Abstract
The utility model relates to a rotatable eccentric test screw pump drive device. The problems are mainly solved that in the prior rotatable eccentric test screw pump drive device, the transmission torque is small, the power consumption is large, the lowering down of the teat device is not smooth, etc. The rotatable eccentric test screw pump drive device is characterized in that the upper portion of a rotatable test four-way communicating body (5) is fixedly provided with a motor support (3), and the top of the motor support (3) is fixedly provided with a direct-driven motor (2). The drive device is characterized in that the transmission torque is large, the current is small, the electrical loss is little, the lowering down of the teat device is smooth, etc.
Description
Technical field
The utility model relates to the used device of oil well mouth, a kind of specifically rotatable eccentric testing driving unit on screw pump.
Background technique
The rotatable eccentric testing driving unit on screw pump of existing oil well mouth adopts motor to combine transmission with umbrella gear mostly, and for side direction drives, have following problem: 1, driving torque is little, electric current is big, power loss is big; 2, it is not smooth to be subjected to the spatial constraints test instrument to transfer process, thereby causes the test time long; 3, to transfer angle big for test instrument, must increase the electric machine support height, has potential safety hazard.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing rotatable eccentric testing driving unit on screw pump, the utility model provides a kind of rotatable eccentric testing driving unit on screw pump, and this drive unit has that driving torque is big, electric current is little, electrical loss is little, test instrument is transferred characteristics smoothly.
The technical solution of the utility model is: a kind of rotatable eccentric testing driving unit on screw pump, comprise the rotary test four-way body that is fixed on well head big four top, and rotary test four-way body top is fixed with electric machine support, and the electric machine support roof anchorage has direct driving motor.
The utlity model has following beneficial effect: owing to take such scheme, change the side direction drive motor into direct driving motor, saved horizontal space, the angle that test instrument is transferred diminishes, instrument is transferred more smooth and easy, and reduced the height of electric machine support, also saved longitudinal space, Security is better; The direct driving motor driving torque is big simultaneously, electric current is little, electrical loss is little, and is more energy-conservation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
1-seal arrangement among the figure, 2-direct driving motor, 3-electric machine support, 4-test strobe, 5-rotary test four-way body.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of rotatable eccentric testing driving unit on screw pump, comprise the rotary test four-way body 5 that is fixed on well head big four top, be connected with test strobe 4 on the eccentric testing passage of rotary test four-way body 5, open test strobe 4 when carrying out eccentric testing and get final product.Rotary test four-way body 5 tops are fixed with electric machine support 3, and electric machine support 3 roof anchorage have direct driving motor 2, and the top of direct driving motor 2 is by seal arrangement 1 sealing.This rotatable eccentric testing driving unit on screw pump is compared with existing drive unit, change vertically the side direction driving of motor into directly driving, saved the space, it is more smooth and easy that test instrument is transferred, and since test transfer angle become with, thereby reduced the height of electric machine support, improved Security; The direct driving motor driving torque is big simultaneously, electric current is little, electrical loss is little, and is more energy-conservation.
Claims (1)
1. rotatable eccentric testing driving unit on screw pump, comprise the rotary test four-way body (5) that is fixed on well head big four top, it is characterized in that: rotary test four-way body (5) top is fixed with electric machine support (3), and electric machine support (3) roof anchorage has direct driving motor (2).
