Reasons for mirror-like wear on the cylinders of piston compressors, seeking help
Thread Content
For the 4M model, after on-site installation and a no-load test, the cylinder overheated in less than 2 minutes; upon disassembly, it was found that the cylinder bore at all levels had been burned and turned blue in the horizontal direction. On-site inspection revealed that the installation accuracy of the unit was poor, with serious deviations in the lateral and longitudinal levels of the fuselage. The levelness is off by several tens of microns. Could an expert please analyze why it’s a strain in the horizontal direction? Thank you! !
The deviation caused excessive radial force on the piston, resulting in wear of the cylinder.
During dry testing, there is no heat conduction through a medium; the cylinder expands slightly while the spark plug expands significantly, resulting in damage to the cylinder!
The horizontal pulling of the cylinder is also normal; ultimately, it’s due to improper alignment during installation. Fix it and try again.
