If you have any questions regarding the repair of screw air compressors, I’ll @you!
What causes high vibration in screw air compressors, other than bearing issues?
If I have problems with the people around me, I hope you can answer
Most screw compressors use Ingersoll Rand; I would like to know how to adjust the screw meshing clearance. Thank you for your guidance
Host gap issue. Check the belt connection to ensure that the pulleys of the main motor are on the same plane, and that the belt is neither too loose nor too tight. For directly connected machines, check whether the couplings of the main motor are concentric and whether there are any issues with the elastomers. There’s nothing else; generally, that’s it. Please forgive any omissions.
When making adjustments, it generally involves adjusting the end face clearance. Since the tooth shapes of screw air compressors are fixed, if you adjust the end-face clearance properly, there will be no issue with the axial clearance.
Hello, our company happens to have a screw ethylene glycol compressor. I’m not very familiar with it; could you please provide information on the working principles of the compressor, oil separator, oil cooler, and dry evaporator in this unit, as well as common faults and their solutions?
What is the difference between screw compressors and rotary vane compressors? I have both types in my workshop, and I don’t understand why there are two options to choose from. I think their operating conditions are similar – they are both used to pressurize nitrogen or air in order to transport powder and granular materials through pipelines, and the pressure required for transportation is roughly the same.
Displacement, pressure, oil content – the gas discharged by a Roots compressor is oil-free. In the case of screw compressors, oil-injected types contain trace amounts of oil, while oil-free screw compressors contain no oil at all. What is the typical pressure range used for your Roots and screw compressors?
May I ask if your screw compressor is oil-lubricated or air-lubricated, and does it have synchronous gears?
