How to improve the spraying effect of atomizing nozzle through purchasing skills

Atomizing nozzle is a product that people seldom touch. It is not a shower nozzle and cannot be used for bathing. It is one of the equipment for farmland sprinkler irrigation, and is often used for watering lawns, factories, agricultural irrigation and so on. In summer, the little thing that you see spinning water spray in the park is the atomizing nozzle. We will introduce the purchase skills of atomizing nozzle and how to improve the atomization effect of atomizing nozzle.

First, the atomization nozzle purchase skills

1, consumers should understand that the core technology of spraying equipment is nozzle. There are landscape-level nozzles and industrial-level nozzles abroad, which have different atomization effects and great differences in prices. Users should choose according to their own needs. The main basis for distinguishing landscape sprinkler from industrial sprinkler is the size of sprinkler aperture grade.

2. Spraying equipment requires high water quality, and the water treatment device is a detail that cannot be ignored. Natural water sources all contain different degrees of impurities, even some harmful substances. If it is not handled properly, it will not only affect the normal operation of the equipment, but also cause harm to the human body.

3, is to check the degree of automation of the control device. The advanced control device can not only realize the functions of automatic switching of system startup and automatic combination of fog shape under the command of preset program, but also monitor the state of equipment put into operation. The computer automatically controls the start and stop of the process and gives an alarm according to the equipment fault signal, thus automatically eliminating the fault and reducing manual operation and maintenance.

Second, how to improve the spray effect of atomizing nozzle

1. Increase the relative velocity difference between the gas phase and the liquid phase to increase the aerodynamic force, so that the droplets will be more finely broken under the greater aerodynamic force.

2. Increase the outlet speed of the liquid-phase nozzle to enhance the collision, so that the relatively ejected droplets are further broken during the collision. It is found that if the exit velocity of droplets is small, they will converge into large droplets, and spraying will lead to humidity in the shed. If the exit velocity of droplets is high, the atomization degree can be improved. However, this will reduce the gas-liquid relative degree and make the pneumatic atomization droplets worse. Therefore, how to adjust the water outlet speed needs users to master it step by step in long-term practice.

3. The experimental results show that the geometry and size of nozzle and mixing tube have great influence on atomization performance. Therefore, when designing the model, we should not only consider their influence on atomization alone, but also consider the change of overall performance after they are combined together.

4. Study the relationship between the flow and pressure of spray water supply system and the geometric size and structural shape of nozzle, so as to improve the atomization effect. The water pressure of special urban water supply system has a great influence on the atomization effect. The higher the water pressure, the finer the water mist particles. But higher water pressure usually brings some problems, such as:

(1) high energy consumption;

(2) All components in the water supply system are under great pressure, prone to failure and short service life, especially the internal spray system on mining equipment.

(3) In addition, it should also be noted that when adjusting the water pressure, do not adjust the pressure of the machine to the maximum value at once, so as to avoid the temperature rise of the machine because it cannot reach the ideal pressure value at the initial start, and reduce the service life of the main high-pressure cleaning machine of the atomizing water supply system. Therefore, when adjusting the water pressure to improve the atomization effect, it is suggested to slowly increase the pressure value. In fact, the low-grade pressure atomization effect of high-quality high-pressure cleaning machine is very good.

Through the above introduction, I believe everyone has a certain understanding of the atomizing nozzle. Atomizing nozzles can be used not only for watering, but also for cooling and purifying air. Because of the high frequency of use. Everyone should choose some big brands when buying.
