VOLUME SYNCHRONIZER FOR TUBULAR HANDLING TOOLS

摘要

A control system is configured to actuate a tubular handling tool. The system includes a fluid source and a tubular handling tool having a plurality of piston cylinders and a plurality of slips configured to engage a tubular string. The system also includes a volume synchronizer having a plurality of first chambers in fluid communication with the fluid source, a plurality of second chambers in fluid communication with the piston cylinders, a piston separating each of the first and second chambers, and a rod member connected to each piston. Pressurized fluid supplied to the first chambers simultaneously moves each of the pistons to simultaneously force pressurized fluid out of the second chambers and into the piston cylinders to actuate the slips into engagement with the tubular string.

1. A control system, comprising:
a fluid source; a tubular handling tool having a plurality of piston cylinders and a plurality of slips configured to engage a tubular string; and a volume synchronizer comprising:
a plurality of first chambers in fluid communication with the fluid source;a plurality of second chambers in fluid communication with the piston cylinders;a piston separating each of the first and second chambers; anda rod member connected to each piston; wherein pressurized fluid supplied to the first chambers simultaneously moves each of the pistons, thereby forcing pressurized fluid out of the second chambers and simultaneously into the piston cylinders of the tubular handling tool, thereby actuating the slips into engagement with the tubular string.
