Causes and solutions for the screw head of screw air compressor
First, the first is insufficient lubricant
1 Long-term decommissioning (including transportation), Ingersoll Rand air compressor maintenance machine head internal fuel shortage, resulting in an instant lack of oil, resulting in stuck, so long-term equipment should first add enough oil to the machine head, Re-start
2 The running machine is insufficiently supplied with oil, including the replacement or addition of the lubricating oil. When the air compressor is maintained, the oil circuit is blocked and leaked, resulting in the oil shortage of the machine head;
3 If the oil level is too low, the bearing at the 2nd end of the screw rotor loses lubrication during operation, causing serious wear of the bearing and causing friction between the yin and yang screws.
Second, air compressor bearing aging
Serious wear and tear, the specific detection of bearing wear can be used when the bearing is not removed, the lower needle roller or ball inside the bearing, if you can easily dial the instructions need to be replaced; with the air compressor running time, the bearing will inevitably Wear occurs, resulting in an axial turbulence value and an increase in the radial turbulence value of the screw, which changes the gap between the screw and the screw, between the screw and the main body casing and the front and rear end faces
