Abstract
A component, such as an electric motor, for use in a subterranean environment. The component comprises an attached recording system to record the cumulative use time of the component. The recording system typically includes a timing circuit or other circuit to output data related to use of the component. This data is recorded by a recording device to maintain a cumulative total.
Claims15
A method for tracking service time of an electric motor utilized in a subterranean environment, comprising:
- measuring the time of use of a motor via a recording device located proximate an electric motor disposed in a subterranean environment;
- collecting data from the recording device;
- transmitting data accumulated by the recording device;
- and
- servicing the motor based on data recorded by the recording device.
A method for reporting, evaluating and servicing an electric motor in a submersible pumping system, comprising:
- measuring the service life for an electric motor disposed in a submersible pumping system via a recording device located within the electric motor;
- transmitting data collected by the recording device through a transmitter to a control unit located in a position different from the electric motor;
- evaluating data transmitted to the control unit;
- and
- determining a service time for the electric motor based on data transmitted to the control unit.
An electric motor system for use in a subterranean environment, comprising:
- a housing;
- a stator disposed within the housing, the stator having a center opening;
- a rotor disposed within the opening;
- and
- a recording device coupled to a cyclic event monitor, the recording device and the cyclic event monitor being disposed within the housing, wherein the recording device maintains a log of cumulative service time.
A control system for usage in determining service life of an electric submersible pumping system component, comprising:
- an electric submersible pumping system component having an external housing;
- and
- a recording system disposed within the external housing to track and record total time of use, wherein the recording device comprises a mechanical counter.
