PS Deflected Welltype Pneumatic Spider

PS SERIES pneumatic lock tile is a type of pneumatic operational tool to screw down the drill rod and clamp the sleeve in the petroleum and natural gas drilling work. It is applicable for the turntable for various drilling machine. The pneumatic lock tile is characterized by high degree of mechanical work, convenient operation, large lifting force, wide application range, safety and reliability. It is capable of reducing the labor intensity and improving the operation by a large scale. In the operation of screwing down the drill rod, automatic silt scraping can be conducted.

The working principle and features of PS Deflected Welltype Pneumatic Spider

PS Series pneumatic lock tile is mounted in the turntable as a substitute for the core bit of the turntable. In operation, when the control valve is turned to the side of falling, the lock tile body travels down along the principle cone and pushes the tubular column to furl centripetally, thereby clamping the tubular column; when the control valve is turned to the side of lifting, the lock tile body is loosened and travels up to the upper place, so as to make room for the tubular column and the joint loop to pass.

The pneumatic system is provided with a pressure regulator-filter, which is able to filter the compressed air and reduce the air pressure, so as to satisfy the demands of the pneumatic lock tile system. The compressed air filtered and adjusted is supplied into the cylinder. The manipulation and control handle is used to control the cylinder that drives the equilibrium beam up and down to push the lock tile to uplift and lower.
