FMEA Video: How To Perform a Failure Mode and Effects Analysis

FMEA stands for Failure Mode and Effects Analysis. This DMAIC tool is used to evaluate risk in a process. FMEA will help to improve the quality and safety of work tasks. Using this SigmaXL template will allow you to document a baseline for improvement and provide compelling data to confirm a need for changes to the current process. Detection level is critical to quantify the cost of poor quality.

You would never want to pass on a defect to a customer or create an environment that puts employees at a risk of injury. FMEA encourages a proactive approach when used to assess risk in newly designed products or processes. This tutorial demonstrates how to use SigmaXL software to record before and after risk levels. View video for more information on this technique.

FMEA is an acronym for Failure Mode and Effects Analysis. This video tutorial will teach you what is a Failure Mode and Effects Analysis, when to use FMEA, and show you a template available with SigmaXL software.

The goal of FMEA is to identify, quantify, evaluate and prioritize risk in a process. The risk may be present due to human error, or a lack of controls in a computer process. Ultimately, we want to reduce the possibility of the risk negatively impacting the customer or an employee. It is important to track your risk assessment in your DMAIC project and ensure that the implemented solution addresses possible failure modes. Your control plan should include actions to take if the risk is detected. Video presented by Lean Six Sigma

5 Important Maintenance Metrics and How To Use Them

By Bryan Christiansen, Limble CMMS. Source : maintworld.com Effective maintenance of equipment is a critical factor in delivering quality operations that provide timely resources at a minimal cost. However, those in the maintenance field understand that equipment reliability does not come easy. Organizations need to set quality benchmarks to measure the current effectiveness and predict future performance and use the data obtained to understand where to make improvements. One way to do this is by using different maintenance metrics to understand the equipment performance. These metrics are very important as they can mean the difference between achieving the overall business goals and explaining how unexpected breakdowns caused yet another production delay. Maintenance Metrics You Should Be Measuring What are the maintenance metrics? There are two categories of maintenance key performance indicators which include the leading and lagging indicators....

Grounding brush discharge monitoring

In recognition of the possibility of static charge build up in condensing steam turbines, API 612 (2005) specifies that grounding brushes be installed. The electrical flow to ground through these brushes be monitored and useful information can be extracted. This article carries excerpts from the paper, “Babbitted bearing health assessment” by John K Whalen of John Crane, Thomas D Hess of Chestnut Run, Jim Allen of Nova Chemicals and Jack Craighton of Schneider Electric. Grounding brushes take current from the rotor to ground so that a charge does not build up on the rotor to the point where it discharges to ground though the best path possible – which is usually the closest point between the rotor and stator which is usually (hopefully) the point of minimum film thickness in a bearing. Typically this point of minimum film thickness is found in the active thrust bearing (as will be shown later). Shaft grounding brushes serve two purposes. The brushes are able to transmit modest amo...

WHAT IS THE ULTRASONIC IN-LINE INSPECTION (ILI) PIGGING?

In-line inspection (ILI) of pipelines has established itself as the most efficient tool for evaluating the condition of a pipeline and an indispensable part of pipeline integrity management. Historically, there have been two major technologies used in in-line inspection for corrosion, the magnetic flux leakage (MFL) and ultrasonics (UT), each having their distinct properties and fields of application. Ultrasonic (UT) ILI has always provided unique quality of information about the pipelines, rendering highest accuracy and tightest measurement tolerances. In the 1990s ultrasonic tools for detection of cracks have become available. Ultrasonic measurement principle: ultrasonic transducer slides along the internal surface of the pipe wall measuring distance to the wall and the wall thickness (top), yielding the stand-off and the wall thickness (bottom two B-scans) Ultrasonic (UT) based In Line Inspection tools for all types of liquid filled pipelines. This includes Ultras...

Why Pump Shafts Often Break at the Keyway Area

By NTS Pump shaft failure can lead to significant downtime and repair costs in industrial plants. One of the most common locations for pump shaft failure is at the keyway area. In this article, we will explore the reasons why pump shafts often break at the keyway and what can be done to prevent such failures. The keyway is a high-stress point (weakest point) on the shaft, where a key is inserted to transmit torque between the shaft and the pump impeller or coupling. During operation, the keyway experiences cyclic loading that creates a bending moment in the shaft, which is concentrated in the keyway area. Over time, this cyclic loading can cause fatigue failure in the shaft material, leading to a fracture at the keyway. In addition to cyclic loading, other factors can contribute to shaft failure at the keyway. Improper keyway design or installation can lead to stress concentrations or inadequate clearance between the key and keyway . Misalignment or overloading can also cause ex...

Pump Shaft Breakage: Case Studies and Solutions

By NTS Pump shaft breakage is a common issue that can cause costly downtime and repairs in various industries. In this article, we will explore several case studies of pump shaft breakage and the solutions implemented to prevent future failures. Case Study 1: Chemical Processing Plant A chemical processing plant experienced repeated pump shaft breakages in their cooling water pumps. Investigation revealed that the pumps were not properly aligned with the motor and had excessive vibration due to the misalignment. This caused the pump shaft to fatigue and break over time. The problem was resolved by realigning the pumps and installing vibration monitoring equipment to detect any future misalignment or excessive vibration. Case Study 2: Wastewater Treatment Plant A wastewater treatment plant had issues with pump shaft breakage in their sludge pumps. The pumps were designed with a straight shaft and lacked a flexible coupling, causing excessive stress and vibration on the pump sha...
