Predicting And Improving The Dynamic Behavior Of Multistage High Performance Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
Good rotordynamic behavior, implying sufficient stability margin and low sensitivity to unbalance forces, is mandatory for modern high pressure multistage pumps. Stiffness, damping and mass matrices describing the forces ...
A Map Of The Forest .. Understanding Pump Suction Behavior: Where Do We Go From Here?
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
Coupling Applications for Special Purpose Machinery Multiple Flexible Membrane Types
(Texas A&M University. Turbomachinery Laboratories, 1984)
Special purpose machinery applications of flexible disc couplings with multiple convoluted diaphragms or disc packs at each end of the spacer are discussed. Couplings in this category were retrofitted on two compressor ...
Development of High Specific Speed Mixed Flow Compressors
(Texas A&M University. Turbomachinery Laboratories, 1984)
The results of a study on the aerodynamic performance of a high specific speed, mixed flow compressor are presented. The specific speed was N. = 450 to 550 (m³/min) ½ (rpm) (m⁻¾ ), with approximately a 2.0 pressure ratio ...
Torsional-Damping-Transient and Steady State
(Texas A&M University. Turbomachinery Laboratories, 1984)
Couplings play an important role in the solution of many turbomachinery torsional problems. Due to inherently high inertias, many systems have torsional natural frequencies in the units' operating range, and operational ...
Application of Single Membrance Type Flexible Power Transmission Couplings
(Texas A&M University. Turbomachinery Laboratories, 1984)
The purpose of a flexible coupling is to transmit torque from a driver to a driven machine. It is the responsibility of the application engineer to assure that the coupling selected will transmit this torque with a minimum ...
An Overview Of Cogeneration Technology - Design, Operation And Maintenance.
(Texas A&M University. Turbomachinery Laboratories, 1984)
The growth of cogeneration technology started in the 1960s, but has recently accelerated with several users interested in cogeneration applications. An overview of cogeneration technology is presented, with current experience ...
Design, Control And Startup Features Of Three Parallel-Working Propane Compressors Each Having Three Stage Groups.
(Texas A&M University. Turbomachinery Laboratories, 1984)
Two main problems must be solved in the planning and execution of compressor sets to be installed within refrigeration loops. The use of several compressors with different sidestream admissions calls for the installation ...
An Empirical Solution To An Anti-Surge Control Problem.
(Texas A&M University. Turbomachinery Laboratories, 1984)
Steps taken by a du Pont team to prevent surge in a 23,000 hp process air compressor are reviewed. The process has several reactors which must interlock down quickly for safety reasons. These interlocks can occur on one, ...
Metallurgical Failure Analysis - What, Why And How.
(Texas A&M University. Turbomachinery Laboratories, 1984)
When capital expenditures arc made for plant equipment, it is routine to anticipate that this equipment will meet reliability and performance expectations and will not experience untimely failure. Being realistic, however, ...
