Maintenance issues of large-scale equipment, turning operations for spare oil pumps

For the turning operation maintenance of the standby oil pump, the following measures should be taken: 1. Before carrying out the turning operation maintenance, the function of the low oil pressure interlock should be disabled first to prevent accidents caused by accidental operations. 2. A manual switch can be installed to disconnect the interlock function of the backup oil pump from the system; this way, no complicated interlock procedures are required during maintenance tasks, simplifying the process and saving time and effort. 3. The outlet valve of the standby pump for the make-up pump should be set to the open position at all times. Additionally, a pressure reducing valve or throttle valve should be installed at the oil pump outlet. This ensures that the oil pressure remains stable during the operation of the make-up pump, thereby preventing any equipment malfunctions caused by fluctuations in oil pressure. In general, the maintenance of standby oil pumps should balance both safety and efficiency. Taking appropriate measures can ensure the smooth operation of the equipment and reduce the occurrence of accidents. .

(1) Regular turning 1. Each operating area is responsible for the daily management of turning operations for the rotating equipment under its jurisdiction. 2. The equipment must be turned over before starting up. 3. For equipment that cannot be cranked, such as canned pumps and metering pumps, in accordance with the operating procedures for pumps and machinery, the jog function can be used to check whether the equipment is in good condition. It is required that the equipment be ready for immediate operation at any time. 4. If any abnormalities are detected during the equipment rotation (such as leaks, jamming, friction, noises, etc.), it should be reported immediately to the person in charge of the equipment in the workshop or to the workshop supervisor. 5. After each rotation of the equipment, the “Equipment Rotation Record” must be filled out, with details including the name of the equipment, rotation markings, rotation time, and the person who performed the rotation. 6. For certain large or special equipment, if the operating procedures specify additional requirements regarding gear turning, those specifications shall be followed. 7. Each branch factory shall strictly comply with these regulations, and the company will include regular equipment rotation checks as part of the assessment criteria for on-site equipment management. 8. Method of turning the equipment: First method: (1) All operating equipment must be turned regularly, once a day. (2) The shift team working during the day shift shall turn the stalled equipment once a day, completing this task before 9:00 in the morning, and keep records of it, including the name of the equipment, the starting and ending points, as well as any issues encountered. (3) Mark obvious turning marks on the exposed parts of the rotating equipment (such as shaft ends, couplings, etc.). Divide the circumference of the coupling or shaft end into two equal parts, and mark A and B with red paint at the two points on the circumference. (4) Each time the shaft is turned, it starts from a certain turning mark; after turning it several times (not less than three times), if point A is at the top position before this turn, then point B is placed at the top position (i.e., the 12 o’clock position) to complete one cycle of shaft turning. Second type: (5) All operating equipment must be rotated regularly, once per shift. (6) The operating shift shall turn the shaft of the stopped equipment once per shift: before 9:00 during the day shift, before 21:00 during the middle shift, and before 1:00 during the night shift. Records must be kept, indicating the name of the equipment, the starting and ending points, as well as any issues encountered. (7) Mark obvious turning marks on the exposed parts of rotating equipment (such as shaft ends, couplings, etc.). Divide the circumference of the coupling or shaft end into four equal parts, and mark A, B, C, and D on these four points using red paint; these marks correspond to the four shift teams, namely point A → Shift 1, point B → Shift 2, point C → Shift 3, and point D → Shift 4. (8) Each time the shaft is turned, starting from a certain turning mark, after turning it several times (not less than three times), the mark corresponding to the team shall be placed in the top position (i.e., at the 12 o’clock position) to complete one cycle of shaft turning.

(II) Accident handling 1. Equipment accidents include equipment damage, personnel injuries, etc. In the event of a equipment accident, it is necessary to report it immediately to the person in charge of the equipment in the workshop or to the workshop supervisor, and the incident must be handled and reported in strict accordance with the relevant provisions of the company’s \"Rules for Handling Equipment Accidents\". 2. When dealing with equipment accidents, it is necessary to ensure safety at the scene and take effective measures to prevent the accident from spreading and to protect evidence at the scene. 3. For minor faults, they should be resolved promptly to ensure the proper operation of the equipment ； In the case of severe failures, the machine should be shut down for maintenance, the fault should be resolved and recorded, so that the causes can be analyzed and management can be improved in the future. 4. When dealing with equipment accidents, it is essential to pay attention to the sequence of actions and follow the company’s relevant regulations to prevent secondary accidents from occurring due to haste. 5. After a equipment accident occurs, it is necessary to report it to higher-level management promptly, strengthen measures to control risks, and further improve the equipment management system to ensure the long-term stable operation of the equipment. At the same time, it is necessary to maintain good communication and coordination with relevant departments in order to work together to solve problems and ensure that accidents are dealt with promptly and properly. 6. After each equipment accident occurs, an accident report and analysis should be conducted to summarize experiences and lessons learned, and effective measures should be taken to improve equipment management levels and reduce the occurrence of accidents. .

Are there any specifications and standard requirements regarding equipment turning?

I’ve learned it. Are there any specific operating procedures? handshake
