Abstract
The utility model relates to a motor protector in the structure of an oil-submerged electric pump Centrilift, and particularly relates to a duplex joint for an oil-submerged electric pump motor protector. The upper end face of a duplex joint connection body is provided with a screw; the lower end of the duplex joint connection body is provided with an outer screw; a double-stage check valve is screwed to the duplex joint connection body through an eccentric orifice screw thread at the bottom of the duplex joint connection body; a screwed plug is screwed to a communicating hole vertically communicating with an inner hole axis of the duplex joint connection body at the side surface of the duplex joint connection body; a straightening bearing is pressed to the inner hole of the duplex joint connection body; and an oiling nozzle is screwed tight through a screwed hole which forms an included angle of 55 degrees with the inner hole axis of the duplex joint connection body horizontally. By using the duplex joint for the oil-submerged electric pump motor protector, two-stage serial connection of the motor protector of the Centrilift structure is realized, a double amount of a motor lubricating oil can be supplied to an oil-submerged motor, the reliability of preventing a well liquid from entering the motor is substantially improved, and the provided duplex joint also has the characteristics of unchanged bearing axial force and transmission power of the protector.
Description
Technical field:
The utility model relates to a kind of motor protecter of submersible electric pump Centrilift structure, particularly a kind of submersible electric pump motor protecter duplex joint.
Background technology:
Submersible electric pump motor protecter is the important component part of electric pump unit, plays transferring power, carrying electric pump unit axial compressive force, for motor provides lubricating oil, prevention well liquid, enters the effects such as motor.What the motor protecter of Centrilift structure was used at present is a joint protector, and for the oil well of hole condition more complicated, the number of times of motor start and stop is more, so the possibility that protector lost efficacy is just larger, and then can cause whole unit to burn.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of submersible electric pump motor protecter duplex joint; this device has been realized the motor protecter two joint series connection of Centrilift structure; can provide double dynamo oil for submersible electric machine with oil; the reliability that stops well liquid to enter motor improves, and does not change the carrying axial force of protector and the characteristic of transferring power.What overcome that the motor protecter of existing Centrilift structure uses is a joint protector, the larger deficiency of possibility that protector lost efficacy.
Technical solution adopted in the utility model is: a kind of submersible electric pump motor protecter duplex joint, comprises duplex connector interfaces; Duplex connector interfaces is designed with screw on upper surface, duplex connector interfaces lower end is designed with external screw thread, two-stage ball-and-seat is screwed on duplex connector interfaces by the eccentric orfice screw thread of duplex connector interfaces bottom, duplex connector interfaces side plug is screwed into duplex connector interfaces on the intercommunicating pore of axially bored line vertical connection, alignment bearing is pressed into duplex connector interfaces endoporus, oiling is chewed by becoming the screwed hole of 55 degree angles to tighten with duplex connector interfaces endoporus axis horizontal, on duplex connector interfaces sidewall, axially has intercommunicating pore.
The beneficial effects of the utility model are: the utility model has been realized the motor protecter two joint series connection of Centrilift structure; can provide double dynamo oil for submersible electric machine with oil; the reliability that stops well liquid to enter motor improves, and does not change the carrying axial force of protector and the characteristic of transferring power.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of intercommunicating pore.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of submersible electric pump motor protecter duplex joint, comprises duplex connector interfaces 1; Duplex connector interfaces is designed with screw on 1 upper surface; duplex connector interfaces 1 lower end is designed with external screw thread; two-stage ball-and-seat 5 is screwed on duplex connector interfaces 1 by the eccentric orfice screw thread of duplex connector interfaces 1 bottom, prevents that well liquid from entering into lower protector.In duplex connector interfaces 1 side, plug 2 is screwed on the intercommunicating pore with the interior axially bored line vertical connection of duplex connector interfaces 1, being in the process of lower protector oiling, can opens plug 2, after oiling finishes, tighten plug 2.Alignment bearing 4 is pressed into duplex connector interfaces 1 endoporus, solves the run-out error of protector axle head.Oiling chews 3 by becoming the screwed hole of 55 degree angles to tighten with duplex connector interfaces 1 endoporus axis horizontal, is embodied as the oiling of upper joint protector.On duplex connector interfaces 1 sidewall, axially have intercommunicating pore 6, guarantee that upper and lower protector is communicated with.During use, duplex connector interfaces 1 external screw thread one end is screwed on the housing of lower protector, dock with the flange face of upper joint protector by screw upper end.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection range of the present utility model.
