2. Air compressors work area shall be kept clean and dry. As pressure vessels, air tank should be placed on a well-ventilated place, to minimize the temperature, in order to improve the quality of stored compressed air, away from heat sources, shall not be less than 15m away from the air tank welding or hot work.
3. Air compressor into the exhaust pipe is longer, should be fixed, piping shall not have sharp bends, to reduce the gas resistance; To prevent deformation of the metal pipe due to thermal expansion and contraction of a long line stretching deformation device should be located .
4. Road, air tank and pipeline pressure test should be made once every three years, the test pressure shall be 150% of rated pressure. Pressure gauge and safety valve should check at least once a year.
5. In order to ensure the normal use of air compressor, air compressor operations in accordance with the following requirements before inspection:
(1) fuel, run plenty of oil are added;
(2) fastening the joints, sports organizations and ministries of the opening and closing valves and flexible;
(3) of the complete good guard, air tank is no water in;
(4) electric air compressor motor starter and a good ground cover, ground resistance of less than 4Ω.
6. Air compressor should start at no-load condition, after a slow start air running, view the value of each instrument instruction to meet the requirements, in normal operation, and gradually into the load operation.
7. If the pipeline transportation of compressed air blowing directly to the human body, can cause personal injury accidents, gas hose should be kept clear, not distorted, open delivery valve before the pipeline connection should be good, and notify the site personnel before aspirated. In front of the outlet may not work or was standing, to prevent air leakage wounding.
8. Air tank on the safety valve is to limit the pressure within the air tank does not exceed the specified value of the security devices, operating in the air tank pressure shall not exceed the nameplate rated pressure relief valve should be sensitive and effective. Jin, exhaust valve, bearings and the parts should be no abnormal noise or overheating.
9. Each work 2h, should be liquid-gas separator, intercooler, oil cooler after the discharge time. Air tank within the class should discharge water 1-2 times.
10. Found that the following conditions should immediately stop inspection, identify the causes and troubleshooting before you continue to work:
(1) leak, leak, leakage, or sudden interruption of cooling water;
(2) pressure gauges, thermometers, meter indication exceeds requirements;
(3) a sudden increase in exhaust pressure, exhaust valve, safety valve failure;
(4) there is abnormal sound or mechanical motor brushes a strong spark.
11. Operation, leaving the cylinder in the water thermal shutdown, if the immediately into cold water, high temperature of the cylinder block contraction due to sudden cold, prone to cracks and cause damage. Therefore, the natural cooling to the cylinder should be below 60 ℃ before adding water.
12. Electric air compressor operation when a sudden power outage, you should immediately cut off the power supply, such as call and re-start at no load condition.
13. Shutdown, the load should be shed, and then separating the main clutch, then stop the operation of the internal combustion engine or electric motor.
14. After the shutdown, the cooling water valve should be closed, playing open valve, release at all levels within the water cooler and the air tank and save gas, before undergo.
15. In wet areas and tunnel construction, the friction surface of the air compressor should be regularly exposed filling oil, the motor and electrical equipment should be ready moisture protection.
