Breakage of the reciprocator support ring

The possible reasons for fractures in this situation are as follows: 1. Material defects: The materials used for the support rings and piston rings may have defects or fail to meet the required standards, such as insufficient hardness or toughness. 2. Design issues: The design of the support rings and piston rings may not be optimal, such as with regard to dimensions, shape, or uneven load distribution. 3. Excessive working pressure: Operating conditions with an intake pressure of 5 Mpa and an exhaust pressure of 11 Mpa place significant stress on the mechanical components, potentially exceeding the bearing capacity of the support rings and piston rings. 4. Incorrect installation or wear: Imprecise alignment during installation, improper tightening, or wear resulting from long-term use can also be among the causes of fracture. 5. Poor lubrication: If the lubrication system does not function properly, it can result in insufficient lubrication of the support rings and piston rings, increasing friction and wear, which may lead to breakage. It is recommended to conduct a thorough inspection and analysis of the materials, design, and installation process, as well as to check whether the lubrication system is functioning properly. .

There are several possibilities: 1. Is there a problem with the quality of the spare parts? Currently, low-price bids are common in the domestic market; the quality of some products is concerning, and the dimensions also need to be confirmed ； 2. Is there a problem with the piston rod’s play? Does it need to be adjusted?

Okay, this is Holbig’s product, a first-class cylinder

Have you consulted the manufacturer? Using Holbig doesn’t necessarily mean it won’t fail; it’s recommended to conduct a thorough inspection of the compressor

Based on the description of the problem, it seems that a foreign object has entered the cylinder, causing damage to the guide ring (support ring), which in turn led to damage to the sealing ring. It is recommended to clean all the connecting pipes beyond level 1 to remove any foreign objects. It is also necessary to disassemble and inspect the compressor inlet filter, as well as to thoroughly examine the valve plates of the suction and exhaust valves at each stage. For reference.

If foreign objects get inside, the cylinder liner will wear out; check the degree of wear on the cylinder liner to identify the cause

Check the clearance between the support ring/piston ring and the ring groove to see if it is too large causing the issue
