Pneumatic Spray Gun With High Flow and Low Pressure

Product Description

H-827 H.V.L.P.

I. Core Models and Basic Characteristics

The H-827 series spray gun is a pneumatic HVLP (high flow and low pressure) spraying tool, suitable for efficient spraying in fields such as automobiles, furniture, and industry. The main models include:

Nozzle specifications: 1.4mm, 1.7mm, 2.0mm, 2.5mm (Supporting different coating viscosities)

Material: The gun body is made of aluminum alloy, the air cap is made of brass, and the nozzle tip is made of stainless steel. It is durable and corrosion-resistant.

Capacity: 600ml gravity feeding cup, suitable for continuous operation.

Working pressure: 3-4bar (optimal working range), air consumption: 2-5CFM.

Ii. Technical Parameters and Functional Highlights

Applicable scenarios: Car touch-up painting, furniture surface spraying, industrial coating (such as photocatalyst, chemical spray).

Spraying efficiency: Supports approximately 5,000 spraying tasks per day (depending on the specific model).

Adjustment function: Equipped with three-direction adjustment knobs for air volume, paint output, and spray area, it precisely controls the atomization effect.

Compatibility: Supports OEM/ODM customization and can be adapted to different types of coatings (such as primers, topcoats, and high-viscosity coatings).

Iv. Key Points for Use and Maintenance

1.Operating norms

When spraying, keep the spray gun vertical, about 200mm away from the surface, and move it at a constant speed to avoid sagging.

Before use, check the sealing performance of the needle valve and gasket to prevent air and paint leakage.

2.Daily maintenance

Cleaning: Clean the paint passage immediately after each use to prevent blockage (especially for two-component paints).

Lubrication: Regularly apply lubricating oil to components such as ejector pins and springs to prevent rust and ensure the flexibility of moving parts.

Storage: When not in use for a short time, the tip of the gun can be immersed in the solvent, but avoid soaking the entire gun to prevent damage to the sealing ring.

V. Purchasing Suggestions

Automobile maintenance/small-batch operations: BSS H-827 is recommended (with high cost performance).

Industrial high-frequency use: Select BSS H827 (large-capacity cup, multi-nozzle compatible).

Customized requirements: Give priority to contacting suppliers that support OEM to confirm the sample production cycle and cost.

Customized services: Some models support brand customization (OEM) and accessory matching to meet personalized needs.

FAQS:

Question A: How to correctly adjust the air pressure and spray mode of the H-827 spray gun?

Answer A:Air pressure adjustment of H-827 spray gun

1.Connect the air source: Connect the spray gun to the air compressor through the air pipe, ensuring a secure connection. Then, turn on the compressor and adjust the output air pressure.

2.Initial adjustment: Generally speaking, the working air pressure of the H-827 spray gun is around 2-3.5 bar. The output air pressure of the compressor can be adjusted to around 3 bar first.

3.Fine adjustment: Gently press the trigger of the spray gun to let the air spray out and observe the ejection of the spray gun. If the jet is too rapid, the air pressure can be appropriately reduced. If the jet is weak, the high air pressure can be slightly adjusted, and at the same time, adjustments can be made in combination with the actual spraying effect.

Adjustment of the spray mode of the H-827 spray gun

1.Circular spray mode: Usually, the default installation method of the nozzle of the spray gun will produce a circular spray mode, which is suitable for smaller areas that require concentrated spraying, such as repair work.

2.Fan-shaped spray mode: To adjust to the fan-shaped spray mode, rotate the fan-shaped adjustment knob on the spray gun. Generally, clockwise rotation can make the sector Angle smaller, while counterclockwise rotation can make the sector Angle larger. According to the spraying area and shape requirements, adjust the sector Angle to an appropriate size. For example, when spraying a large flat area, the sector Angle can be increased.

During the adjustment process, continuous trial spraying should be carried out. The air pressure and spraying mode should be precisely adjusted based on the atomization effect of the coating, the uniformity of the spraying, and the actual working requirements to achieve the best spraying effect. Meanwhile, different coatings and working scenarios may require different Settings, which need to be adjusted flexibly.

Question B: How to clean and maintain the H-827 spray gun after use?

Answer B:Cleaning of H-827 spray gun

1.Empty the paint can: After use, first pour the remaining paint in the spray gun paint can back into the original container, and try to empty it as completely as possible.

2.Disassemble components: According to the spray gun manual, carefully disassemble the detachable components of the spray gun, such as the nozzle, needle valve, air cap, paint cup, etc.

3.Cleaning components: Soak the disassembled components in a dedicated cleaning solvent and gently scrub them with a soft-bristled brush to remove any residual paint on the surface. Special attention should be paid to cleaning the small holes on the nozzles and air caps to ensure there is no blockage. For stubborn stains, a spray gun cleaning needle can be used to unclog them.

4.Rinsing and drying: Thoroughly rinse the components with a clean solvent, then dry them with a clean towel or compressed air. Be careful to avoid dust contamination.

5.Clean the gun body: Wipe the gun body with a damp cloth to remove surface paint and stains, ensuring that the exterior of the gun body is clean and tidy.

Maintenance of H-827 spray gun

1.Lubrication: Apply an appropriate amount of special spray gun lubricating oil to the moving parts of the spray gun, such as the trigger and needle valve stem, to keep it running smoothly and reduce wear.

2.Inspect components: Regularly check the components of the spray gun to see if there is any wear, damage or looseness. If the nozzle is found to be worn, it should be replaced in time to avoid affecting the spraying effect.

3.Storage: Store the clean and well-maintained spray gun in a dry and well-ventilated place to prevent it from being bumped or corroded. It can be stored in a special storage box or hanger for spray guns.
