Port Machinery Parts: How should machinery and equipment be repaired? Mechanical wear is a natural phenomenon with certain development laws that can be mastered. In order to maintain the normal operating status of mechanical equipment, prevent accidents, and maintain control over production, it is necessary to conduct regular inspections and maintenance of mechanical equipment according to the wear laws.
In factories, many worn and damaged parts are replaced from machinery every year. If these parts are repaired and reused, it can save a lot of materials and money. Therefore, the maintenance of mechanical parts is very important. As a mechanical worker, you must master the common repair methods of various main mechanical parts. So, port machinery parts: How should mechanical equipment be repaired?
Port Machinery Parts: How should mechanical equipment be repaired?
Mechanical wear is a natural phenomenon with certain development laws that can be mastered. In order to keep mechanical equipment in normal working condition, prevent accidents, and maintain control over production, it is necessary to regularly inspect and maintain mechanical equipment according to the wear laws, and eliminate potential faults in their infancy. Factories should establish a planned preventive maintenance system. The planned preventive repair system is to formulate an annual plan for the repair cycle and workload of various repair levels (repair work is divided into four levels: inspection, minor repair, medium repair, and overhaul) in advance, and carry out inspections and repairs according to the plan.
Port Machinery Parts: What is the content of each maintenance level?
1. Inspection work is generally carried out by operating personnel and on-duty maintenance personnel while the equipment is running. The main work is to check noise, vibration, leakage, and lubrication, and perform regular lubrication, etc.
2. Minor repairs should be carried out by workshop maintenance personnel. Minor repairs include tightening parts, wiping friction surfaces, grinding valve plates, installing packing, adjusting parts (such as adjusting bearings), checking oil rings, oil grooves, starting equipment, drive shafts, drive belts and chains, friction wheels, packing glands, various seals and pipes, etc.
3. In addition to all the work done in minor repairs, medium repairs also include repairing and replacing individual parts, such as re-casting and grinding bearing bushings, rotating journals, replacing brake pads, chains, gaskets and seals, repairing liners, etc.
4. Overhaul and overhaul work includes cleaning and reassembling mechanical equipment, replacing or repairing all worn parts, adjusting mating tolerances to meet technical requirements, repairing foundations, etc. During overhaul, mechanical equipment can also be modified.
5. For damaged parts found during inspection, the correct repair method should be selected for repair according to their structural characteristics and technical requirements. In order to shorten the downtime of mechanical equipment, spare parts can be used to replace the damaged parts first, and the damaged parts can be repaired after the equipment resumes operation.
Port Machinery Parts: What are the common repair methods for mechanical part wear?
The natural wear of mechanical components is the main form of wear, manifested in: destroying the initial matching of components, changing the geometric dimensions and shape of parts. In order to restore the working capacity of these components, it is necessary to restore their original matching characteristics, as well as the geometric dimensions and shape of the components.
There are two repair methods to restore the working capacity of components: one is to only restore the component performance, and the other is a repair method that restores both the fit and the geometric dimensions and shape of the parts.
