Elements of An Effective Maintenance Management System


An effective maintenance system includes the following elements:

  • Maintenance Policy
  • Control of materials
  • Preventive Maintenance
  • Condition Monitoring
  • Work Order
  • Job planning
  • Priority and backlog control
  • Data recording system
  • Performance measurement measures or indices

Maintenance performance for a plant or an organization can be assessed through analysis of Reliability, Availability and Maintainability (RAM) plant data. Relevant parameters, measures or indices for specific plants can be identified. The performance over a period of time will show if it is improving, going down or being sustained. This will also help in knowing how well the objectives are being met. In addition, it will guide the areas which are strong and which need to be strengthened. Use of computers and dedicated software will certainly help in implementing this and the maintenance management system in general.

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...

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...

Preventing Motor Bearing Damage from Shaft Current with the AEGIS® Ring

Electric motors are the workhorses of modern industry, powering everything from pumps and fans to conveyor belts and heavy machinery. But these vital components are not immune to wear and tear, and one common problem that can lead to premature motor failure is bearing damage caused by shaft current. Shaft current is a type of electrical discharge that occurs when there is a voltage potential between the motor shaft and the bearing, resulting in the flow of electrical current through the bearing. This current can cause a range of problems, including pitting and fluting of the bearing surfaces, which can lead to premature wear and failure. Shaft current Motor shaft current can have several harmful effects on bearings, including: 1.      Bearing pitting and fluting: Electrical discharges can cause tiny pits and flutes to form on the bearing surfaces, leading to premature wear and failure. 2.       Bearing noise and vibration: Shaft current can cause ...

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....

The 7 guiding principles of a Maintenance 4.0 strategy

Formulating a digital strategy is not easy, but these guidelines can help you get off the sidelines and into the game. By Eitan Vesely and Deddy Lavid (Ben lulu), Presenso It is not uncommon for organizations to struggle with many issues related to digitalization. With the hype around digitalization at fever pitch, it is easy to become overwhelmed by the multitude of options available in the marketplace. But the strongest contributing factor to implementation challenges is a failure to devise a strategy for an extensive period of uncertainty. Formulating a Maintenance 4.0 strategy is not easy. An aggressive strategy based on overinvesting in unproven technologies or a conservative strategy of merely waiting on the sidelines are unrealistic options. Guiding principles The seven guiding principles for a Maintenance 4.0 strategic plan are: 1. Invest based on the business case The primary obligation to shareholders does not change just because of the changes occurring within t...
