Types of Spray Guns commonly used

Abstract: 本文讲述了几种常见的喷枪类型，包括重力喷枪、吸引喷枪、压力喷枪和空气喷枪。重力喷枪易于控制和清洗，但需频繁加涂料；吸引喷枪易于使用和维护，但涂料易漏出；压力喷枪适合大量生产，但成本较高；空气喷枪操作简单，但喷雾效果不如高压喷枪。文章还指出，不同类型的喷枪适用于不同的应用场景，选择时需考虑物料性质、涂装面积和精度要求等因素。

Types of commonly used Spray Guns with Figure 1

Common Spray Guns include the following:

  1. Gravity Spray Gun: A gravity Spray Gun is a Spray Gun in which the paint cup is mounted above the Spray Gun. It has the advantage of being easy to control and clean, the disadvantage of requiring frequent toppings which can lead to fatigue.

  2. Suction gun: The suction gun places the paint cup under the gun and draws the paint into the gun by negative pressure. Its advantage is that it is easy to use and maintain, and its disadvantage is that the paint is easy to leak.

  3. Pressure Spray Gun: A pressure Spray Gun uses a paint can or pail and uses air pressure to push paint into the gun. Its advantage is that it is suitable for mass production, but its disadvantage is that it requires high-pressure gas source and high cost.

  4. Air Spray Guns: Air Spray Guns are Spray Guns that use compressed air to push paint out of the nozzle. Its advantage is that it is easy to operate, and its disadvantage is that the spray effect is not as good as that of a high-pressure Spray Gun.

Different types of Spray Guns are suitable for different application scenarios. Factors such as the nature of the sprayed material, coating area, and accuracy requirements need to be considered when selecting a Spray Gun.
