Maintenance of mechanical equipment

1 Maintenance principles and requirements

1.1 In order to ensure that the machinery and equipment are always in good technical condition and can be put into operation at any time, reduce the downtime, improve the integrity and utilization of the machinery, reduce the wear and tear of the machinery, extend the service life of the machinery, reduce the operation and maintenance costs of the machinery and ensure safe production, it is necessary to strengthen the maintenance of the machinery and equipment;

1.2 The maintenance of machinery must follow the principle of "paying equal attention to maintenance and putting prevention first", achieve regular maintenance and mandatory maintenance, correctly handle the relationship between use, maintenance and repair, and it is not allowed to use only without maintenance, only repair without maintenance;

1.3 Each team must do a good job in the maintenance of all kinds of machinery according to the machinery maintenance procedures and maintenance categories, without unreasonable delay. In special cases, the maintenance can be extended only after the approval of the special engineer in charge, but generally not more than half of the specified maintenance interval;

1.4 The maintenance of machinery shall ensure the quality, and shall be carried out item by item according to the specified items and requirements, without missing or missing the warranty. The maintenance items, quality and problems found in the maintenance shall be recorded and reported to the special engineer of the department;

1.5 The maintenance personnel and the maintenance department shall implement "three inspections and one handover (self-inspection, mutual inspection, full-time inspection and one handover)", constantly summarize the maintenance experience and improve the maintenance quality;

1.6 The Asset Management Department shall regularly supervise and inspect the mechanical maintenance of each unit, regularly or irregularly check the maintenance quality, and reward the good and punish the bad.

2 Implementation and supervision of maintenance work

2.1 The mechanical maintenance shall adhere to the "cross" operation method with "cleaning, lubrication, adjustment, fastening and corrosion prevention" as the main content, implement the routine maintenance and regular maintenance system, and strictly follow the cycle and inspection and maintenance items specified in the operation manual.

2.2 Routine maintenance refers to the cleaning and inspection carried out before, after and during the operation of machinery, mainly checking the condition of key and vulnerable parts (such as mechanical safety device), coolant, lubricant, fuel quantity, instrument indication, etc. The routine maintenance shall be completed by the operators themselves, and the Mechanical Routine Maintenance Record shall be filled in carefully.

2.3 Level I maintenance: generally carry out cleaning, fastening and lubrication operations, and partially carry out adjustment operations to maintain the technical condition of the machinery. According to the maintenance plan, the asset management personnel of the user unit shall issue the Notice on Maintenance and Lubrication of Mechanical Equipment to the operation team, which shall be completed by the operator himself and inspected and supervised by the head of the operation team.

2.4 Second-level maintenance: it includes all the contents of first-level maintenance, focusing on inspection and adjustment, to keep the mechanical assemblies, mechanisms and parts in good working performance. The asset management personnel of the user unit shall issue the Notice on Maintenance and Lubrication of Mechanical Equipment and issue it to the operation team, which is mainly completed by the operator himself. If the operator has difficulty in completing it, he can entrust the repair department to carry out it. The asset manager of the user unit and the head of the operation team shall inspect and supervise
