How to Detect the Nozzle Failure?

Nozzle problems can be monitored

The function of nozzle problems is minor initially, so are often ignored. With the change of the throat, the change of spray characteristics is gradually obvious, and can be monitored.

Particle size: With flat fan nozzle wear or corrosion, the flow increases, the pressure drops, resulting in larger spray particles. This problem usually cannot be found out, but can be analyzed through the application of the results.

The nozzle alignment: when a nozzle is installed with multiple fan nozzles, it requires a complete uniform coverage, requires that all nozzles can accurately position, that is, all the fan-shaped spray pattern can accurately align, to ensure accurate coverage area. All spray must be mutually parallel, and form a 5 °- 10 ° corner with the nozzle. Otherwise, the entire coverage will be uneven.



Flow: When using centrifugal pump, the throat constantly wears, the nozzle flow usually increases under certain pressure. Because the increase in the flow is not easy to conceive, it is recommended to carry out regular flow detection. The flow detection can be read by detecting the flow meter, or using the collection method at a given pressure to collect water quantity within a certain time for measurement.

Spray shape: when fan spray nozzle throat is damaged, blocked or bond, the non-uniformity of the spray pattern changes is very easy to be found. And when the throat gradually wears, the spray shape of the change is not easy to be conceived, which can be found until the flow rate is increased substantially. For the applications require a very uniform spray coverage, it requires using special equipment or test to detect the uniformity of the spray pattern.

The spray shape of fan nozzle with elliptical throat is thick fan or tapered edge blade-shaped, and thus the overlap distribution of adjacent nozzles is very satisfactory. Angle contained in the spray pattern will be able to be found to reduce when the throat wears. You will find more water flow in the center, so that the water distribution increases. You can also find it is strip, hollow in the spray shape.

Hollow cone nozzle - basically a liquid ring, the uneven spray pattern is mainly performance the form of bars in certain areas. Solid cone, square, or oval-shaped spray nozzles, the spray shape unevenness is the same with the fan nozzle to some extent, and more water will be concentrated in the center. The spray pattern changes caused by the clogging of the solid inside the nozzle blades are not regular.

The Application of Nozzle in Ship

First, the promotion of ship is inseparable from the application of the nozzle, the operation of ship relies on spects spray water is to the back of the hull to help the boat forward, relying on the reaction force of the water to drive the boat forward, of course, it can meet the atomizing nozzle is not an ordinary nozzles need to withstand a lot of pressure, and resistance to water , but also be able to adapt to a variety of waters, to meet the general material to meet in a variety of waters is not, first of all the various water pH are different, and it failed to find conditions waterborne, so the The material must be special to adapt to the needs of the boat.



The importance of nozzle

For such special requirements of the boat, the nozzle needs to have a strong impact, to ensure the vessel's normal high-speed. The running speed of ship is achieved to forward by the momentum of the boat, we should control the injection to meet the ship's steering needs. For the development of China's shipping industry, marine nozzle will also be improved and perfected to meet the needs of the ship. Of course, marine nozzle is not only the drive of the rear portion of the ship as well as the cleaning of the dirt on board, it also needs specialized marine washing nozzle to wash to meet the clean in the ship running, in addition, the disinfected treatment on board also needs to be completed by flat fan nozzle to maintain the normal operation of ship.

Analysis of the nozzle application prospects

The nozzle is small, but its role cannot be ignored. In the chemical production units of operating device, such as gas absorption, washing liquid distillation, direct heat transfer and atomization burn. The spray tower consist of the nozzles has been popular with its advantages of high efficiency, energy saving, and low cost. As the small investment equipment, the fire nozzle spray system is more and more widely used in the oil and gas tank farm and other flammable occasions. Mine in easy fly ash dust, warehouse, cement plant and powder engineering, the atomizing nozzles with a small amount of water will be able to reduce the amount of dust in the air. The nozzle has been widely used in the petroleum, power, chemical, pharmaceutical, chemical fertilizers, environmental protection and other industries. In recent years, in a variety of industrial sectors, especially in the coal chemical project, PVC project, fertilizer projects, synthetic ammonia and urea project, synthetic rubber items, ship fire cool project, industrial exhaust gas washing purification project, fluorine chemical projects, desulfurization environmental projects, phosphoric acid, phosphorus the ammonium projects, power plant projects, the most are standard and non-standard nozzle and injector with more practical experience, and it is the guarantee for a successfully normal operation of your project.

Various of Industrial Spray Nozzles

Classification of Industrial Nozzle

Industrial nozzle is mostly installed in the spray washer, spray oil, injection, sand blasting, spraying and other equipments, it plays different roles in different equipments, widely used in petroleum, chemical, steel, metallurgy, electronics, cement, food, paper, printing, livestock and other industries. Industrial nozzle includes industrial burners and common industrial nozzle two categories. And general industrial nozzle is divided into the following categories: 1. According to different materials, it can be divided into: metal nozzle, plastic nozzle , ceramic nozzle, and alloy nozzle; 2. According to different spray shapes, it can be divided into the conical nozzle, square nozzle, the nozzle of rectangular, oval-shaped nozzle, fan-shaped nozzle flow column (DC) nozzles, other than the latter two nozzles, they contains both solid and hollow nozzles; According to the fluid nature, it can be divided into single (a) fluid nozzle and dual (b) fluid nozzle and multi-fluid nozzle; According to different applied industries, it can be divided into petrochemical nozzles, agricultural nozzles can be divided into , textile nozzles, nozzle of paper, printing nozzle, environmental protection (desulfurization, denitrification, nitrogen removal, dust, etc.) nozzles, steel metallurgy nozzle, coking nozzle, electronic nozzle, food nozzles, etc.; According to different spraying medias, it can be divided into water nozzle , oil nozzle, the powder nozzle, gas nozzle, mixed-media nozzle, CWS nozzle (such as Texaco, four nozzles).

Classification of Atomizing Nozzle

Generally, there are totally two kinds of atomizing nozzles: First, fine atomizing nozzle. This kind of nozzle has some special features. It can work without the use of compressed air, it can have very fine atomized spray only use the hydraulic pressure. Very small particles, can form a mist spray effect. It is wall mounting type, can be installed in external walls, vessels and piping. A variety of nozzles are removable, convenient and easy to clean and install. The majority of the nozzles have built-in filters. Second, the air atomizing nozzle. Air atomizing nozzle requires a single air source to provide atomizing air. Some models are equipped with automatic cylinder or clear or drying needle, an additional air channel is needed. All models require flow channels. The flow channel through the supercharger equipped with a siphon to transfer or gravity delivery device for the transmission of the liquid. The function of the fine mist, spray and the air atomizing nozzles is the same, that’s to produce very fine atomization effect.

Applications of Flat Fan Nozzle

The flat fan nozzle is also widely used in daily manufacturing processing. Such as the cleaning of metal processing, spray coating, spray cooling, remove grease stains, plating line rinse, and agricultural products; cleaning of spraying and cooling applications such as food, steel, paper and other industries; cleaning of printed circuit boards, display, film and etching process, the rain test, spray cooling, semiconductor cleaning, CPT glass bulb cleaning, LCD glass cutting and cleaning.
