Pump off has traditionally been the term used to describe the condition when a pump must shut off to protect itself after the surplus liquid is removed from the annulus or casing. This has the effect of generating an unbalanced condition where there is a sudden change in the normal torque required of the motor.

Safety Features in the IronHorse VFD for Beam Pumps

Posted on June 01, 2015 by SPOC Automation

Safety Features in the IronHorse Variable Frequency Drive for Beam Pumps

The IronHorse drive provides several safety features.

  • Termination point for local field safety shut downs. Most pumping unit installations include local field safety shut downs. These can include: environmental protection (‘enviro-pot’), vibration switches, flow line switches and tank battery shut downs. The IronHorse (IH) provides a termination point for the local field safety shut downs as a standard feature. If the end user has several safety kills they prefer to use at one time, all field safeties can be ran in series and provide VFD shut down.

  • Control (local or remote) lockout. The IH provides an HOA switch (Hand-Off-Auto). This feature lets the pumper prevent a switch from local to remote control (or vice versa), which can very important while working on a well. For example, if the pumper is on site doing a maintenance repair nobody should be able to startup the drive remotely. This is an important safety feature, for both the pumper and the pumping unit itself. It is also important that the pumper be able to switch to local while on site when the VFD unit is not near the pump itself. That way the pumper can adjust settings while directly observing the equipment, and it is important that nobody at this point be able to make changes directly to the drive.
