This document discusses equipment reliability engineering and ways to improve it. It defines reliability as the probability that equipment will function as required without defects or breakdowns. Low reliability leads to chronic equipment losses due to frequent failures. Reliability consists of inherent reliability from design and manufacturing and use reliability from operation and maintenance. Five factors that affect inherent reliability are identified: design, manufacturing, installation, operation, and maintenance. Improving use reliability requires studying optimal equipment usage, operator skills, and ensuring equipment and operators are well-matched. Both high operator capability and good equipment condition are needed for overall efficiency.
Short-term and long-term solutions can increase reliability, asset availability, utilization, quality and capacity, but they’re not easy or simple. Look at the barriers that hold a plant back.
The United States lose manufacturing jobs everyday, plants are shutting down, so what is the problem. Companies struggle to find the nonexistent “silver bullet” for increasing reliability and equipment performance while reducing costs. Short-term and long-term solutions can increase reliability, asset availability, utilization, quality and capacity, but they’re not easy or simple. Look at the barriers that hold a plant back.
First is the belief that a failure means the equipment is broken. That’s wrong. A true failure of an asset is when it no longer meets the function required of it at some known rate or standard. For example, if a conveyor that’s supposed to operate at 200 meters per minute can’t, it has failed functionally, thus affecting revenue.
Think about it. Process Reliability Failures create higher losses than Asset Reliability Failures so it is time we woke up to this problem.
Researches, designs and implements facility wide building security access control and video solutions that enhance and support TMH operational and business performance.

Reliability is associated with unexpected failures of products or services and understanding why these failures occur is key to improving reliability. The main reasons why failures occur include:
The product is not fit for purpose or more specifically the design is inherently incapable.
The item may be overstressed in some way.
Failures can be caused by wear-out
Failures might be caused by vibration.
Reliability, describes the ability of a system or component to function under stated conditions for a specified period of time
Reliability may also describe the ability to function at a specified moment or interval of time (Availability).

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. CONCEPT OF EQUIPMENT
RELIABILITY
Why do Equipment chronic losses arises and not decreases? The
reason is, in brief low equipment reliability. Reliability here means
the probability that facilities, equipment, and system will function as
required during a specified period under a given condition .can also
be termed the probability that no problems(defects or breakdown)
will occurs during given period. Low reliability leads to the
occurrence of failures or defects, because their occurrence cycle is
short ,the losses become chronic.
3. CLASSIFICATIONS OF RELIABILITY
Reliability consists of INHERENT RELIABILITY and the USE RELIABILITY
.The inherent reliability results from the design, becoming fixed at
the stage of design and manufacturing. The use reliability results
from the way the equipment is used ,arising poor usage condition or
method of use.
4. INHERENT AND USE RELIABILITY CAN
BE SUBDIVIDED AS FOLLOWS AND
OVERALL RELIABILITY WILL BE THEIR
CUMULATIVE PRODUCT.
INHERENT RELIABILITY
DESIGN RELIABILITY
MANUFACTURING RELIABILITY
INSTALLATION RELIABILITY
USE RELIABILITY
OPERATIONAL RELIABILITY
MAINTENANCE RELIABILITY
5. 1.DESIGN RELIABILITY
Steaming from design, their reliability is affected by the following
factor
Jigs /tools unmatched to parts shapes
Problems in the mechanism itself
Problems in the selection of parts
Problems in the detection of parts
Short parts life
6. 2.MANUFACTURING RELIABILITY
This reliability derives from poor manufacturing or assembly of parts
,i.e problem occur because of incomplete manufacturing/assembly of
parts. They are due to the following factors,
•Problems in the accuracy of parts size
•Problem in the parts shapes
•Problem in assembly arrangements
7. 3.INSTALLATION RELIABILITY
This reliability is affected by poor installation arrangements,
problems occur because of incomplete or improper installation due to
the following factors:
•Occurrence of vibration due to poor installation arrangements
•Insufficient levelness
•Incomplete piping/wiring/fittings due to poor installation
arrangements
8. 4.OPERATION RELIABILITY
This reliability is affected by poor operational behavior. They are due
to the following factor:
Operation errors
Setup and adjustment error
Lack of through preparation of basic condition
Use condition error
9. 5.MAINTENANCE RELIABILITY
This reliability affected by poor maintenance quality. Problem occurs
because of incomplete maintenance ,due to such factors as:
Parts replacement error
Poor assembly accuracy
10. STUDY ON THE MANNER OF USING
EQUIPMENT
Generally, problems resulting from poor USE RELIABILITYS are many
,while those from poor design reliability are few. When breakdown or
defects occur ,it is necessary to examine to which type of reliability
decline they are related. Low reliability is considered to arise because
research on the manner of using equipment is insufficient. This
research is essentially the study of the expertise in using the
equipment, consisting of technology for using the equipment
skillfully and to optimum effect.
11. To develop the technology for optimal us of equipment, research is
required on the conditions to be possessed by equipment to attain
better quality ,to raise the utilization ration(time ,speed),and to
enhance operability /maintainability ,and research on the basic
arrangement regarding the equipment proper and peripheral devices
to obtain best performance from the equipment. Technology for
skillful use of equipment necessitates research on the role of the
operator in operation, adjustment, detection and handling of
abnormalities to keep the equipment in an optimum state.
STUDY ON THE MANNER OF USING
EQUIPMENT
12. CONCLUSION
Even if the technology for optimum use of equipment is fairly
advanced ,problem occur if the capability of the operators who use
the equipment is insufficient, and they do not perform their work as
they should. Conversely, even if the operation skill of operators are
excellent and they perform their work properly, breakdown may
unavoidable if the equipment itself has the problems. In either case,
effectiveness will be halved. Therefore ,it is necessary for both
operator capability and equipment condition to be on the same level,
just like two opposing wheels on a car .only then overall efficiency
improvement of a MAN-MACHINE system become possible.
