Screw pump hydraulic anti-reversing technology

Screw pump hydraulic anti-reversing technology is to prevent the conventional screw pump wells in the shutdown or card pump column reversal, resulting in off the rod, polished rod rejection bending, ground equipment damage and other issues of technology. Screw rod pump often shut down after the pole reversal phenomenon occurs, the pole of the internal storage of torsional potential energy and the oil pressure differential may lead to pole reversal. Sudden release of the sucker rod torque, by the elastic storage rod potential energy and the impact of oil pressure differential, will have a huge instantaneous torque, easily lead to the polished rod in the high-speed rotation was thrown away or thrown off, high-speed pulley rotation Broken flying out of the staff and equipment damage. Screw pump hydraulic anti-reversing technology is screw pump hydraulic anti-reverse device to achieve the release of torque. Screw pump hydraulic anti-reversing device can stop the screw spindle after the reverse, through the hydraulic caliper piston out to promote the friction plate chuck brake disc, the system pressure rapidly reduced. After the brake caliper loses pressure, the spindle decelerates reversely and the gear pump continues to work. The brake caliper again generates a pressure chucking brake disc, so that the intermittent chuck releases and the chuck loosens until the spindle rotates reversely Torque unloaded to eliminate potential safety problems. Screw pump hydraulic anti-reverse device can be set internally to set the unilateral pressure relief mechanism, braking torque, smooth and reliable braking, heat dissipation, torque can be automatically released, without manual unloading torque. This device is a stand-alone device that can be retrofitted on an existing drive, with simple operation and low retrofit costs.
