The selection of air compressors has a great relationship with the industry. The first thing to consider is the scale of production, the second is the capital budget, and the third is the use of site, environment and other factors. Many industries operate air compressors 24 hours a day, and the energy consumption costs of these industries will be relatively high. At this time, choosing a frequency conversion air compressor can effectively reduce costs. Generally speaking, users need to choose the air compressor model according to local conditions. Today, the editor will introduce to you how to choose the air compressor model that suits you in the sandblasting machine industry.
How to choose:
1. Determination of air volume
Reasonable determination of air consumption should consider pipeline leakage and the air used for blowing off the dryer, the air used for back blowing of the dust blasting machine and the air used by other equipment. Large selection of air volume will increase equipment and power investment, and small selection will result in air pressure not reaching the rated pressure, and the sandblasting machine and other equipment cannot be used normally. Generally, a margin of 10% is required.
2. Work pressure
First determine the air pressure of all equipment, select the highest air pressure of the equipment, and then select the air compressor. If the equipment is of different air pressure, connect the equipment with the highest air pressure first, and then connect in order according to the pressure of each device. Demand, use a pressure reducing valve in the connection to meet the pressure requirements of each device. The higher the pressure, the greater the power consumption. If the equipment requires a large pressure difference, it is better to choose a different air compressor to use, which can reduce the cost.
3. Reasonable air compressor quality requirements
Oil content requirements: different oil removal filter combinations can be selected to meet the requirements. Water content requirements: a refrigerated dryer can be used when choosing a sandblasting machine. Dust content requirements: different dust removal filter combiners can be selected according to the site environment to meet the requirements. Based on the principle of sufficient use, do not blindly improve quality to increase the purchase cost of equipment.
4. Model selection of air compressor
The advantages of the piston air compressor: the widest range of adaptable pressure, high pressure must be selected, low equipment price, highest efficiency, small displacement with exhaust pressure, and strong maintainability. Disadvantages: complex structure, many wearing parts, large maintenance workload, average reliability, large size, large vibration and noise. The advantages of screw air compressors: strong reliability, convenient operation and maintenance, good power balance, low noise and vibration, large displacement, small size, and can save floor space. Disadvantages: After long-term operation, the screw gap becomes larger, the displacement becomes smaller, the maintainability is poor, and the regular maintenance costs are high.
The above are a few basic methods for the selection of the sandblasting machine industry. In addition, for special circumstances and needs, it is better to find a professional engineer to check and calculate on the spot.
