定义
A precision-engineered fluid dispensing component designed for agricultural machinery that meters and directs liquid fertilizer into soil with controlled flow rates, spray patterns, and penetration depth. It features calibrated orifice geometry, pressure compensation mechanisms, and anti-clogging design to ensure uniform distribution across varying field conditions.
工作原理
Utilizes Bernoulli's principle and pressure differentials to convert hydraulic energy into controlled kinetic energy. When pressurized liquid fertilizer enters the nozzle chamber, it accelerates through a precisely machined orifice, creating a focused stream or spray pattern. Flow regulation is achieved through adjustable orifice plates or pressure-compensating diaphragms that maintain consistent discharge rates despite pressure fluctuations.
材料
Stainless steel 316L (body)tungsten carbide (orifice insert)PTFE (seals)ceramic (wear surfaces). Corrosion-resistant coatings: electroless nickel plating or DLC coating for abrasive fertilizer formulations.
Flow Rate
0.5-10 L/min @ 3 bar
Spray Angle
15-80 degrees
Orifice Diameter
0.8-3.2 mm
Connection Thread
1/4" NPT or BSPP
Temperature Range
-10°C to 80°C
Operating Pressure
1-8 bar
CV (Flow Coefficient)
0.2-1.8
标准
ISO 10625DIN EN 12701ASABE S572.1

常见问题

What causes nozzle clogging in fertilizer systems?

Clogging typically results from particulate contamination in fertilizer solutions, crystallization of dissolved salts, biological growth, or incompatible chemical reactions. Regular flushing with clean water and using filtered fertilizer solutions prevents most clogging issues.

How often should injection nozzles be replaced?

Replacement intervals depend on operating hours, fertilizer corrosiveness, and maintenance. Typical service life is 500-2000 hours. Inspect monthly for wear patterns, flow rate deviations >10%, or visible damage to orifice surfaces.
