Classification, tasks, and implementation steps of equipment inspection

Thread Content

1. Classification of equipment inspection: Equipment inspection is usually divided into three types: daily inspection, regular inspection, and detailed inspection. Routine inspection 01 relies primarily on operators who, during each shift on a daily basis, use their senses and simple testing instruments to check the technical condition of specified parts of the equipment before, during, and after operation, in order to detect signs of faults and potential hazards promptly. Regular inspection 02 refers to the checks carried out by specialized maintenance personnel at predetermined intervals (weekly, every two weeks, or monthly), without disassembling the equipment, using the senses as well as appropriate instruments and tools, in accordance with specified items, procedures, methods, and standards. Precision inspection 03 refers to the evaluation and inspection carried out regularly or irregularly by specialized technical departments using dedicated instruments and equipment, with some or all of the equipment disassembled. Precise inspections include random mandatory inspections, inspection for accident investigation, disassembly inspections for administrative supervision or operational condition testing, evaluation and acceptance tests for routine or major equipment repairs, as well as various bench tests conducted during maintenance. II. Contents of inspection tasks (1) Contents of routine inspections Routine inspections are aimed at detecting any abnormal conditions; they should be carried out during shift changes or breaks, so the inspection items are simple and easy to carry out, typically taking about “% minutes. (2) Contents of regular inspections: Regular inspections focus on detecting the degradation trends of equipment or components; therefore, the inspection items are more thorough than those in daily inspections. However, these are generally non-dismantling inspections, and they usually take about &% minutes. (3) Tasks of precision inspection Precision inspection focuses on accurately measuring the degree of degradation of equipment or components, with inspection items including the measurement of the technical parameters of all components of the equipment. However, the specific items to be inspected and the required time must be determined separately depending on the type of precision inspection. III. Steps for carrying out inspections – Steps for daily inspections: (1) Refer to the equipment operation manuals and maintenance guides, and take into account the company’s management experience as well as the technical skills of the operators, in order to determine the scope of inspection, the specific items to be inspected, and the methods to be used for these inspections. (2) Establish technical standards, work specifications, and procedures for routine inspections. Units with such requirements must also prepare a table comparing fault symptoms, causes, and corrective measures. (3) Design a daily inspection record form. (4) Establish a guidance and supervision system for routine inspections, with dedicated personnel conducting regular spot checks and providing guidance. (5) Conduct regular inspection training courses, implement technical assessments, and require certification to work. (6) Formulate and implement an economic assessment scheme for routine inspections. Steps for implementing regular inspections: (1) Based on the objectives of regular inspections, and taking into account the company’s management experience as well as the technical skills of the dedicated inspectors, determine the scope of inspection, the specific items to be inspected, and the methods to be used for these inspections. (2) Refine the inspection items, contents, frequency, and evaluation criteria, based on the wear patterns of the equipment as well as the requirements to ensure the overall functionality, precision, and safety of the device. To take into account the maintenance level, frequency, and current status of the inspection equipment for the same device, regular inspections can also be divided into several levels. (3) Refine the inspection methods and establish a checklist of inspection items, targets, matters, instruments, and diagnostic criteria. (4) Establish regular inspection stations (points) equipped with testing instruments. (5) Establish regular inspection work standards and procedures. (6) Establish a guidance and supervision system for regular inspections, with senior management conducting periodic spot checks and providing guidance. (7) Conduct regular inspection training courses, provide training on the operation of testing instruments and carry out technical assessments, issuing certificates for those who pass. (8) Formulate and implement a regular inspection and economic assessment plan.
