Fulljet Nozzle

[Lida Rick]

TheDERC Spin-Jet nozzles are designed for cleaning heat exchanger tubes and pipe lines with high pressure water jetting technology. The water flow of your high pressure pump rotates the DERC Spin-Jets. DERC Salotech manufactures a complete range of rotating Spin-Jet tube cleaning nozzles. The DERC Spin-Jets give perfect 360 cleaning results.

For specific cleaning projects the engineers of DERC Salotech will design and manufacture deviating models to your specific needs, in accordance with strict product requirements and safety regulations.

HH Standard FullJet nozzles feature a solid cone-shaped spray pattern with a round impact area and spray angles of 43 to 106.Full Jet nozzles produce a uniform spray of medium to large-sized droplets over a wide range of flow rates and pressures, This uniform spray distribution results from a unique vane design with large flow passages and superior control characteristics.

Full cone nozzles achieve an extraordinarily uniform distribution of liquid over the whole circular impact area. Full cone spray nozzles are free of swirl inserts and therefore particularly non-clogging. Full cone nozzles produce medium to large size drops forming a solid cone shaped spray pattern with a round impact area. The unique vane design features large flow passages to provide superior control and uniform distribution. The full cone spray pattern is ideal for washing, rinsing, cooling, dust control and fire protection.

Shanghai Xinhou was established in 2004, and has nearly 20 years of experience in producing and selling nozzles. In the nozzle industry, we can say without modesty that we are the top five in the industry. Full cone spray nozzles represent the second most common nozzle type in use today. Available in several materials and spray angles, the pattern generated by this type of nozzle swirls the fluid into a full "cone" pattern. Spray nozzle design and precision machining play an important role on the stability of the spray pattern, flow distribution and the spray angles' integrity at various pressures.

Fulljet nozzle can spray uniformly, droplets are from medium to big. This well distributed spray benefits from distinct vane design, big and clear channel, excellent control feature.Full cone nozzle made as precise dimension, which assure accurate and reliable performance. Shanghai Xinhou Company in ensuring the spray effect of each full cone nozzle and its high quality standards, for the full jet cone nozzle appearance is also done to the extreme.

The most commonly used nozzle type in industry is the Full Cone nozzle. These nozzles use a specially shaped vane placed at the nozzle inlet to give a rotational speed to the fluid flowing through the nozzle. Because of the rotational speed of the fluid, water exiting the nozzle orifice is subjected to centrifugal force and opens up in the shape of a full cone. A low flow rate makes these nozzles good for distributing fluids, cooling, washing, and rinsing.

Full cone spray nozzles are commonly used for general washing and rinsing applications that do not require high impact. Narrower spray angle nozzles can be used for cleaning or chemical injection and wider spray angle nozzles tend to be used for dust suppression, fire suppression, coating, general washing, rinsing and other applications. The droplet sizes generated by full cone nozzles range from fine to coarse. Pressure and flow rate and to a lesser degree, spray angle will affect droplet size. If wide surface areas need to be covered or the target is stationary, full cone nozzles may be more appropriate.

The type of spray created by our full cone nozzles is obtained through a specific vortex with a wide passage placed inside the nozzles themselves. This range of nozzles ensures uniform distribution of the drops over the entire covered section.

The main feature of the fan nozzle is its high impact force. However, full cone nozzles can spray uniformly, droplets are from medium to big under big range of pressure and flow rate.This kind of nozzle is suitable to be installed at the area that needs to be completely covered by spray.

Soil erosion by water is globally the main soil degradation process which leaves serious consequences on agricultural land and water aquifers. Splash erosion is the initial stage of soil erosion by water, resulting from the destructive force of rain drops acting on soil surface aggregates. Splash erosion studies conducted in laboratories use rainfall simulators. They produce artificial rainfall which can vary according to type of the rainfall simulator. In this study the aim was to quantify the differences in splash erosion rates affected by rainfall produced by two different rainfall simulators on two silt loam and one loamy sand soil. Splash erosion was measured using modified Morgan splash cups and the rainfall simulators were equipped with four VeeJet or one FullJet nozzle. The soil samples placed under simulated rainfall were exposed to intensity range from 28 to 54 mm h-1 and from 35 to 81 mm h-1, depending on the rainfall simulator. Rainfall characteristics such as drop size and velocity distribution were measured with an optical laser disdrometer Weather Sensor OTT Parsivel Version 1 (Parsivel) by OTT Messtechnik. Rainfall simulator with VeeJet nozzles produced smaller drops but higher drop velocity which resulted in higher kinetic energy per mm of rainfall compared to rainfall simulator with FullJet nozzles. For the same intensity rate measured kinetic energy under the rainfall simulator with VeeJet nozzles was 45% higher than rainfall kinetic energy from rainfall simulator with FullJet nozzles. Accordingly, the average splash erosion rate was 45 and 59% higher under the rainfall simulator with VeeJet nozzles for one silt loam and loamy sand soil, respectively. Splash erosion was found to be a linear or power function of the rainfall kinetic energy, depending on rainfall simulator. The obtained results highlight the sensitivity of the splash erosion process to rainfall characteristics produced by different rainfall simulators. The heterogeneity of rainfall characteristics between different types of rainfall simulators makes a direct comparison of results obtained from similar erosion studies difficult. Further experiments including comparison between more rainfall simulators could define influencing rainfall parameters on splash erosion under controlled laboratory conditions.

Insulin jet injectors can allow people with diabetes to inject insulin without using a needle. However, many people shy away from these small devices because they can be expensive and complex to use. Read on to learn how they work and their pros and cons.

The tiny opening at the end of the disposable injector nozzle usually measures less than 0.009 inches in diameter. This is the same measurement as the 32-gauge needle used in current insulin syringes.

You load the pen by filling the insulin adapter with insulin. Once the device is loaded, you set the gauge to your prescribed insulin dose. Then, you place the device against your skin, typically in an area with some fatty tissue. A good spot could be your stomach, the front or side of your thigh, or the upper, outer section of your buttocks.

When you press the button, the jet forces a high-pressure stream of insulin through the very tiny hole at the end of the disposable injector nozzle. The insulin turns into a vapor that passes through the outer layer of your skin. It then moves through the lower layers of your skin and into your bloodstream.

Compressed gas cartridges typically contain either nitrogen or carbon dioxide. They can produce more pressure than compressed springs, but they cost quite a bit more, weigh more, and need to be replaced more often.

To remove air from the insulin jet injector, disconnect the insulin cartridge and adaptor from the main device. Next, tap the nozzle with your fingertips to bring the air to the top and out of the opening.
