The nozzle and filter of a high-pressure china airless paint sprayer are crucial components that determine the spray effect. Selecting the right nozzle and filter can improve work efficiency and spray quality. Here are the detailed points and parameters for making the right choice
Selecting the Nozzle Based on Paint Viscosity
Orifice Size
- For low-viscosity materials such as varnish, use a 0.011-0.013 inch orifice.
- For medium-viscosity materials like paint, use a 0.015-0.017 inch orifice.
- For high-viscosity materials such as latex paint, use a 0.019-0.023 inch orifice.
Nozzle Model
For example, a Graco 515 nozzle indicates a spray angle of 50 degrees and an orifice size of 0.015 inches. Using Graco airless sprayer parts ensures compatibility and performance.
Choosing the Appropriate Spray Angle
Spray Angle:
Common angles include 10 degrees, 20 degrees, 30 degrees, etc. A wide angle is suitable for large areas, while a narrow angle is better for details and edge work.
Selecting the Filter
Filter Mesh Size
- Fine filters (such as 200 mesh) are suitable for low-viscosity materials.
- Coarse filters (such as 60 mesh) are suitable for high-viscosity materials. Choosing the right filter can prevent nozzle clogging and ensure smooth paint flow.
Filter Model:
For example, using Graco’s 60 mesh filter for high-viscosity materials, 100 mesh for medium viscosity, and 200 mesh for low-viscosity materials.
Matching Nozzles and Filters
Specification Matching
Ensure the nozzle and filter specifications match to avoid uneven spraying or clogging. For instance, using China made Graco pump parts can help maintain compatibility with your Graco airless sprayer parts.
Regular Replacement
Nozzles and filters are consumable parts and should be replaced regularly based on usage frequency. Generally, nozzles should be replaced after spraying 200-300 liters of paint, and filters should be cleaned after each use and replaced periodically. Using high-quality Graco pump repair parts can also help in maintaining the efficiency of your sprayer.
By carefully selecting and maintaining the appropriate nozzles and filters, your china airless paint sprayer will operate efficiently, providing excellent spray quality and durability.
