Oil-free air compressor is a commonly used air compression equipment, and its structural characteristics mainly include the following aspects:
1. Compressor part: The compressor part of oil-free air compressor usually adopts centrifugal or screw structure. Centrifugal compressor produces centrifugal force through high-speed rotation of rotor, and compresses air; Screw compressors compress air through the interaction of two screws. Both structures enable efficient air compression.
2. Cooling system: oil-free air compressor will generate a lot of heat during the compression process, so it is necessary to be equipped with a cooling system to reduce the temperature. There are two common cooling methods: water cooling and air cooling. Water-cooled systems absorb heat back and forth through water, while air-cooled systems expel hot air through fans.
3. Filtration system: In order to avoid damage to the equipment by impurities such as dust and oil in the air, oil-free air compressors are usually configured with filtration systems. The filtration system includes a pre-filter, a main filter and an activated carbon adsorber. The pre-filter is used to filter larger particles of impurities, the main filter is able to filter finer particles, and the activated carbon adsorbers are able to absorb oil and odors in the air.
4. Control system: The control system of oil-free air compressor is used to regulate and monitor the operating status of the equipment. The control system usually includes pressure switch, temperature sensor, electronic controller and so on. Through these sensors and controllers, automatic start and stop, pressure regulation, fault alarm and other functions can be realized.
5. Gas storage tank: oil-free air compressors are usually configured with gas storage tanks for storing compressed air. The gas storage tank can supply a stable air source smoothly to avoid the instability of the air source caused by the intermittent operation of the compressor.
6. Drainage system: The oil-free air compressor will produce a certain amount of condensate during operation, which needs to be discharged through the drainage system. The drainage system usually includes automatic drainage valves and drainage pipes, which can effectively remove condensate and ensure the normal operation of the equipment.
7. Electrical system: The electrical system of oil-free air compressor includes motor, control circuit and other parts. The motor is used to provide the power of the compressor, and the control circuit is used to control the operation and protection of the compressor.
In general, the structural characteristics of oil-free air compressors mainly include compressor parts, cooling systems, filtration systems, control systems, gas storage tanks, drainage systems and electrical systems. These parts work together to achieve efficient, stable and oil-free air compression.
