| 摘要 | A control system (100) is configured to actuate a tubular handling tool (60). The system includes a fluid source (10) and a tubular handling tool having a plurality of piston cylinders (61) and a plurality of slips (66) configured to engage a tubular string. The system also includes a volume synchronizer (20) having a plurality of first chambers (21A, 22A, 23A) in fluid communication with the fluid source, a plurality of second chambers (21B, 22B, 23B) 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. | ||||||
