The so-called programmable fountain refers to running multiple programs randomly according to pre written programs. Fast response and high sensitivity. Using high-performance industrial control computers as user terminals, operating interfaces, and controlling corresponding load actions. The system has high adaptability, high reliability, outstanding performance, and can withstand vibration, impact, dust, and large temperature changes. By utilizing a modular structure, the maintenance of the system is simplified, making it easier to upgrade. The characteristic of a programmable fountain is to design control programs based on pre-set arrangements and combinations of various water types and lights, and send control signals through computer operation programs to make various changes in water types and lights. Stainless steel programmable fountain water pump unit product usage conditions: 1. When the rated head of the stainless steel fountain pump is less than 10m, it is allowed to submerge underwater at a depth not exceeding 10m; 2. When the rated head of the stainless steel fountain pump is greater than 10m, it is allowed to submerge underwater at a depth not exceeding 40m; 3. The water temperature of the medium shall not exceed+40 ℃; 4. The sand content in water or the volume ratio of solid particles that are insoluble in water shall not exceed 0.1%, 5. The particle size shall not exceed 0.2mm; 6. Generally, clean water at room temperature, such as well water, river water, or slightly corrosive liquids; 7. The power supply should be three-phase 50 Hz, with a rated voltage of 380 volts, and its supply voltage must be within the range of 342-420 volts 8. Stainless steel fountain pumps should be used within the applicable range near the rated head; 9. Stainless steel fountain pumps should be equipped with corresponding starting protectors and reliably grounded.
人在舞蹈时，会通过舞姿表现某种情绪，程控喷泉也能通过自己的水型表现出欢快或轻柔的情感。尤其是在乐曲悠扬的时候，水型的变幻似乎被赋予了更多的情感色彩。这智能化的设计是怎样控制的呢？喷泉公司致力于音乐喷泉设计★施工的水景企业，公司专注音乐喷泉★广场喷泉★水幕电影★水上喷泉★人造雾等技术的研发与推广。喷泉公司专业喷泉设计施工制造企业:集喷泉设计、制造、安装、后期维护为一体的专业喷泉公司。主要承接：音乐喷泉★程控喷泉★旱式喷泉★小区及广场喷泉等各类喷泉工程。 程控喷泉的原理是利用了音乐文件的物理波形，将其分为若干乐段，精度达十毫秒，并且自动识别震撼、思念、抒情、喜悦、激昂、悲哀、欢快、热烈等乐曲的基本情感特征，然后再转换为喷泉的控制信号。经过同步处理后，通过信号输出卡输出到外围具体控制单元，即根据水型组态规则控制潜水泵、电磁阀、水下彩灯和变频器等执行机构，将视觉感受与听觉感受融为一体。 在我们平时观看程控喷泉的时候常常会遇到这种情况：乐器演奏到高潮时，当水柱喷到最高点，伴随乐曲声还有类似礼炮一样的声音，这是怎么回事？其实，这是在表演方案中运用了最新的气爆技术，通俗地讲可称为迎宾礼炮。据了解，气爆喷泉技术目前在国内音乐喷泉中并不多见，它往往在交响乐中出现，目的是把广场气氛推向高潮。 顺便普及一下气爆喷泉的原理：由空气压缩机、高压气罐、阀门、喷头几部分组成。喷泉表演时，空气压缩机将高压气罐内空压事先加压到一定压力，气爆表演时，阀门瞬间打开，高压气体将喷头中水流冲向空中形成一股粗壮的水汽结合体，随之产生爆破声效。该类喷泉的水柱喷射由特质电磁阀控制，开闭速度快，可以快速跑动，产生摄人眼球的效果。
A fountain is a combination of water that is sprayed through a nozzle under a certain pressure and has a specific shape. Nowadays, fountains are generally artificial landscape fountains that rely entirely on fountain equipment. The main method is to achieve rhythm and rhythm through the control of a frequency converter. The water shape in the music fountain is rich, and combined with lighting, it gives people a real and intuitive beauty. The various swings in the music fountain can make people feel the soft beauty of the fountain. The emergence of radial swaying is due to the installation of a swaying mechanism under the water surface, which makes the water scenery beautiful and attractive, giving people a magical feeling, and is a manifestation of the development of high-tech in the era. The changes in the position and movement speed of a swinging fountain are important factors in producing a swaying water style and cool breeze. The position sensor of the fountain swing mechanism should be a waterproof non-contact positioning device. We often use Hall sensors induced by magnets, photoelectric sensors guided by optical fibers, or rotary position encoders attracted by magnets. For example, for a fountain swing mechanism using a position encoder, the positioning device includes a position encoder installed on the swing motor shaft, a high-speed counter, a control computer, and a communication interface. Due to the large clearance of the connecting rod of the swing mechanism, in order to achieve precise positioning, the swing mechanism can only reach the positioning point from one direction to ensure its repeated accuracy. Therefore, when the swinging mechanism needs to stop, it must always reach the positioning point from one direction. The positioning accuracy of the swinging mechanism is affected by the motion torque and resistance torque. The motion torque is determined by the power supply voltage of the motor and the motion speed before stopping, while the resistance torque is composed of the friction force of the swinging mechanism, the speed of water flow, and the surrounding wind force. It can be seen that these are factors that cannot be determined in advance. So, in order to achieve precise positioning, we must change its control parameters every time. There are generally two control parameters for precise positioning using electric motor energy consumption braking, namely the magnitude of DC braking current and the starting braking time. A more convenient way for computer control is to change the braking time. In the control system, the braking time of the electric motor can be corrected by detecting the deviation of the positioning point. Based on the statistical data of the positioning deviation value of the swing mechanism, the braking time is finally determined through mathematical model calculation.
