Introduction: In order to prevent the rubber joint from cracking, we should pay attention to the protection of the rubber joint in the normal use. According to the following operation steps, people will reduce the occurrence of fracture. First, the strength of the link part is relatively low, then if the hot connection method is not accurate, connect

To prevent Rubber joint We should pay attention to protect it in normal use. According to the following operation steps, people will reduce the occurrence of fracture.
First, the strength of the link is relatively low, so if the hot joint method is not accurate, the strength of the joint will be lower, and there may be cracking
Second, the length of the link in the process of use is not enough, forced beyond the length of the link, random expansion and contraction range is also likely to crack
Third, after installation, pull the belt at other places of the pipeline, which is beyond the scope of expansion and contraction
Fourth, under the influence of outdoor bad weather, it is possible to crack when the temperature is less than the service temperature.
5. In the process of vulcanization, the commonly used rubber has poor function or has long been ineffective in self sulfurization, excessive grinding, steel wire rope corrosion, etc., the strength of the joint may be greatly affected, and the joint may be broken when used. When we use the method of 60% to 40% of the joint strength, we can achieve the joint strength of only 80% to 70% of the joint strength with the method of hot glue.
The installation team from the on-the-spot use shows that the rubber joint produced by Luo Ying has considered the requirements of chemical plant production in terms of corrosion resistance, vibration reduction, vibration isolation and compression resistance, and has solved the problem of damage to adjacent equipment or pipelines caused by vibration of some rotating equipment from the source, and has a long service life. For some equipment and connecting pipes that need to be installed on site, due to the limitation of on-site standards, the installation of pump and pipeline is not aligned (often encountered in maintenance) or the corresponding surfaces of two connecting parts are not parallel. The rubber joint can be used as a compensation for axial and radial offset; It can reduce the distortion and deformation of pipes and equipment caused by external forces, so that the equipment installation can meet the requirements of design and installation and ensure normal operation. Our factory uses it in many places Flexible rubber joint According to different media environment, the average service life is 1-5 years, which is much better than expected.
