Solar-Powered Injection Pumps
●During the winter glycol is often injected into natural gas pipelines to keep the natural gas flowing. Originally, the natural gas in the pipeline was used to drive pneumatic pumps for injecting the glycol. However, the industry phased out this practice due to increasingly stringent EPA regulations. Pump manufacturers turned to solar powered electric pumps (click here for more about Bodine low voltage products). While solar power is in abundant supply on sunny days, it is scarce on cloudy days. The injection pumps needed to operate reliably despite this fluctuating power source.
●Bodine worked with a pump manufacturer to improve the system efficiency. To eliminate some sources of power loss we started with a brushless DC motor. We optimized its 12 Volt winding so that the maximum efficiency point coincided with the typical load point of the application. We then provided a parallel shaft gearhead with spur and helical gearing, with a low number of stages to improve efficiency.
●Our customer observed that the batteries drained fastest when the outdoor temperature was extremely low. Bodine engineers provided a gearhead that utilized low-viscosity synthetic lubricant. This lubricant was specifically designed for use in environments with a wide temperature range. The new gearmotor used less power, which enabled the injection pumps to provide many more hours of uninterrupted service.
