First, before the operation of the air compressor, we should pay attention to the following problems:

　　1. keep the oil in the oil tank within the scale, and before the operation of the air compressor, the oil in the injector should not be checked below the scale of the scale.

　　2. check whether the parts of the movement are flexible, whether the joint parts are fastened, the lubrication system is normal, and whether the motor and electrical equipment are safe and reliable.

　　Before operation of 3. air compressor, it should be checked whether the protective device and safety accessories are complete.

　　4. check whether the exhaust pipe is unblocked.

　　5. connect the water source and open the inlet valves to make the cooling water smooth.

　　Two, air compressor operation should pay attention to long-term disabled after the first before starting to turn the engine and check, noted that there is no impact, stuck or abnormal noise.

　　Three, the machinery must start in the state of no load, and then gradually make the air compressor enter the load operation after the empty operation is normal.

　　Four, air compressor operation, normal operation, should often pay attention to various instrument readings, and at any time to be adjusted.

　　Five. In the operation of air compressor, the following conditions should be checked:

　　1. whether the temperature of the motor is normal and whether the readings of each meter are within the specified range.

　　2. the sound of the parts of each machine is normal.

　　3. air suction valve cover is hot, the sound of the valve is normal.

　　4. the safety protection equipment of the air compressor is reliable.

　　Six, when the air compressor operates for 2 hours, it needs to discharge oil and water in the oil-water separator, the intercooler and the rear cooler once, and the oil and water in the storage bucket will be discharged once a time.

　　Seven. When the following conditions are found in the operation of an air compressor, the machine should be stopped immediately to find out the reasons and to be excluded.

　　1. the end of the oil is broken or the cooling water is broken.

　　2. the temperature of the water suddenly rises or falls.

　　3. the exhaust pressure suddenly rises, and the safety valve is out of order.

　　The power part of the press shall be carried out in accordance with the relevant regulations of the internal combustion engine.

　　Installation site selection

　　When the 1. air compressor is installed, it is necessary to have a wide area of good lighting for operation and maintenance.

　　2., the relative humidity of the air should be low, the dust is less, the air is clean and well ventilated, away from flammable, explosive, corrosive chemicals and hazardous and unsafe articles, so as to avoid the places near the dusts.

　　3. air compressor installation, installation place of the ambient temperature in winter should be higher than 5 degrees, the summer should be less than 40 degrees, because the higher the temperature, the air compressor discharge temperature is high, it will affect the performance of the compressor, when necessary, the installation site should be set up ventilation or cooling device.

　　4. if the factory environment is poor and the dust is much more, the pre filter equipment must be added.

　　5. air compressor units in the installation site of air compressor should be arranged in a single row.

　　6. reserved access, the condition person can install the sky car, in order to maintain the air compressor equipment.

　　7. reserving maintenance space, the air compressor and the wall must have at least 70 centimeters distance between.

　　The comparison of the main air compressor:

　　The example of piston air compressor is that although for the production enterprises, the technical and financial threshold of twin screw compressor main engine and key control parts is very high, production is not easy. But for users, by the analysis on the table shows that in the scope of the twin-screw air compressor, compared with the corresponding piston type air compressor, the only drawback is the double screw purchase cost high, but this can be from the twin screw low use cost and long woking time get compensate, in fact, the purchase cost only a small proportion of total cost.
