Description
Technical field
The utility model belongs to oil pumping in oil fields spiral pump motor field, is specifically related to a kind of multipole low speed high torque oil pumping helicoidal pump motor.
Background technology
Oil pumping is widely used a kind of motor on oil field with helicoidal pump motor, as illustrated in fig. 1 and 2, this motor in the ordinary course of things power for being 12/8 utmost point, corresponding synchronous speed is respectively 500r/min and 750r/min, corresponding torque is respectively 420N.m and 280N.m, motor rotary shaft is solid shafting, need support the use and just can reach instructions for use with reductor.This motor in use there will be following problem:
(1) common motor rotating speed is higher, and need join reductor could use, and package unit is heavier, loaded down with trivial details like this, and cost is very high, and efficiency is very low.
(2) security presence significant problem.Due to the handling characteristics of helicoidal pump motor; this motor there will be the existence of spiral force reaction power to there will be reversion in down-hole part in the time shutting down; the higher speed reversal of rotating speed is higher; repeatedly just can stop several times, because former 12/8 pole motor is because rotating speed is higher, when shutdown, converse rotating force is larger; need artificial brake; to repeatedly just can stop several times, in the time that Daqing oil field uses, once shut down reversion, due to converse rotating force cross senior general institute carrying device throw away cause kill 3 own business therefore.
(3) motor efficiency is low.Use because this motor needs supporting reductor, process intermediate link greatly reduces with behind efficiency like this, causes motor power consumption greatly to improve, and does not meet our country's principles and policies of the energy-saving and environmental protection of promotion now.
(4) improve motor in the past and adopt reducer arrangement, connect oil pumping helicoidal pump by decelerator, under the connecting rod of oil pumping with helicoidal pump, wear drill bit or helicoidal pump, need first helicoidal pump is imported by the method for our routine underground, then installation connection reductor and motor, narrow space, installation exercise difficulty, and after installing, because assembly is too much, easily there is the problem of the aspects such as vibration, make troubles to oil field operation.
Therefore traditional oil pumping is badly in need of improving with helicoidal pump motor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of multipole low speed high torque oil pumping and uses helicoidal pump motor, consume energy low, efficiency is high, and easy for installation, durable in use.
For solving the problems of the technologies described above, the technical solution of the utility model is: invent a kind of multipole low speed high torque oil pumping helicoidal pump motor, comprise motor rotary shaft, blanking disc and encoder are installed on the motor reel of motor casing outside, stator and rotor are installed in the shell of motor, are it is characterized in that: motor is 24/16 pole switching reluctance motor; Motor rotary shaft is hollow shaft, and motor rotary shaft connects the connecting rod of oil pumping helicoidal pump.
Helicoidal pump motor is used in multipole low speed high torque oil pumping described in the utility model, it is characterized in that: the spindle nose at motor rotary shaft is installed drive sub, and motor rotary shaft connects the connecting rod of oil pumping helicoidal pump by drive sub.
Motor rotary shaft is connected with the connecting rod plug-in mounting of helicoidal pump with oil pumping, and grafting key is set on motor rotary shaft, on the connecting rod of helicoidal pump, offers inserting groove, and grafting key inserts in inserting groove.
The synchronous speed of motor is respectively 250r/min and 375r/min, and corresponding torque is respectively 840N.m and 560N.m.
Compared with prior art, the beneficial effects of the utility model are:
1, motor rotary shaft adopts hollow shaft structure, not only saves material, and is convenient to install.Motor rotary shaft can connect by drive sub the connecting rod of oil pumping helicoidal pump, or be directly plugged in together by keyway arrangements with connecting rod, easy for installation, and structure is simplified reliably, omit after reductor, avoided the problems such as the vibration that coupling assembling too much causes.
2, cost, performance improve.After improving, because electromotor series increases, rotating speed reduces, and torque corresponding in the situation that power is constant improves greatly, so just met the demand of condition of work, no longer needed reductor, motor takes up room and greatly reduces like this, total manufacturing cost also obviously reduces, and installs and also greatly simplifies.
3, security performance has obtained very large improvement.Original device is because rotating speed is higher; reaction force when shutdown is very large; motor itself has again very large inertia; while causing shutting down, to repeatedly just can stop several times; we are during with 24/16 pole switching reluctance motor, because rotating speed has reduced very greatly, add that switched reluctance motor itself has reaction force; while shutdown like this, will soon stop, security performance has obtained very large improvement.
4, energy-efficient.Former motor is asynchronous machine acceleration and deceleration devices, and loss is the loss acceleration and deceleration machine loss sum of motor.Present loss only has switched reluctance motor, switched reluctance motor itself is energy-efficient motor, adds the loss of having saved reductor, according to test, the multipole low speed high power intelligent motor that we do is energy-conservation 20～30% compared with original device, energy-saving effect highly significant.
5, the utility model is simple in structure, and dependable performance is convenient in industry apply.
