Earth drilling rig having electronically controlled air compressor
InactiveUS20070246262A1Reduce generationImprove drilling qualityDrilling rodsConstructionsCritical levelElectronic controller
In an earth drilling rig in which an air compressor and one or more hydraulic pumps are driven by the same engine, the intake throttle of the compressor is controlled by an electronic controller having a proportional integral derivative control. The controller minimizes unloading of the compressor, allowing the engine to operate more efficiently, the hydraulic system to provide more consistent power to drilling functions and the volume and pressure of compressed air to be optimized for the drilling conditions encountered. The electronic controller also operates a blowdown valve at the discharge side of an air receiver, and effects various overrides of the control system, for example when air discharge temperature approaches a critical level, or when an overpressure condition is detected.
