Materials For Centrifugal Compressors - A Progress Report.
(Texas A&M University. Turbomachinery Laboratories, 1989)
Progress in materials for centrifugal compressors over the last twenty years is reviewed. Specific areas discussed include:
• Impeller materials and fabricating procedures.
• Shaft manufacture, processing, and testing.
• ...
Maximizing An Ethylene Plant's Turbomachinery Reliability.
(Texas A&M University. Turbomachinery Laboratories, 1989)
The ethylene plant in DuPont's major petrochemical complex
in Orange, Texas was designed and built in the late 1960s,
using the latest proven technology of that period. From plant
startup in 1967 to 1981, there were ...
Centrifugal Pump Hydraulics For Low Specific Speed Applications
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The hydraulic coverage in the low specific speed region has been ignored by most centrifugal pump manufacturers because of unfavorable hydraulic characteristics, and manufacturing obstacles such as small, difficult to cast ...
Dry Start Bearing For Vertical Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Compound bearings made of PTFE and synthetic rubber were developed for vertical pumps to startup without initial lubricating water. Through various experiments, they were clarified to be superior to any other bearings of ...
Table of Contents for the Proceedings of the 6th International Pump Users Symposium
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Heat Transfer In Mechanical Seals
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Numerous studies have shown that mechanical seal reliability is related to the state of the fluid between the seal faces. In turn, the fluid state depends on the seal face temperature. Unfortunately, calculating the seal ...
Reciprocating Pump Valve Design
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The working mechanism and life expectancy of automatic pump check valves, which are important for the operational safety of oscillating displacement pumps, are closely examined. A calculation process for the determination ...
Rolling Bearings In Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The primary considerations for the selection and application of rolling bearings in centrifugal pumps are discussed. These considerations apply to both the pump manufacturer and the pump user. The various types of bearings ...
An Evaluation of the Effects of Refrigerant Charge on a Residential Central Air Conditioner with Orifice Expansion
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M UniversityDepartment of Mechanical Engineering, Texas A&M University, 1989)
Recent studies have been conducted at Texas A & M
University to quantify the effect of over/undercharging on
the performance of a residential central air conditioner
with two different expansion devices: capillary tubes ...
Policy Recommendations for Establishing the LoneSTAR Monitoring and Analysis Program
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M UniversityDepartment of Mechanical Engineering, Texas A&M University, 1989)
The major objectives of the Monitoring and Analysis Program (MAP) should be to: Verify energy and dollar savings of the retrofits; Reduce energy costs by identifying operational and
maintenance improvements at facilities ...
