Daily maintenance: screw pump hydraulic anti-reverse technology

Screw pump hydraulic anti-reflection technology is to prevent the downtime of the traditional screw pump or the card pump will reverse the magnetic pole, causing technical problems with stem cells and bending strength left and ground damage equipment.
When the progressing cavity pump rod phenomenon is often reversed after a maintenance shutdown, the internal stored potential energy of the rod twist and the oil jacket pressure differential cause a magnetic pole to reverse. The sucker rod suddenly releases torque, the string of the rod stores elastic potential energy and the pressure difference affected by the oil setting, which can produce a large instantaneous torque, which is easy to cause the force to bend or cut off in the process of high-speed rotation, and the pulley is broken at high speed and flies out, which damages personnel and equipment.
The screw pump hydraulic anti-reflection technology realizes the release of torque through the hydraulic anti-reflection unit of the thread pump. The thread pump hydraulic anti-reverse screw pump unit can extend out through the hydraulic brake caliper piston when the spindle is reversed after shutdown and maintenance, promoting the friction plate to clamp the brake disc, so that the system pressure drops sharply. The brake caliper loses pressure, the spindle slows down the reverse direction, the gear pump continues to work, the brake caliper again occurs pressure to clamp the brake disc, intermittently card-loosen tight-card-loosen tight, until the spindle reverse torque emission is zero, eliminating potential safety hazards.
The screw pump hydraulic anti-reflection unit can realize the internal setting of ChanXiangDing pressure unloading mechanism, the braking torque and braking are stable and reliable, and the torque of heat dissipation can be automatically released, without the need for artificial discharge torque. This unit is a stand-alone device that can be converted to the original drive device, simple to operate, reformed, and low cost.
