"Nozzle", also known as spray nozzle, is a component used in many industries. Agriculture, food, environmental protection, industry, medical and other industries are common areas of nozzles. It is mainly used to control the fluidity of fluids and change the flow speed of fluids. Features such as pressure and range. The small component of the nozzle involves special fields such as fluidics, physics, chemical engineering, and materials engineering. The nozzle originated in the late 19th and early 1920s, and was developed by the famous American chemist and engineer Evans McIntosh. (Evans W. Mcintyre) proposed in 1887 and obtained the nozzle patent in 1888. In the same year, he created the "Mcintyre Spray Nozzle Company" in his name, headquartered in Illinois, which was the first nozzle company in history. , mainly engaged in different types of nozzles and supporting components. With the continuous development of technology and demand, more manufacturers and suppliers of nozzle products have emerged around the world. Well-known companies such as Spraying Systems Co., Lechler, Delavan, BETE Fog Nozzle, etc. Nozzle brand.
There are many different types of nozzles. Different types of nozzles may have different functions and characteristics, so their working principles will be slightly different, but without exception, they all convert liquid into high pressure through a specific nozzle design. The method of spraying, in order to achieve functions such as spraying, sprinkling, and spraying, mainly depends on the shape and size of the nozzle.
● Entry channel: The design of the nozzle channel includes linear, curved, spiral and other designs. When the fluid enters the nozzle channel, different designs of the nozzle will change the flow rate of the fluid.
● Fluid acceleration: When the flow velocity of the fluid changes, it causes the fluid velocity to increase and the pressure to decrease. When the cross-sectional area decreases, the fluid velocity will increase. At the same time, according to Bernoulli's equation, the pressure will decrease when the velocity increases. Therefore, entering The fluid in the channel accelerates and reduces the pressure.
● Jet formation: When the fluid passes through the nozzle, the fluid forms a high-speed jet at the outlet of the nozzle through the conversion between kinetic energy and pressure, thereby forming fine droplets or liquid mist, allowing the gas to form a high-speed airflow.
Nozzles come in a variety of different materials. Common nozzle materials include plastic, PVC, stainless steel, aluminum, brass, etc. These different materials can expand a wider range of use scenarios, such as fire nozzles, which are used in environments where high temperatures occur. and combustion, so nozzles of high-temperature and combustion-resistant materials may be required. In the chemical industry, where high corrosion occurs, specific corrosion-resistant nozzles are also required.
● Spraying and covering: In the automotive industry, nozzles can be used to spray paint or coatings evenly onto the car surface.
● Cooling: In many production workshops, nozzles spray fine water mist to cool the environment and equipment to meet production standards.
● Cleaning: In the food processing industry, fine water droplets are sprayed through nozzles to clean various dirt on the food surface.
● Dust removal and purification: In mining and construction sites, the turbid air caused by production can be effectively purified by adjusting the spray pattern of the nozzles.
● Mixing: In the chemical and pharmaceutical industries, nozzles can be used to mix and disperse a variety of raw materials to achieve refined production standards.
● Spray: In agriculture and gardening, nozzles can spray pesticides and nutrient solutions evenly on crops to ensure the absorption of nutrients.
● Drying: The drying function of the nozzle can be used in the bottle cleaning production line to dry the water droplets on the outside of the bottle through high-speed air flow.
● Lubrication: In industrial scenarios, nozzles can spray lubricating oil for lubrication between equipment and gears.
