Selection of Screw Oil-free Air Compressor

According to the industry to choose oil-free air compressor, not only to consider the air compressor, air compression station investment, operating costs, operating costs and other comprehensive technical and economic indicators, but also to consider whether the air compressor in line with environmental protection, stable and reliable, excellent production quality principle. Overall, I have summarized the following points:

1. The air compressor must meet the hard core requirements of the flow value and pressure value required in the production process. The working environment of the air compressor is usually required to be kept within the high energy efficiency range, which can save a lot of unnecessary power supply, and it is not easy to damage the components and cause unnecessary losses.

2. The air compressor you choose must be small in size, light in weight, reasonable in price, high in energy efficiency, and environmentally friendly emissions.

Low noise, stable operation and long service life.

3, simple structure, convenient operation, easy to buy accessories;

4. What is the estimated cost of purchasing the air compressor project for the selected air compressor unit station and whether it is more energy-saving.

Obviously, when choosing an air compressor, it is mainly based on the working pressure and flow rate of the starting system. The working pressure of the air source should be higher than the z large working pressure of the pneumatic system, because this is related to the loss and local loss of the gas pipeline. If the system is running when it is required, the working pressure requirements of some places are low, the pressure reducing valve can be used. The discharge pressure of the air compressor is divided into low pressure, medium pressure, high pressure) and ultra-high pressure or above. You can choose different discharge pressures according to your actual needs. Usually low pressure between 0.7 ~ 1.25Mpa. There are still many demands in the industry, which can be considered as appropriate.

Next, the choice of oil-free air compressor is introduced:

understand the air characteristics, local atmospheric pressure and local air relative humidity will affect the use of air compressors.

2. The diameter and content of solid dust particles in the air are also a point that needs attention, which is related to the use temperature of the later equipment.

3, and the required flow. We are often referred to as air flow. Exhaust volume refers to the air compressor in the specified exhaust pressure per unit time can be discharged gas statistics, and finally reach the amount of intake state.

4. Unit flow rate: m & sup3;/min (m3/min);

5. Considering the large working pressure of z, it depends on the pressure requirements of the air compressor you buy.

In addition, when determining the volume flow of the oil-free air compressor, it is necessary to understand the total volume flow of the gas equipment. Most people do not know how to calculate it. They can consult the selection technicians and make appropriate selection to avoid waste. It is good for users and air compressor equipment.
