4. SPRAYERS AND IT’S COMPONENTS
SPRAYER
• A SPRAYER IS A DEVICE USED TO SPRAY A LIQUID, WHERE SPRAYERS ARE
COMMONLY USED FOR PROJECTION OF WATER, WEED KILLERS, CROP
PERFORMANCE MATERIALS, PEST MAINTENANCE CHEMICALS, AS WELL AS
MANUFACTURING AND PRODUCTION LINE INGREDIENTS

6. BASIC COMPONENTS OF SPRAYERS
• NOZZLE BODY: MAIN COMPONENT ON WHICH OTHER COMPONENTS OF NOZZLE FIT.
• SWIRL PLATE: IT IS A PART OF CONE NOZZLE WHICH IMPARTS ROTATION TO LIQUID PASSING THROUGH IT.
• NOZZLE DISC: COMPONENT CONTAINING THE FINAL ORIFICE OF NOZZLE USUALLY IN CONE NOZZLE.
• NOZZLE CAP: COMPONENT WHICH RETAINS THE ASSEMBLED PARTS IN OR ON A NOZZLE BODY. THE NOZZLE
DISC OR TIP MAY BE INTEGRAL WITH THE CAP.
• SPRAY GUN: IT IS A LANCE FROM WHICH THE SPRAY IS READILY ADJUSTABLE DURING THE OPERATION.
• SPRAY BOOM: IT IS SPRAY LANCE WITH SPRAY NOZZLES FITTED TO A HEAD MOUNTED AT RIGHT ANGLE TO
THE LANCE.
• FILTER: COMPONENT TO REMOVE SUSPENDED MATTER LARGER THAN A PRE-DETERMINED SIZE FROM FLUID.
• OVER-FLOW PIPE: IT IS A CONDUIT THROUGH WHICH EXCESS FLUID FROM A PUMP IS BY-PASSED BY THE
ACTION OF RELIEF VALUE OR PRESSURE REGULATOR.

7. BASIC COMPONENTS OF SPRAYERS
• RELIEF-VALUE: IT IS AN AUTOMATIC DEVICE WHICH OPENS WHEN THE PRESSURE OF FLUID OR GAS REACHES A PRE-DETERMINED VALUE.
•
• PRESSURE REGULATOR: IT IS AN AUTOMATIC DEVICE TO CONTROL THE PRESSURE OF FLUID OR GAS WITHIN A RANGE OF SETTINGS.
•
• CUT-OFF VALUE: IT IS MECHANISM BETWEEN PUMP AND NOZZLE TO CONTROL THE FLOW OF LIQUID FROM SPRAYER. IT IS OPERATED BY HAND.
•
• NOZZLE BOSS: IT IS A LUG ON SPRAY BOOM OR SPRAY LANCE TO WHICH A NOZZLE BODY OR CAP IS SCREWED.
•
• NOZZLE TIP: IT IS THE COMPONENT CONTAINING FINAL ORIFICE OF NOZZLE USUALLY A FAN NOZZLE.
•
• SPRAY LANCE: A HAND-HELD PIPE THROUGH WHICH LIQUID REACHES THE NOZZLE MOUNTED AT FREE END.
