Optimizing Industrial Equipment: Reliability, Availability, and Maintainability
Safety and Equipment Management
Safety Plan (Human):
Availability: Plan technical reliability, maintainability, productivity, durability (technical-economic Plan)
Costs: (planeconómico-Direct: (preventive or corrective)-Indirect: (for damage)
Inventory: Nomenclature encoded to maintain the park, established by logic tree-family groups.
Dossier-machine: It allows the knowledge of a team source, its technologies, and behaviors. 2 parts:
- Event of the builder: Provided documents and contractual correspondence.
- File internal machine: Standard, established and maintained by methods.
The history of machine (in the dossier): Ichera inventoried on each machine that chronologically describes corrective intervention from its commissioning. Represents the “card Health.”
Exploiting data: 5 levels, holdings for:
- Reliability
- Availability
- Methods and times
- Managing stock
- Establish political mantle
Qualitative Method: Evaluation by Criteria
1. Criterio intrinsic material: Complexity of technology. (CT) level 1: simple. 2: complex. 3: very complex.
2. Criterio of operation: The most important: Importance of computer in the production process. (IP) grade: 1: secondary. 2: main. 3: vital Operation. (F) the 2nd most important, grade 1: sporadic. 2: intermittent. 3: continued.
3. Criterio maintenance: Direct maintenance costs. (CD) grade 1: low. 2: means. 3: high
4. Criterio economic: Value replacement for an identical one. (VR) degree: 1: inexpensive. 2: costs o. 3: very expensive indirect costs for lost production. (IQ) level 1: low. 2: means. 3: elevated from 2.50 to 3.00 A or critical area. From 1.50 to 2.50 in Zone B or half. From 1.00 to 1.50 or lower zone C
Quantitative Method: ABC or Pareto Chart
Shows between several priority issues over the 2 graphs in one:
- One bar: It will represent the probability on the total of each of the parameters on the machine.
- Another nonlinear: Represents the cumulative frequency or probability, to determine or to segment the different areas of criticality.
Bug: Alteration or interruption of a well in compliance with a required function of the rule simplified
Excerpt:
Nigeria:
- Partial: Disturbance operation
- Completed: Cessation of operations.
- Cataleptic: repentinoycompleto
- For degradation: Gradual and partial.
- Random: Constant failure rate. Pure electronic product
- From wear: Increasing failure rate. Electromechanical or mecánico.
LA failure rate is an estimate of RELIABILITY AND REPAIR RATE OF availability and maintainability
Can define 3 stages in the life span of a youth team:
- Mortality (early failure)
- Maturity (period of life, random failures)
- Obsolescence (aging, wear)
Availability “the probability that the device is in working condition”, i.e., that is not ‘damaged or review. Availability depends on the reliability and maintenance.
Maintainability “the probability that the device is placed after the failure in a given operating condition and at a given time, is characterized by the MTTR.
Maintainability criteria to consider before purchasing an industrial equipment are related Criteria with the conception of a good (Acquisition of a machine I) Criteria for Criteria for the monitoring information by the SPV (Post Sales) Criteria for Reliability user management likelihood that this device meets a required role in the conditions use for which it was designed and in a period of time IF MTBF RELIABILITY ? ? ?
