How to choose a second-hand air compressor

Want to buy a suitable second-hand air compressor, it depends on whether it has economy, reliability and safety. Today, Aijiuku will talk to you about a few tips for buying second-hand air compressors, hoping to help you.

1. Consider the convenience of air compressor maintenance

After the compressor has been running for a period of time, the moving parts will wear out and the efficiency will be reduced. It must be repaired. At this time, a certain amount of maintenance personnel and maintenance parts are required. Therefore, the spare parts of the compressor should be easily available, and the area where the compressor is used should have corresponding maintenance technicians.

The spare parts of imported air compressors have a long cycle and are expensive. Air compressors are changed quickly, often because the original parts are not available, or because the parts are expensive, and the purchase is abandoned, or because there are no qualified maintenance technicians, the compressor is damaged and cannot be repaired and left idle. Therefore, the convenience of maintenance must be considered when purchasing an air compressor.

2. Consider the gas occasion and conditions

If the gas space is narrow, vertical type should be selected; if there is a long-distance change (more than 300~500 meters) in the gas usage occasion, mobile type should be considered; if the occasion cannot be used for power supply, the diesel engine-driven type should be selected; if the occasion is used If there is no tap water, you must choose the air-cooled type.

3. Consider the level of exhaust pressure and the size of the exhaust

Exhaust volume is one of the main parameters of an air compressor. The air volume of an air compressor should be selected to match the required exhaust volume. If the air consumption is large and the air compressor has a small exhaust volume, the air-driven tool will greatly reduce the exhaust pressure of the air compressor, and the air-driven tool cannot be driven.

Of course, blindly pursuing a large displacement is also wrong, because the larger the displacement, the larger the motor the compressor is equipped with. Not only is the price higher, but it also wastes purchase funds and also wastes electric energy when used.

The above content is a detailed introduction to the purchasing skills of second-hand air compressors, and I hope it will be helpful to everyone. If you want to know more about second-hand equipment, you might as well pay attention to jiuku.
