Spray Tool Parts

Spray tools, encompassing a wide range of devices for applying liquids in a dispersed form, rely on various components to function effectively. These parts can be categorized by their role in the overall spraying process: fluid handling, atomization, and control.

Fluid Handling

These parts manage the movement of the liquid from the source to the nozzle.

• Tank/Container: Holds the liquid to be sprayed. Materials vary based on the liquid; plastics for water-based paints, stainless steel for solvents, etc.
• Pump: Generates pressure to move the liquid. Types include:
  • Diaphragm Pumps: Commonly used in low to medium-pressure applications.
  • Piston Pumps: Deliver high pressure, suitable for thicker materials.
  • Gear Pumps: Provide consistent flow, often used for oils and viscous fluids.
  • Syphon Feed: Uses air pressure to draw liquid from a container.
• Hoses/Tubing: Connect the tank to the pump and the pump to the spray gun. Materials must be chemically resistant to the liquid.
• Filters: Remove particles from the liquid to prevent nozzle clogging.

Atomization

These parts break the liquid into fine droplets for application.

• Nozzle: The critical component responsible for shaping and dispersing the liquid. Various nozzle types exist:
  • Fan Nozzles: Produce a flat, wide spray pattern.
  • Cone Nozzles: Generate a circular spray pattern.
  • Hollow Cone Nozzles: Create a ring-shaped spray pattern.
  • Flat Stream Nozzles: Deliver a concentrated, linear spray.
  • Air Atomizing Nozzles: Use compressed air to break the liquid into very fine droplets, ideal for coatings.
  • Electrostatic Nozzles: Charge the droplets for improved wrap-around and reduced overspray.
• Atomization Chamber: The area where the liquid is broken down. Design influences spray quality and pattern.

Control

These parts regulate the spraying process.

• Trigger/Valve: Controls the flow of liquid.
• Pressure Regulator: Maintains consistent pressure.
• Adjustable Knobs/Dials: Control spray pattern, flow rate, and pressure.
• Gauges: Display pressure readings.
• Safety Mechanisms: Including pressure relief valves and trigger locks.

Common Types of Spray Tools & Associated Parts

• Airless Sprayers: Utilize high pressure to atomize the liquid directly. Parts include a high-pressure pump, airless nozzle, and high-pressure hoses.
• HVLP (High Volume Low Pressure) Sprayers: Rely on a large volume of air at lower pressure. Parts include an air compressor, HVLP nozzle, air cap, and fluid cup.
• LVLP (Low Volume Low Pressure) Sprayers: Similar to HVLP but require less compressed air.
• Electrostatic Sprayers: Utilize an electrical charge to wrap the coating around surfaces. Parts include an electrostatic nozzle, grounding clip, and power supply.
• Handheld Sprayers: Typically use a manual pump or compressed air canister.
• Garden Sprayers: Used for applying fertilizers, pesticides, and herbicides. Parts include a tank, pump handle, nozzle, and wand.

The specific parts and their materials depend heavily on the application, the type of liquid being sprayed, and the desired spray quality. Regular maintenance and replacement of worn parts are crucial for optimal performance and safety.

Based on the provided information, “spray tool parts” can be classified as follows:

• 8424900500: Parts of fire extinguishers. This HS code covers parts specifically for fire extinguishers.
• 8424900500: Mechanical appliances (whether or not hand operated) for projecting, dispersing or spraying liquids or powders; fire extinguishers, whether or not charged; spray guns and similar appliances; steam or sand blasting machines and similar jet projecting machines; parts thereof: Parts: Of fire extinguishers. This code includes parts for spray guns and similar appliances.
• 8487900080: Machinery parts, not containing electrical connectors, insulators, coils, contacts or other electrical features, and not specified or included elsewhere in this chapter: Other Other. This code is applicable to general machinery parts that do not have electrical components and are not specifically categorized elsewhere.

Regarding HS code 8424900500, it is important to note that this code specifically applies to parts of fire extinguishers. If the parts are for other types of spray tools (e.g., spray guns), HS code 8424900500 may not be appropriate.

Regarding HS code 8487900080, please note that this code covers a broad range of machinery parts. It is crucial to ensure that the parts do not contain any electrical components (connectors, insulators, coils, contacts) and are not specifically classified under another chapter.
