Sprayer Nozzle hman dan tur kaihhruaina hnuhnung ber: A chi hrang hrang, hman dan leh Droplet Size

2) Droplet lian leh te: coverage vs. drift

Droplet size hi VMD (volume median diameter) hmanga sawi a ni tlangpui. Droplets te a fin poh leh leaf coverage tam zawk i hmu tlangpui ang—mahse drift risk a sang a, a bik takin boom height sang zawk leh thli tleh chak zawkah chuan. Coarser droplets hian drift a ti tlem a, mahse efficacy vawng reng turin tui volume sang zawk emaw adjuvants emaw a mamawh thei.

• Finer droplets  → coverage tha zawk, drift risk sang zawk.

• Coarser droplets  → drift hniam zawk, a chang chuan coverage tlem zawk—tui volume, angle, emaw twin‐fan emaw hmangin a compensate.

• Environment a pawimawh:  khaw lum, vawt leh thli tleh hian evaporation leh drift a tipung a.

3) Pressure, angle leh flow rate—an inzawmna

3.1 Pressure leh flow leh droplet te

• Pressure sang hian flow rate a tisang a, droplet te chu a shift finer zawk bawk.

• I nozzle design chu siamtu chart-ah en fo ang che.

• PSI chauh hmangin coverage chu chase suh—angle, speed leh nozzle size te ngaihtuah hmasa phawt ang che.

3.2 Angle (80° vs. 110°) leh boom san zawng a ni

• Angle zau zawk (eg, 110°) hian overlap inangah boom san zawng hniam zawk a phal a, hei hian drift control a pui a ni.

• Pattern test hmangin overlap tih finfiah rawh; boom-ah 50–70% overlap neih tum ang che.

• Wand-ah chuan angle hian spray zau zawng leh hnathawhna hlat zawng a nghawng a—a san zawng leh a tlan chak dan inang tlangin vawng reng rawh.

4) Calibration: hmanraw chak tak tak, hnathawk thei

Nozzle, pressure, speed, formulation i thlak apiangin calibrate rawh.

4.1 Nozzle pakhat (broadcast swath) hmanga siam a ni.

1. Swath zau zawng (W) chu feet emaw metre emaw-in teh rawh.

2. Catch test: target pressure-ah minute 1 chhung tlan; GPM (US) emaw L/min (metric) emaw teh a ni.

3. I unit nena inmil formula hmang rawh:

Imperial (nozzle pakhat, broadcast swath feet-a chhut): GPA = (495 × GPM) / (MPH × W_ft) Metric (nozzle pakhat, broadcast swath meter-a chhut): L/ha = (600 × L/min) / (km/h × W_m)

5) Pattern leh coverage finfiahna

5.1 Pattern test awlsam tak

• Swath sir zawng zawngah tui sensitive paper emaw, tray thuk lo emaw dah rawh.

• Hnathawh san zawng leh chaknaah spray rawh.

• Uniform deposit leh overlap awm leh awm loh enfiah; height/angle siamrem emaw, a tul angin nozzle thlak emaw.

5.2 Dilna hrang hranga coverage enfiah

• Herbicides:  uniformity leh drift control → medium to coarse droplets te dah pawimawh ber.

• Fungicides/Insecticides:  hnah khuh duh → medium to fine droplets.

• Foliar feed:  a hring hring (moderate droplets) a awm a; pH leh tui quality control.

6) Hna hrang hranga nozzle dik thlan

6.1 Thutlukna siam thuai theihna matrix

• Thli tleh, drift‐sensitive: boruak‐induction flat fan; boom hniam zawk; PSI hniam lam a ni.

• Dense foliage/vertical: twin‐fan emaw, hollow cone emaw a ni thei; confirm rate leh PPE a ni.

• Open turf broadcast: standard/low‐drift flat fan hmanga tihchhuah a ni a; 110° a ni a; overlap tih finfiah rawh.

• Fence line / bank hrang hrang: deflector/boomless; swath finfiah rawh; edge hrang hrangte tan speed tihhniam.

• Liquid fertilizer: tui luang chhuak tur tips; kangmei chhuahna pumpelh rawh; pans hmangin rate confirm rawh.

6.2 Angle & size picks (rules of thumb) te chu a hnuaia mi ang hian a ni.

• Manageable boom san zawng nena inmil tur angle thlang rawh.

• PSI tam lutuk lovin rate sang zawk atan nozzle orifice upsize rawh.

• Coverage a tlem chuan PSI tihtlem emaw tihsan emaw (mind drift).

7) Enkawlna: tihfai, enfiah, leh thlak

• Filter & strainers: mesh leh nozzle size inmil; hna apiang zawhah fai.

• Nozzle wear: spec atanga flow ~10% a san chuan set angin thlak leh tur a ni.

• Hrisel taka tihfai: soak leh soft‐brush; pin leh wire te chu pumpelh rawh.

• Spare set rotation: field chhunga swap turin spare set thianghlim tak vawng reng tur a ni.

8) Safety & compliance chungchang

• Droplet size leh tui volume hriat duh chuan label-a tarlan angin zawm tur a ni.

• Buffer zone leh thli threshold zah tur; window lum, vawt, thli tleh te chu pumpelh rawh.

• PPE dik tak hmang rawh; tualchhung dan angin rinseate chu flush leh paih tur a ni.

• Maintenance log leh calibration record te vawng reng tur a ni.

• Coverage atan PSI cranking → orifice lian zawk emaw angle danglam zawk emaw hmang la.

• Boom sang lutuk → drift a tipung a, uneven overlap a tipung bawk.

• Walk speed ngaihthah → operator tin leh load tin tan recalibrate.

• Wire hmanga tihfai → tips a tichhia; soak + soft brush hmang zawk rawh.

• Mesh dik lo → riltam lutuk a luang chhuak; too coarse chuan clogs a phalsak.
