Description
Technical field
The utility model relates to oil field oil recovery machiner apparatus field, relates in particular to the special-purpose permanent magnetism transmission device in oil field.
Background technology
At present, the recoverable amount of China's oil pumper is more than 100,000, and motor installation total capacity is at 3500MW, and annual power consumption exceedes 10,000,000,000 kWh.Oil pumper is the oil field big power consumer, and power consumption accounts for 40% of oil field total electricity consumption, and the operational efficiency of oil pumper is low especially, causes the grid electricity fee cost of oil mining high, and energy waste is very serious.Be 25.96% in China's average efficiency, and external average level is 30.05%, year energy-conservation potentiality can reach tens kWh.So petroleum industry is attached great importance to saves energy.
At present, oil pumper is one of capital equipment of oil field electricity consumption, is a kind of plunger displacement pump, be the permanent torque loads of periodically pulsing to motor, and superposition has the impact of moment.Two peak values are arranged on the load curve of pumping-unit motor, be respectively " dead point " of oil pumper up-down stroke.When restarting behind the oil pumper free parking, always start from the dead point, so pumping-unit motor requires detent torque big.In order to guarantee enough big detent torque, when the apolegamy pumping-unit motor, always select the motor of big specification for use, can only be low load with strong power.Load factor was very low when pumping-unit motor normally moved, generally about 20%, load factor high only 30%.The operation of underload rate causes power factor low, and efficient is low, and waste of energy is serious.
Summary of the invention
The utility model is intended at the deficiency that exists in the background technology, and the special-purpose permanent magnetism transmission device in a kind of oil field that provides.
The special-purpose permanent magnetism transmission device in oil field of the present utility model, be to have fixed belt pulley at the motor power shaft, p-m rotor and belt pulley on the motor power shaft, have been fixed successively, at the outer gap covering device of p-m rotor conductor rotor, the conductor rotor seat is connected on the motor power shaft and with belt pulley.
As further improvement of the utility model, between conductor rotor and p-m rotor, leave the gap.
As further improvement of the utility model, p-m rotor and motor power shaft are fixed by the bolt I.
As further improvement of the utility model, the outlet side bearing block assembly of conductor rotor and motor power shaft is fixed by screw.
As further improvement of the utility model, be provided with dust cap at the bearing of motor power shaft.
The special-purpose permanent magnetism transmission device in the utility model oil field, magnetic actuator has the buffer starting function, impulse current time weak point during starting, little to the electrical network impact, energy consumption greatly reduces during starting.Reduce the impact to big machinery such as motor, gearbox, oil pumper simultaneously, prolonged the useful life of relevant device.The power factor of motor can significantly improve at work, alleviates the burden of electrical network and transformation, reduces line loss, has reduced reactive loss in a large number.
The special-purpose permanent magnetism transmission device in the utility model oil field, device structure is simple, failure rate is low, maintenance cost is low, reliability is high, long service life, easy for installation, do not need oil pumper is done any transformation, just can on existing oil pumper, directly install and use, simplify the Installation and Debugging process greatly, produced construction cost hardly.The user needs only original belt pulley on the motor is pulled down, and magnetic actuator is installed on the motor get final product.
The special-purpose permanent magnetism transmission device in the utility model oil field is mechanical device, almost irrelevant with electric power, when power quality is very poor, as voltage fluctuation, electric harmonic, flickering, fall, short time outage, thunderbolt, surge etc., these factors are fatal often to electronics or electric device.Adopt magnetic actuator neither can cause damage because of power quality, also can not cause shutdown.Magnetic actuator is adjusted the moment of torsion of transmission automatically with slippage, load torque more large-slip is more big, when the oil pumper discharge capacity is superfluous, will amplify slippage automatically and reduce the pump amount, otherwise when descending because there is not mechanical linkages to alleviate the potential load situation, can realize that the upper and lower stroke of equipment identifies automatically, thereby the motor running load characteristic of the upper and lower stroke of control oil pumper significantly improves power factor (PF).Because load characteristic was the potential load when oil pumper was descending, in using at the scene, will realize that speed uplink is slower than the comparatively ideal operation mode of downstream rate, has also improved pump efficiency, thereby has improved oil production in the coefficient of fullness that has improved pump.

Embodiment
Below in conjunction with the special-purpose permanent magnetism transmission device in 1 pair of the utility model oil field of accompanying drawing, be described further:
The special-purpose permanent magnetism transmission device in oil field of the present utility model, be on motor power shaft 1, to have fixed p-m rotor 3 and belt pulley 2 successively, at the outer gap covering device of p-m rotor 3 conductor rotor 4,4 of conductor rotor are connected on motor power shaft 1 and with belt pulley 2.
In this device, p-m rotor 3 and motor power shaft 1 are fixing by bolt I 5; The outlet side bearing block assembly 7 of conductor rotor 4 and motor power shaft 1 is fixing by screw 10; The outlet side bearing block assembly 7 of belt pulley 2 and motor power shaft 1 is fixing by bolt II 6.Bearing 8 at motor power shaft 1 is provided with dust cap 9; Be provided with nut 12 in the termination of motor power shaft 1.
Magnetic actuator mainly is made up of conductor rotor, p-m rotor two parts.P-m rotor is fixed on the motor power shaft, and also seat is on motor shaft by a bearing that plays a supportive role for conductor rotor, and conductor rotor is connected with the belt pulley one.Leave gap 11 between conductor rotor 4 and the p-m rotor 3, be called air gap, motor and load change soft (magnetic) link into by original hard (machinery) link like this, realize by the torque transfer of motor to load by the air gap between conductor and the permanent magnet.That is to say that the output speed of magnetic actuator is all little than input speed all the time, speed discrepancy is called slippage.In typical case, when motor completely changeed, the slippage of magnetic actuator was between 1%-4%.
The special-purpose permanent magnetism transmission device in the utility model oil field is to realize by motor to the torque transfer of loading with by the air gap between conductor and the permanent magnet, between motor and load, there is not mechanical attachment, automatically adjust the moment of torsion of transmission with slippage, has soft start function, the permission empty load of motor starts, not only reduced the starting current of motor and reduced to the thermal shock of motor load and to the influence of electrical network, thereby saves energy and the working life that prolongs motor, and when having reduced very effectively to start drive system to carrying the destructive tension force of adhesive tape, eliminated the vibration that produces when conveyer starts, can also alleviate the suffered startup of drive system itself significantly impacts, prolong adhesive tape, the useful life of critical components such as carrying roller, guaranteed the safe and reliable operation of equipment, reduced effectively maintenance of equipment and fault time cost.
