Vacuum pump, pipeline system, actuating system, valve system, control system and air chamber, these different equipment and systems cooperate with each other to form a vacuum wave maker.

工作原理：

working principle:

控制系统发送一个信号到制动系统，制动系统的运转指挥着真空泵改变气室中的水位。控制阀的开启和关闭是按照系统中预先设计的波的频谱来实施的。这一系列的作用结合起来最终产生了波浪。由真空造浪机制造出来的波浪的高度可以达到两米以上，这样的大浪在向周围的扩散中极其壮观。这样的真空造浪机结构复杂实施起来难度大，代价高，这样就决定了真空造浪机的应用范围限定在了大型冲浪滑板造浪池和试验用池中。

The control system sends a signal to the braking system. The operation of the braking system commands the vacuum pump to change the water level in the air chamber. The opening and closing of the control valve is implemented according to the frequency spectrum of the wave designed in advance in the system. This series of actions combine to produce waves. The height of the wave produced by the vacuum wave maker can reach more than two meters. Such a big wave is very spectacular in its diffusion to the surrounding. The structure of such vacuum wave maker is complex, the implementation is difficult and the cost is high, which determines that the application scope of vacuum wave maker is limited to large surfing skateboard wave making pool and test pool.

造浪池的真空推动原理的分析：

Analysis of vacuum Propulsion Principle of wave making pond:

造浪方式利用多台真空泵把气室里的空气抽干。真空泵通过铺设的管道对气室里的空气进行往外排，随着抽取空气的程度的加深，气室里的空气越来越少，相反真空的程度越来越高。这时造浪池中的水就会大量的充入气室，当气室里的水达到一定的程度时，通过控制设备打开气室的控制阀。这时，外面的空气就会通过管道重新进入气室里，气室里的真空度越来越低。由于重力的作用，水伴随着巨大的能量从气室里流出来，这时就会产生所要的人工波浪。有时人工波浪可以达到0.3-3.0米左右，浪形4-8种。但这要由设备的配置情况和造浪池的大小决定。由于制造波浪所需要的设备较多，系统较为复杂，同时造浪池要占大量的土地，所需建设费用也较高。

In wave making mode, multiple vacuum pumps are used to dry the air in the air chamber. The vacuum pump exhausts the air in the air chamber through the laid pipeline. With the deepening of air extraction, the air in the air chamber is less and less, on the contrary, the degree of vacuum is higher and higher. At this time, a large amount of water in the wave making pool will be filled into the air chamber. When the water in the air chamber reaches a certain degree, open the control valve of the air chamber through the control equipment. At this time, the outside air will re-enter the air chamber through the pipe, and the vacuum in the air chamber is getting lower and lower. Due to the action of gravity, water flows out of the air chamber with huge energy, and the required artificial waves will be produced. Sometimes artificial waves can reach about 0.3-3.0m, with 4-8 wave shapes. However, this depends on the configuration of equipment and the size of wave making pond. Due to the large amount of equipment and complex system required for wave making, at the same time, the wave making pond occupies a large amount of land and the construction cost is also high.

在具体选择造浪机的种类时要充分结合业主的要求和产品的技术参数。在产品技术参数一定的情况下，不同的场地，在波浪的样式、种类、高度等方面有不同的要求。造浪设备和系统要尽量放置在深水端。在造浪池的水循环方面，应在浅端设置排水沟，进水方式设计为池底均匀进水。控制平衡水池的进水和排水间接的控制造浪池中水的平衡。要对造浪池中的水定期性的消毒，保持平衡水池水中游离氯的浓度应不低于水池中的数值。造浪池制浪时，用采取防止池水回流的措施。造浪池的人数负荷按每人2.5平方米计算，池水循环周期宜小于9小时。

When selecting the type of wave maker, it is necessary to fully combine the requirements of the owner and the technical parameters of the product. When the product technical parameters are certain, different sites have different requirements on the style, type and height of waves. Wave making equipment and systems shall be placed at the deep end as far as possible. In terms of water circulation of the wave making pond, a drainage ditch shall be set at the shallow end, and the water inlet mode shall be designed as uniform water inlet at the bottom of the pond. Control the inflow and drainage of the balance tank, and indirectly control the balance of water in the wave making tank. The water in the wave making pool shall be disinfected regularly to maintain balance. The concentration of free chlorine in the pool water shall not be lower than that in the pool. When making waves in the wave making pond, take measures to prevent the backflow of the pond water. The number of people and load of the wave making pond are calculated as 2.5 square meters per person, and the water circulation cycle of the pond should be less than 9 hours.

人工造浪工程是涉及到了力学领域、机械学以及电气控制系统学等几门学科。波浪在不停的扩散的过程中需要消耗大量的能量，因此，在设计的过程中要充分的考虑深水区与浅水区的特点和差异。波浪在深水区的高度大但是面积较小，而在浅水区刚刚相反。一般来说正常的造浪池的水深要达到1.5～1.8m，池底坡度不能大于８％。同样的造浪设备在好的造浪池当中产生的波浪形态较好，在扩散的过程中相互作用甚至产生一些共振等效果，但在设计不好的池中没有这方面的表现，因此在设计的过程当中就要充分考虑造浪池的形状。

It involves several disciplines, such as mechanics, electrical system control and so on. Waves need to consume a lot of energy in the process of non-stop diffusion. Therefore, the characteristics and differences between deep water and shallow water should be fully considered in the design process. In deep water, the height of waves is large but the area is small, while in shallow water, it is just the opposite. Generally speaking, the water depth of a normal wave making pond should reach 1.5 ~ 1.8m, and the slope of the bottom of the pond should not be greater than 8%. The same wave making equipment produces better wave shape in a good wave making pool, and even produces some resonance effects in the process of diffusion, but it does not show this in a poorly designed pool. Therefore, the shape of the wave making pool should be fully considered in the design process.
