"Nozzle" - what is it, definition of the term
The term denotes an engineered aperture that shapes, accelerates, or restricts the flow of liquid or gas, converting pressure into kinetic energy to create a directed jet; it typically comprises a converging‑diverging passage and may incorporate internal contours to achieve specific spray patterns, atomization, or thrust characteristics.
Detailed information
A spray tip is a precision‑engineered component that converts pressurised fluid into a directed jet. The internal passage narrows to a calibrated opening, creating a pressure drop that accelerates the liquid and determines droplet size. Material selection—commonly stainless steel, brass or high‑density polymer—balances corrosion resistance with wear tolerance. Surface finish, measured in micro‑inches, influences flow consistency and prevents clogging when viscous or particulate‑laden solutions are used.
When applied to ectoparasite management, the device delivers insecticidal formulations onto hosts or environments where ticks, bugs, lice and fleas reside. The following characteristics affect efficacy:
- Orifice diameter – smaller openings produce finer mist for thorough coverage of fur or fabric; larger apertures generate coarse spray suited for open‑area treatment.
- Spray angle – narrow cones (15‑30°) concentrate the jet for spot application; wide cones (90‑120°) ensure blanket coverage of bedding or vegetation.
- Droplet spectrum – measured in microns; droplets between 50–150 µm penetrate insect cuticles without excessive runoff.
- Pressure rating – compatible with pump output ranging from 20 psi for low‑viscosity solutions to 120 psi for high‑viscosity emulsions.
Selection guidelines for pest‑control operations include:
- Identify target species and habitat (e.g., fur, carpet, pasture).
- Match orifice size to required droplet range.
- Choose spray angle that aligns with treatment geometry.
- Verify material compatibility with active ingredients to avoid degradation.
- Confirm that the pump system can sustain the specified pressure without fluctuation.
Routine maintenance extends service life. After each use, flush the passage with a solvent compatible with the previous formulation, then rinse with clean water. Inspect the tip for mineral deposits or abrasion; replace if the opening deviates by more than 5 % from the original specification.
Performance testing employs a laser diffraction analyzer to quantify droplet distribution and a high‑speed camera to verify spray pattern symmetry. Data recorded under controlled pressure validate that the device meets design tolerances before field deployment.
In integrated pest‑management programs, the dispensing head integrates with automated sprayers, handheld pressure vessels and backpack units, providing flexibility across residential, agricultural and veterinary contexts. Its ability to deliver precise, repeatable dosing enhances treatment reliability while minimizing chemical waste.
