Reverse Engineering

Finding replacement metal bellows components is easier with Servometer's time saving reverse engineering guidelines. Download White Paper Reverse Engineering guidelines Today's design engineers often find themselves in the uncomfortable predicament of replacing legacy parts or parts that have become obsolete. This predicament is often the result of undocumented drawings, part numbers, or specifications. In many cases, the original designer is no longer available. Whatever the reasons, it is often the job of the design engineer to propose a solution using outdated technology and resources or insufficient information. This paper offers hands on reverse engineering guidelines and provides a solution to finding the ideal replacement bellows for your application.

Electroforming Basics

Electroforming is the process of depositing thin layers of metal onto a mandrel through electroplating, dissolving the mandrel chemically, and leaving the plating as the final electroformed product. Learn how electroformed components are manufactured and how they can be applied to a variety of applications.

The Basics Of Pressure Regulators

Pressure regulators are found in many common home and industrial applications. For example, pressure regulators are used in gas grills to regulate propane pressure, in home furnaces to regulate natural gas, in medical/dental equipment regulate oxygen and anesthesia gases, in pneumatic automation systems to regulate compressed air, in engines to regulate fuel pressure, and in fuel cells to regulate hydrogen. Although the applications vary considerably, the pressure regulators provide the same function. Pressure regulators reduce a supply pressure to a lower outlet pressure and they maintain this outlet pressure regardless of inlet pressure fluctuations. This reduction in pressure is the key characteristic of pressure regulators; outlet pressure is always at a pressure below the inlet pressure.

Advanced Symbolic and Numeric Techniques for Machine Vibration Analysis

The operational reliability of a rotary equipment train is dependent on the vibration of its components. Often, the only evidence of this vibration is gear noise or coupling wear. However, these early indicators might eventually develop into high-amplitude vibration, resulting in gear wear, gear tooth failures, or broken shafts. The torsional response characteristics of rotating and reciprocating equipment should therefore be analyzed and evaluated to ensure system reliability.

Bearing selection for low-speed applications

Low-speed applications present design challenges for bearings, just as high-speed applications do. (Uneven wear from intermittent motion, torque uniformity and vibration resistance are a few examples.) A new white paper from Kaydon Bearings, an SKF Group company, looks at the type of bearings typically used in low-speed applications and reviews 10 key performance requirements designers should consider when specifying them.

Unique Method for Orifice Production

To produce accurate, repeatable orifices, all the variables that might influence the Cd Value (Coefficient of Discharge) must be controlled during production. This includes the orifice hole length, edges, surface finishes, roundness and the elimination of all tool marks, burrs, ragged edges and irregularities. If any one of these areas is not perfectly managed, the orifice flow rates will vary from piece to piece thereby making it impossible to predict flow with any accuracy.
