Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
1- motor cabinets in figure, 2- oil fuel tubes, 3- lower bearing inner caps, 4- field frame assemblies, 5- outlet boxes, 6- upper end covers, 7- connection
Axle device, the small axles of 8-, 9- mechanical sealing bases, 10- upper bearing (metal) enclosing covers, 11- upper bearing (metal) inner caps, 12- rotors.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of oil well directly-driven screw pump surface drive, including motor cabinet 1, field frame assembly 4, rotor
12, the left end of rotor 12 is supported on motor cabinet 1 by lower bearing, is fixed on the right side of lower bearing by lower bearing inner cap 3, and under
Internal bearing cover 3 is fixed on motor cabinet 1, and oil fuel tube 2 is connected with lower bearing inner cap 3.The right-hand member of rotor 12 passes through upper axle
Hold and be supported on upper end cover 6, the upper bearing (metal) passes on left upper bearing (metal) inner cap 11 and fixed, upper bearing (metal) enclosing cover is passed through on the right side of upper bearing (metal)
10 are fixed, and upper bearing (metal) inner cap 11 is both connected on upper end cover 6 with upper bearing (metal) enclosing cover 10.The field frame assembly 4 is placed in rotor 12
Outside, and the outside of field frame assembly 4 is provided with outer barrel, outer barrel left end is connected on motor cabinet 1, and right-hand member is connected with upper end cover 6, and outer barrel
It is provided with outlet box 5.The right-hand member of rotor 12 is supported inside the upper end cover 6 by upper bearing (metal), the right-hand member of rotor 12 is connected with
Shaft coupling 7, by the drive screw pump of shaft coupling 7, the inside of rotor 12 is provided with small axle 8, and machine is provided between the small right-hand member of axle 8 and rotor 12
Tool seal receptacle 9, the small left end of axle 8 is connected with main shaft.
The device is directly driven using permanent magnet synchronous ac motor, efficiency high, and torque is big, and power savings are notable.Due to saving
Machine driven system has been gone, thus it is simple in construction, and easy to maintenance, maintenance cost is few, easy for installation, and floor space is small.The device
Allow damping to generate electricity to invert, and with Torque Control function, as a result of Torque Control, make card well torque controllable, Dang Kajing
When torque is more than 1.5-2.5 times of work torque, within 1-2 seconds time, power supply is automatically cut off when not dropping to normal work torque,
Surface drive is stopped.Now rotating forward energy storage of polished rod during card well, drive motor is rotated when reversion release card turns
Elastic kinetic energy, motor now will become generator, and damping is produced by braking resistor, move the elasticity that polish rod clamp memory dump is deposited
It can discharge, completely eliminate the potential safety hazard that polished rod adjusts rotary flying apparatus.
