Numerical Prediction Of Cavitation In Pumps
(Texas A&M University. Turbomachinery Laboratories, 2001)
With the increase in power per unit of volume for modern pumps, driven by manufacturing costs reduction, cavitation becomes more and more the main limiting factor in pump design. The classical one-dimensional design rules ...
Seal Reliability And Performance Improvements In A Large, High Pressure, High Temperature Barrel Pump
(Texas A&M University. Turbomachinery Laboratories, 2001)
Modifications to a high-pressure, high-temperature barrel pump to increase seal reliability and throughout are discussed. The pump is in unspared hydrodewaxer (HDW) feed service. The original seal design included nonpressurized ...
The Rotordynamic Integrity Of A New Machine - Vertical Hydraulic Turbine In Cryogenic Fluids
(Texas A&M University. Turbomachinery Laboratories, 2001)
This paper presents the rotordynamic characteristics of a vertical submerged hydraulic turbine generator obtained during design, manufacturing, shop testing, and site testing. The hydraulic turbine represents a new design ...
Reducing Life-Cycle Costs For Pumps Handling Cryogenic Fluids
(Texas A&M University. Turbomachinery Laboratories, 2001)
Advancements in the science of sealing technology have had a dramatic effect in increasing equipment reliability and reducing the cost of equipment ownership. One such area of success has been the pumping cryogenic fluids ...
Improving The Reliability And Performance Of A Melt Pump Application In A Petrochemical Plant With Block Style Universal Joints
(Texas A&M University. Turbomachinery Laboratories, 2001)
A major chemical company has implemented a cost reduction and performance enhancement via universal joints on a melt pump application. The melt pump is used to push molten polyethylene through a die to produce pellets. The ...
Nuclear Waste Transfer Pump - Design, Analysis, Testing, And Operation
(Texas A&M University. Turbomachinery Laboratories, 2001)
There was a time when people worked on radiologically contaminated equipment with a low level of protection, when equipment leakage was considered unavoidable, and when contaminated equipment was disposed of with little ...
Developing Fixed-Fee Seal Agreements To Improve Pump Reliability
(Texas A&M University. Turbomachinery Laboratories, 2001)
Long-term contractual agreements between a mechanical seal supplier and an end-user have proven to be a very effective method for improving equipment reliability. Successful agreements change the focus of a user/supplier ...
Mass Customized Design And Manufacturing System Of Advanced Hydraulic Parts
(Texas A&M University. Turbomachinery Laboratories, 2001)
This paper describes a production system for hydraulic parts. The system allows the rapid development and fabrication of hydraulic parts for custom-made pumps through the integration of innovative means and the positive ...
Development Of A Smart Pumping System
(Texas A&M University. Turbomachinery Laboratories, 2001)
In today’s global economy, process plants are under constant pressure to reduce costs. Users can no longer afford their attempts to make pumps bulletproof by upgrading component specifications. The development of a smart ...
Principles And Application Of A Diagnostic System For Mechanical Seals
(Texas A&M University. Turbomachinery Laboratories, 2001)
It is well known from long-term experience that life-cycle costs of a pump are determined by the consequential cost associated with pump failures. The failure of a pump, often originating from system-related nonpermissible ...
