Benefits of technology

[0008]This patent covers a way to verify the rotation of a three phase electric motor while coupled to a pump and used in a submerged, or non submerged application for ease of verifying the correct rotation of the pump impeller so as to change the rotation if necessary to prevent damage to the pump or to improve the operation of the pump performance.

Problems solved by technology

With the use of a three phase electric submersible motor coupled to pump components, and while the entire assembled pump and motor are located or operating partially or totally submerged in the liquid pumped, the direction of rotation of the pump impeller is not easily determined as to the correct rotation of rotation as intended by the pump component manufacturer.

Embodiment Construction

[0010]This patent applies to the use of a sensor attached near the motor shaft of an electric motor that is driving a pump. The sensor shall by the direction of the motor shaft be able to close or open a circuit, or send a signal that would be transmitted by wires out of the submersible pump to a controller or relay that would be used to shut down the pump if the rotation is the wrong direction, or indicate the wrong direction as a light or signal so the direction of rotation of the pump may be changed to correct as defined by the pump manufacturer. The sensor mounted near the shaft could be of the magnetic type that by means of multiple contacts located on the motor shaft must be closed in a certain order to indicate the direction of rotation of the motor shaft. If the motor were to run in a reverse direction the sensors would close in an order to determine that the motor shaft is running in a reverse direction. These circuits when connected would then be used to prevent the motor ...

Abstract

This patent addresses a need to be able to tell in which direction of rotation an electric motor is turning when connected to a pump, and in particular, a submersible pump where the direction of the motor shaft is not installed where visual observance of the direction of rotation is possible. This patent covers the modification of any existing motors or pumps to include any device, circuit, or change to sense, measure, or pick up the direction of rotation of an electric pump or motor for the purpose of knowing the direction the motor or pump is turning when operating or bumped for observation.It is appreciated that there may be ways to sense, transmit, store, or measure the direction of rotation of a pump or motor other than in the embodiments described above, however this patent application is not limited to the embodiments above but cover and include the spirit and intent of the invention as defined in the claims above.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]Not applicableSTATEMENT REGARDING FEDERALLY SPONSORED RESEARCH FOR DEVELOPMENT[0002]Not applicableTHE NAMES OF THE PARTIES TO A JOINT RESEARCH AGREEMENT[0003]Not applicableINCORPORATION-BY-REFERENCE OF MATERIAL SUBMITTED ON A COMPACT DISC[0004]Not applicableBACKGROUND OF THE INVENTION[0005]A three phase electric motor may be operated in either direction of rotation. When initially powered for operation, it is not always known in which direction of rotation the electric motor will initially turn. After the initial rotation of an electric motor is determined from observation the direction of rotation may be changed by swapping any two of the incoming three power supply phases. This then reverses the rotation of direction of a three phase electric motor.[0006]When an electric motor is used to operate a pump, the direction of rotation of the pump and motor must be verified as correct for operation as recommended by the pump manufacturer.
