Printing cylinder common cause of the problem: 1. During installation or maintenance, and because of the maintenance process and maintenance technology, the expansion gap within the cylinder, cylinder partitions, partition and cylinder sleeve jacket inappropriate or lugs expansion gap plate inappropriate, an enormous expansion force after running the cylinder deformation. 2. Use of sealants cylinder poor quality, excessive or wrong type impurity; impurity particles inside the cylinder will be hard if the sealant sealing surface is difficult to closer integration. When the cylinder www.bykaiyuan.com insufficient tightening force 3. cylinder bolt or bolts of material failure, combined with the rigor of the press cylinder surface mainly by tightening the bolt force to achieve, the unit starts and stops, or changes in the load thermal stress and high temperatures generated by the bolt can cause stress relaxation, if stress is insufficient bolt preload will be gradually reduced. If the material is not good press cylinder bolt, the bolt in the long run which, under the action of thermal stress and expansion force of the cylinder is elongated plastic deformation or breakage, may be deficient in tightening force, the cylinder leak phenomenon . 4. cylinder bolt tightening sequence is incorrect, the general press cylinder fastening bolts fastening the same time from the middle, which is the vertical arc from side to side at maximum force or deformation of the largest local tightening, so will deform the biggest gap at the free end of the cylinder before and after the transfer, and finally disappearing gap. If it is from both sides to form a bow toward the middle tight gap, the gap will be concentrated in the middle of the joint surface of the cylinder, causing steam leaks.
