Abstract

Se proveen técnicas para poner a punto una bomba de desplazamiento positivo de dos husillos que tienen un procesador de señales para recibir señalización que contiene información acerca de datos reales del desempeño de la bomba para condiciones nominales reales capturadas durante una función de puesta a punto relacionada con la operación de la bomba de desplazamiento positivo de doble husillo y determinar datos corregidos del desempeño de la bomba para poner en operación la bomba rotativa de desplazamiento positivo al compensar los datos de desempeño de la bomba usados para poner en operación la bomba de desplazamiento positivo de doble husillo con base en datos reales del desempeño de la bomba para las condiciones nominales reales capturadas durante la función de puesta a punto. Los datos corregidos del desempeño de la bomba incluyen datos corregidos del desempeño de la bomba publicados que tienen una potencia y factor de deslizamiento nominal publicados corregidos y los datos reales del desempeño de la bomba contienen información acerca de la potencia, gravedad específica y viscosidad reales relacionadas con la operación de la bomba de desplazamiento positivo de doble husillo y recibidos de un controlador de la bomba, que incluye una unidad de frecuencia variable.Techniques are provided for tuning a two-spindle positive displacement pump that have a signal processor to receive signaling that contains information about actual pump performance data for actual nominal conditions captured during a commissioning function related to the operation of the double-spindle positive displacement pump and determining corrected data on the pump's performance to operate the positive displacement rotary pump by compensating the pump's performance data used to put the positive displacement pump into operation. double spindle based on actual pump performance data for actual nominal conditions captured during commissioning function. The corrected pump performance data includes corrected pump performance data that have a corrected published power and nominal slip factor and the actual pump performance data contains information about the actual related power, specific gravity and viscosity. with the operation of the positive displacement pump with double spindle and received from a pump controller, which includes a variable frequency unit.
