Workflow of single screw air compressor startup and commissioning

Workflow of single screw air compressor startup and commissioning Workflow of single screw air compressor startup and commissioning 1. Detect and record the operation of the air compressor within 2 hours. 2. Turn off the air compressor and check the connecting pipes for oil leakage, water leakage, and air leakage. 3. Adjust the loading / unloading pressure of the air compressor according to user requirements. 4. Check whether the dimensions of the inlet pipe and outlet pipe of the cooling water pipe meet the standard, and whether the filter, pressure gauge and stop valve (water cooler) are installed on the inlet pipe. 5. Check whether the square number of the main cable connected to the air compressor meets the standard, and whether the direction and length of the cable meet the standard. 6. Remove the anti-vibration fixing block during transportation, open the electric control box and repeatedly tighten all circuit connections, open the intake valve, add about 1 liter of lubricant and manually crank. 7. Close the external power supply, measure whether the input voltage is within the standard range of plus or minus 5%, and measure whether the input and output voltage of the transformer in the electric control box reaches the standard. 8. Adjust the parameters of the control panel. 9. Open the air supply valve on the air compressor. 10. Jog the start / emergency stop button to check whether the main motor and the fan area motor are running in the correct direction. 11. After all are correct, press the run key to start the air compressor and enter the trial operation state. 12. Check whether the startup time of the air compressor from star to triangle meets the standard. 13. Check and record whether the current value of the air compressor is within the standard rated range when it runs to the highest pressure. 14. Detect and record whether the three-phase current of the main drive motor of the air compressor is balanced in the loading / unloading state, and whether the current value of the fan motor and the balance of the three-phase current are within the standard range. 15. Check and record whether the exhaust temperature value of the air compressor is within the standard range when it reaches the highest pressure and runs stably for 30 minutes during loading operation. 16. Detect and record whether the noise value and vibration value of the air compressor are within the standard range during operation, and whether there is any other abnormal noise in the main head during operation. 17. Train users on-site operators. 18. Check whether the outlet pipeline system of the air compressor is connected according to the standard, including whether the size of the air pipe is matched, whether the connection of the rear filter is correct, whether the connection of the cold dryer is correct, and whether the selection of the air tank Reasonable, and whether all kinds of bypass pipeline valves are reasonably and reliably connected. 19. Check whether the ground where the air compressor is placed is smooth and whether it meets the requirements of the air compressor placement standard 20. Check whether the exhaust pipe connected to the air compressor is installed with an exhaust pipe according to the standard, and whether the cross-sectional area of the exhaust pipe meets the design standard (air-cooled machine).
