NKY-Y732 torque control recorder of hydraulic power tongs (abbr. TPC) is a kind of torque signal treatment, control and record system. It may measure, show, record and control any torque in the period of tube makeup to ensure the optimal screw torque and save any chart data of every joint in tightening process in disc for query in the future.
TCP system is in corollary use with XQ114/6YI Tubing Tongs. It may realize automatic controls on screw torque of tube joints and ensure controlling screw torque of tube joint in a range recommended in API Standard. It may avoid thread gluing and tongs teeth damaging any tube
because of over torque when tightening any tube joint so as to meet strict standards and requirements for tube down-hole.
1. Main System Composition
TPC is composed mainly of portable computer, power converter, torque display, upload control assembly, electromagnetic unloading valve and communication cable.
2. Basic Operation Principle
Torque detection and control: When the hydraulic power tongs running at the end of hydraulic power tongs tailstock or ropes of high-precision torque sensor, direct measurement of the main clamp on the button when the rotary torque generated by the value of the torque generated signals and the number of weeks pulse signal sent to the lower machine torque acquisition card, upon the AD converted digital data uploads from the operator control lever assembly through the communication cable cross transmitted to the power converter, the data conversion Convert data to the post-PC portable computer, the PC for computing and processing. Portable computer parameter settings, the process shown program control, and related parameters recorded. Generate real-time torque current value, when to display torque, the host computer started drawing, when the torque control to set torque value, the output control signal PC to the next bit plane, the control electromagnetic relief valve to open, overflow condition in the hydraulic system, then the main clamp will automatically stop rotating, the effect of play control.
3. Functions and Characteristics
3.1 Elastic body torque torque sensor, the sensor is a strain sensor, zero stability, high precision and interference ability, high reliability, by the power supply for a variety of occasions, bad weather and all kinds of corrosive environment medium. No need to add hydraulic oil.
3.2 With sampling rate, 12-bit high-precision analog A / D converter module for input and output.
3.3 Coordinate with electromagnetic unloading valves in hydraulic power station so as to realize any automatic control of makeup torque.
3.4 Set up makeup process parameters as well as tube body and coupling parameters according to the requirement of operating process.
3.5 It is suitable for any makeup of circular buckle thread.
3.6 It is suitable for VAM TOP gas seal buckle closure, BGT1 gas seal buckle closure as well as special closure thread makeup so as to detect and record any tightening torque, shoulder torque, shoulder turn number and shoulder torque ratio.
3.7 Display, control and record any makeup process data as well as record them at disc for query in the future.
3.8 Carry out multiple page printing. An A4 paper may be printed with one or eight figures.
3.9 Software, hardware design and reliable, functional, simple, reliable, easy maintenance, suitable
for harsh working environment well site.
