Spraying processes can be seen everywhere in life, such as the surface of car bodies, hardware and plastic products, etc. The main function is to prevent corrosion. Oil-free screw air compressor is often used to do power source in the spraying process. So the spraying industry has any requirements for air compressors?
Air spraying process, easy to operate, easy to change color, high production efficiency, good atomization effect, can get meticulous high-quality surface spraying. Since the compressed air is in direct contact with the paint, the compressed gas must be dry, clean, oil-free and water-free, so as to spray the quality. Below we will introduce in detail.
1. No impurities on the spraying surface
particle impurities are the natural enemies of spraying, and their presence will affect the appearance quality of the coating film. Especially in the advanced decorative product coating occasions, the paint must be smooth, no particles, bright as a mirror.
2. The spraying surface is free of oil and water
oil or water in compressed air can cause quality defects such as shrinkage, pinholes, bubbles, and pitting. Shrinkage not only affects the appearance quality of the coating film, but also destroys the integrity of the coating film, and cannot be eliminated by general grinding and polishing methods.
3. Constant pressure gas supply
during the spraying construction, the pressure of the compressed air of the screw air compressor must be kept within a certain range of control and cannot fluctuate greatly. If the air pressure is too low, the paint liquid will be insufficiently atomized and the paint film will be uneven. If the air pressure is too high, the paint liquid will be atomized well, but the paint mist will be too fast, resulting in increased paint loss. If the high-pressure air flow is sprayed on the uncured paint film, paint film defects such as pits and small bubbles will easily occur.
It can be seen that the air compressed by the ordinary screw air compressor must be processed before it can be used. The air compressed by an ordinary screw air compressor is a high-temperature gas containing oil, moisture and dust. In order to ensure the qualified rate of spraying, it is generally required that the pressure dew point of the air compressor is not higher than -40 ℃, the impurity is less than 0.5-1μm, and the oil content is not higher than 0.01 mg/m & sup3;.
Of course, the gas consumption of different spray guns is also different. Enterprises can reasonably configure Grantklin oil-free screw air compressor according to the actual situation.
Frequency conversion air compressor for lubricating oil quality requirements are much higher than the frequency air compressor, can not be used according to the standard selection of lubricating oil frequency air compressor. The reasons are as follows: 1. The frequency conversion air compressor is easy to accumulate water at low frequency, and the water resistance of the lubricating oil is much higher than that of the power frequency air compressor;
1. The air compressor shall be operated by designated trained and qualified students, and shall be used only after being guided and inspected by the instructor on the spot. 2. When using, pay attention to check whether the instruments, valves and electrical facilities are normal. sufficient lubricating oil, and
10 kilograms of oil free screw air compressor how much does it cost? contact our company's sales staff, shanghai granklin group to provide you with 10 kilograms of oil free screw air compressor price. Air compressor, as the name implies, the so-called air compressor, refers to the air from a low
(1) To fully meet the gas consumption of gas equipment, the maximum gas consumption should be calculated according to the type and quantity of pneumatic equipment, and the gas consumption that may be increased in the future should be included, and then the air compressor that can meet the gas supply requirements of pneumatic equipment should be selected.
The expenditure of using screw air compressor is divided into two parts, the cost of using energy consumption and the cost of purchasing machines. Buy water-lubricated oil-free air compressor and choose a suitable brand. Shanghai granklin group can be selected for a price. Oil-free screw air compressor factory direct, the price can make you more satisfied. Quality, after-sales nationwide to provide high-quality services.
For oil-free air compressor, most people will think that the air compressor uses air compressor oil during operation and adopts post-processing filtration to remove oil. In fact, this is one of our misunderstandings about oil-free air compressors. Air compressor oil has many functions, including cooling and lubrication. The so-called oil-free air compressor of Granklin air compressor uses water lubrication, and the compressed air is 100% oil-free.
In the air compressor industry, Shanghai granklin group is a positive response, we produce water lubricated single screw air compressor is in line with environmental protection requirements, compressed gas does not contain a drop of lubricating oil. In the market reflected well, in the medical, pharmaceutical, food, chemical and other industries have made excellent results.
View detailsAir compressor is one of the indispensable gas equipment in the production activities of enterprises, which plays a boosting role in the production process. When selecting screw air compressors, we all want to choose brand and good quality machines, so which air compressor is a good product
In the application of some special scenes of compressed gas, we need to use explosion-proof ability of "explosion-proof air compressor", but most people only know "explosion-proof air compressor", but do not know what is "explosion-proof air compressor".
In the field of air compressor, there are not many manufacturers that can use real frequency conversion motors. Shanghai Granklin Group produces water-lubricated variable frequency air compressors. Through the use of permanent magnet motors and variable frequency controllers, it has achieved the effect of energy saving and emission reduction. General frequency conversion means can suppress frequent loading and unloading of equipment, and can also save a lot of power, improve reliability and reduce noise. If the air compressor uses frequency conversion, it can also stabilize the system pressure.
