Why a Nozzle Should Not Be Chosen Based On Orifice Diameter?

Non-specialized nozzle retailing platforms and no-brand standard market nozzle manufacturers tend to see nozzles through a perspective of simple, rigid machining processes – they often consider the only important requirement for a nozzle is the orifice diameter. However, the nozzle orifice diameter is not always so easily defined, take the example of the fan-shaped nozzle – its orifice is in the shape of an olive (or an eye), making it impossible to determine its orifice diameter by mere observation.

Principle of two fluid spray nozzles

Compared with other nozzles, the structure of two fluid spray nozzles is more complicated. There are 2 flow tunnels for gas and liquid inside the nozzle. Due to air and liquid tightness requirements, two fluid spray nozzles are usually designed with multiple pieces. This complexity makes its manufacturing more expensive.

Principle of cone spray spiral nozzles

For perfect cone shape spraying, the structure inside the cone spray nozzle must include 2 features, a chamber with a machined curved structure and a multi-slotted core or an X core set in the chamber.

Principle of Flood type-Spiral Nozzles

After liquid flows to a nozzle from the pipe forced by pressure, the liquid flows and impacts the curved structure inside the nozzle.

Principle of flood type spray nozzles

The flood type nozzle is known as low pressure wide angle flood nozzle.

Principle of hollow cone spray nozzles

When liquid flows into the chamber in the hollow cone spray nozzle, through the chamber structure, it will whirl in the nozzle like a tornado. When it flows to the spout, it will pass a curved surface which lead it to be sprayed out (thrown out) as hollow cone shape.

Principle of fan spray nozzles

After liquid flows to a nozzle from the pipe forced by pressure, when it passes by the spray orifice, it will be extruded by the orifice with an oval-shaped structure. As the pressure of the extrusion is not able to be released, the liquid flows out of the orifice to both sides which makes the spray shape is similar to a fan. That is why this kind of spray is called “Fan spray”.

Principle of Fan Spray Nozzles

When the liquid passes the orifice through the pressure special for the fan spray nozzle, the disturbance is generated through the process.

5 Factors How Nozzle Tolerance Affects the Yield

The professional level of an industrial nozzle product manufacturer depends on the product's tolerance accuracy of 0.01 or less. Every nozzle manufacturer must pay special attention to the pursuit of tolerance.

4 useful features of LORRIC nozzle flow rate chart

World common pressure units for flow rate measurement are such as kgf/cm², MPa, bar, psi, etc. The adoption of each area or country may be varied. For Taiwan, the most common pressure unit is kgf/cm² which is also Taiwan standard unit in pressure measurement. LORRIC’s brand-new flow chart not only provides easy reading but also helps to quickly find out the spray angle and capacity code users need.
