Safety operation regulations for air compressor

(1) the use of internal combustion engine and motor of air compressor shall comply with relevant provisions of internal combustion engine and motor

(2) the air compressor operation area shall be kept clean and dry. The air storage tank shall be placed in a well ventilated place, and welding or thermal processing shall not be carried out within 15m from the air storage tank

wear resistant welding rod

(3) when the air compressor inlet and exhaust pipe is long, it should be fixed, and the pipe should not have sharp bends; Long pipelines shall be provided with expansion deformation devices

(4) the air storage tank and gas transmission pipeline shall be subject to hydrostatic test every three years, and the test pressure shall be 150% of the rated pressure. The pressure gauge and safety valve shall be calibrated at least once a year

(5) the key inspection before operation shall meet the following requirements:

a. sufficient fuel and lubricating oil shall be added

b. all connecting parts are fastened, and all moving mechanisms and valves at all parts can be opened and closed flexibly

c. all protective devices are complete and in good condition, and there is no water in the air storage tank

d. the motor and starter shell of the electric air compressor shall be well grounded, and the grounding resistance shall not be greater than 4

(6) the air compressor shall be started under no-load state. After starting, it shall be idled at low speed. Check that the indicated values of all instruments meet the requirements. After the operation is normal, it shall gradually enter the load operation

(7 at the China International Rubber and plastics exhibition last month) the gas transmission hose should be kept unblocked without distortion. Before opening the gas supply valve, the gas transmission pipeline should be connected in 2012 and the relevant personnel on site should be notified before gas supply. No one is allowed to work or stand in front of the air outlet

(8) during operation, the pressure in the air storage tank shall not exceed the rated pressure on the nameplate, and the safety valve shall be sensitive and effective. Inlet and exhaust valves, bearings and components shall be free from abnormal noise or overheating

(9) the oil and water in the liquid gas separator, intercooler and aftercooler shall be drained once every 2 hours of operation. The oil and water in the air storage tank shall be discharged 1 ~ 2 times per shift

(10) in case of any of the following conditions, stop the machine immediately for inspection, find out the cause and eliminate the fault before continuing the operation:

a. water leakage, air leakage, electric leakage or sudden interruption of cooling water

b. the indicated values of pressure gauge, thermometer and ammeter exceed the regulations

c. the exhaust pressure rises suddenly, and the exhaust valve and safety valve fail

d. abnormal mechanical noise or strong spark of motor brush

(11) during operation, when the cylinder is overheated and shut down due to lack of water, water can be added only when the cylinder naturally cools down to below 60 ℃

(12) in case of sudden power failure during the operation of the electric air compressor, the power supply shall be cut off immediately, and the compressor shall be restarted under no-load state after the power is on

(13) during shutdown, the load shall be removed first, then the main clutch shall be disengaged, and then the internal combustion engine or motor shall be stopped

(14) after shutdown, close the cooling water valve, open the vent valve, drain the oil and gas in the coolers and air storage tanks at all levels, and then leave the post

(15) during construction in humid areas and tunnels, the exposed friction surface of the air compressor shall be regularly filled with lubricating oil, and the motor and electrical equipment shall be well protected against moisture
