预防性维护和预测性维护之间的区别

1. 预防性维护：
预防性维护，顾名思义，是一种预防措施，用于防止将来发生任何意外故障。其主要目的是找出最初很小但可能导致重大问题的问题。之后，在出现重大问题之前解决它。

2. 预测性维护：
顾名思义，预测性维护是一种预测性操作，用于通过在资产运行时简单地检查资产来识别可能发生的资产潜在故障。在预测性维护中，可以确定何时需要维护资产，以避免不必要的投资和维护。

预防性维护和预测性维护之间的区别：

Preventive Maintenance	Predictive Maintenance
Preventive maintenance is usually performed to prevent assets from unexpected failures.	Predictive maintenance is usually performed to predict failures that might occur so that it can be prevented from occurrence.
This maintenance is performed on whether needed or not i.e. whether potential failure is identified or not. This is done on regular basis.	This maintenance is performed whenever needed i.e. whenever any potential failure is identified. This is not done on regular basis.
One needs to increase downtime of asset to carry out maintenance i.e. one need to stop primary functions of assets to carry out maintenance action.	No downtime of machine is required i.e. one does not need to stop primary functions of assets as this maintenance can be performed while assets are performing their regular functions.
In this, maintenance occurs even if potential failures are not identified.	In this, maintenance occurs only when potential failures are identified.
It is less complex process and simple than predictive maintenance.	It is more complex and difficult than preventive maintenance.
This maintenance action is more costly than predictive maintenance as regular maintenance requires more investment.	This maintenance action is less costly than preventive maintenance as one can simply reduce avoid maintenance that is not necessary and thus reduce maintenance costs.
It is more time consuming because in this type of maintenance, one need to perform inspection and maintenance on regular basis.	It is less time consuming as in this type of maintenance, one need to perform inspection and maintenance only when required.
