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 ...
Upstream Pumping: New Developments In Mechanical Seal Designs
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Conventional mechanical seals are arranged to prevent leakage from a high pressure source. When leakage occurs, it is expected to be from the high pressure area to the lower pressure surroundings. The basic concept of the ...
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 ...
Establishing An Electric Motor Lubrication Program (Unpublished)
(Texas A&M University. Turbomachinery Laboratories, 2007)
Mechanical Seals With Wavy Sic Faces For A Severe Duty NGL/Crude Pipeline Application
(Texas A&M University. Turbomachinery Laboratories, 2004)
Mechanical seals were developed for a pipeline with demanding operation conditions. Natural gas liquids (NGL), refined products, and crude oil are pumped in batch mode. Seal pressure varies over a wide range and the pumps ...
Multistage Pump Efficiency Gains Through The Elimination Of The Seal Chamber Pressure Equalization Line
(Texas A&M University. Turbomachinery Laboratories, 2004)
The majority of horizontally split multistage pumps were designed when packing was the only cost effective method of sealing the pumpage from atmosphere. As a result, even modern pumps employ a stuffing box pressure ...
Dry Gas Sealing Systems For Oil Sands Pumping Applications
(Texas A&M University. Turbomachinery Laboratories, 2005)
Power Pump Valve Dynamics
(Texas A&M University. Turbomachinery Laboratories, 2009)
The dynamics (movement) of the check valves in a reciprocating power pump determine whether the pump will operate quietly and smoothly, or noisily with pulsation and vibration. Although piping pulsation and vibration are, ...
Dynamic Improvement Of An Overhung Single-Stage Pump
(Texas A&M University. Turbomachinery Laboratories, 2009)
Vibration control is an important aspect of all pump design. It helps assure quiet operation and high reliability. Therefore, the design of pump components should avoid any dangerous resonances with excitation forces, such ...
