Winter Vibration Problems on VS6 Booster Pumps and Solutions
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Background: Three multistage canned vertically-suspended pumps are installed at Kerrobert, Canada to transfer crude oil. The pumps are driven by 1000 HP vertical motor at 885 RPM. Problem Statement: The installed pumps ...
Solving a Sever Vibration Problem in the Downstream Piping of a Gear Pump
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
A solution was developed for an extreme discharge piping vibration problem on an 80 hp gear pump piping system. Maximum field-measured vibration levels were over 4 ips 0-pk (200 mm/sec pk-pk). Most gear pumps are not ...
Using engineered composite materials in sealless magnetic drive pumps to eliminate eddy currents and improve reliability
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Background - Pump application: This case study is based on an application supplied into a Polysilicon production facility. The purpose of the application is to pump Trichlorosilane (TCS) liquid into the production process ...
Thermal Load Effect on Vibration on a Reactor Feed Water Pump (FWP)
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Eliminating Damage of Retaining Rings by Using Redesigned "Profiled" Keys
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Retaining rings are used to locate pump impellers axially on the shafts of high speed, high pressure Siemens Delaval boiler feed pumps. Upon repairing and refurbishing the inner barrels, the retaining rings were found to ...
High Vibration Analysis of Eddy Current Drum Coupled Motor to a Vertical Centrifugal Pump : Solution Based on EMA, ODS and FEA
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The 35-year old pump station moves up to 43 MGD of raw wastewater to the city’s treatment facility via two 1,500-hp high-capacity pumps for wet weather flows. After the motors were refurbished in 2011, excessive motor ...
Potassium Carbonate Pump Failure : High Axial Movement due to Uncontrolled (unbalanced) forces
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
A multi stage pump 1.4 MW was in operation till 4 years, the pump stand still for mean period without any failure symptoms , all last measurements (casing vibration, pressure ,flow) was OK , when the pump operated again ...
Solving an Acoustic Resonance in Crude Oil Pump Internals
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Specific Problem: Crude oil pump piping system that had previously operated without problems experienced a failure resulting in a release of oil: Vibration increased when a new well was opened and the fluid properties ...
Improved Mechanical Seal Design for High Temperature/Light Slurry Applications
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Extracting hydrocarbon products in oil sand formations requires high pressure to drive fluid out of the formation and to move the products out to production. The pump models that fit this operating envelope are not common ...
