Various 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 nozzles, 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, 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.

Fan Spray Nozzle in Our Daily Life

Appreciable Effects of Fan Spray Nozzle

The fan spray nozzles usually produce a line of spray. The spray angle of the plastic nozzles would decide how long this line is at a given distance from the orifice. Some flat fan spray nozzle usually produces numerous coarse sprays which contain larger droplets while some other designs would deliver fans of finely atomized sprays. Just like other sprays, the effects of a flat fan spray nozzle would be greatly decided by the flow rate and the pressure. Compared with other patterns of sprays, it generates numerous medium impact sprays.

Design Features of Fan Spray Nozzle

This design of the plastic nozzles and the fan spray nozzle impinges and also the spray onto a shaped deflection surface. The surface is so that the deflected spray can be formed right into a fan. This design features the benefit that the fan could be shaped into an extremely hard driving narrow fan appropriate for efficient cleaning or could be spread very widely to achieve optimum coverage. In addition, as the first spray orifice is circular instead of elliptical deflector, nozzles are more clog resistant and hence applicable in the dirty environments or used for spraying more lumpy fluids. Another advantage of deflection nozzles is that they could successfully deal with such situation when the space is constrained. Since the fan is designed at an angle to fill the pipe, instead of concurrent with, it actually can go through a relatively long distance towards the below target. Based on the angle of deflection (different in the spray angle), this can offer the flat fan much longer distance to "spread out". For instance, a deflection nozzle can deflect its spray by 45 degrees and can travel 1.4 times the distance before it hits the surface below.

Applications of Fan Spray Nozzle

The flat fan spray nozzle and the plastic nozzles are widely applied, such as applications in series mounted on the spray bars in the conveyor systems. The movement of the conveyor makes the product travelling below to obtain equal amount of the spray. Changing the speed of the conveyor would successfully control the degree of the spray. Due to above mentioned reasons, the fan spray nozzle can be widely applied in coating, washing as well as lubricating in various industries and during numerous production processes. Just like the flat fan spray nozzle products, you may also find wide range of products of various flow rates, spray angles as well as design styles in the market.

Basics of Various Spray Nozzles

Overall of Industrial Spray Nozzle

The nozzle is designed according to their work in a variety of different spraying conditions, and thus in daily work, we should choose suitable nozzles to fit the actual needs, in order to reach the best spray performance. Characteristics of sprayer nozzles are reflected in the nozzle of the spray type, that’s the formation shape when the liquid leaving the nozzle exit, as well as its operating performance. Generally, nozzles are named after the nozzle spray pattern area, usually it is divided into fan-shaped, conical, plume flow (i.e., jet) air atomization, flat nozzle and spray gun nozzle, and the conical nozzle is divided into two major categories: the hollow cone nozzle and solid cone nozzle; and the name of Venturi nozzle (i.e., mixing nozzle), strong cold (hot) outlet hair nozzles and special nozzles (such as garden nozzles, tank washing nozzles, pipe cleaning nozzles series) reflects the operating performance of the spray nozzle.

Application Field of Plastic Nozzle

Plastic nozzle is mainly used in corrosive chemical industry, the commonly used material of the plastic nozzle are PP, PVC, PVDF and TFEL, the shapes of the plastic nozzle are fan-shaped plastic nozzles, solid cone-shaped plastic nozzles, the threaded connection of the plastic nozzle size are 1/8, 1/4, 3/8, 1/2 etc., many threads are optional. Many other threads of these plastic nozzles are open molding, injection molding, the cost is relatively low, but the amount is large, as for the plastic nozzle with big sizes, it can be made by the CNC garage process, but the cost of machined made nozzles is relatively high. Plastic nozzle application areas: cleaning, pickling line of the semiconductor, circuit board industry electrophoresis tanks, etching, stirring, in short, where there is chemical liquid water there is plastic nozzle, the only disadvantage of plastic nozzle is that the poor wear resistance, i t cannot be high temperature resistant. In a word, each plastic nozzle has its independence and special performance.

Working Feature of Plastic Spray Nozzles

Plastic nozzle has special molded import thread, you can easily screw the nozzle into the nozzle tube. The plastic nozzle will have a six-party or the Quartet, in order to facilitate the use of tools, plastic nozzle should be tightened. The unique design of the plastic nozzle ensures that in the installation process, the plastic spray nozzle design can quick and easy book on the nozzle, when the plastic nozzle of the Quartet or the six-party side is parallel to the plastic nozzle jet, the nozzle has been in the accurate bits, which can save us a lot of time and improve production efficiency.
