Abstract

The utility model discloses a sealed drive device in particular fit for motor power output in a high pressure water injection well of an oil field. A support drum is provided on the motor. A flexible sealing sleeve is sleeved on the support drum and the connecting drum. The oil chamber outer pipe is sleeved on the flexible sealing sleeve and is connected with the connecting drum thread. A motor connection control chamber is also positioned in the connection drum. A nut connected with the inner thread of the connection drum travels presses the conical surface port of the flexible sealing sleeve onto the surface of the support drum by the motor connection control chamber. A through line hole is arranged on the motor connection control chamber to assemble a sealing plug. The electricity source wire of the motor travels through the sealing plug and then is led into the motor connection control chamber. A balance hole that is communicated with the inner chamber is arranged on external pipe of the oil chamber. The flexible sealing sleeve is filled with isolating oil that can marinate the motor.

Description

Sealed gearing device

Technical field:

The utility model relates to a kind of sealed gearing device, particularly relates to a kind of sealed gearing device that is used for high oil field water injection well output motor power, belongs to the electric-motor-driving technical field.

Background technique:

At present, in the prior art, generally all directly adopt electric-motor-driving or driving to need the device of power, because in the process of transferring power, driven object is easy to make the motor axially loaded under the effect of ambient pressure, thereby influence the normal operation of motor, the motor of in the high oil field water injection well, working particularly, because motor and the power that is connected on the motor are exported the axial action that Coupling Shaft usually is in the well high pressure water, make motor will bear very big axial force in the running, so motor is easy to be worn and damage and intake and damage.

Summary of the invention:

The purpose of this utility model is: provide a kind of and can make that motor operates steadily, water-proof performance is good, reduce extraneous high pressure water to motor axial force, motor long sealed gearing device in working life, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: it comprises connecting cylinder (7) and motor (14), profile of tooth sliding ring type combination seal (8) is housed on connecting cylinder (7), Coupling Shaft (9) and nut (10), motor (14) is fixed on the mounting plate (12) by screw (5), mounting plate (12) is fixed on connecting cylinder (7) by screw (11), and the semicircle axle of motor (14) rotating shaft front end is inserted in the semicircle orifice of Coupling Shaft (9) and is connected with Coupling Shaft (9), on motor (14), be with a supporting drum (16), on the barrel of supporting drum (16), be provided with small through hole, on supporting drum (16) and connecting cylinder (7), be with flexible gland (15), oil pocket outer tube (17) covers on flexible gland (15) and upward and with connecting cylinder (7) is threaded, motor wiring control storehouse (3) also is housed in connecting cylinder (7), the nut (1) that is connected with the internal thread of connecting cylinder (7) is pressed against on the end face of supporting drum (16) by the conical surface port of motor wiring control storehouse (3) with flexible gland (15), on motor wiring control storehouse (3), be provided with the threading hole that sealing plug (4) is installed, the power line of motor (14) is incorporated into after by sealing plug (4) in the motor wiring control storehouse (3), on oil pocket outer tube (17), be provided with the equalizing orifice (13) that communicates with its inner chamber, and in flexible gland (15), be full of the insulating oil that motor (14) can be soaked is arranged; Be provided with boss (2) at the two ends of supporting drum (16), and on motor wiring control storehouse (3) that contacts respectively with supporting drum (16) two ends and mounting plate (12), be provided with the hole that to insert boss (2).

Owing to adopted technique scheme, the utility model is located at motor in the flexible shell gas-tight silo that is full of insulating oil and works, and has improved the working environment of motor greatly; The utility model utilizes the scalability of flexible gland, guarantees the seal chamber internal and external pressure balance, reduces the pressure reduction at motive sealing two ends, makes motor not be subjected to responsive to axial force.Therefore the utility model compared with prior art the utlity model has and can make advantages such as the motor operation is steady more, water-proof performance is good, the machine operation life-span is long; The utility model has significantly reduced external working environment to the influence of motor, particularly significantly reduced the influence of extraneous high pressure water to the motor axial force.When using the utility model under the environment with highly pressurised liquid, when extraneous highly pressurised liquid enters in the oil pocket outer tube by the equalizing orifice (13) on the oil pocket outer tube (17), transformer oil in its flexible gland (15) is smaller volume under pressure, reach pressure balance, so promptly reduce the suffered axial force of motor, reduced the difficulty of motive sealing again.The work in oil by flexible gland and profile of tooth sliding ring type combination seal common guarantee motor also avoids occurring motor water inlet phenomenon.Motor in the utility model can be under the condition of well high pressure 60MPa proper functioning.The utility model can be used for multiple occasion and transmits motor power, uses when being specially adapted to regulate adjustable valve water nozzle on the blanking plug automatically as water injection well in oil fields injection allocation amount.
