Article 1 The air compressor must be taken care of and used by someone with a strong sense of responsibility. The user should master the knowledge of the structure, operation and maintenance of the machine, and operate and manage it according to the regulations. The use of the motor shall comply with the provisions of the motor chapter of this regulation.
Article 2. The air compressor should be parked indoors with air circulation and flat ground, or outdoors in a cool, clean and rain-proof place. The ambient temperature is 0~40C, and no welding or thermal processing is allowed within 15m from the air compressor. .
Article 3 Before starting the car, you must first check the oil level in the crankcase, and inject an appropriate amount of lubricating oil, especially when the new machine is used for the first time, be sure to inject oil. .
Article 4 Check whether the joints of the crankcase, cylinder, cylinder head, flywheel, balance iron and pipeline of the air compressor are tightly connected to eliminate looseness.
Article 5 Check the tightness of the transmission belt, the deflection of the transmission belt should be within the range of 10~15mm.
Article 6 Before running for the first time after long-term parking or maintenance, turn the fan flywheel by hand, the rotation should be flexible, without blocking phenomenon and abnormal noise, and observe whether the rotation direction of the crankshaft is the same as the calibration direction.
Article 7 Run with no load for 5~10min, and then run with load for 10~20min. and perform the following checks:
1. Whether the air pressure automatic switch, safety valve and pressure gauge work sensitively and reliably.
2. Whether there is air leakage or oil leakage at the relevant junctions.
3. Whether the breathing tube is breathing normally.
4. Is there any abnormal sound?
Article 8 When there is air pressure in the air storage tank, do not loosen any connecting parts.
Article 9 It is strictly forbidden to adjust the safety valve at will, so as to avoid serious consequences.
Article 10. Do not use the method of pulling out the power plug to stop the machine. Before restarting the air compressor after stopping, the compressed air in the air storage tank should be exhausted.
Article 11 A wire with a cross-section smaller than the specified and a length of more than 10m shall not be used as the power cord.
Article 12 If it is found that the relief valve cannot be vented during automatic shutdown in the state of electric control operation, the cause should be immediately identified to avoid damage to the motor. .
Article 13 When the compressor has severe vibration and abnormal noise, it should be stopped immediately for inspection, and the machine can be turned on after troubleshooting.
Article 14 Do not touch the cylinder head, exhaust pipe and one-way valve at will after starting the machine to avoid burns.
Article 15 The lubricating oil used in this machine must be special compressor oil, and other mechanical oil shall not be used instead. No. 13 and No. 19 compressor oils must be used in winter and summer respectively, and the lubricating oil must not contain impurities and dirt.
Article 16 The oil level of the lubricating oil must be controlled within the specified oil level line, otherwise the oil temperature will be too high, the oil consumption will be too large or the related parts will be damaged (the whole machine will be scrapped in serious cases).
Article 17 When a new machine runs for 10 hours, it should be replaced with new oil and the crankcase should be cleaned. After that, the new oil should be replaced with new oil and the crankcase should be cleaned every 500 hours of operation.
Article 18 When driving in winter, the lubricating oil must not freeze, otherwise it should be heated to ensure reliable lubrication.
Article 19 The maximum oil temperature of the lubricating oil in the crankcase shall not exceed 70°C.
Article 20 Always check whether the pressure gauge and automatic air pressure switch are sensitive; whether the oil level and oil temperature of the lubricating oil are within the specified range, and whether there is air leakage or oil leakage.
Article 21 The gas delivery hose shall be kept unobstructed, and shall not be twisted or bent sharply. Before opening the gas delivery valve, the gas delivery pipeline shall be connected well, and the relevant personnel on site shall be notified before delivery of gas. No one should work or stand in front of the air outlet. .
Article 22 The pressure in the gas storage tank shall not exceed the rated pressure of the nameplate during operation, and the safety valve shall be sensitive and effective. There should be no abnormal noise or overheating of the intake and exhaust valves, bearings and components.
Article 23 The oil and water in the liquid-gas separator, intercooler and aftercooler should be drained once every two hours of work. The oil and water in the gas storage tank should be discharged once per shift. The oil and water in the gas storage tank should be discharged 1~2 times per shift.
Article 24 When there is a sudden power failure during the operation of the electric air compressor, the power supply should be cut off immediately, and restarted under no-load state after the power is turned on.
Article 25 When stopping, the load should be removed first, then the main clutch should be disengaged, and then stop
The operation of an internal combustion engine or electric motor.
Article 26 After shutdown, the cooling water valve should be closed, the air release valve should be opened, and the oil, water and stored air in the coolers and air storage tanks at all levels should be released before leaving the post.
Article 27 The gas storage tank and the gas transmission pipeline shall be subjected to a hydraulic test every three years, and the test pressure shall be 150% of the rated pressure. Pressure gauges and safety valves should be calibrated at least once a year.
