10 principles of air compressor selection
Air compressor is the basic product of industrial modernization. Air compressor is to provide air source power. It is the main body of electromechanical bleed air source device, which is the core equipment of pneumatic system. It converts the mechanical energy of prime mover (usually electric motor) into gas pressure The energy device is the pressure generating device of compressed air. Next, the editor of okmarts.com will introduce you to the 10 principles of air compressor selection. I hope it will help you!
10 principles of air compressor selection
1. Compressed air use.
2. The lowest operating pressure.
3. The demand air volume at the tip and off the peak. If the difference between the highest and lowest operating pressure reaches 3bar, you must consider the "high and low pressure split", and then choose different types of air compressors according to the changes in the peak and off-peak burdens, such as "base load" using centrifugal type (single machine> 75CMM) or snail
Rotary type (single machine <60CMM): "Variable load" uses a high-pressure air machine and a large air tank to respond.
4. Choose and configure different types and grades of dryers and precision filters according to different gas quality. Too good quality wastes energy, and insufficient quality affects the manufacturing process, which must be carefully considered.
5. The control technology of the air compressor is changing with each passing day. The technologies such as "multi-machine interlocking", "variable frequency transmission" and "remote monitoring" can effectively suppress the waste of centrifugal BOV and spiral empty vehicles (saving electricity costs by 25-40%) , Reduce the capacity and investment of standby machine (15-30%), stable
air supply pressure (plus or minus 0.1 bar).
6. The operating efficiency cannot only be compared with the nominal horsepower and air volume in the catalog, but the focus is on the actual "performance curve" and "air volume per horse".
7. The installation considers the size of the computer room space. Ventilation conditions, noise isolation, waste heat, waste water recycling, etc. all lead to the use of energy. In addition, "centralized" has lower installation, maintenance and control costs than "distributed", and can also reduce peripheral equipment. Regional market 8. As for the cooling method, there are air cooling and water cooling. Air cooling does not require additional investment in cooling tower rainwater, but it must have good ventilation: water cooling is that the operating temperature is not affected by the environment, which is beneficial to the life of the air compressor. Only the shortcomings of icing burst and blockage.
9. The stability of the power supply planning voltage demand and voltage drop must be required. The centrifuge is usually high voltage and cannot be moved at all. It will cause an impact on the power grid when starting, and it should be kept in regular operation.
10. The maintenance room must have proper maintenance space and necessary lifting facilities and access channels. Engineering personnel and maintenance should also be given different professional maintenance training.

About the role of screw air compressor inverse proportional valve
The inverse ratio valve is used in conjunction with the disc air intake control. When the system pressure increases due to the decrease in air consumption and reaches the set pressure of the inverse ratio valve, the inverse ratio valve acts and reduces the control air output.

Advantages of air compressor equipped with permanent magnet synchronous motor
1. High efficiency The high efficiency mentioned here does not only mean that the efficiency of the rated power point is higher than that of the ordinary three-phase asynchronous frequency modulation motor, but refers to its average efficiency in the entire speed range. The excitation field of the permanent magnet synchronous motor is provided by the permanent magnet.

Air compressor installation rules
1.Installation The selection of the installation site is most ignored by the staff. Often after the compressor is purchased, it is randomly located and used immediately after piping. There is no prior planning at all. Little did they know that such a sloppy result would cause future compressor failure and maintenance difficulties and poor compressed air quality.

Air compressor lubricant performance requirements
1. High quality base oil The base oil of compressor oil can be divided into two categories: mineral oil type and synthetic oil type. The production of mineral oil-type compressor oil is generally obtained by solvent refining, solvent dewaxing, hydrogenation or clay supplement refining to obtain the base oil, and then add a variety of additives to blend.

Analysis of common problems of air compressor oil filter
1.The perforation problem at the bottom of the oil filter The bottom of the oil filter is perforated, except for a few because the steel plate has blisters, but more because of the material problem of the shell steel. Whether the bottom is easy to perforate is related to the thickness of the shell, but it is not the main reason. When the material of the steel is not good

Analysis of the principle of pneumatic energy saving in air compressor system
Analysis of the principle of "pneumatic energy saving" in air compressor system Basic principle: reducing air consumption is saving energy In the industrial field, compressed air is one of the most common energy sources used in the production process, and air compressors are like refrigerators everywhere in the house. The difference between it and the refrigerator is that the former is "pneumatic" and the latter is "electric." For pneumatic systems, reducing air consumption means saving energy.
