There are many things that need to be paid attention to when purchasing chains. Many very professional people do not know very much about the method of purchasing chains. There are many functions of chains, so what should we pay attention to when purchasing chains? Let's take a look at some of the introductions given by experts.

The appearance inspection of the chain is whether the inner/outer chain pieces are deformed, cracked, embroidered; whether the pins are deformed or rotated, embroidered; whether the rollers are cracked, damaged. Excessive wear; whether the joints are loose and deformed; whether there is abnormal noise during operation Or abnormal vibration, whether the chain lubrication condition is good.

The detection method of the chain is that the chain is cleaned before measurement; the chain under test is surrounded by two sprockets, and the upper and lower sides of the chain under test should be supported; the chain before measurement should stay under the state of applying one-third of the ultimate tensile load 1min; during measurement, apply the specified measurement load on the chain to tension the upper and lower chains. The chain and the sprocket should ensure normal meshing; measure the center distance of the two sprockets.
