When the knitting machine manufacturer manufactures, the equipment is in the running state for a long time, and the static data deformation and dynamic deformation of the equipment will change all the time, which will gradually increase the partial deviation and system deviation of the parts that have been tightened or connected. As a result, the spatial relative position of some parts is shifted, and the process interval changes, resulting in a change in the process state and a decrease in product quality. Whether the device is running or not, its static data shape always exists. After running, the dynamic deformation is improved. These two deformations deform the screw cap and the thread of the bolt, causing the joint to loosen gradually, the gasket becomes soft after being squeezed, and the elasticity of the self-locking nut decreases.
- Use safety inspection to check the key process components of each piece of equipment, and whether the tightened connection parts are loose, and tighten the loose parts in time.
- Knitting machine manufacturers purchase standard tightening joints from designated domestic factories, and build safety inspection systems with inspection as the core.
- Unify the tightening procedures of fasteners to minimize under-tightening or over-tightening, leading to potential failures or reducing the service life of tightened parts.
Establish an inspection-centered inspection system In order to better maintain the characteristics of the equipment, inspect the equipment in accordance with the specifications, so that the abnormal state of the equipment can be detected at an early stage, and the establishment of an inspection-centered inspection system is a good way to do maintenance work main way.
The so-called maintenance refers to the inspection tour of the key parts and new items of the equipment. Condition-based maintenance highlights the status from beginning to end. For the equipment in daily operation, every part of each unit is inspected every day. Consistent with the tightening operation method of fasteners, avoid excessive tightening or excessive tightening, which may cause potential problems or increase the service life of the overall tightening.
These two deformations deform the fingerprints of the anchor bolts and bolts, causing the joint to gradually loosen, the bottom pad becomes soft after being squeezed, and the spring seal ring elastically lands and the like.
