在制订设备大修计划时,需合理确定计划停机天数。根据上次大修的停机天数及大修时间递增系数k,可得出该次大修的计划停机天数。该值可作为最终确定大修停机天数的重要依据。 设备大修因并未改变设备的原有结构,也未提高其固有可靠度,且用户厂的大修技术往往不如制造厂的制造技术,所以大修后设备质量和可靠程度较出厂水平有逐次下降的趋势。在正常情况下,对同一台设备,假设大修周期不变,欲使设备质量和可靠度恢复到原来的水平,
When formulating the equipment overhaul plan, it is necessary to determine the planned downtime reasonably. According to the last overhaul of the number of downtime and overhaul time increasing factor k, can be drawn that the overhaul of the planned number of days downtime. This value can be used as the final basis to determine the number of days of overhaul and downtime. Equipment overhaul has not changed the original structure of the equipment, nor did it improve its inherent reliability, and the user plant overhaul technology is often not as good as the manufacturer’s manufacturing technology, so after the overhaul of equipment quality and reliability than the factory level has a declining trend . Under normal circumstances, the same equipment, assuming the same overhaul cycle, to make the equipment quality and reliability returned to its original level,
