Description

Technical Field

[0001] This utility model relates to the field of piston compressor maintenance equipment, specifically to a piston compressor cylinder and cylinder liner end face leveling tool. Background Technology

[0002] Currently, piston compressors are machines used to compress gases, increase gas pressure, or transport gases. They are widely used in industries such as petrochemicals, metallurgy, machinery manufacturing, and refrigeration, and are often key equipment in these plants. Their stable operation is particularly important. In actual operation, some piston compressors often experience abnormal cylinder noise. Upon disassembly, it was found that some of these noises are mainly due to the misalignment between the cylinder liner and the cylinder end face. The cylinder end face is slightly higher than the cylinder liner end face, presenting a slight bulge. This prevents the cylinder head from properly pressing the cylinder liner. During operation, due to the action of piston force and gas force, the cylinder liner will inevitably move axially within the cylinder, causing impacts and abnormal noises. Prolonged operation poses a significant risk. Since there are no repair methods available on-site, the current repair method is to completely disassemble the cylinder and send it back to the factory for processing. This results in a large workload, long construction period, and high costs, affecting production operations. Utility Model Content
