进口反转螺杆泵Product Description:

The direct drive device includes an AC direct drive motor, a polished rod, etc. the center of the AC direct drive motor is provided with a hollow motor rotor, the polished rod is inserted into the motor rotor, the outer side of the upper end of the motor rotor is fixedly connected with a polished rod holder, and the outer side of the AC direct drive motor is provided with an anti rotation mechanism, including a brake disc, a hydraulic caliper and a hydraulic control mechanism. The brake disc is fixedly arranged on the motor rotor and can rotate with the motor rotor, The edge of the brake disc is inserted into the jaw of the hydraulic caliper. The hydraulic control mechanism is connected with the hydraulic caliper through the hydraulic oil circuit and controls the opening and closing of the jaw. The device adopts the automatic hydraulic braking mode, which does not need human intervention and approach. The braking torque is large, the fluid drop of the pipe string and the friction torque of the rod string are safe and stable, and can be released slowly. The torque release system is more stable, greatly reducing the occurrence of safety accidents.

进口反转螺杆泵characteristic:

进口反转螺杆泵Two way gear pump oil storage box control module, belt pulley and belt. The belt pulley is fixedly connected to the motor rotor and rotates with the motor rotor. Both ends of the belt are respectively connected to the belt pulley and the rotating shaft of the two-way gear pump. The belt pulley drives the rotating shaft of the two-way gear pump to rotate through the belt. Between the oil storage box and the two-way gear pump, between the two-way gear pump and the control module, between the control module and the hydraulic caliper An oil circuit is arranged between the control module and the oil storage box, and the bidirectional gear pump can pump the hydraulic oil in the oil storage box to the hydraulic caliper through the control module; The upper end of the AC direct drive motor is provided with a shield, and the anti reverse mechanism is arranged in the shield; A sealing packing is arranged between the polished rod and the motor rotor, a packing pressing sleeve is arranged on the sealing packing, and the sealing packing and packing pressing sleeve seal the gap between the polished rod and the motor rotor; A smooth rod stabilizing ring and a thrust ball bearing are arranged in the middle of the lower end of the AC direct drive motor, the smooth rod stabilizing ring is sleeved on the smooth rod, and the thrust ball bearing is sleeved on the motor rotor; The bottom of the AC direct drive motor is fixedly connected with a connecting flange, and the AC direct drive motor is connected with the oil well cross through the connecting flange; AC direct drive motor is flameproof.
