• What should I know before choosing to use pneumatic tools?

  air tools also have their drawbacks when they are used. First, they require the use of air hoses to provide air to provide power. This means that the point power cord for pneumatic tools will be thicker, heavier and less flexible than power tools. However, the coiled air hose can improve this situation. The coiled air hose can make the pneumatic tool more convenient, which is very suitable for low-power desktop tools. Second, the air inlet of the pneumatic tool needs to be lubricated frequently. The air sent into the tool must be filtered and lubricated to prevent premature wear of the pneumatic tool, and maintenance and repair are more troublesome. Third, pneumatic tools may generate more noise when they are used. This is because the air is discharged from the exhaust port on the tool, and this process generates some noise. Most importantly, the cost of pneumatic tools is generally higher than pneumatic tools. First of all, the price of pneumatic tools themselves is higher; second, the use of pneumatic tools necessarily uses air compressor, which increases the cost of using pneumatic tools to a certain extent.
• How to operate sprayer

  First, you should choose the right nozzle. There is a hole in the front of the airless paint sprayer. Most paint sprayers have interchangeable spray heads. They have a simple numbering system. Before spraying, you need to choose a spray head with a suitable spray width and opening size. It should be noted that the nozzle may wear out after use. The severity of the abrasion depends on the grit of the paint, the quality of the materials used, the pressure used, or the frequency of cleaning the nozzle. Pay attention to the applied pressure and avoid excessive spraying, which can effectively extend the service life of the nozzle. When using the sprayer for the first time, it is recommended to practice in the old newspaper for a period of time. The spray head of the sprayer should not be too far away from the wall to ensure the finish of the wall after painting. If the spray head is too close to the wall, the sprayed pattern may be too large. When spraying with a sprayer, it is necessary to maintain the level of the spray head. During the movement of the hand, it is necessary to ensure that it operates at a stable speed. Then pull the trigger to start spraying from a lighter color. After spraying the first layer of paint, you need to wait a few hours for the paint to dry completely before spraying the second layer of paint. After spraying, pour excess paint back into the paint tank and clean the electric paint sprayer. Refill the hopper of the sprayer with water or thinner, clean and wipe.
• The scope of application of different types of spraying machine

  There are currently two basic types of sprayers on the market, one is an airless paint sprayer, and the other is an air-driven sprayer. These two spraying machines are suitable for different types of paint. Most of the small and exquisite hand-held paint sprayers have some form of pump inside, so they are actually a miniature airless sprayer. These miniature handheld sprayers are also called spray guns. Such sprayer is very suitable for spraying in those narrow areas. At the same time, the spray gun is small and light, which is convenient for users to carry. The HVLP spraying machine, also known as a cordless spraying machine, can spray paint in both horizontal and vertical directions with the help of a rotating cover, and can complete a good quality nozzle operation within a few minutes. This type of spraying machine is most suitable for spraying larger projects such as houses, boats, and fences. Because it does not have wires, it is more convenient during transportation. Some cordless sprayers usually have automatic China spray gun, which can reduce the loss of manpower.
• How powerful is the airsoft?

  As the representative of the oldest air tools, the earliest air guns can be traced back to 1580, when air guns used air pumps rather than air compressors to compress air. Although the design of the early air guns was far inferior to today's air guns, the shooting speed of the air gun projectiles could have reached 200-300 meters per second at that time, which was extremely amazing. The biggest difference between air guns and common firearms is that the kinetic energy source of the projectile is different. Firearms rely on the high-energy expansion gas generated by the intense combustion of propellant and other propellants to push the projectile. The energy comes from the chemical exothermic reaction. The air gun uses the gas pressurized by the air pump to eject the projectile, so the gas pressure generated by the air gun is much lower than that of the firearm, and the power of the air gun is usually weaker than that of the firearm. Although the power of air guns is weaker than that of firearms, early air guns generally appeared on the battlefield due to their greater power, no flash, no smoke, and their ability to be used on rainy days. Nowadays, some powerful air rifle bullets can even reach 330 meters per second. Many national firearms regulations restrict this type of air rifle. China air gun can actually cause fatal harm to people or animals. Perhaps the airsoft bullets hit the torso and will not cause fatal injuries, but once they hit the head or other important organs and tissues, it is basically difficult to rescue them, too.
• Pneumatic tools that play an important role in car repair

  air tools have many advantages. One of the most important advantages is that compared with electric tools, pneumatic tools have lower torque and higher speed due to inertia. Pneumatic tools are also more compact and easy to carry and use. At the same time, almost all power tools have pneumatic versions, which means that almost all problems that should be solved by power tools can be solved with pneumatic tools. To use an air wrench as an example, in the process of car repair, it is more convenient to use a pneumatic wrench than a traditional wrench, and it can save more time. This is because pneumatic wrenches have original power compared to manual wrenches; at the same time, they are smaller than electric wrenches and are more suitable for use in narrow spaces under the car or its hood, which is extremely important in car repairs. Common pneumatic tools are China air gun, pneumatic wrenches, pneumatic drills, etc.
• Classification of spray gun

  The China spray gun is a device that uses liquid or compressed air to quickly release as power. The spray gun is divided into two types: general pressure type and pressurized type. Spray guns also include pressure spray guns, carle spray guns, and automatic recovery spray guns. The spray gun includes a gun body and a gun head, and the gun body and the gun head are connected by a connecting mechanism; the gun head includes a nozzle, and a number of metal round steels are welded inside the nozzle; the connecting mechanism includes a flange and a chain pin, The nozzle is made flat; its replacement is more convenient, the cost is lower, and it can effectively prevent the tip of the gun from falling off and wearing away. The application of the spray gun in the industry can be directly loaded with paint, that is, the simple spray gun can be installed in automatic equipment such as automatic glue spraying machine, automatic glue spreading machine, electric paint sprayer, coating machine and other spraying equipment.
