Dynamic Transmission Output Control Revolutionizes Well Service Automated Speed Control for Low Flow Applications

Caterpillar Oil & Gas is pleased to announce the Cat® Dynamic Transmission Output, allowing for manual shift Automated Speed Control (ASC) of the Cat CX31-P600 Well Service Transmission for well service pumping applications, cementing and mobile work over rigs. The new Dynamic Transmission Output Control is an integrated system; designed with knowledge of the engine and transmission operating characteristics.

“The primary benefit of the Cat ASC is the ability to achieve consistent low flow during critical cementing applications,” said Rodney Harms, well service manager for Caterpillar Oil & Gas. “The system controls output speed via the torque converter lock-up clutch to achieve precise flow control. This ability to automatically control the output speed to achieve very low speeds mimics a deep first gear ratio, giving well service operators a new tool to perform low flow operations.”

The feature is targeted to cementing applications which can require 0.25 BPM flow rate. Cementing applications require precise flow control when performing squeeze jobs, which are completed with very low flow rates. The Cat DTOC system provides a safe “soft link” for control of the torque converter lock up which translates to precise flow control.

“The system works through simplified operation allowing more precise flow control and reduced bumping in and out of gear,” states Harms. “It also allows for more reliable operation by limiting heat rejection and increased lube flow for improved durability.”

The Cat engine and transmission monitoring systems continuously monitor and report engine performance, enabling operators to identify inefficiencies, maintenance issues or engine warnings.  The system monitors transmission oil temperatures to ensure safe and reliable completion of jobs without exceeding allowable values maintaining system life and integrity.

The Cat DTOC is available now through the worldwide Caterpillar dealer network. Low operating cost and proven reliability have made Cat® engines, transmissions and pumps the preferred choice in the oilfield.
