Description
Technical field
The present invention relates to oil extraction in oil field technical field, belong to for improving screw pump safety, reducing production cost
A kind of no polished rod hydraulic braking direct driving device.
Background technique
In field of oil field oil extraction, screw pump as a kind of lifting equipment viscous crude, containing obtained in sand, high-gas-contained well compared with
Good application and adaptability, screw pump ground driving device is mainly using general drive form and straight drive form, two kinds of driving sides at present
Formula has some problems in application process: 1) general driving device motor and retarder are connected with belt, screw pump operation process
In, once holddown phenomenon occurs, huge torque can start to discharge moment, and surface drive retarder can run at high speed, and cause
Belt flying wheel causes huge security risk to ground staff.2) magneto direct driving device is when screw pump inverts, electricity
Machine, which is easy power generation, causes frequency conversion tank to burn out.3) magneto manufacturing cost is higher.4) magneto direct driving device is transported in long-time
Turn or when motor temperature is higher, a possibility that there are demagnetizations reduces motor output torque, influences screw pump jacking capacity.
Summary of the invention
The object of the present invention is to provide for improving screw pump safety, reduces safety accident probability of happening, reduces
Production cost realizes a kind of no polished rod hydraulic braking direct driving device efficiently lifted.
The technical scheme adopted by the invention is that:
A kind of no polished rod hydraulic braking direct driving device, it is by driving motor, motor shaft, transmission shaft, key, brake, support, bearing
Case, bolt, pedestal composition；Wherein driving motor is bolted with support, and inside driving motor, motor shaft exists motor shaft
Driving motor motor internal axis is connected by key with transmission shaft, and brake upper end cover is mounted on inside support, fixed, braking
Device lower cover is mounted on inside support and fixes with transmission shaft, rotates with transmission shaft, support is bolted with bearing housing, bearing
Case is bolted with pedestal.Driving motor is rotor-side variable frequency motor；Brake upper end cover and brake lower cover use liquid
Power brake.
The beneficial effects of the present invention are:
1), when reversal development occurs for screw pump, the hydraulic oil above and below hydraulic brake in end cap forms resistance under blade effect
Stream, reduces the rotation speed of polished rod, meanwhile, rotor-side variable frequency motor is acted on by self-field, inhibits polished rod speed reversal, over the ground
Face operator, driving device, subsurface equipment rise
To protective effect, safety accident probability of happening is reduced.
2), when reversal development occurs for screw pump, rotor-side variable frequency motor self generating enters power grid, right
Frequency-variable controller plays a protective role.Rotor-side variable frequency motor is in long time running, it is not easy to there is demagnetization phenomenon,
Can the long-time slow-speed of revolution, export high torque.Energy consumption reduces by 5 percentage points compared with Conventional permanent magnet motor direct-drive device, at
10 percentage points of this reduction.
3), motor shaft is hollow structure, and polished rod is mounted on inside motor, is not exposed to outside motor, increases operational security
Property.
Detailed description of the invention: Fig. 1 is the structural diagram of the present invention；
In figure: driving motor 1, motor shaft 2, transmission shaft 3, key 4, brake upper end cover 5, brake upper end cover 6, support 7, bearing
Case 8, bolt 9, pedestal 10.
Specific embodiment: the present invention will be further explained below with reference to the attached drawings: the present invention is by driving motor 1, motor
Axis 2, transmission shaft 3, key 4, brake upper end cover 5, brake lower cover 6, support 7, bearing housing 8, bolt 9, pedestal 10 form；Its
Middle driving motor 1 is connect with support 7 by bolt 9, and for motor shaft 2 inside driving motor 1, motor shaft 2 and transmission shaft 3 pass through key
4 connections, brake upper end cover 5 is mounted on inside support 7, fixed, and brake lower cover 6 is mounted on 7 inside of support and passes
Moving axis 3 is fixed, rotates with transmission shaft 3, and support 7 is connect with bearing housing 8 by bolt 9, and bearing housing 8 and pedestal 10 pass through bolt 9
Connection.
Driving motor 1 is rotor-side variable frequency motor；Brake 5 uses hydraulic brake.
In application process, motor shaft 2 is connect with transmission shaft 3 by key 4 present invention, and underground sucker rod and transmission shaft 3 connect
It connects, when screw pump operating, motor shaft 2 drives 3 synchronous rotary of transmission shaft, and brake upper end cover 5 is fixed, brake lower cover 6
With 3 synchronous rotary of transmission shaft, when screw pump inverts, lubricating oil in brake end cap 5 and brake on the brake
Lower cover 6 forms choked flow under acting on, brake force is generated, while screw pump rotor variable-frequency motor is acted on by self-field, to electricity
Arbor 2 generates magnetic brake power, reduces screw pump velocity of rotation, improves production security.Screw pump rotor variable-frequency motor can be
Low-speed big output power is kept in the case of long time running, realizes efficiently lifting.
