How to avoid the cracking phenomenon of rubber soft joints

How to avoid the cracking phenomenon of rubber soft joints
After using rubber joints for a period of time, some customers will suddenly react that small cracks will appear in the ball flange joints. What is the situation?
 
First of all, the strength of the connecting part of the rubber joint is relatively low, so if the connection length is not accurate, the strength of the joint will become lower and lower and cracks will appear. In the process of using rubber joints, inappropriate connection length, forcing beyond the connection length and arbitrary expansion and contraction may lead to cracking of rubber joints. After installation, rubber joints may rupture if they exceed the elastic design of other parts of the pipeline. Under the influence of outdoor bad weather, rubber joints may also crack when the temperature is lower than the use temperature.
 
Poor performance of the rubber used in the vulcanization process or failure of vulcanization of rubber joints. Excessive polishing. Rusty steel wire rope, etc. The strength of the joint part will be greatly reduced, and the joint part may be temporarily disconnected during use. In order to avoid cracking of rubber joints, attention should be paid to maintenance in normal use. Rubber joints are not only very important in the production process, but also frequently maintained in the use process. Improper use can greatly reduce the service life of rubber joints. When we use mechanical connection, the strength of the joint can only reach 40% to 40% of the strength of the band. 50, cold rubber method of good quality, the strength of the joint can reach sixty to seventy percent, the strength of the hot rubber joint can reach eighty to ninety percent, to ensure that the joint method is accurate without quality defects.
 
Rubber joint products are best-selling products, exported at home and abroad, rubber joints are easy to fatigue, rubber joints used for a long time, for some reasons, the cracked state will have an impact on the pipeline, so when using must pay attention to the method of use, let us understand how to avoid cracking. Rubber flexible joint installation cracking situation:
1 . The strength of the rubber flexible connection is relatively low. If the bonding method is not accurate, the strength of the joint will be reduced and may crack.
2 . Rubber soft connection in the process of use, the link length is not enough, forcibly exceed the link length, arbitrarily expand the shrinkage range, may also appear cracks.
3 . After the installation of rubber flexible joint, if the belt is pulled in other parts of the pipeline at will beyond the expansion range, cracks may also appear.
4 . Under the influence of outdoor bad weather and sunshine, the rubber flexible joint may crack when it is lower than the use temperature.
5 . The rubber used in the vulcanization process of the rubber flexible connection has poor performance or self vulcanization failure. Excessive polishing. Rusty wire rope, etc. The strength of the joint part will be greatly reduced, and it is easy to break the joint part in the process of use.
