Design features of spinner

The kelly spinner is a special device that uses hydraulic pressure or air pressure as power during the drilling process to drive the kelly rod to rotate, and is used in conjunction with the mouse hole caliper to automatically complete a single connection. It is characterized by safety, high efficiency, and reduced labor intensity of workers. In addition to fast picking up a single root, it can also be used for fishing operations, finding direction or drilling tools that require slow rotation, and for drilling large and small holes.

XFK-77Y (Y) type kelly spinner is developed based on advanced American prototypes and combined with domestic conditions. This spinner has the characteristics of compact structure, convenient use, safety and reliability.

The XFK-77Y (Q) type kelly spinner is mainly composed of hydraulic or pneumatic motor, housing, drive shaft, reduction gear, main gear ring, ratchet teeth, bearing, seal, brake ring and brake spring, etc. Partial composition.
