Is the main focus of inspections \"patrolling\" or \"inspection\"?

I. What is the purpose of inspections? It enables the timely detection of abnormalities in the equipment and allows for simple troubleshooting, ensuring stable production operations. II. Inspection Methods: During equipment inspections, inspectors must strictly follow the established procedures, exercising a high level of responsibility and applying the inspection methods of ‘looking, listening, asking, and feeling’. When looking, one needs to be observant; when listening, one needs to use both ears and nose; when asking, one needs to be communicative; and when feeling, one needs to use hands. Use the eyes, ears, hands, and brain to detect potential accident hazards promptly and eliminate them right away. III. Inspection Contents Regarding the inspection contents, checks are carried out from three aspects: the functionality, safety, and cleanliness of the equipment, with methods such as visual inspection, listening, and tactile examination being commonly used. 1. Functionality: That is, whether the device or facility can fulfill its functional attributes. Things such as whether oil pumps, water pumps, and fans can achieve the specified oil pressure, water pressure, and air pressure; whether fire hydrants can be used at any time; whether water level gauges and pressure meters accurately display the water level and pressure; and whether the floor tiles ensure a smooth surface. 2. Safety: This includes checking whether electrical protection measures are in place, whether all safety measures have been restored after maintenance, whether the pressure, temperature, vibration, and oil level of the equipment are within normal ranges, whether pipeline insulation is proper, and whether anti-freezing and cooling measures are adequate. It also covers issues such as inadequate on-site lighting and missing markings, in order to prevent personal injuries and operational errors. 3. Neatness: This includes issues such as leaks, spills, and other defects; as well as accumulation of dust, oil, water, and debris. Wires should not be hung haphazardly, pipes should not be placed randomly, and trash should not be left around. IV. Key Inspections: Special inspections are carried out on critical equipment: equipment with defects, equipment that is operating despite having issues but has not been repaired, equipment that requires maintenance, equipment that cannot be put into use due to special reasons, equipment equipped with electrical protection, newly commissioned equipment, recently upgraded equipment, and equipment that has previously experienced problems. Special attention is given to equipment that is essential for the safe operation of the entire unit, such as air compressors, supply and exhaust fans, flame detection fans, oil supply pumps, feed water pumps, condensate water pumps, cooling water pumps, and diesel generators. At the same time, under special weather conditions, certain equipment that is exposed to rain, wind, snow, cold, or heat also requires regular inspection. V. Handling of Equipment Defects 1. When a defect occurs in the equipment, any issue that can be resolved by the operators and maintenance staff should be fixed immediately, with detailed records kept in the log. 2. Equipment defects that cannot be resolved by the operators on duty must be carefully documented and reported at each appropriate level. At the same time, operators should operate with care, pay close attention, and monitor the development of such defects. 3. Before proceeding to address each defect, appropriate measures must be put in place, with a designated person responsible, to prevent the defect from worsening. 4. Defects that affect the unit’s output must be reported to the duty officer immediately. VI. Misconceptions about inspections: Strengthening inspections to detect potential hazards in a timely manner and nip accidents in the bud is key to ensuring long-term stable operation, which requires us to maintain high standards of inspection quality. And during inspections, we often have many misconceptions. 1. Pay attention to moving equipment and the inspection of critical equipment, while neglecting the inspection of stationary equipment, as well as secondary and spare equipment. 2. It leads to complacency regarding existing flaws and risks that cannot be addressed online. 3. Emphasize the form of inspections while neglecting their quality. The roles of the personnel are different. 1. Equipment inspectors are full-time professionals who have received specialized training. 2. Equipment inspection mainly relies on the information provided by equipment patrol personnel. The job responsibilities vary. 1. Equipment inspectors use their senses or simple instruments to conduct regular inspections of equipment. During these inspections, they identify any abnormalities or potential problems by comparing the equipment’s condition with established standards. They gather initial information about equipment failures, providing inspectors with details on the specific areas, components, and aspects that need to be checked, thereby enabling them to carry out their inspections in a targeted and efficient manner. 2. Equipment inspection primarily refers to the equipment maintenance staff, who are responsible for fixing equipment failures and ensuring the proper operation of production equipment; they conduct thorough inspections and repairs on faulty equipment. 3. In some organizations, equipment inspection is also referred to as maintenance work. Regarding daily equipment inspections and routine equipment checks: (1) Equipment inspectors are dedicated staff who are primarily responsible for inspecting the equipment in a specific production process stage. He is different from maintenance staff and repair personnel, as well as from maintenance technicians; he is a specialized individual who has received special training. Equipment inspectors use their senses or simple instruments to conduct regular inspections of equipment. During these inspections, they identify any abnormalities or potential problems by comparing the equipment with established standards, thereby obtaining early information about equipment failures. This information helps the inspectors determine the specific areas, components, and aspects of the equipment that need to be checked, allowing them to carry out their inspections in a targeted and efficient manner. (2) Regular equipment inspections refer mainly to the equipment maintenance staff, who are responsible for fixing equipment failures and ensuring the proper operation of production equipment. Based on the information provided by the equipment inspection staff, they conduct detailed checks and repairs on the faulty equipment. The intelligent equipment inspection management system can intelligently diagnose equipment failures, enable predictive maintenance, reduce downtime caused by equipment failures, and improve production efficiency. (3) Daily equipment inspections and routine equipment checks are essentially part of the same role; it involves monitoring whether the equipment is operating properly, checking for any abnormalities, providing a better basis for repairs, reducing the time required for repairs, and restoring normal operation of the equipment as soon as possible.
