage tank will inevitably communicate with the outside world, and the water is easily polluted, which will affect the quality of the water. [0003] A Chinese utility model patent (Patent No.: 201120438183.7) discloses a constant-pressure water supply system, which includes several water pumps, accumulators, output pipes and frequency converters for wat...
