1. Because the mechanical equipment is often in a good technical state, it can be put into work at any time, reduce the downtime, improve the mechanical integrity rate and utilization rate, reduce mechanical wear, extend the service life of the machine, reduce the cost of mechanical work and repair, and strengthen the safety of the machine. maintenance of equipment;
2. Mechanical maintenance follows the principle of “maintenance is more important, prevention is the main”, so that maintenance is punctual and mandatory, and the relationship between use, maintenance and repair is correctly handled. It is not allowed to use only without maintenance, and only repair without maintenance;
3. Each team should carry out the maintenance of various types of machinery according to the machinery maintenance procedures and maintenance categories, and must not delay without reason. In special cases, the maintenance can be postponed after the approval of the special engineer in charge, but generally it should not exceed half of the regular maintenance interval;
4. The quality of the maintenance machinery should be carried out item by item according to the rules and requirements, and must not be missed or not guaranteed. Maintenance items, maintenance quality and problems found in maintenance should be recorded and reported to the specialists of this department;
5. Maintenance personnel and maintenance departments should achieve “three inspections and one handover (self-inspection, mutual inspection, full-time inspection and one-time handover qualification)”, constantly summarize maintenance experience, and improve maintenance quality;
6. The asset management department punctually supervises and inspects the mechanical maintenance status of each unit, checks the maintenance quality on time or not, and rewards the good and punishes the bad. The power device of the energy-saving speed-regulating mechanical equipment mainly comes from the AC motor, and when the motor is started, the current will be 5-6 times higher than the extra, which will not only affect the service life of the motor but also consume more electricity. There will be a margin in the selection of the motor. The speed of the motor is fixed, but in actual use, it is sometimes necessary to work at a lower or higher speed. In this case, an SAJ inverter is generally installed to complete the soft start of the motor, achieve the purpose of energy saving and speed regulation by changing the input voltage and frequency of the equipment, and provide the equipment with overcurrent, overvoltage, overload and other maintenance functions.
