Analysis of the causes of piston vacuum pump connecting rod fracture!
Thread Content
Two years ago, I had a piston vacuum pump. After replacing the new bearing bush, the connecting rod broke and the body was damaged after running for four hours. Please analyze it for me.
Where did the piston rod break? Where was the piston rod made? The main reason is the material problem!
The shape of the broken section of the connecting rod is very critical. From the broken section, it can be analyzed whether it is subjected to extrusion force or tensile force. Then consider the quality of the connecting rod, followed by the installation problem (including whether there is a problem with the positioning bearing). If the positioning is not good, the piston will get stuck, the connecting rod will continue to move, causing breakage, or the worm and worm gear will not be positioned well, and the transmission parts will become loose and seize, etc... Looking forward to the analysis results!
