Description

Technical Field

[0001] The invention relates to the technical field of motors for workover rigs, and in particular to a low-speed, high-torque switched reluctance motor for a workover rig. Background Art

[0002] Well repair rigs are the most basic and main power source for well repair and underground operations. According to their operating structure, they are divided into two types: crawler type and tire type. At the same time, the motor used in the well repair rig is a reluctance motor with a torque switch, and the reluctance motor is a continuously running electrical transmission device. Its structure and working principle are very different from traditional AC and DC motors. It does not rely on the interaction of the magnetic field generated by the stator and rotor winding currents to generate torque, but relies on the "minimum reluctance principle" to generate torque. A reluctance motor under the existing technology can use a low-power transformer to operate briefly overloaded to drive the motor to start.

[0003] Reluctance motors can be used in well repair rigs, and the operation process of well repair rigs is characterized by a long time, so the reluctance needs to work continuously. For any machine, long-term operation will inevitably cause the temperature to rise, and the reluctance motor is no exception. Therefore, it is far from enough to rely solely on the heat dissipation capacity of the reluctance motor itself. The reluctance motor is exposed outside the well repair rig, and the ordinary wind cooling is not the best cooling effect for the reluctance motor, and the power problem required for wind cooling needs to be solved. Therefore, the most effective result is to provide liquid cooling for the motor, which can not only effectively dissipate the heat of the motor, but also recycle the coolant.

Further, when the coolant in one liquid storage tank 3 enters another liquid outlet tank 3 and is cooled, the height between the two liquid outlet tanks 3 can be exchanged. Specifically, the push slider 44 is pulled by the control panel 45. At this time, the push slider 44 slides inside the external groove 42, and the second return spring 43 is deformed by accumulating force. Further, the limit block 46 leaves the adjustment frame, and the connecting frame 47 can be adjusted at this time.
