Switching sequence
1. Before starting the machine, check whether there is oil leakage in the air compressor pipeline, whether the screws are loose, and confirm the power supply voltage.
2. Before starting the machine, check whether the cooling oil level of the oil barrel is between the two scales. If the oil level is lower than the lower scale line, add lubricating oil to the oil barrel.
3. Before starting the machine, slightly open the drain ball valve under the oil and gas barrel to drain the condensed water in the oil and gas barrel. When you see oil flowing out, quickly close the ball valve.
4. Start up: Turn on the refrigerated dryer first, press the ON button to let the dew point temperature reach 5 degrees or below, and then turn on the air compressor (Note: For the water cooler, open the cooling water ball valve first).
5. Start the air compressor: press the start button or the ON button, if the air compressor sounds abnormal or other emergency situations, please press the emergency stop button.
6. Start up the adsorption dryer: Check whether the water in the air storage tank and the precision filter is drained cleanly. When the pressure reaches 8 KG, open the ball valve and start the adsorption dryer.
8. Shutdown: press the stop button or OFF, (shutdown sequence is to first turn off the adsorption dryer, then turn off the air compressor, then turn off the refrigerated dryer, then turn off the ball valve, and turn off the power supply). Do not pull directly if it is not an emergency. brake and use the emergency stop button to stop.
9. If the laser machine is turned on: Let the laser cutting head exhaust for 1 to 2 minutes, then take out the lens to see if it is contaminated, wipe it clean with alcohol, and then put it in and turn it on.
Precautions during operation
1. Observe the temperature displayed on the control panel, the normal value is between 80°C and 95°C.
2. For air storage tanks, precision filters, and cold dryers installed with drains, check whether the drainage and exhaust are normal every 4 hours. Drain once manually and drain the filter every 30 minutes.
3. Check whether the three-phase current is balanced and whether the voltage is normal.
4. Observe oil pipe joints and others for oil leakage.
5. It is recommended to wipe the lens of the laser machine with alcohol every 4 hours
Daily maintenance of air compressor
1. If there is a high temperature warning or other alarm displayed on the power-on panel, please check whether the oil level is normal (the power-on state should be between the two red lines, lower than the lower red line or no oil can be seen, you need to stop and fill from the fuel port) to dissipate heat Check whether the radiator is blocked (use a flashlight to see if the radiator is transparent or dusty).
2. It is forbidden to mix lubricating oils of different brands and manufacturers, and it is forbidden to use unqualified lubricating oils.
3. Keep the air circulation in the air compressor room, and keep the air compressor and the surrounding environment clean.
4. Every 2-4 days, stop the machine and take out the air filter element, blow out the dust inside the air filter element and the air filter cover from the inside to the outside, and then put it back. (Note: Replace the spare air filter directly without stopping the machine for 24 hours).
5. Every day/every shift, the air compressor radiator and all air inlets should be blown to prevent dust and the radiator of the cold dryer. Clean the dust thoroughly by purging, electrical appliances, motors and disassembling the radiator cleaning board every week, and clean the heat transfer tube of the water-cooled cooler for the water-cooled machine every six months. (Attention: shut down and power off for cleaning, use dry gas to blow the radiator from the outside to the inside and open the door of the air compressor completely, after the radiator blows through, install the radiator cleaning plate).
6. The first guarantee of the air compressor is to replace the lubricating oil, oil grid and air filter. The time is 500 hours or 3 months. The maximum guarantee is 1 year or 3000 hours or according to the viscosity of the lubricating oil. Replace the oil, engine oil, Oil grid, air filter. The activated alumina, molecular sieve and precision filter element of the adsorption dryer are recommended to be 1 year or 3000 hours, or if the moisture content of the lubricating oil is found to be high, please replace it immediately.
7. Drain the condensed water from the gas storage tank and precision filter regularly every day.
8. Regularly add motor-specific grease to the front and rear ends of the motor every half a year or 3000 hours (note: no filling is required for the one-piece shaft).
