What are the types of fountain nozzles and what is their working principle?

Fountains can be seen in all public places such as parks, schools, large hotels or work units, which brings intuitive and beautiful feelings to everyone. Nozzle is an important part of fountain. There are four types of fountain nozzles: scattered fountain, inflatable fountain, compound fountain and rotary fountain, which can spray different beautiful spray. Bian Xiao will share the working principle of fountain with interested friends!

First, fountain nozzle type

1. Scattering nozzle: This type of nozzle has a water distribution chamber on which sneezing or nozzles are installed according to certain rules. When working, each nozzle radiates directly upwards or outwards.

2. Inflatable nozzle: When the nozzle works, the high-pressure water in the nozzle generates negative pressure, which absorbs air and turns the water jet into an impermeable mixing column.

3. Composite nozzle: This is a nozzle that combines two or more different types of nozzles to form various water shapes.

4. Rotating nozzle: This is a nozzle. When spraying water, it automatically rotates the nozzle with reverse thrust to form various water shapes. In the process of selecting fountain nozzle, it is necessary to fully understand the relevant types of fountain nozzle, and rotating nozzle is the most suitable choice.

Second, the fountain nozzle-working principle

1. When the liquid with a certain pressure and speed flows from top to bottom through the spiral nozzle, the external liquid impacts the helicoid on the nozzle at a certain angle, thus changing the injection direction away from the nozzle. The bottom surface of the nozzle is defined as the injection surface, and the helicoids E and E correspond to the upper helicoid E and are defined as a certain distance perpendicular to the injection axis. The plane where droplets form is the atomization surface. Under the microscope, due to the length of the nozzle spiral cone, the atomization surface should be concave spherical, but the length of the spiral cone can be ignored relative to the long atomization distance, so it can be approximated as a plane.

2. Variable frequency motor and pressure regulating pump change the frequency to change the speed of the motor, thus changing the pressure of the pump. The different frequencies of music are sent to the control end of variable frequency motor by single chip microcomputer, so that the speed of motor follows the tone of music. With the change of rhythm and strength, the pressure of the pump also changes, and the water sneezed out varies. And using several sets of equipment to control multiple sets of nozzles and spray different sprays can bring people beautiful enjoyment and make people feel happy.

3. The principle of fountain is momentum conservation. From the large radius pipeline to the small radius pipeline, the speed changes and rushes off the ground. The rotating speed with large radius is driven by the pump, and the rotating speed with small radius is the original rotating speed and momentum conversion rotating speed. It is necessary to select trace elements to calculate the conservation of momentum, so as to get the velocity. This speed is the speed of the net, and then the action of throwing up. This is an ideal situation, no friction, no wind.

To sum up, this is what Bian Xiao introduced about fountain nozzles. In the specific process of purchasing fountain nozzles, people should fully understand the relevant types and working principles of fountain nozzles, give full play to their positive role and bring more aesthetic enjoyment to people.
