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.

Introduction of nozzle’s connector

LORRIC provides nozzles in various ways to be installed on equipment or pipes. The most common way to install nozzles is external thread (aka male thread). Besides, there are more ways, like internal thread (aka female thread), flange type, welding type, and clamp type. Among them, the welding type could be classified to 2 types, spray pipe and plate positioning.

Impact vs pressure distribution

1. Impact is total force: Which is proportional to flow rate. /Which is proportional to the square root of pressure. 2. The definition of pressure distribution is the pressure which is sprayed to every part of workpiece by nozzles.: Variation of impact will effect pressure distribution. /The result of pressure distribution will be effected by spray shape and coverage volume. /Pressure distribution is related to spray flow rate and effected by the design of flow distribution. /As there is so many variables, there is no any simple formula to receive pressure distribution of various nozzles.

Comparison of particle size of 3 common kinds of nozzles

Three features of particle size

3 facts you must know about “spray angle”

The definition of “Spray angle ” is the angle of spray shape. (please refer to schematic diagram) We lists following 5 easy sentences for you to quick understand what is “spray angle”

Immediately understanding how to read “Flow Rate”

Unit: LPM ( L/min ) Features: • Greater the pressure, greater the flow rate. • Flow rate and pressure are not linear relationship. • For example, the flow rate of a nozzle under 8kg/cm2 pressure is not double when it is under 4kg/cm2 pressure.

Full cone nozzle’s estimated spray coverage

Full cone nozzle spray coverage is affected by a myriad of factors, such as gravity, acceleration and air resistance. That combined with the technical specifications of the nozzles themselves which dictate spray pressure and viscosity, thus further influencing spray coverage, all lead to the fact that there’s no way to predict nozzle spray coverage in a completely accurate manner. Thus, the following information is a theoretical estimation, prior to the influence of external factors. For further information regarding more practical spray coverage, be sure to contact our sales rep.

How to properly clean a nozzle?

Nozzle blockages might occur in occasions when the filtering system’s ability is insufficient, or when nozzle’s flow rate is relatively low. In order to avoid these, the nozzles should be routinely cleaned, per the following instructions.

Flat fan nozzle’s estimated spray coverage

The Seven Cornerstones for Choosing the Correct Nozzle

LORRIC provides several different kinds of nozzles, for the usage of different industries, and to accommodate different manufacturing processes and the problems they face. The following seven points serve as a reference guide in choosing the correct nozzle for your needs.
