Problems solved by technology

Variable frequency drives (VFDs) have also been used to control submersible pumps, but have limited capabilities in terms of user-friendly control and customization
Traditional drives are also usually designed for a specific type of motor and generally cannot be used to retrofit motors already installed in wells, especially two-wire single-phase motors

Abstract

A method of controlling a pump and a motor is provided. Embodiments of the invention provide a variable frequency drive system and a method of controlling a pump driven by a motor with the pump being in fluid communication with a fluid system. The drive system and the method can provide one or more of the following: a sleep mode, pipe break detection, a line fill mode, an automatic start mode, dry run protection, an electromagnetic interference filter compatible with a ground fault circuit interrupter, two-wire and three-wire and three-phase motor compatibility, a simple start-up process, automatic password protection, a pump out mode, digital input / output terminals, and removable input and output power terminal blocks.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201010242045.1, the application date is June 9, 2010, and the invention title is "Method for Controlling Pump and Motor". Background technique [0002] The submersible pump is connected to a surface driver system that controls the operation of the pump. Some traditional pump controllers include only a starting capacitor and a relay to turn the pump on and off based on system pressure. These pump controllers have limited capabilities for pump control, safety and customization. Variable frequency drives (VFDs) have also been used to control submersible pumps, but have limited capabilities in terms of user-friendly control and customization. Traditional drives are also usually designed for a specific type of motor and generally cannot be used to retrofit motors already installed in wells, especially two-wire single-phase motors.
