Now reverse, the rod and column torsion
Screw pump hydraulic anti-reverse technology is to prevent the traditional screw pump downtime or the pump will reverse in the magnetic pole, causing stem cells and bending strength left, ground damaged equipment technical problems.
When the screw pump rod phenomenon is often reversed after shutdown and maintenance, the internal storage potential energy of the rod and column torsion and the difference between the oil sleeve pressure will lead to a magnetic pole reversal. The pumping rod suddenly releases the torque, the character string of the rod stores the elastic potential energy and the pressure difference affected by the oil setting, which can produce a huge instantaneous torque, easy to cause the force to bend or cut off in the process of high-speed rotation, the pulley broken out at high speed, the damage to personnel and equipment.
The screw pump hydraulic reaction technology is released through the thread pump hydraulic reaction unit. Thread pump hydraulic anti-reverse screw pump unit can be when the shutdown maintenance spindle reversal, through the hydraulic brake caliper piston out, promote the friction plate clamp the brake disc, so that the system pressure is sharply reduced. The brake calipers lose pressure, the spindle slows down the reverse, the gear pump continues to work, the brake calipers have pressure to clamp the brake disc again, and the card-loosen tight-card-loosen tighten intermittently until the spindle reversal torque emission is zero, eliminate safety risks.
The hydraulic anti-restraint unit of the screw pump can realize the internal setting of the ChanXiangDing pressure discharge mechanism, the braking torque and braking are stable and reliable, and the heat dissipation torque can be released automatically, without manual discharge torque. This device is independent equipment, can be converted in the original drive equipment, easy to operate, reform, low cost.
