Our supervisor asked me to write down methods for maintaining the operating equipment, so that these can be posted as signs in the control room to help operators keep their responsibilities in mind. Unfortunately, we lack experience in this area; we would appreciate it if experts could offer their help. The equipment in question includes centrifugal pumps, plunger pumps, and CO2 compressors. By the way, if anyone in our urea production workshop has relevant information, please share it with us – we would be very grateful!!

For the workers and technicians working on the front line, to achieve a true integration of humans and machinery, it is necessary to pay close attention to every detail of the equipment under their responsibility. This requires them to have a thorough understanding of the equipment in terms of its structure, performance, principles, and applications – in other words, to achieve the ‘four understandings and three abilities, three excellences’; Able to operate, maintain, and troubleshoot ; Use it well, manage it well, maintain it well. For the on-site maintenance of the equipment under one’s responsibility, it is necessary to adhere to the principle of \"three frequences and one certainty\": frequent inspections, frequent cleaning, regular maintenance, and accurate recording at set intervals. When conducting on-site inspections of the equipment under one’s responsibility, it is necessary to follow the five-step inspection method of \"listening, touching, smelling, comparing, and observing.\" During these inspections, three essential tools should be carried: a wrench (for tightening), a rag (for cleaning), and a listening rod (for detecting noises). The operation of equipment must adhere to the \"four no’s\" (no overheating, no overpressure, no excessive vibration, no overload) and the \"four no-leaks\" (no water leakage, no air leakage, no oil leakage, no liquid leakage). Ensure that the equipment site meets the requirements of \"one level, two clean, three visible, four absent, five not lacking\": the ground should be level, the doors and window glass should be clean, the surrounding walls should be clean, the ditches should be bottomless, the shafts should be visible, and the equipment should show its original color. There should be no garbage, weeds, waste materials, or unnecessary equipment. Additionally, there should be no shortage of insulation materials, bolts or handwheels, doors or window glass, light bulbs or lampshades, nor floor grates.

Article 45: Provisions for routine inspections under the pump equipment package system: 1. Inspection contents: (1) The temperature and vibration of the bearings at various speeds of the pump (including the motor), as well as checking for any abnormal noises. (2) Temperature, pressure, and flow rate at the inlet and outlet of the medium. For most compressors, it is necessary to check the data for each stage. (3) Leakage conditions at each seal. (4) The inlet and outlet temperatures, pressures, and flow conditions of systems such as lubricating oil, sealing oil, and cooling water. (5) Listening inspection of the pump casing, frame, and all moving parts of the machine (including intake and exhaust valves). (6) Current value of the matching motor. (7) Indication values of the instruments in the pump station control room and at the site. (8) The speed of the turbine and the pressure and temperature of the control oil. (9) Oil level and color of the lubricating oil. (10) Is the governor sensitive? 2. The inspection intervals and recording requirements are as follows: Inspection Type A, B, C – Personnel: Inspection record, Inspection record, Inspection record. Operators: Every 2 hours, once per shift, once per shift, once per shift, once per shift, once per shift. Maintenance staff: Once a day, once a day, twice a week, twice a week, twice a week, twice a week. Management staff: Twice a day, once a day, once a day, once a day, twice a week, twice a week. Note: Twice a day refers to once in the morning and once in the afternoon ; Twice a week, with an interval of 2 to 4 days. Forty-six: In addition to meeting the relevant provisions on equipment maintenance management outlined in Chapter 4, emergency repairs of various types of pumps during production must comply with the rules specified in the table below: Category A pumps, Category B pumps, Category C pumps – Time: Continuous repair until normal operation is achieved. Overtime is generally not required, but weekend rest days are excluded (in the event of a failure in the backup unit, it is treated as a Class A pump). To be agreed upon by the workshop equipment officer and the maintenance unit. Test run verification: workshop equipment staff, personnel from the Equipment Power Department, section chiefs (or quality inspectors) in charge of maintenance, operators, and maintenance technicians. Workshop equipment operator, maintenance section leader (or quality inspector), operators, and maintenance workers. Workshop equipment technicians, maintenance staff, operators. Maintenance records, quality inspection form signatures: workshop equipment officer, relevant personnel from the Equipment Power Department, and maintenance section leader. Workshop equipment technician, maintenance shift leader (or quality inspector). Production team leader, maintenance staff. Article 47: Maintenance: 1. The maintenance of various types of pumps is primarily the responsibility of the operators, with the assistance of maintenance staff. Equipment maintenance should be carried out in accordance with the ten-step approach of “cleaning, lubrication, tightening, adjustment, and corrosion prevention” to ensure proper use and careful upkeep. This will help maintain the good performance of the pumps, keep their appearance neat, and ensure that all components are intact and undamaged. The equipment and its surrounding area should be free from dirt, rust, defects, disorder, or leaks. 2. Turning of various types of pumps and motors: Clear color markings should be applied to the shaft or coupling for identification, and records should be kept. 3. For the main equipment in Class A pumps, spectral analysis is conducted every six months, and lubricant sampling analysis is carried out every six months. Others: For standby pumps, pumps without interlocks are switched over once per quarter. The interlocked standby pump is started manually once per quarter. There are also written records stating that for rotating equipment with turbines as drives (except for critical units), an overspeed test must be conducted within one year of operation, with records of the tripping speed kept.

For specific equipment maintenance, refer to the equipment’s user manual. Below is a equipment maintenance management system; I hope it will be helpful to you. Equipment Maintenance Management System: This system is established to strengthen the maintenance of equipment, implement the principles of \"prevention first\" and a combination of maintenance with scheduled inspections, ensure proper use and careful upkeep, keep the equipment in good condition at all times, and thus guarantee its long-term, safe, and stable operation. 1. Enterprises should actively carry out initiatives such as maintaining \"perfectly functional equipment\" and ensuring \"no leaks,\" implement a system of assigning specific responsibilities to each piece of equipment, and ensure that every piece of equipment, every pipeline, every valve, and every instrument has someone in charge of it. 2. Operators must use the equipment correctly and maintain it properly with a serious attitude and scientific methods. 3. Through on-the-job training and drills, operators must achieve a thorough understanding of the equipment they use and master the necessary skills; only after passing relevant examinations and receiving a certificate are they allowed to operate the equipment independently. 4. Operators must carry out the following main tasks: (1) Start and stop the equipment strictly in accordance with the operating procedures. (2) One must remain at post, strictly implement the routine inspection system, and carefully fill in the operation records. (3) Ensure proper equipment lubrication. (4) Strictly implement the shift handover system. (5) Keep the equipment clean and address any leaks or spills promptly. 5. If the operator notices any abnormality in the equipment, they should immediately investigate the cause and report it promptly. In emergency situations, decisive action should be taken or the vehicle should be stopped immediately, and the duty supervisor and relevant personnel should be informed. Driving should not proceed blindly without identifying the cause and ruling out any faults. Unresolved defects must be recorded in the operation log and clearly communicated to the next shift. 6. Maintenance workers (for machinery, electrical systems, and instrumentation) must have clear divisions of labor; they are responsible for maintaining the equipment assigned to them, and must ensure that: (1) inspections are carried out at regular intervals and in designated locations, and that they proactively inquire from operators about the operating conditions of the equipment. (2) Defects that are identified should be eliminated promptly. For those that cannot be removed immediately, they must be carefully documented, reported in a timely manner, and eliminated as part of the equipment maintenance process. (3) Complete the maintenance tasks in terms of quality and quantity. 7. All spare equipment should have dedicated personnel responsible for its regular inspection and maintenance. Attention should be paid to preventing dust, moisture, freezing, and corrosion. For transmission equipment, it is also necessary to carry out regular turning and switching operations to keep all spare equipment in good condition. 8. Workshop equipment managers should supervise and inspect the implementation of the equipment maintenance system, carefully summarize the maintenance experience of operators and repair workers, and improve equipment management. 9. The supporting equipment shall not be disassembled for use without the approval of the Equipment Power Department.

Which company do you work for? The quality of the operators at your company is much better than that at our company. Our company’s operators don’t even know how to turn valves on and off; when it comes to operating pumps, they just press buttons, and it is our maintenance staff who have to handle turning the valves on and off.

The above has covered a lot of content; there is even more regarding the standards. When preparing such documents, it is necessary to take into account the actual conditions of one’s own company, the characteristics of the equipment, and the general skill level of the operators, among other factors. This is for reference only!

Based on the process operation requirements, and by referring to the equipment manual, one can compile the operating procedures for the equipment required for their specific position.
Reply #152008-01-23
During the operation, attention must be paid to oil, gas, water, electricity, and so on. This should also be one of the qualities that operators must possess

The process engineers here really know nothing at all; they give useless instructions. Yet the management values them, and as a result, time is wasted every time. In the end, it’s us who have to do everything
