Electric head of the electric head of common failures and maintenance

In the continuous production of modern industry, the electric head is affected by the working temperature, pressure, vibration and other factors, prone to leakage, leakage and other problems. The traditional repair method is to hit the fixture or welding and other processes, but has great limitations, and some leakage by the working environment safety requirements, can not be resolved on-site. Contemporary western countries for the above problems are mostly used in polymer composite materials
