Several common classification methods of air compressor

air compressor generally have several kinds of classification?

Can be simple in the following ways:

1. According to the gas transmission volume, the so-called gas transmission volume refers to the volume of the gas discharged per minute when the air compressor is working, which is converted into the inhalation state. The small exhaust volume is less than 10 cubic meters/minute, the medium volume is 10~100 cubic meters/minute, and the large volume is more than 100 cubic meters/minute. Domestic models have 0.3, 0.6, 0.9, 1.6, 3, 6, 9, 10, 12, 20, 40, 60, 100 per minute of displacement. Among them, minicomputers and micro-minicomputers account for a large proportion. Super-large ones above 100 are rare, and limited to size and weight, piston air compressors with displacement above 100 are unreasonable.

2. According to the structure type, there are rotary type, piston type and membrane type. Among them, the piston type and rotary type in the screw type, slide type three forms are more common. Domestic piston type accounts for 95% of the output, while foreign screw type accounts for more than 90%. These three air compressors have their own advantages and disadvantages. Screw air compressor due to the complex rotor profile, high manufacturing cost, but small size, light weight, small parts are its advantages. In the case of the same displacement, the screw type air compressor is much more expensive than the piston type, and its maintenance must have special knowledge and experience.

3. According to the center line and relative position of the cylinder, it is divided into vertical, horizontal and angle type, and the angle type is divided into V type, W type, L type, etc.

Why does the compressor have to be shut down in an emergency? The compressor will inevitably have problems of one kind or another during use. Although they are all minor problems, they cannot make the compressor run normally. This makes people very * * *. We often ignore this minor problem. When the exhaust temperature exceeds 100 degrees Celsius or the load of the motor, the motor will start the protection device, the overcurrent protection device will automatically cut off the power supply, and the control board will display overload alarm, at this time, we need to deal with it immediately.

If it is not handled properly, the motor of the compressor will burn out, so the motor will stop immediately while the discharge valve is opened and the intake valve is closed to prevent the coolant from continuing to spray out of the compressor. Only when the unit is in abnormal condition during operation can emergency stop be carried out. If this situation does not occur, emergency stop is not allowed, otherwise it may cause system failure or liquid to be sprayed out from the air inlet. If you don't know the authenticity of oil, you can find our granklin air compressor to solve it. A good plan is the premise to ensure the normal operation of the unit.

Air compressor oil problems often occur in the process of using air compressor, its oil is also a problem, so in order to do preventive work in advance, granklin air compressor summarizes the following points for you to pay special attention:

1. Oil foam: usually the proportion of oil defoamer added is not appropriate, which sometimes leads to insufficient oil return and affects the service life of machine bearings;

2, the air outlet oil content is higher: the oil and gas separation of the oil is poor, the base oil in the hydride is more, making it difficult to separate from the compressed air;

3. Gluing: The base oil of air compressor oil is not good, and there are many ash impurities in it. Such substances are easy to oxidize. Through the oxidation reaction of high temperature and air, they form sludge like asphalt, causing the head of the air compressor to lock in serious cases. The general precursor of gluing is that the compressed air becomes smelly and the operating current of the air compressor is high;

4. The color of the old oil is abnormal: under normal circumstances, the color of the oil will turn dark red or black, but if the color such as purple indicates improper use of oil additives, it is recommended to replace the oil in time;

screw air compressors are divided into single screw and twin screw according to the number. According to whether lubricating oil is involved in the compression process, it is divided into oil injection and oil-free screw air compressors. Oil-free compressors are divided into dry type and water injection. Generally speaking, screw air compressors have simple structure, few wearing parts, low exhaust temperature, and large pressure ratio. They are especially not afraid of liquid and dust compression in the gas. The emergence of oil-injected screw compressors makes power technology and refrigeration Screw compressors (including screw air compressors, screw refrigerators, etc.) have developed rapidly at home and abroad.

The air compressor is equipped with oil temperature protection setting, and it will be shut down when the oil temperature exceeds 70 ℃. The reason for the high oil temperature is the failure of the oil cooler, but the cost of replacing the cooler is high. You can use the method of soaking in the detergent and then repeatedly flushing with pressurized water to clean the cooler to remove the cooler. Dirt.

This will extend the service life of the air compressor!

1. regular maintenance of air compressor maintenance, regular maintenance is essential. One is to plan ahead and kill the failure before it happens, and the other is to maintain the stable operation of the air compressor. There are some vulnerable parts in the air compressor, which should be replaced regularly within the specified period of use to avoid parts failure and cause problems with the air compressor. General operation after 300 hours to do a check, according to the use of their own decision to check the frequency. Regularly check the accessories and cables, and replace them immediately if they are damaged. In addition, keeping the filter clean can avoid many equipment failures. Unclean filters will reduce the performance of the compressor and the service life of the compressor. Clean the filter in time to keep the machine clean and dry, so as to give full play to its performance.

2. Select high-quality lubricating oil to strictly control the oil quality and oil quantity of the lubricating oil. If the quality is not good or the amount used is large, the lubricating oil will mix with dust and become hardened. Under a certain temperature and pressure, the lubricating oil will mix with organic matters in the lubricating oil and become black oil residue, forming carbon deposits, which will not only affect the normal operation of the air valve, valve plate, spring and piston ring, but also cause the air compressor to overheat to run.

Daily maintenance to ensure the long-term use of the air compressor, daily maintenance is the key. As a large-scale general-purpose mechanical equipment, the air compressor has a complex structure and powerful functions. To maintain this powerful function, it is necessary to check its working status from time to time. Daily work usually includes: draining the oil and gas barrel, checking the oil level, preparing peripheral equipment, such as sending water and electricity, opening the outlet valve of the compressor, etc.
