What should compressor users do when they want to adjust the pressure of the compressor? The pressure of a screw compressor is usually adjusted on the control panel. The specific steps for adjustment are as follows:
Key Takeaways
- Follow the documented startup and power-down sequence every time; shortcuts cause pressure shocks and wear.
- Keep the compressor room ventilated, clean, and free of combustible material.
- Train operators to recognize abnormal noise, vibration, and warning indicators before they escalate.
First press the shift key to enter the menu options and find the user parameters, then move the right key to enter, scroll down to find the loading force and unloading pressure. The loading pressure is when the compressed air pressure is lower than this value, the compressor will load and produce gas, and unload The pressure is the value at which the compressed air pressure will stop producing gas.
Then find the pressure option that needs to be adjusted. Press the right button to enter and you will be prompted to enter the user password. At this time, press up or down to enter the correct user password. After the input is completed, press the S key to enter, and then adjust the pressure according to your own pressure needs. , and then press the S key to save.
Then adjust the pressure according to your actual air pressure requirements. For example, if your minimum pressure requirement is 5bar, then the loading pressure can be set to 5bar. The maximum pressure, which is the unloading pressure, generally needs to be increased by about 2bar on the basis of the loading pressure. It should be noted that the maximum unloading pressure cannot be higher than the rated pressure of the compressor. Simultaneously, it is not recommended to operate the compressor at low pressure for a long time.
It should be noted that different panel types have different pressure adjustment methods. The above is for the method of adjusting the pressure of the button controller. If your compressor has a touch screen control panel, click the menu button to enter user parameter adjustment. Similarly, it is necessary to enter the correct user parameter password to enter user parameters. And adjust the load/unload cycling pressure according to your actual needs.

Selection and Sizing Considerations
Follow the documented startup and power-down sequence every time; shortcuts cause pressure shocks and wear. Keep the compressor room ventilated, clean, and free of combustible material. Train operators to recognize abnormal noise, vibration, and warning indicators before they escalate.
Frequently Asked Questions
What should I check before starting a compressor?
Check oil level, condensate drains, inlet filters, belt tension, and that all safety guards are in place.
Why does the machine need to warm up or cool down?
Proper warm-up distributes lubricant, and a controlled shutdown lets the unit depressurize and cool evenly.
How much clearance does a compressor need around it?
Follow the manufacturer clearance for intake, exhaust, and service access, typically at least one meter around the unit.
