Hydraulic nozzles
What are the characteristics of hydraulic nozzles
Hydraulic spray nozzles, also known as single-fluid nozzles, atomize liquids by forcing them through a small orifice at high pressure. The droplet size of the hydralic nozzle is directly influenced by the liquid pressure. Higher pressure generally leads to smaller droplets. Hydraulic nozzles can produce different spray patterns, including flat fan, solid stream, full cone, and hollow cone.
Characteristics
- Single-fluid
- Reliance on liquid pressure
- Larger droplet size than two-fluids
- Different spray patterns
Selecting the most suitable spray pattern for your hydraulic nozzle
The spray pattern describes the cross sectional shape of the spray. By selecting the spray pattern most suitable for the particular application the most efficient spray performance will be achieved. As can be seen below, the spray pattern changes with the gradual increase in spray pressure.
Flat fan: Increasing pressure generally widens the spray angle and coverage.
Hollow cone: Higher pressure generally expands the spray angle and the diameter of the ring-shaped footprint.
Full cone: Pressure changes can affect both the spray angle and the uniformity of the circular footprint.
Square full cone: Operating outside the intended pressure range can distort the square footprint, making it more rounded.
Spray angle and width
The spray angle is the angle of spray measured near the nozzle orifice. The table below shows the calculated spray width, based on the spray angle. The spray width varies depending on the spray height. As the spray goes farther from the nozzle, the droplets gradually lose momentum and the covered area will not continue to increase at a certain distance from the nozzle orifice. Be aware that the actual spray width is smaller than the calculated values. This needs to be considered when designing a nozzle layout.
Spray impact
Spray impact describes the force with which the spray droplets hit the target surface. The stronger the spray impact, the better the cleaning effect. Solid stream jet nozzles have the strongest spray impact (see Fig. 1). The wider the spray angle and the larger the spray area becomes, the weaker the spray impact. The spray impact also decreases as the distance between the nozzle and the object increases.
Guarantee of spray angle
In regards to the flat spray and cone spray nozzles, they are guaranteed to have a rated spray angle within the range of +/- 5°, under a standard pressure. The solid stream jet nozzles, on the other hand, have a guaranteed axis of coverage angle from the nozzle’s centerline, within a range of 3°, under a standard recommended pressure.
Furthermore, we provide hydraulic spray nozzle for a specific width request, which can either be wide spray angles or of narrower spray angles. Within these categories we recommend our cone spray nozzle and flat spray nozzle.
Choice of materials depending on your application
In order to satisfy the needs and applications of the customers, Ikeuchi has implemented the development of nozzles from various materials suitable for each particular request and demand. The material of construction for the parts of the nozzles can vary from stainless steel, rubber, ceramic to plastic. Depending on the usage or purpose of the nozzles, Ikeuchi provides hydraulic nozzles manufactured from various types of stainless steel, ceramic and plastic, or from a combination of materials.
Due to the overuse of nozzles or usage under unrecommended conditions, the nozzle orifices could be constantly placed under pressure of abrasion. However, for demanding applications and requirements, the ceramic spray nozzles have proven to be manufactured out of an outstanding wear-resistant material, lasting 20-30 times longer than stainless steel nozzles (advantages of ceramic nozzle).
Benefits of using Ikeuchi spray nozzles
Cost efficient
Ikeuchi spray nozzles are known for their high wear resistance. For the highest wear resistance you should try our ceramic spray nozzles.
A high quality spray nozzle will maintain its spray pattern and spray distribution for longer, which will lead to less water waste.
Due to less frequent clogging issues or the need to replace spray nozzles, our nozzles lead to less downtime in your production.
Guaranteed performance
Ikeuchi is an expert in spray nozzles since 1954, which ensures you the highest quality and expert knowledge in this field.
All our spray nozzles are developed and produced in-house. This ensures the highest possible global standard.
At Ikeuchi we offer guarantee for spray capacity and spray angle with an accuracy of + or – 5 % and 5 degrees.
