Evaluation Of Coatings For Resistance To Abrasive And Adhesive Wear In Pump Components
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
Long term pump efficiency and durability are directly related to the ability of materials of construction to resist various forms of wear. The need for resistance to both adhesive and abrasive wear is often greatest in ...
Analysis Of The Thermal Behavior In The Sealing Cavity Of An Overhung Api Process Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
In recent years, cooling requirements for mechanical seals have become a subject of controversial opinions. While the maximum limiting temperatures of mechanical seals are known and specified by seal manufacturers, the ...
ISO 5i99 Standard Addresses Today's Reliability Requirements For Chemical Process Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
The standards used so far by European manufacturers of chemical process pumps were only dimensional: ISO 2858, BS 24256, DIN 24256, NF E 44121. The pump manufacturer had total freedom of design provided outline dimensions ...
Sintered Alpha Silicon Carbide Pump Bearings - Tribological Materials Optimization To Improve Reliability
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
The material properties of sintered silicon carbide, such as universal corrosion resistance, hardness, strength, and thermal conductivity, offer a great potential as sealless pump bearings and mechanical seal faces. In ...
Using Fault Trees To Determine The Root Cause Of Rotating Equipment Failures
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
The great value of using multidisciplinary task groups to conduct root cause failure analyses (RCFA) on pump and rotating equipment failures is discussed. The RCFA method offers its users a structured means of achieving ...
A Case History - Improvements To An Existing Cooling Tower Sump And Horizontal Split Case Pumps
(Texas A&M University. Turbomachinery Laboratories, 1999)
In adding a second urea plant in 1974 at a Midwestern nitrogen plant, higher cooling water requirements necessitated the construction of an additional cooling tower. A 130 million Btu/hour cooling tower was installed with ...
How To Justify Machinery Improvements Using Reliability Engineering Principles
(Texas A&M University. Turbomachinery Laboratories, 1999)
For the typical machinery engineer, the difficulties encountered with making reliability improvements lie not with the “mechanics” of improvements, but with justifying the cost of improvements. It is difficult to translate ...
A Cavitation Resistant Hydrostatic Seal For High Pressure Breakdown
(Texas A&M University. Turbomachinery Laboratories, 1999)
A unique hydrostatic throttle bushing concept has been developed and successfully tested. The throttle bushing is based on the concept of typical hydrostatic face seals, but incorporates improvements to minimize cavitation ...
Low Cost Reliability Through Operator Involvement
(Texas A&M University. Turbomachinery Laboratories, 1999)
At most industrial facilities, the engineering, maintenance, and operation groups are under great pressure to increase reliability and also reduce costs. This paper discusses the role of operators in achieving low cost ...
Selection Of Lube Oil Systems Components For Process Pumps And Auxiliaries (External, Pressurized)
(Texas A&M University. Turbomachinery Laboratories, 1999)
Lube oil systems are utilized in rotating process equipment to lubricate and cool hydrodynamic bearings. These systems are essential to the life and maintenance free operation of the process equipment. Dependable performance ...
