Following are some types of precision air compressors according to working principle:
Positive Displacement Compressors
Positive displacement precision air compressors work by decreasing the volume of a chamber to increase the pressure of the air inside that chamber. Then the pressurized air gets discharged into the pipeline system. This type of compressor has two main kinds:
Screw Air Compressors
Screw air precision compressors are designed with two large screws that rotate in opposite directions to compress the air. They combine compression elements into a compact housing and are more efficient for industrial applications.
Scroll Air Compressors
Scroll precision air compressors use two spiral-shaped scrolls to compress the air. One stationary scroll and one orbiting scroll move together, trapping, expanding, and compressing the air in the pockets between them. Their compact size and quiet operation make scroll compressors great for small businesses and workshops.
Dynamic Compressors
Dynamic precision compressors work by adding kinetic energy to the air through the rapid spinning of a rotor inside the housing. The fast rotation increases the velocity of airflow and then transforms part of its energy into pressure by the help of the diffuser. This process leads to the compression of air. This type of compressor contains two main models: centrifugal and axial air compressors.
Centrifugal precision air compressors use a rotating wheel to add energy to the air. As the wheel spins faster, it pushes more air out which gets compressed in the housing. An axial air precision compressor changes the direction of air flow using a rotor with blades that look like a propeller. These two designs function well for dynamic precision compression in larger industrial settings where big volumes of compressed air at lower pressures are required.
Temperature Range:
The temperature precision air control system is typically designed to function within a specific temperature range. This range can be as narrow as ±0.1°C or even ±0.01°C, depending on the application and the capabilities of the system.
Humidity Control:
Humidity precision air specifications may involve maintaining moisture levels within a specific range. This could be, for instance, a humidity control capability of ±1% or ±0.5% or even lower or higher limits depending on the particular needs of the application.
Filtration Efficiency:
Filters used in precision air systems are measured based on their capacity to capture and remove specific sizes of particles. This is usually expressed in terms of Minimum Efficiency Reporting Value (MERV) ratings, MPPS (Most Penetrating Particle Size), and DOP (Dispersed Oil Particles) testing. For instance, high-efficiency particulate air (HEPA) filters might have a MERV rating of 17-20, indicating that they remove 99.97% of particles that are 0.3 microns or larger.
Airflow:
The precision air system's airflow or volume is measured in cubic feet per minute (CFM), indicating the amount of air moving through the system per minute. The necessary CFM will depend on the system's size and the building or room's needs where it is installed.
Temperature and Humidity Sensors:
Precision air systems typically use digital sensors for temperature and humidity monitoring. These sensors provide high-accuracy measurement with a typical temperature accuracy of ±0.1°C and a humidity accuracy of ±0.5% or better.
Control System:
Precision control systems usually have many features like programmable logic controllers (PLCs), direct digital control (DDC), touchscreen user interfaces, and web-based remote control and monitoring. In addition, the system may include alarm and notification functions for automatic reporting of malfunction, exceeding the set points, and other specified events.
Power Consumption:
Power consumption of a precision air system, which is usually indicated in kW (kilowatts), depends on the system size and capacity. It is important to calculate the system's energy usage to understand its operating cost and environmental impact.
Regular Inspections:
Conduct planned inspections regularly based on the specified maintenance cycle. During the inspection, carefully check the appearance of precision air pieces, internal structure, and peripheral environment, and pay attention to whether there are signs of water ingress, abnormal temperature changes, mechanical damage, etc. Trouble, record it in a timely manner, and deal with it according to the relevant operating procedures.
Lubricant Replacement:
Replace the lubricating oil and lubricating oil frequently for precision air equipment to ensure good operation and service life. Replace engine oil at intervals in accordance with guidelines. For air, water, and hydrostatic power transmission precision air machinery systems, select lubricants with appropriate viscosity and performance per the equipment requirements. Clean and replace lubricating components, such as oil pumps, filters, and greasing devices, to ensure smooth oil circulation and lubrication.
Fan Maintenance:
If precision air machinery includes a cooling fan, keep its operating condition vigilant. Regularly check the fan blades, hub bearings, and drive belting, etc., to ensure that the fan is efficiently dissipating heat and smoothly driving the precision air machinery to work normally.
Address Water Issues:
If precision air machines are susceptible to humidity or water, take appropriate damp-proof measures, such as using moisture-proof bags, dehumidifiers, sealing, and other methods, to prevent water damage to their internal components.
Document Keeps:
Precision air machine maintenance operations and maintenance records should be kept. This log can be used to audit and track the maintenance work done to ensure that routine maintenance and repairs are performed according to schedule, thus helping to improve the reliability and stability of the equipment.
An air compressor delivers pressurized air precisely, and then businesses use it precisely to meet the needs of various industry applications. Here are some highlights:
Health and Pharmaceutical Industries
These industries use precision air for critical applications such as mass medication delivery, automated pill dispensing, syringe filling, insulin delivery, and respiratory therapy systems. They deliver medications to patients through the air compression method. In automated pill dispensing, precision air systems ensure separately prescribed medicine is not mixed up. This method enhances efficiency and reduces the risk of contamination in syringe filling.
Food and Beverage Industries
When carbonating beverages, inflating packaging, and moving product-filled packages, food, and beverage industries will use precisely filtered, dried, and pressurized air. This method preserves food and beverage products' taste and integrity.
Manufacturing Industries
Manufacturing industries use precision air for material handling, bottle blowing, assembly, and air-driven tools. This method already has a great impact on different industries. Productivity increases due to the efficient assembly of products, including machinery. Air motors drive precision air-compressor-powered tools, reducing energy consumption and carbon emissions.
Printing Industries
Precision air is also popular in the printing industry. Printers use it for printhead cleaning, paper handling, and static elimination during the printing process. Precision air eliminates dust and debris from printheads, ensuring consistent print quality. Paper is precisely compressed air controlled to prevent jams and ensure smooth feeding. Precision air eliminates static electricity, which attracts dust and allows better control of material.
Electronics Industries
In the electronics industry, manufacturers use a direct blow-off method for particle removal, assembling small components on circuit boards, and testing electronic devices. Removing particles using precision air minimizes product defects and improves yield. Air-compressed precision tools allow easy handling of small electronic items without damaging sensitive components.
