作为一个企业的管理者和工程技术人员 ,对企业所使用的设备除了要了解设备的的运转状况之外 ,同时更应了解设备何时要更新 ,对这些问题要认真对待 ,更新过早 ,老设备的生产潜力未得到充分的发挥而抛弃 ,造成损失 ;更新过晚 ,老设备生产效率低下 ,维护费用增加 ,也会造成损失 . As an enterprise manager and engineering technician, in addition to knowing the operating conditions of the equipment, the equipment used by the company should also understand when the equipment needs to be updated. These issues should be taken seriously, and the update should be too early and old. The production potential of equipment has not been fully exploited and abandoned, resulting in losses; late update, the old equipment production efficiency is low, maintenance costs increase, but also cause losses.
