Advantages

√ Simple
One screw rotor and 2 gate rotors which are positioned at right angle to the axis constitute 2 compressing rooms. Therefore, the screw rotor with 6 grooves compresses as many as 12 times per rotation.
√ Quietness
Without applying thrust load to the axis direction of the rotor, the force in the circumference direction rotates quietly with good balance. As a result, the load to the bearing is lightened, minimizing the generation of noise or vibration.
√ Durability
The gate rotors are rotated following the rotation of the screw rotor along its gear. The water film formed on the screw rotor’s gear and the free floating mechanism maintains the high efficiency for a long time (in case of water lubrication).
√ High Efficiency
Since the lubrication water is jetted in the compressing process, the compression is done smoothly under almost even temperature, realizing ideal, safe and highly efficient compression with slow rotation (in case of water lubrication).

What is the impact of humidity on compressed air quality?

Humidity can have a significant impact on the quality of compressed air. Compressed air systems often draw in ambient air, which contains moisture in the form of water vapor. When this air is compressed, the moisture becomes concentrated, leading to potential issues in the compressed air. Here’s an overview of the impact of humidity on compressed air quality:

1. Corrosion:

High humidity in compressed air can contribute to corrosion within the compressed air system. The moisture in the air can react with metal surfaces, leading to rust and corrosion in pipes, tanks, valves, and other components. Corrosion not only weakens the structural integrity of the system but also introduces contaminants into the compressed air, compromising its quality and potentially damaging downstream equipment.

2. Contaminant Carryover:

Humidity in compressed air can cause carryover of contaminants. Water droplets formed due to condensation can carry particulates, oil, and other impurities present in the air. These contaminants can then be transported along with the compressed air, leading to fouling of filters, clogging of pipelines, and potential damage to pneumatic tools, machinery, and processes.

3. Decreased Efficiency of Pneumatic Systems:

Excessive moisture in compressed air can reduce the efficiency of pneumatic systems. Water droplets can obstruct or block the flow of air, leading to decreased performance of pneumatic tools and equipment. Moisture can also cause problems in control valves, actuators, and other pneumatic devices, affecting their responsiveness and accuracy.

4. Product Contamination:

In industries where compressed air comes into direct contact with products or processes, high humidity can result in product contamination. Moisture in compressed air can mix with sensitive products, leading to quality issues, spoilage, or even health hazards in industries such as food and beverage, pharmaceuticals, and electronics manufacturing.

5. Increased Maintenance Requirements:

Humidity in compressed air can increase the maintenance requirements of a compressed air system. Moisture can accumulate in filters, separators, and other air treatment components, necessitating frequent replacement or cleaning. Excessive moisture can also lead to the growth of bacteria, fungus, and mold within the system, requiring additional cleaning and maintenance efforts.

6. Adverse Effects on Instrumentation:

Humidity can adversely affect instrumentation and control systems that rely on compressed air. Moisture can disrupt the accuracy and reliability of pressure sensors, flow meters, and other pneumatic instruments, leading to incorrect measurements and control signals.

To mitigate the impact of humidity on compressed air quality, various air treatment equipment is employed, including air dryers, moisture separators, and filters. These devices help remove moisture from the compressed air, ensuring that the air supplied is dry and of high quality for the intended applications.

How are air compressors utilized in pneumatic tools?

Air compressors play a crucial role in powering and operating pneumatic tools. Here’s a detailed explanation of how air compressors are utilized in pneumatic tools:

Power Source:

Pneumatic tools rely on compressed air as their power source. The air compressor generates and stores compressed air, which is then delivered to the pneumatic tool through a hose or piping system. The compressed air provides the force necessary for the tool to perform various tasks.

Air Pressure Regulation:

Air compressors are equipped with pressure regulation systems to control the output pressure of the compressed air. Different pneumatic tools require different air pressure levels to operate optimally. The air compressor’s pressure regulator allows users to adjust the output pressure according to the specific requirements of the pneumatic tool being used.

Air Volume and Flow:

Air compressors provide a continuous supply of compressed air, ensuring a consistent air volume and flow rate for pneumatic tools. The air volume is typically measured in cubic feet per minute (CFM) and determines the tool’s performance capabilities. Higher CFM ratings indicate that the pneumatic tool can deliver more power and operate at a faster rate.

Tool Actuation:

Pneumatic tools utilize compressed air to actuate their mechanical components. For example, an air-powered impact wrench uses compressed air to drive the tool’s internal hammer mechanism, generating high torque for fastening or loosening bolts and nuts. Similarly, air-powered drills, sanders, nail guns, and spray guns rely on compressed air to power their respective operations.

Versatility:

One of the significant advantages of pneumatic tools is their versatility, and air compressors enable this flexibility. A single air compressor can power a wide range of pneumatic tools, eliminating the need for separate power sources for each tool. This makes pneumatic tools a popular choice in various industries, such as automotive, construction, manufacturing, and woodworking.

Portability:

Air compressors come in different sizes and configurations, offering varying degrees of portability. Smaller portable air compressors are commonly used in applications where mobility is essential, such as construction sites or remote locations. The portability of air compressors allows pneumatic tools to be used in various work environments without the constraints of being tethered to a fixed power source.

Overall, air compressors are integral to the functionality and operation of pneumatic tools. They provide the necessary power, air pressure regulation, and continuous airflow required for pneumatic tools to perform a wide range of tasks efficiently and effectively.
