The fountain is a kind of water or other liquids after a certain pressure through the nozzle spraying assembly has a specific shape, generally provide hydraulic pumps, after years of development, now has gradually developed into several categories: music fountain; music program-controlled fountain; + program-controlled fountain; laser water curtain film; taste fountain. Specific lighting control system, in addition, to purify the air, beautify the environment.
The working principle of music fountain is to control the water column according to the music, music and achieve synchronous effect, and the water column is controlled by the water pump, and the pump is composed of three-phase asynchronous motor, three-phase asynchronous motor speed if pass into the power supply, the speed is not changing, inverter is the special device for motor the speed of the. The speed of the motor is controlled by the frequency converter, and the water column is changed.
Change the frequency to change the motor speed, will change the pump pressure, different frequency of music processing by the MCU to control the motor end, the rotating speed of a motor with the music rhythm, tone, and intensity change, change the pump pressure, spray out water will have a level of change, but also by the several sets of equipment for multi nozzle control group
The fountain is formed by the water pump.
Turn the rhythm and intensity of the music into control signal. This signal controls a voltage control device again. After the power goes through this voltage controller, the output voltage changes with the change of music, and then controls the pump motor.
