The Know-How
More than decades of know-how in manufacturing for the compressed air market. World wide knowledge in different compressed air applications have guided the development of customer specified stationary screw compressors.

Technical Advancement for your Benefit
The advantage of CHINAMFG lies in its simplified construction. Fewer components are utilized. This means a 60% reduction in main and wearing parts and over 70% fewer pipes and connections. In turn, this greatly reduces the risk of leakages, making the system environmentally friendly. Safe direct drive operation without V-belt transmission.

The CHINAMFG CHINAMFG works in the following way:
Ambient air is drawn through the intake filter and the multifunctional control system into the CHINAMFG block. This block consists of a pair of screw rotors. The main rotor, driven by an electric motor, takes the secondary rotor with it. The air is drawn in by the rotation of both of the interlocking rotors and is continually compressed. During rotation, coolant is injected into the rotors and forms a hydrostatic film between the main and secondary rotors. The function of the coolant is to seal the rotors, lubricate the bearings and adsorb the compression heat. Before compressed air leaves the compressor ( at 80 ºC approx.) it is separated from the coolant before being cooled in the aftercooler to approx.. 8ºC to 12ºC above the ambient temperature. The coolant then passes to the thermostatic control block and filter, before entering the cooler where it is cooled from approx.. 80ºC down to 50ºC. It is then injected back into the CHINAMFG block.

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.

What is the difference between a piston and rotary screw compressor?

Piston compressors and rotary screw compressors are two common types of air compressors with distinct differences in their design and operation. Here’s a detailed explanation of the differences between these two compressor types:

1. Operating Principle:

  • Piston Compressors: Piston compressors, also known as reciprocating compressors, use one or more pistons driven by a crankshaft to compress air. The piston moves up and down within a cylinder, creating a vacuum during the intake stroke and compressing the air during the compression stroke.
  • Rotary Screw Compressors: Rotary screw compressors utilize two intermeshing screws (rotors) to compress air. As the male and female screws rotate, the air is trapped between them and gradually compressed as it moves along the screw threads.

2. Compression Method:

  • Piston Compressors: Piston compressors achieve compression through a positive displacement process. The air is drawn into the cylinder and compressed as the piston moves back and forth. The compression is intermittent, occurring in discrete cycles.
  • Rotary Screw Compressors: Rotary screw compressors also employ a positive displacement method. The compression is continuous as the rotating screws create a continuous flow of air and compress it gradually as it moves along the screw threads.

3. Efficiency:

  • Piston Compressors: Piston compressors are known for their high efficiency at lower flow rates and higher pressures. They are well-suited for applications that require intermittent or variable air demand.
  • Rotary Screw Compressors: Rotary screw compressors are highly efficient for continuous operation and are designed to handle higher flow rates. They are often used in applications with a constant or steady air demand.

4. Noise Level:

  • Piston Compressors: Piston compressors tend to generate more noise during operation due to the reciprocating motion of the pistons and valves.
  • Rotary Screw Compressors: Rotary screw compressors are generally quieter in operation compared to piston compressors. The smooth rotation of the screws contributes to reduced noise levels.

5. Maintenance:

  • Piston Compressors: Piston compressors typically require more frequent maintenance due to the higher number of moving parts, such as pistons, valves, and rings.
  • Rotary Screw Compressors: Rotary screw compressors have fewer moving parts, resulting in lower maintenance requirements. They often have longer service intervals and can operate continuously for extended periods without significant maintenance.

6. Size and Portability:

  • Piston Compressors: Piston compressors are available in both smaller portable models and larger stationary units. Portable piston compressors are commonly used in construction, automotive, and DIY applications.
  • Rotary Screw Compressors: Rotary screw compressors are typically larger and more suitable for stationary installations in industrial and commercial settings. They are less commonly used in portable applications.

These are some of the key differences between piston compressors and rotary screw compressors. The choice between the two depends on factors such as required flow rate, pressure, duty cycle, efficiency, noise level, maintenance needs, and specific application requirements.
