The Importance of Air Preparation Unit in Dry Sand Oil

Moisture in the air

Moisture is an inevitable product of air compression. The humidity percentage used in the weather report refers to the concentration of water vapor in the external environment, which may be as low as 1 % and a maximum of 95 %. When compressing the air, press it into a more compact space and heat it and include higher percentage vapor. If the air before entering the pot is not cooled, it will cool inside the explosive pot and hose (due to the decrease in the ambient temperature), and the steam will condense to form water droplets.

Moisture may have a devastating effect on the blasting substrate, protective coating, blasting efficiency and equipment itself.

Use sand broadcasting problems in humid air

Compression water can be used for polishing and may have several harmful and expensive effects.

Waste medium: In order to increase the abrasive flow, the operator may kill the pot, thereby increasing internal positive pressure. This may increase the consumption of the abrasive media by 15 % -20 %, thereby increasing the supplementary time and additional cleaning and disposal costs. When using steel or steel mirrors, the demand for dry air is greater, because the abrasive itself may produce flash rust.

Efficiency loss: By suffocating pressure cookers and reduce pushing pressure, the operator explodes under low pressure. The efficiency loss is 1.5 % in the pressure loss per 1PSI.

Media flow: In the dry blasting, dry abrasive flows are much better than humid abrasives, and humid abrasives will be merged and stuck.

Surface preparation problem: Sandblasting steel removes the protective layer on the metal to make it easy to corrode. Compression water in the air can cause the surface to rust and reduce the strength of the substrate.

Fracture of protective coatings: coating manufacturers insist on the surface of no rust to make the coating stick to the surface. The fault of the protective coating can cause surface corrosion and deterioration.

Equipment wear: premature wear caused by water corrosion, sandblasting equipment itself may be damaged. It increases the premature wear of the valve, leading to the stop time, maintenance and maintenance costs.

What is air preparation unit?

Air preparation unit (also known as air preparation unit) is a special equipment, which aims to use compressed air in sand powder equipment. They are usually composed of multiple components, including air filters, regulators and lubricants. They together improve the quality of compressed air and regulate pressure and flow.

In order to ensure the best performance and efficiency of sand broadcast operations, the use of air preparation units is crucial. In this technology blog, we will explore the advantages of using air preparation units during polishing.

The advantages of using air preparation units in sand spraying

Improved air quality: The compressed air used in sand oil may contain impurities, such as water, oil and dust, which may have a negative impact on the performance of sand optical equipment and affect the quality of the finished work piece. The air preparation unit is equipped with high -quality filters to effectively remove these impurities to ensure that it provides clean and dry air for sand powder equipment. This helps prevent the nozzle from blocking the nozzle, reducing abrasive pollution and leading to higher quality surface decoration.

Consistent pressure control: The air preparation unit is equipped with a regulator to accurately control the air pressure provided to the sandblasting equipment. Consistent pressure control is critical to sand broadcast operations because it helps to obtain consistent results and prevent damage to exquisite or sensitive surfaces. Using air preparation units, operators can easily adjust and maintain the required air pressure to ensure consistency and effective sand and blue performance.

Extended equipment life: The use of air preparation units can help extend the life of sandblasting equipment. By removing water, oil and dust from compressed air, prevent these pollutants from entering the air preparation unit of the sandblasting equipment, leading to corrosion, wear and other damage. This helps reduce maintenance costs, stops time and extend the life of sandblasting equipment. In the long run, it can improve productivity and cost.

This reduces the reliability and durability of compressed air equipment and shorten the maintenance interval.

Enhanced operator safety: Sandblasting will generate a large amount of air particles and dust. If inhalation may be harmful to the operator's health. The air preparation unit with a valid filter can help reduce the concentration of air particles and dust
